Guest: FN Global Community Rep,Andrew Chan

Host: Molly

Introduction:

Andrew:
Nice to meet you guys here,it's my honor to stand here speach for Filenet.Filenet(FN) is the world's first public chain of distributed storage application who has lauchned the mainet, and is also the world's first public chain of distributed storage application using DPOS + POC consensus mechanism.Filenet is dedicated to storing and distributing valuable content, rewarding miners in the form of mining to contribute idle bandwidth and storage. The mission of Filenet is to establish a powerful distributed data service system by connecting all idle storage to form, so any storage device that can connect to the Internet can participate in mining. Generally, Filenet is a super cloud system based on distributed storage and content sharing.

Questions from community:

Molly: Q1.What are the benefits of the FN project for business? What is the main role FN plays in business for five validation and security?
Andrew:
As we said just now,Filenet(FN) is the world's first public chain of distributed storage.
Filenet is dedicated to storing and distributing valuable content. The system provides a file promotion system. The more data is retrieved, the more popular it becomes, and the file can be mined.The DAO mechanism adopted by Filenet, in the system of Filenet, users need not pay for uploading and downloading, which greatly reduces the cost of enterprise server and bandwidth.Besides that Filenet is used to retrieve and distribute mining patterns, pledge a certain amount of deposit and provide a certain amount of storage space to participate in mining. The higher the miner's contribution, the higher the probability of a block.
Filenet is a leader in the field of distributed storage because of its unique consensus mechanism, business model, economic model, ecological strategy and governance structure, enabling blockchain storage to break out of the shackles and develop into a new format, and providing a key role for the development of other blockchain storage systems.
On the level of consensus, Filenet adopts the DPOS+POC mechanism as the consensus mechanism for distribution in the context of POC storage and mining, avoiding the direct contradiction between equipment efficiency and resource allocation, and greatly improving the mining mode in the blockchain 3.0 era.
The specific operation process of DPOS algorithm is that stakeholders, namely the Token holders and miners, vote to select Filenet Super Nodes through the election program, and then the Super Nodes in the block will be randomly pseudorandomly, and the Filenet Super Nodes can choose whether to produce blocks within a specified time.
As for smart contracts, Filenet is a common chain for developers that provides special programming primitives for DApp to interact with stored data.
These primitives are contained within the EVM (ethereum intelligent contract virtual machine). Thus, information about the location of data, storage nodes, and miners can also be accessed in smart contracts.
The world's first distributed storage DApp "Ztiao" developed based on Filenet network is now on the market. All chat data in this application will be stored in a fragmented form at any node in the world, transferred by private key, and the ecology in the application will be circulated and settled with Fn as payment token.
Filenet's smart contracts apply primarily to miners' coin holdings.The smart contracts we have developed may be rapidly realized through EVM (ethereum smart contract virtual machine) and solsea.
Filenet itself has the potential to implement an intelligent contract mechanism, and we believe that future versions of EVM and WASM will naturally integrate with the capabilities of Filenet and allow other main chains to benefit from Filenet.
In terms of data structure, the Filenet block saves all data trace parameters, and the data uploaded to Filenet is of various types and large quantities. While traditional linked list structures make blocks redundant and complex to express, Filenet USES a block chain data structure with Merkle tree and DAG (directed acyclic graph) structure.
The DAG structure is more flexible, more powerful, and faster than the traditional blockchain chain structure, greatly improving the efficiency of block packaging, thereby improving the performance of the Filenet network.
The Merkle tree does not require complete block information, but only the key Merkle node information to verify the block chain number filenet. IO page 10, a total of 24 data, which makes the node lighter and more energy and resources are devoted to business processing and providing services for the filenet network.
At the same time, Merkle tree can also simplify the verification process and further improve network performance.
Molly: Q2.Why does Filenet use the DPOS + POC consensus mechanism? What is the advantage?
Andrew:
As we all know,the core element of blockchain technology is the consensus mechanism. Currently, the most commonly used mechanisms include PoW (Proof-of-Work), PoS (Proof-of-Stake), DPoS (Delegated-Proof-of Stake), and PoC (Proof-of-Contribution). Proof of Work requires miners to solve complex cryptographic math problems and relies on computing power. The advantage of the system is that it is secure and reliable. Disadvantages are its limited capacity and the possibility of “51% attacks”. The Proof of Stake consensus mechanism selects miners according to how many coins he or she has. An immediate advantage is its low resource consumption. However, it opens itself to a range of attacks, such as nothing-at-stake, and also results in centralization since wealth brings more rewards and more decision-making power. In DPoS, the majority of people holding voting rights authorize a small number of nodes to act for them. The system’s merits are its high efficiency, throughput capacity and concurrency. However, the power is then concentrated in the hands of a few nodes, which is not safe. Proof of Contribution allocates mining and validating rights according to the contributions made by the nodes. The advantage of this system is that it does not waste resources thanks to its concept of selection based on resources provided to network. A disadvantage is that the calculation of contributions depends on specific scenarios. In the era of Blockchain 3.0, the consensus mechanisms are to advance under the principles of economy of resources, security focus and scalability, throughput capacity and concurrency.

Molly: Q3.What is the main reason behind the formation of FN? Why do you think coins like FN should be in the Marketplace?
Andrew:
As I just said,Filenet is an IPFS incentive layer to reward miners for sharing their storage and networking resources.
Filenet is also a token which powers a distributed certification mechanism. It creates a cloud-level system for content-sharing dedicated to storing and distributing valuable content on IPFS,demand leaders to results. Filenet solve the problem of data distribution and storage.Why coins like FN should be in the marketplace?
This is easy to understand,why bitcoin should be in the market?All coins can be in the market for just one reason-the consensus.If there just one person who think FN is valueble,we cannot say this is consesus,but if there is 10000,or 1 billion who make consesus,then you can say,FN should be in the market.Fn happens to have so many users make the consesus.The number of people in Filenet community has reached 210000+,the autonomy community is up to 21,the global super nodes is over 51+,Our community is still growing,our consensus is also deepening,because we all believe in the future of FN.In short term,in the mining mode, on the one hand: the tokens will be locked, and the decrease in circulation can increase the value of the token; on the other hand: mining can also generate income.
On the long term,Filenet can provide commercial applications with commercial value. Giant Internet companies such as Tencent WeSee and Byte Dance with giant data amount will have requirements for massive storage. Filenet can provide distributed storage services to solve the problem. Companies need to pay and lock FN for the distributed storage services. In this way, the circulation of FN on the market can be controlled, and thereby the value can be appreciated.
Molly: Q4.Can ordinary users also participate in mining? If can participate, how much mining can ordinary user do? And please explain the role of FN Coin easily.
Andrew:
Ordinary people can also participate in mining,as long as you pledge 400FN,and provide 4T storage space,you can join to mining.And the specific details depend on the mining pool you joined,you can see these pictures for a detailed mining tutorial.

Molly: Q5.What's the future plan of Filenet?
Andrew:
In the 1.0 stage, Filenet is the first distributed storage application public chain on the mainnet, the first distributed storage application public chain on the exchange, and the first distributed storage application public chain using the DPOS + POC consensus mechanism.
Filenet 2.0 comprehensively solves the key shortcomings of centralized data service centers.
In Filenet3.0 stage, the vision can catch up with and surpass many leading projects and brands of the decentralized distributed storage track, such as Filecoin, IBM, Amazon, Maidsafe, and become the leader of the track.

Powerful New Ethereum Miner Reaches Final Stage Before Mass Production

Powerful New Ethereum Miner Reaches Final Stage Before Mass Production

https://preview.redd.it/ao78avnae4m31.png?width=860&format=png&auto=webp&s=11f62e6227dc7d93e9a6c2c3874782fcd4892b59
News by Coindesk: Wolfie Zhao
After a nine-month delay and $3.8 million of investment, an upstart manufacturer is ready to produce its first batch of powerful new machines for mining cryptocurrencies ethereum and ethereum classic.
Linzhi, based in Shenzen, China, said Wednesday it had ordered 37 wafers from Taiwan Semiconductor Manufacturing Company, the main parts that will allow it to build about 200 application-specific integrated circuit (ASIC) miners.
These sample units will test whether the machines can mine as efficiently as they are designed to do using ethash, the proof-of-work algorithm used on ethereum and ethereum classic.
The testing units, if successful, would mark a major step toward mass production as Linzhi sets out to compete with makers of general-purpose computing chips, such as NIVIDA, as well as mining gear specialists Bitmain and InnoSilicon, which both make ASIC miners for the ethash algorithm.
Roughly five million ether (ETH), the native cryptocurrency on the ethereum network, is being mined every year, which, at its current price, is worth more than $800 million. Even for ethereum classic, which maintains the original ethereum ledger from before a hard fork in 2016, about nine million native ETC gets mined every year, worth more than $60 million.

Powerful chips

Linzhi was founded in February 2018 by Chen Min, a former chip design head at Canaan Creative, maker of the Avalon bitcoin miner. Chen told CoinDesk the new company was completely self-funded with about $4 million as starting capital.
It announced the plan to produce ethash ASIC miners in September 2018 with an ambition to beat the efficiency of most existing equipment. Chen’s target specification for Linzhi’s ethash ASIC miner is set at 1400 mega hashes per second (MH/s) with an electricity consumption level of one kilowatt-hour.
To put those figures in perspective, NVIDIA’s GTX TitanV 8 card is now one of the most profitable piece of equipment on the ethash algorithm, able to compute 656 MH/s at an energy consumption level of 2.1 kWh, according to mining pool f2pool’s miner profitability index,
With ETH’s current price ($180) and network difficulty, as well as an electricity cost of $0.04 per kWh, each GTX TitanV 8 would bring home a daily profit of $7.35. Similarly, if one uses the same GTX TitanV 8 card to mine ETC, which has both a lower price and a lower mining difficulty than ETH, the daily profit would still be around $6.70.
The total computing power racing on ethereum and ethereum classic to compete for block rewards and to secure the two networks is around 160 and 13 tera hashes per second (TH/s), respectively.

Plan A

Since the announcement of its plan, Linzhi has spent almost all of its initial capital on research and development of the chip design, the operations of its dozen-person team, and the order of the first batch of wafers, to bet the sample testing units will deliver the intended mining power.
Linzhi previously said it was aiming to order the first batch of wafers around December in order to have samples ready in April and mass production in June.
Speaking of the delay, the company said:
“We underestimated the complexity of the chip and how long it would take to grow the team and make the company functional. We are cautiously optimistic that we can just move forward the rest of the schedule, which would mean 12/2019 for sample machines and 02/2020 for mass production.”
One possible risk for the business is that the ethereum community has previously voted to activate the so-called ProgPow algorithm in order to remove the edge maintained by large miners that can afford expensive, specialized chips, although the timing for that switch is not yet decided. (Eventually, ethereum developers want to transition from proof-of-work to proof-of-stake, which would eliminate mining altogether.)
When asked if Linzhi has any Plan B if the switch happens, Chen said the company is, in fact, more active in the ETC community, adding:
“Our plan A is to focus on ETC mining. So if ETH will still be an option, that’s something good to have. In the ethereum community, the ProgPow plan still has some uncertainty. For the time being, we don’t see it as a market that we will obtain, so I don’t really care that much.”

Reverse discount

In an arguably counterintuitive move, Chen said the company plans to adopt what it calls a “reverse discount” strategy when it starts to take in pre-orders if sample units prove to be successful. That would mean the more you buy, the more you are likely going to pay.
The reason is to discourage any single entity from buying too many machines and thus concentrating power over the network.
While Linzhi has not yet decided on final pricing for each unit to be sold at pre-orders, it says the goal is to achieve a payback period of four months for individual miners with a relatively small number of orders.
“This is our efforts and contribution to the idea of decentralization,” Chen said, concluding:
“Our sales will go to developers and community first, with a focus on geographical distribution, and potentially with a malus [reverse discount] for large orders. This means that small orders by individuals would be priced to hit the 4 month [return of investment] and larger orders would pay more.”

decentralized pooling

Like the rest of you, I became interested in XMR because of it focus on privacy and decentralization. But, its not practical for many of us to mine without pooling. Is there any technical or other reason that pooling couldn't be "built-in" as part of the general protocol? In other words, there would be one pool that all miners participate in, where just like a pool, payouts are may based on your hash rate contribution and no more lottery type payouts.
If it is possible, could there be a distribution alogo that would "adjust" (much like the difficulty adjusts), such that if the network could reduce the payouts to the high power miners based on some measurement of the concentration of higher power miners.
I don't really like the concept of the second question, but I'm just concerned that if RandomX fails, then XMR is eventually going to become centralized like bitcoin. So, maybe there is some other way to address centralization then just through the mining algo.

Nodes vs. Mining - Is bitcoin still resilient today?

Hi bitcoin folks,
I have been reading a lot about bitcoin and still haven't got the answer to one question in my head: could bitcoin today not already be very easily destroyed by an authoritarian government taking control over few mining farms?
Let me give you my underlying understanding of bitcoin fundamentals first (and let you verify whether these are correct):
- In the original bitcoin concept by Santoshi, nodes are all be mining; decentralized mining + PoWs are a fundamental source of resilience for the bitcoin design overall (no single player controlling enough of the bitcoin system overall to impair it)
- today, because of the increased difficulty of mining, nodes usually don't mine anymore, but this is done by big mining farms with specialized hardware such as ASICs.
- some of the mining farms have massive combined power, and the biggest mining pools are concentrated (as predicted by Santoshi) in some areas where electricity is cheap to obtain; these areas of concentration happen to be also geographically in tightly politically controlled areas, i.e. china, russia. most people believe that the governments in these areas would have no difficulty forcing any company, individual or institution to follow their orders. hence, the miners or mining pool operators sitting in these geographies would obey such orders if pushed this direction by a secret service, government institution, etc.
- it is already seen that the combined mining power exceeds 50% of the total capacity in china (although not in one mining pool, multiple mining pools operating out of china are believed to have that power). without that capacity, there are no new blocks, and no transactions possible on the bitcoin network.
- miners themselves would not have an interest in destroying bitcoin (e.g. by 51% attack), as they have massively invested in it, as Santoshi has foreseen. but a government or government agency would already be able to take this influence over large pools and their miners at any point in time, and may have an interest in destroying or impairing bitcoin. effectively this means, mining power is centrally controllable easily for them (even if not controlled today)?
- it is highly unlikely that the unbalanced mining power distribution (with few very powerful mining players possessing the hardware) will ever reverse, since ASICs have emerged and such massive combined computing power is out there; while the bitcoin design still allows computing with ordinary desktop computers (block size and resulting memory etc. needs were designed that way), the difficulty is already so high that nobody does it anymore
My question is:
How would regular bitcoin nodes - such as nodes run on people's own, single machines - have any chance to maintain resilience of the network then as designed by Santoshi? Specifically: how is abuse of the centrally controlled mining power at all avoidable in today's reality, e.g. aiming at destabilizing or destroying the bitcoin system?
I would understand the future of bitcoin is basically already in the hands of those who could - if they wanted - take control over the majority of the mining hardware out there for it.
I am curious to hear your thoughts about this.

Overview of Major Risks of Buying Nyancoins - Version 6

This is the sixth version of the NYAN risks document (based on v5 (v4 (v3 , v2 and original)). These are obsoleted periodically as the old ones get archived to allow for comments again via a new post, to re-examine the risks in light of changes, and for greater visibility.
The purpose of these documents is to provide a best-effort discussion of major risk factors in gambling on NYAN, modeled on the risks disclosure in a 10k (annual report) which is mandated for publicly traded companies in the United States. This document is provided with no guarantee that major risk factors have not been missed, and it is important to recognize my (coinaday) personal bias from holding about one-third of the total supply of NYAN.
Please comment on any risks which are not mentioned here or additional aspects of risks here you think should be further emphasized or any other possible disclosure you think would be helpful to a person considering gambling on NYAN.
Executive summary
Nyancoins have no exchange, no core developer at the moment, uncertain demand, have had inconsistent blocks, are very vulnerable to 51% attacks, have the potential for serious bugs, an uncertain legal situation, concentrated ownership, low liquidity, depend upon the Internet, may be addictive, and could make you wealthy, which has been alleged to lead to more problems.
Introduction: This is my best attempt to collect every major risk factor from buying Nyancoins, although I can offer no warranty of fitness for this information for any purposes. I believe in honesty and forthrightness. Having this available and obvious is a simple matter of basic decency. Much, hopefully all, of this information has been discussed previously in /nyancoins, but this document in particular is about being up-to-date and central. This page will be updated clearly as appropriate if situations change on a best-effort basis (which may mean updates do not happen for months at times, unfortunately; please ping for faster updates).
If you believe that I am missing something, please note any other major risks you see in the comments.
Exchanges:
Nyancoins are not currently traded on any exchange. It may be listed on one minor exchange but have no volume there. Obviously an unlisted cryptocurrency is in a bad situation. I hope to see us gain a listing on an exchange which supports low volume coins in 2020 but I have no current prospect of this and it should be considered a longshot at best.
Previously we traded on Trade Satoshi and prior to that on Cryptopia and prior to that on Cryptsy. All three exchanges failed us (Trade Satoshi delisted without allowing withdrawal; Cryptopia delisted and failed to provide withdrawal and then went bankrupt; Cryptsy went bankrupt). This is a further reminder that exchanges are a major risk and one should be extremely careful to not keep more coins on there than one can comfortably afford to lose.
In theory, there are decentralized exchange technologies, notably CATE; however, I think we currently lack some needed APIs for this. I'm not certain but we haven't demonstrated the capability yet. On-Reddit exchanges are also possible with tipbots, but require trust as they are not atomic. It should be possible to build an "exchangebot" similarly, although I'm not currently aware of one, but my concept would still have the bot as a trusted central party.
Atomic cross-chain transactions seem to me like a very promising core technology ultimately for building exchanges which can be more proveably secure. They could also allow exchanges to share a common listing protocol as well without having to trust the other exchanges (at least, beyond the core protocol development and maintenance; tanstaafl). This is not yet accomplished though and in the meantime we remain vulnerable to periodic exchange failures.
Core developer: Although we have good general tech support in this community and have put up supporting infrastructure, there is not anyone officially currently working on core client code. This is a significant problem for the long-term, although we are not in any immediate known need of changes.
ImASharkRawwwr has returned to the community and may do future client updates, but I'm leaving the lack of core developer risk unchanged until there is an update released. This is not intended as a slight in any way but merely being cautious in the risks document and recognizing that we aren't certain when or if there will be a next release.
Demand: NYAN was introduced in 2014 and during the second half of that year had so little demand that it almost died out. In January 2015 I got involved in the coin and for most of 2015 and 2016 I was the majority of the buying pressure. I base these statements on my recollection of the trading history so far and the fact that I have acquired more than 120 million coins, somewhere around 41% of the coins (latest hodling report, June 2017), as well as my observations that I had usually had the leading major bid, and usually the leading bid regardless of size.
In 2017, I have generally not been a major factor in the demand, as I haven’t had money to spare to gamble on NYAN. In June 2017, we have had a spike in buying from an unknown source.
It is unknown whether significant demand for NYAN will continue. Because its value is purely speculative, it is entirely possible that demand for NYAN could simply end. This is a fundamental risk in gambling on NYAN; it is entirely possible that its value will go to zero and not recover.
By the end of 2019, we lost exchange listing. I know of no current demand for NYAN. I hope to see us listed and demand exist in the future but should not be relied upon. NYAN last traded around 9 satoshi according to coinmarketcap but it may well not even trade that high even if relisted someday - there could be a flood of selling and no buyers.
Inconsistent blocks:
Although NYAN is designed to produce a block every minute, there have been times where there has been more than 24 hours between blocks. This results because of an imperfect difficulty function and low base hashing, along with price fluctuations, which can combine to have a low difficulty making the coin attractive for a flood of hashing power which can lead the difficulty function to overcompensate, leaving it stuck with a high difficulty no longer profitable to mine.
I haven’t observed this lately, that is, I don’t recall incidents of this in 2017, but I’ve been paying far less attention to it as well. It is entirely possible for this to recur, as the difficulty function is not fixed (it would require a hard fork to fix it). We seem to have more baseline hashing which helps to avoid this, but it is possible for us to lose that.
A workaround is to use large transaction fees (I've set my client to 337 NYAN) which is enough to cause pools to generally solve a block even if the chain were otherwise stuck. It may be possible to include a better difficulty function in a hard fork client, but it is unknown when if ever this would be done and it's not yet clear what design improvement if any would fix this.
51% attack: Because of the generally quite low hashing power on NYAN, it is highly vulnerable to a 51% attack. Either a leading pool or a new one could choose to do a denial-of-service attack, whether for extortion, lulz, or some other reason (like coinaday being annoying). Such an attack is capable of preventing any transaction processing for as long as it is sustained. I consider this a relatively low risk since I expect we would simply wait it out (and potentially not even notice such an attack for quite a while given the low volume of transactions currently), but it is definitely a potential vulnerability.
Bugs: It is possible that there are bugs in the underlying code. I have never read through all of the bitcoin or nyancoin code, of any version, nor even studied the original bitcoin whitepaper in depth (by the way, we oughta make up a nyancoin whitepaper or ten someday), meaning I have no professional or technical knowledge about whether or not the system is fundamentally sound. I've been going based on "it seems to be working, so it's probably fine", which is, shall we say, more of an engineering than scientific approach.
I have heard reference to a "time warp" bug vulnerability in the KGW difficulty function which Nyancoins has. I do not know details and my understanding is a fix to this would require a fork to change the difficulty function, so I do not anticipate a fix before NYAN3, the term for an eventual hard fork, but it is unknown when if ever this would be done. I consider this vulnerability to be likely to be related to the fundamental weakness to difficulty spikes after large amounts of hashing jumps on the network. Hostile (or simply passing interest with large capacity) hashing does degrade the performance of the network. As a workaround, this class of attack can be mitigated with a transaction to 'unstick' the chain after, since the difficulty function will adjust in the next block after enough wall-time has passed since the last block (so only need one high difficulty solve which can be triggered by a transaction fee).
Legal: Bitcoin faces uncertain legal situations in almost every country. Nyancoin is even more uncertain, as people tend to consider bitcoin and not address impacts on altcoins. Between the potential tax implications and banking regulations and currency laws, there are a wide variety of ways a person could make a felony-level mistake. This can be somewhat mitigated by merely buying and holding, as you won't be responsible for KYC/AML presumably (although an argument could be made in your purchase), and presumably unrealized capital gains wouldn't be taxable (but I am neither a lawyer nor accountant nor any sort of expert on the relevant accounting laws in any country).
Somehow getting legal opinions for Nyancoins in every country would be very useful in my opinion. If Bitcoin and altcoins are well-studied in a given country it should be relatively easy to adapt those opinions and research to Nyancoins, but it would still require some pro bono work in any case. So...hopefully we'll get some lawyer Nekonauts someday who are willing to semi-officially give us an opinion. In the meantime...hope that common sense can save you. If you sell Nyancoins directly, you're going to need to comply with the KYC/AML types of laws of your country. If you're going to do banking operations...may the central bank have mercy on your soul.
I think the best advantage we have is the same bitcoin had for its first years: we're too small for anyone to care. But since we plan to grow significantly, we need to be aware of our legal issues upon scale. Which is to say, whether or not you're allowed to sell 10,000 NYAN to your friend probably has a lot to do with whether your friend legally acquired whatever is being offered in exchange, and whether the value of what you get in return is above a certain level or not. I'm not going to try guessing that level precisely because I know I'll be wrong. $1 is probably fine. $10,000 is probably illegal without some significant licensing. I would suggest either not touching fiat or else deliberately capping it without verification after getting an independent local expert legal opinion.
concentration: The fact that I hold about 41%(? not sure the exact percentage as of Dec 2017 ; need to do updated survey to check; 41% sounds slightly high to me but I'll see...I'll try to update by the end of the year or shortly after) of the currently outstanding NYAN could be a major risk factor, particularly if I do not act in the best long-term interests of the strength of Nyancoins. For instance, I could pull my bids, sell only a small part of my holdings, crash the market, and potentially buy a lot of volume for a lower price. While I cannot foresee any circumstance under which I would do this, it is certainly conceivable that I could be financially, legally, or morally obligated to do so if I were to become insolvent.
Liquidity: There is very little trading activity in NYAN. Therefore, large purchases will drive the price up and large sales will drive the price down. This means that entering and exiting a position is likely to result in "slippage", so even if the price has increased slightly overall since the time before one entered a position to the time before one exits it, it is quite possible that the overall trade will be neutral or negative as a result of the pressure on the market. For an extreme example, my own position would be essentially impossible to exit from the market without crashing the price, and even so it would likely be difficult to find buyers even at a satoshi, based on that I currently am the majority of the bids on the market. This is closely tied to the concentration risk but if I were to exit NYAN for any reason or simply fail to continue to renew bids the liquidity would dry up even further.
At the end of 2019, having no exchange, there is functionally zero liquidity. In theory peer to peer trading could still be done but I’m unaware of any.
Internet outage: if the Internet goes down, we hit a very nasty scenario. We can't process transactions, and all the miners go into a race to make 'useless' blocks on their own. If the Internet were never to come back up, Nyancoins would be dead. If there is a daylong internet outage, the longest blockchain discovered after, presumably representing the most hashing power dedicated to empty blocks during that outage, will win. So I suppose the block rewards in that case are for having the faith in Nyancoins to keep hashing and storing the blockchain during the day without the Internet.
addictive: This was a curiosity to me when I started. Now it's an obsession for me. I'm constantly thinking about how I can help to smooth the path for Nyancoins to grow stronger and better and more valuable. You may find that once you start to realize the impact you can have upon Nyancoins, and that Nyancoins can have upon you, that you start to become addicted as well. It is possible to substitute another addiction in its place, such as dogecoins or pcp, but it is not recommended.
Nyancoin addictions are considered 'mostly harmless'. The exception is if you go 'full coinaday' and start to accumulate more than 10% of your assets in Nyancoins. In this, this is essentially a variety of gambling addiction. I would argue that it beats roulette because you can tilt the odds in your favor, but then, I would argue that, wouldn't I?
mo' nyan mo' problems: Some people have claimed that more money leads to more problems. Since nyan is money, it follows as a consequence of the conjecture. Should this be the case, your increasing nyan could potentially lead to such problems in the future as: enhanced attention from revenue collection services of all kinds (governmental and private), swarms of fake friends and gold-diggers, excessive risk-taking as a result of feelings of invincibility, an increase in certain varieties of targeted marketing, possible disqualification for asset-based welfare for you (or even your children, for instance college financial assistance), an inability to remember how many houses you own, or other serious problems.
Conclusion
The lack of any exchange trading Nyancoins is a major risk factor in its future survival. If it is listed, the lack of development is likely the next most serious. The coin currently survives but whether it will continue to do so in the future is far from certain. If those of us who have found or come back to NYAN choose to keep it alive, I believe it still has a chance at surviving into a stronger future.

Tacotime mentioned a hard fork proposal to never let the block reward drop below 1 coin:
Code: if (blockReward < 1){ blockReward = 1; }
I assume this is merely delaying the problem, however. I proposed a fixed annual debasement (say 2%) with a tx fee cap of like 0.001% of the current block reward (or whatever sounds reasonable). That way we still get the spam protection without worrying about fee escalation down the road."

-2059: I was skeptical of this conspiracy theory at first but after thinking about the numbers and looking back at the code again, I'm starting to believe it.
These are not deep optimizations, just cleaning up the code to work as intended.
At 100 H/s, with 500k iterations, 70 cycles per L3 memory access, we're now at 3.5 GHz which is reasonably close. So the algorithm is finally memory-bound, as it was originally intended to be. But as delivered by the bytecode developers not even close.
I know this is going to sound like tooting our own horn but this is another example of the kind of dirty tricks you can expect from the 80% premine crowd and the good work being done in the name of the community by the Monero developers.
Assuming they had the reasonable, and not deoptimized, implementation of the algorithm as designed all along (which is likely), the alleged "two year history" of bytecoin was mined on 4-8 PCs. It's really one of the shadiest and sleaziest premines scams yet, though this shouldn't be surprising because in every type of scam, the scams always get sneakier and more deceptive over time (the simple ones no longer work)."

Everyone focuses on botnets because it has been so long since regular users were able to effectively mine a coin (due to every coin rapidly going high end GPU and ASIC) that the idea that "users" could vastly outnumber "miners" (botnet or otherwise) isn't even on the radar.
The vision here is a wallet that asks you when you want to install: "Do you want to devote some of you CPU power to help secure the network. You will be eligible to receive free coins as a reward (recommended) [check box]." Get millions of users doing that and it will drive down the value of mining to where neither botnets nor professional/industrial miners will bother, and Satoshi's original vision of a true p2p currency will be realized.

Other coins do use the word anonymous improperly, so we too have to play the marketing game. Most users will not bother looking at details to see which actually has more privacy; they'll assume anonymity > privacy. In a world with finite population, there's no such thing as anonymity. You're always "1 of N" possible participants.
Zero knowledge gives N -> everyone using the currency, ring signatures give N -> your choice, and CoinJoin gives N -> people who happen to be spending around the same amount of money as you at around the same time. This is actually the critical weakness of CoinJoin: the anonymity set is small and it's fairly susceptible to blockchain analysis. Its main advantage is that you can stick to Bitcoin without hard forking.
Another calculated marketing decision: I made most of the OP about ring signatures. In reality, stealth addressing (i.e. one-time public keys) already provides you with 90% of the privacy you need. Ring signatures are more of a trump card that cannot be broken. But Bitcoin already has manual stealth addressing so the distinguishing technological factor in CryptoNote is the use of ring signatures.
This is why I think having a coin based on CoinJoin is silly: Bitcoin already has some privacy if you care enough. A separate currency needs to go way beyond mediocre privacy improvements and provide true indistinguishably. This is true thanks to ring signatures: you can never break the 1/N probability of guessing correctly. There's no additional circumstantial evidence like with CoinJoin (save for IP addresses, but that's a problem independent of cryptocurrencies)."

  • Fast curve emission non-bitcoin-like curve as initially advertised and as it was widely accepted as suitable
Though we have to say two things to support current Monero community and devs:
  • The crippled miner was coded either by Bytecoin or CryptoNote, and 100% solved within a month by Monero community
  • The fast curve emission was a TFT miscalculation. He forgot to consider that as he was halving the block target he was unintentionally doubling the emission rate.

Bitmex CEO calls BTC bottom at $5000, says ETH headed for sub-$100

On BTC:
My hunch tells me that similar to the 2015 bear market, the price at which the average miner turns off their ASICs will be the local bottom.
During the last bear market that range was $200 - $250. While the price languished, various high profile miners went under. KnC and Spondoolies were two casualties. Most surprisingly, in March of 2015 the difficulty actually dropped. That was 7 months before the price ticked up, but it illustrates the amount of pain that miners faced.
Now assuming there is no positive catalyst, like an SEC approved ETF to save us, at what price do we bottom? I believe the key consideration will be when miners begin to shut off their machines; and hence the question, what is the marginal cost of a Bitcoin?
A few days ago I chatted with one of the largest mining facility operators globally. He told me that the average electricity cost of Chinese miners all-in is 6 to 7 cents kWh. At that level, he estimated that at a price of roughly $5,000 is when miners would begin altering operations and look to move machines to cheaper areas. At $3,000 to $4,000, these miners would begin to shut off machines completely.
On the concentration risk of ETH:
So instead of a more dispersed pool of investors, the number of token holders of projects raising serious money decreased dramatically starting in mid-2017. The liquidation preferences went from dispersed along a price curve, to very concentrated.
VCs all compete with each other for the same pools of capital. These pools of capital all employ professionals from the same schools, and who passed the same financial certification tests. Therefore they will buy together and sell together. The biggest risk in the money management game is career risk. Better to lose money with everyone else, than lose money alone. The latter will cost you your job. And there ain’t no other profession that pays as well as financial services relative to the skills needed to be a practitioner. I remember one of my besties trying to argue he had skills because he could calculate the NAV of an ETF using the sumproduct() function on his excel sheet. #Delusional.
The herd of token VC punters will all decide to sell at the same time. If you don’t sell, and the market continues falling, you lose your job. So everyone sells simultaneously but who can eat all that shit? Retail cannot because the deals would never have gotten so large without institutional money. So we gap lower, first on tokens, then on the mothership Ether.
I don’t know what that tipping point will be, but in hindsight, it will be obvious when the capitulation occurs. There are those who believe that a sustainable token economy can exist. But they won’t be buying at these levels. Sub-$100 takes us back to Spring 2017 levels. At those depressed prices, the carrion is ripe for ingestion.

Overview of Major Risks of Buying Nyancoins - Version 5

This is the fifth version of the NYAN risks document (based on v4 (v3 , v2 and original). These are obsoleted periodically as the old ones get archived to allow for comments again via a new post, to re-examine the risks in light of changes, and for greater visibility.
The purpose of these documents is to provide a best-effort discussion of major risk factors in gambling on NYAN, modeled on the risks disclosure in a 10k (annual report) which is mandated for publicly traded companies in the United States. This document is provided with no guarantee that major risk factors have not been missed, and it is important to recognize my (coinaday) personal bias from holding about one-third of the total supply of NYAN.
Please comment on any risks which are not mentioned here or additional aspects of risks here you think should be further emphasized or any other possible disclosure you think would be helpful to a person considering gambling on NYAN.
Executive summary
Nyancoins have no core developer at the moment, uncertain demand, are traded actively on only one exchange, have had inconsistent blocks, are very vulnerable to 51% attacks, have the potential for serious bugs, an uncertain legal situation, concentrated ownership, low liquidity, depend upon the Internet, may be addictive, and could make you wealthy, which has been alleged to lead to more problems.
Introduction: This is my best attempt to collect every major risk factor from buying Nyancoins, although I can offer no warranty of fitness for this information for any purposes. I believe in honesty and forthrightness. Having this available and obvious is a simple matter of basic decency. Much, hopefully all, of this information has been discussed previously in /nyancoins, but this document in particular is about being up-to-date and central. This page will be updated clearly as appropriate if situations change on a best-effort basis (which may mean updates do not happen for months at times, unfortunately; please ping for faster updates).
If you believe that I am missing something, please note any other major risks you see in the comments.
Core developer: Although we have good general tech support in this community and have put up supporting infrastructure, there is not anyone officially currently working on core client code. This is a significant problem for the long-term, although we are not in any immediate known need of changes.
ImASharkRawwwr has returned to the community and may do future client updates, but I'm leaving the lack of core developer risk unchanged until there is an update released. This is not intended as a slight in any way but merely being cautious in the risks document and recognizing that we aren't certain when or if there will be a next release.
Demand: NYAN was introduced in 2014 and during the second half of that year had so little demand that it almost died out. In January 2015 I got involved in the coin and for most of 2015 and 2016 I was the majority of the buying pressure. I base these statements on my recollection of the trading history so far and the fact that I have acquired more than 120 million coins, somewhere around 41% of the coins (latest hodling report, June 2017), as well as my observations that I had usually had the leading major bid, and usually the leading bid regardless of size.
In 2017, I have generally not been a major factor in the demand, as I haven’t had money to spare to gamble on NYAN. In June 2017, we have had a spike in buying from an unknown source.
It is unknown whether significant demand for NYAN will continue. Because its value is purely speculative, it is entirely possible that demand for NYAN could simply end. This is a fundamental risk in gambling on NYAN; it is entirely possible that its value will go to zero and not recover.
Exchanges:
Trade Satoshi is currently the only exchange for Nyancoins with significant volume. If Trade Satoshi were to fail somehow, it is likely that this would have significant consequences for Nyancoins.
Previously we traded on Cryptopia and prior to that on Cryptsy. Both exchanges failed. This is a further reminder that exchanges are a major risk and one should be extremely careful to not keep more coins on there than one can comfortably afford to lose.
In theory, there are decentralized exchange technologies, notably CATE; however, I think we currently lack some needed APIs for this. I'm not certain but we haven't demonstrated the capability yet. On-Reddit exchanges are also possible with tipbots, but require trust as they are not atomic. It should be possible to build an "exchangebot" similarly, although I'm not currently aware of one, but my concept would still have the bot as a trusted central party.
Atomic cross-chain transactions seem to me like a very promising core technology ultimately for building exchanges which can be more proveably secure. They could also allow exchanges to share a common listing protocol as well without having to trust the other exchanges (at least, beyond the core protocol development and maintenance; tanstaafl). This is not yet accomplished though and in the meantime we remain vulnerable to periodic exchange failures.
Inconsistent blocks:
Although NYAN is designed to produce a block every minute, there have been times where there has been more than 24 hours between blocks. This results because of an imperfect difficulty function and low base hashing, along with price fluctuations, which can combine to have a low difficulty making the coin attractive for a flood of hashing power which can lead the difficulty function to overcompensate, leaving it stuck with a high difficulty no longer profitable to mine.
I haven’t observed this lately, that is, I don’t recall incidents of this in 2017, but I’ve been paying far less attention to it as well. It is entirely possible for this to recur, as the difficulty function is not fixed (it would require a hard fork to fix it). We seem to have more baseline hashing which helps to avoid this, but it is possible for us to lose that.
A workaround is to use large transaction fees (I've set my client to 337 NYAN) which is enough to cause pools to generally solve a block even if the chain were otherwise stuck. It may be possible to include a better difficulty function in a hard fork client, but it is unknown when if ever this would be done and it's not yet clear what design improvement if any would fix this.
51% attack: Because of the generally quite low hashing power on NYAN, it is highly vulnerable to a 51% attack. Either a leading pool or a new one could choose to do a denial-of-service attack, whether for extortion, lulz, or some other reason (like coinaday being annoying). Such an attack is capable of preventing any transaction processing for as long as it is sustained. I consider this a relatively low risk since I expect we would simply wait it out (and potentially not even notice such an attack for quite a while given the low volume of transactions currently), but it is definitely a potential vulnerability.
Bugs: It is possible that there are bugs in the underlying code. I have never read through all of the bitcoin or nyancoin code, of any version, nor even studied the original bitcoin whitepaper in depth (by the way, we oughta make up a nyancoin whitepaper or ten someday), meaning I have no professional or technical knowledge about whether or not the system is fundamentally sound. I've been going based on "it seems to be working, so it's probably fine", which is, shall we say, more of an engineering than scientific approach.
I have heard reference to a "time warp" bug vulnerability in the KGW difficulty function which Nyancoins has. I do not know details and my understanding is a fix to this would require a fork to change the difficulty function, so I do not anticipate a fix before NYAN3, the term for an eventual hard fork, but it is unknown when if ever this would be done. I consider this vulnerability to be likely to be related to the fundamental weakness to difficulty spikes after large amounts of hashing jumps on the network. Hostile (or simply passing interest with large capacity) hashing does degrade the performance of the network. As a workaround, this class of attack can be mitigated with a transaction to 'unstick' the chain after, since the difficulty function will adjust in the next block after enough wall-time has passed since the last block (so only need one high difficulty solve which can be triggered by a transaction fee).
Legal: Bitcoin faces uncertain legal situations in almost every country. Nyancoin is even more uncertain, as people tend to consider bitcoin and not address impacts on altcoins. Between the potential tax implications and banking regulations and currency laws, there are a wide variety of ways a person could make a felony-level mistake. This can be somewhat mitigated by merely buying and holding, as you won't be responsible for KYC/AML presumably (although an argument could be made in your purchase), and presumably unrealized capital gains wouldn't be taxable (but I am neither a lawyer nor accountant nor any sort of expert on the relevant accounting laws in any country).
Somehow getting legal opinions for Nyancoins in every country would be very useful in my opinion. If Bitcoin and altcoins are well-studied in a given country it should be relatively easy to adapt those opinions and research to Nyancoins, but it would still require some pro bono work in any case. So...hopefully we'll get some lawyer Nekonauts someday who are willing to semi-officially give us an opinion. In the meantime...hope that common sense can save you. If you sell Nyancoins directly, you're going to need to comply with the KYC/AML types of laws of your country. If you're going to do banking operations...may the central bank have mercy on your soul.
I think the best advantage we have is the same bitcoin had for its first years: we're too small for anyone to care. But since we plan to grow significantly, we need to be aware of our legal issues upon scale. Which is to say, whether or not you're allowed to sell 10,000 NYAN to your friend probably has a lot to do with whether your friend legally acquired whatever is being offered in exchange, and whether the value of what you get in return is above a certain level or not. I'm not going to try guessing that level precisely because I know I'll be wrong. $1 is probably fine. $10,000 is probably illegal without some significant licensing. I would suggest either not touching fiat or else deliberately capping it without verification after getting an independent local expert legal opinion.
concentration: The fact that I hold about 41%(? not sure the exact percentage as of Dec 2017 ; need to do updated survey to check; 41% sounds slightly high to me but I'll see...I'll try to update by the end of the year or shortly after) of the currently outstanding NYAN could be a major risk factor, particularly if I do not act in the best long-term interests of the strength of Nyancoins. For instance, I could pull my bids, sell only a small part of my holdings, crash the market, and potentially buy a lot of volume for a lower price. While I cannot foresee any circumstance under which I would do this, it is certainly conceivable that I could be financially, legally, or morally obligated to do so if I were to become insolvent.
Liquidity: There is very little trading activity in NYAN. Therefore, large purchases will drive the price up and large sales will drive the price down. This means that entering and exiting a position is likely to result in "slippage", so even if the price has increased slightly overall since the time before one entered a position to the time before one exits it, it is quite possible that the overall trade will be neutral or negative as a result of the pressure on the market. For an extreme example, my own position would be essentially impossible to exit from the market without crashing the price, and even so it would likely be difficult to find buyers even at a satoshi, based on that I currently am the majority of the bids on the market. This is closely tied to the concentration risk but if I were to exit NYAN for any reason or simply fail to continue to renew bids the liquidity would dry up even further.
Internet outage: if the Internet goes down, we hit a very nasty scenario. We can't process transactions, and all the miners go into a race to make 'useless' blocks on their own. If the Internet were never to come back up, Nyancoins would be dead. If there is a daylong internet outage, the longest blockchain discovered after, presumably representing the most hashing power dedicated to empty blocks during that outage, will win. So I suppose the block rewards in that case are for having the faith in Nyancoins to keep hashing and storing the blockchain during the day without the Internet.
addictive: This was a curiosity to me when I started. Now it's an obsession for me. I'm constantly thinking about how I can help to smooth the path for Nyancoins to grow stronger and better and more valuable. You may find that once you start to realize the impact you can have upon Nyancoins, and that Nyancoins can have upon you, that you start to become addicted as well. It is possible to substitute another addiction in its place, such as dogecoins or pcp, but it is not recommended.
Nyancoin addictions are considered 'mostly harmless'. The exception is if you go 'full coinaday' and start to accumulate more than 10% of your assets in Nyancoins. In this, this is essentially a variety of gambling addiction. I would argue that it beats roulette because you can tilt the odds in your favor, but then, I would argue that, wouldn't I?
mo' nyan mo' problems: Some people have claimed that more money leads to more problems. Since nyan is money, it follows as a consequence of the conjecture. Should this be the case, your increasing nyan could potentially lead to such problems in the future as: enhanced attention from revenue collection services of all kinds (governmental and private), swarms of fake friends and gold-diggers, excessive risk-taking as a result of feelings of invincibility, an increase in certain varieties of targeted marketing, possible disqualification for asset-based welfare for you (or even your children, for instance college financial assistance), an inability to remember how many houses you own, or other serious problems.
Conclusion
There are a variety of different risks in buying Nyancoins. I believe the most serious one is the developer issue. If those of us who have found or come back to NYAN abandon it, it could die. Otherwise, I consider the risks generally manageable, but exchange failure or a currently unknown bug could do serious damage to the ecosystem as well.
This self-certified infallible message has been brought to you as a Public Service Announcement of the NYAN Public Relations Council, a transparent front organization of notoriously lovable philanthropist and major NYAN hodler coinaday.

MINEDBLOCK: An advanced technological mining platform

With the emergence of all new mining platforms , the energy consumption of digital currencies gets value.
An energy organization based in the Iceland found that the energy measurements used for cryptocurrency mining in 2017 exceed annual energy and energy consumption somewhere in 200 countries. In addition, international energy and energy consumption to win the battlefield exceeds the energy consumption of some developed and developing countries.
The question faced by miners is not just a joke about the extent to which mining checks are affected. Systems like Bitcoin, Litecoin, and Dash become increasingly concentrated. The ability to manage this system is in the hands of several modern mining tasks that consume energy. To claim that the only excavator must depend on the extraction vessel. This mine contributes to centralized organizations.
At present, the mining process ends with a problem that is even greater than the response.
In the early years, the creation of digital currencies became more productive because costs had reached new highs. The rapid expansion of mines in the world led to the introduction of several new chips. MinedBlock will establish a special mining office that focuses on procuring lots of coins from the top 50 markets to ensure that customers can benefit from various revenues.
Through the planned large-scale activities, Minedblock will help improve the decentralization of coins, where there is a large pool so far that dominates the prevailing currency. MinedBlock will also move towards the decentralization dimension within its own organization by disseminating global mining information globally
MinedBlock Limited is responsible for maintaining, replacing, and increasing physical resources and will be responsible for all costs arising from past revenues in the unlikely event that the administration becomes bankrupt. In this case, the symbol owner does not need to cover all misfortune.
One of the most important standards of MinedBlock provides clarity to customers. Minedblock will be fully open to its agreement, ongoing progress and income.
All cost and income data are distributed monthly to be investigated by all symbol owners to ensure full alignment of all supervised mining management.
Each portfolio tends to be claimed by the organization and distributed to speculative committees to provide a complete picture. Mining exercises are constantly monitored and exchanged between coins because difficulties and successes vary. The main goal is to treat one by one the most extreme abilities.
Minedblock will support the use of a dual-token model, which includes benefits and security. With security tokens, users can earn passive income, while utility tags allow users to pay for various services on the platform.

ShionCoin Console Basics

The following is a brief overview of the commands provided by the "shc" utility console program.
The utility program "shc" communication with the server (shcoind) are restricted to the local host that the service is running. You must use the stratum API in order to access the server from a remote machine.
A sub-set of all the commands are provided here. This guide attempts to concentrate on commonly used commands that are useful. Run "shc help" for a full list of commands. Run "shc help " for details about running that particular command.
You can enter an interactive mode by running "shc --prompt".
Run the daemon with "shcoind --debug" in order to print additional information to the log file (on linux, "/valib/share/shcoind.log") for diagnostic purposes.
ShionCoin "pub-key" coin addresses typically starts with "S" or "R". A "script address" will start with "1" and a seg-wit address will start with "3". Coin addresses are verified when entered on the command-line in order to ensure that the address is prudent in respect to the coin interface.
All fees for extended transactions, such as creating context and aliases, are either stored (for update purposes) in a local extended account and/or are provided as mining fees. You can use the "wallet.donate" command to intentionally create a transaction which includes a specified mining reward value.

Wallet Commands

The wallet commands provides capabilities to transfer funds and manage accounts. Each account can contain several coin addresses and has a counter-part "extended account" that is not visible.
Wallet Info: wallet.info
Display statistical and runtime information on wallet operations.
shc wallet.info { "version": 3010000, "walletversion": 60000, "balance": 658, "keypoololdest": 1517000561, "keypoolsize": 101 }
Create Coin Address: wallet.new
The "wallet.new" command is used to create a normal (non seg-wit) coin address and associate it with an account name. Coin addresses may be automatically generated for accounts, for example in order to return "change" in a fund transfer transaction. All change is directly returned to the associated account.
shc wallet.new test S2fzfzf1SStvaMzjGpCtYKxY3t8PXus9Ci
List Accounts: wallet.list
The "wallet.list" command provides a balance of all accounts in the coin wallet.
shc wallet.list { "": 0, "bank": 658, "system": 0 }
Three accounts are created by default. The "" account receives coinbase rewards which are then distributed to users based on their stratum stats. The "bank" account is a 0.1% cut of the rewards received from the stratum mining pool. The "system" account is currently reserved for a cpu-miner which attempts a single mining operation each time new task work is assigned to miners. The frequency of how often this occurs is based on tracking the "luck" of past attempts.
List Coin Addresses: wallet.listaddr
The "wallet.listaddr" command will list all of the coin addresses associated with an account.
shc wallet.listaddr test ["S2fzfzf1SStvaMzjGpCtYKxY3t8PXus9Ci"]
Create Transaction: wallet.send
The "wallet.send" command is the primary method of sending funds.
All ShionCoin transactions are sent with at least the 0.0001 SHC minimum fee. Providing the minimum fee is provided, any fee can is permitted and affects the priority of the transaction.
shc wallet.send bank S2fzfzf1SStvaMzjGpCtYKxY3t8PXus9Ci 10 307711dace8c0583b744af8acd1df2073e36b0c7a54b8830a15ae146f8c22ddb
Test Create Transaction: wallet.tsend
You can "test send" a transaction in order to determine the aproximate fee and size that would result.
shc wallet.tsend bank SLbnKamvSx8FhaBNpHUwffFDLZ16J8phdX 10 { "amount": 10, "tx-amount": 98.999900, "size": 300, "virt-size": 226, "fee": 0.000100, "inputs": 1, "priority": 1085539000000 }
Create Batch Transaction(s): wallet.bsend
The "wallet.bsend" command allows you to transfer funds that are more complicated than would be permitted in a single transaction. Multiple transactions will be created, as neccessary, in order to send the specified coin value. The total value commited to be sent may be lower than the value requested under certain circumstances.
Create Certified Transaction: wallet.csend
The "wallet.csend" associated a pre-created certificate with the coin transfer. The certificate may be used to associate with the certificate, or provide a method to identity the source of the funds.
shc wallet.csend bank SLbnKamvSx8FhaBNpHUwffFDLZ16J8phdX 10
Create Stamp Transaction: wallet.stamp
The "wallet.stamp" command allows you to create a short message (up to 135 characters), or reference a geodetic location, to associate with a local coin address. The stamp transaction is the exclusive method of claiming spring matix location coins. Creating a stamp in the format "geo:," will result in a single SHC coin, once processed on the network, being rewarded for all locations not yet discovered in the spring matrix. A minimum transaction fee (0.0001) is applied for each stamp transaction created.
Use the "ctx.findloc" command in order to search for locations active in the sprint matrix.
Validate Address: wallet.donate
Donated coins are added to the upcoming block reward. Donations may be optionally associated with a certificate. The maximum donation value in a single transaction is 500 coins. Donations are associated with the coin address that generates them, and may contain a geodetic stamp depending on configuration and availability.
The total cost will include the donation coin value specified plus a minimum transaction fee (0.0001 SHC).

Validate Address: wallet.validate
The "wallet.validate" command returns general information about the coin address specified, including whether the coin address is contained in the local wallet.
shc wallet.validate SLbnKamvSx8FhaBNpHUwffFDLZ16J8phdX { "isvalid": true, "address": "SLbnKamvSx8FhaBNpHUwffFDLZ16J8phdX", "ismine": true, "account": "system" }

Create String Context: ctx.findloc
Search for a location by it's name or with geodetic cordinates.
The "ctx.findloc" will scan an area and attempt to find a location within it. This area includes a span of about 100 sq. miles. The closest location with the smallest precision found will be returned. In addition, geodetic information provided by the share library is also utilized.
shc ctx.findloc "geo:46.9,114.2" { "name": "missoula, mt", "summary": "Montana", "zone": "America/Denver", "code": "MUNI", "country": "US", "geo": "46.94000,114.04000", "type": "Municipal Zone", "springable": "false" } shc ctx.findloc "Missoula, MT" { "name": "missoula, mt", "summary": "Montana", "zone": "America/Denver", "code": "MUNI", "country": "US", "geo": "46.94000,114.04000", "type": "Municipal Zone", "springable": "false" }
Note: The "springable" value denotes whether the geodetic location can be claimed in the SHC spring matrix (see "wallet.stamp").
Create String Context: ctx.getloc
Print detailed information about a particular location by it's name or geodetic cordinates.
The "ctx.getloc" command requires specific cordinates to be specified when a latitude and longitude is specified.
ctx.getloc "Missoula Creek" ctx.getloc geo:46.9846,114.1213
Note: The "springable" value denotes whether the geodetic location can be claimed in the SHC spring matrix (see "wallet.stamp").
Create String Context: ctx.setstr
Create a text format context value. This establishes a simple name=value relationship.
Context names are stored as hash keys. Therefore, the string name of the context key must be known before-hand in order to perform the lookup. A small label is also provided as part of the context record which includes a snippet (or all of) the context name.
Context records are signed against the coin address that paid to generate the transaction. Context transaction typically cost about 25 SHC or less to create. A context will expire two years after the date at which it is either created or updated. The owner can update a context by creating a new one with the same name as a pre-existing one. The "context hash" that identifies a context is also the key hash of it's label. The context is shown as part of the transaction details.
shc ctx.setstr test "test name" "test value" { "version": 3, "label": "ab5b128ce3674f81f0271efbbbb191fed56e9a80 test name (1zgfTHd5BQA)", "expire": "Mar 23 08:28:39 2020", "flags": 10244, "signature": "e0539d3ecb54c5c0a29ccd69f0b03dfdfb58bc24", "hash": "ab5b128ce3674f81f0271efbbbb191fed56e9a80", "valuesize": 10, "valuecrc": "1zgfTHd5BQA", "tx": "0dbf21191091e33ad7be3b1ce1983ffffdbedeb804e3ce934021f0fad038d50e" }
Create Geodetic Context: ctx.setloc
The "ctx.setloc" command creates contextual information about a specific place.
The command includes information about a location zipcode, name, and description. In addition, an optional place type code, country code, and web-url can be specified.
The place type corrosponds to one of the codes returned from the "ctx.loctypes" command.
This command has two different modes. One corrosponds to giving a name to a particular geodetic latitude and longitude corindate, and the other includes providing details about that particular location. A single location (as specified by latitude and longitude) may have multiple names, but it limited to a single set of details. Although some common places may be reserved from use (such as common city names), the application of detailed information to a geodetic location comes on a first-come-first-serve basis. Note that context information expires after two years.
The size of the area being referenced is dependent on the place type specified. For example, "AREA" spans roughly 30 sq. miles, while "SPOT" only spans 8 sq. feet. This precision is used in relation to geodetic lookups performed.
shc ctx.setloc test geo:46.9846,114.1213 "Bitterroot Creek" STM US shc ctx.setloc test "Missoula Creek" geo:46.9846,114.1213
Create Identity Context: ctx.setid
Create a binary context from the raw command-line argument specified.
Create Binary Context (raw): ctx.setbin
Create a binary context from the raw command-line argument specified.
Create Binary Context (file): ctx.setfile
Create a binary context from the absolute path specified.
Print Location Types: ctx.loctypes
Print out all suported location type codes for use with the "ctx.setloc" command.
[{ "name": "AREA", "desc": "General Area", "prec": 1 }, { "name": "MT", "desc": "Mountain", "prec": 1 }, .. }

Address Alias Commands

Alias Info: alias.info
Print the current fee to create an alias transaction and the total number of alias records in the system.
shc alias.info { "fee": 31.250000, "total": 1 }
Create Address Alias: alias.pubaddr
Create a persistent public association with a name and a coin address. Once confirmed, the coin address can be referenced as "@" in command-line operations.
When a coin address is specified the alias label will be published onto the block chain in reference. If the alias label already exists, then a transfer will occur providing you are the original owner.
A coin address will be automatically created if none is specified. Only "pub-key" coin addresses are currently supported. An alias will expire after 12 years.
An alias cost around 30 SHC to create and will decrease over time.
shc alias.pubaddr test S2fzfzf1SStvaMzjGpCtYKxY3t8PXus9Ci { .. "alias": { "version": 1, "label": "test", "expire": "Mar 21 09:37:40 2030", "type": 30, "addr": "S2fzfzf1SStvaMzjGpCtYKxY3t8PXus9Ci", "type-name": "pubkey" } }
shc wallet.send bank @test 2 d438fea502b7113f155617fc1b400161bb3045645094df5423ce7e484fadf7f2

Certificate Commands

Certificate Info: cert.info
Prints the current certificate transaction fee and the total number of certificates created on the block-chain.
shc cert.info { "fee": 14.750000, "total": 1 }
Certificate Info: cert.list
Search for a certificate given the provided keyword.
shc cert.list test { "test certificate": "8069f1bbfb435cfa1efdb454684446528343b809" }
Certificate Info: cert.new
The "cert.new" command is used to create a new certificate on the block-chain. The certificate than may be used to derive other certificates or dispense licences. The certificate may have an optional fee specified that will be required to derive or license it.
A certificate can either be designated for issueing other certificates or granting licenses, but not both. Either form of the certificate may be used in order to donate or send a certified coin transfer.
A certificate is signed against a private key that is generated from the associated extended account coin address. You may optionally specify a hexadecimal seed to use for generating the private key. The certificate's private key is not stored in a database or a transaction, and requires the original coin address to be present in the local wallet to be determined. The public key is provided as part of the certificate transaction, and can be used in order to verify the integrity of the associated signature.
The average fee for registering a new certificate is initially about 15 SHC and will decrease over time. The details of the certificate are visible in the underlying transaction that it was generated in.
The frame-work of the certificate is designed to be compatible with the x509 format. See the "shcert" share library utility program for more information on exporting x509 certificate created on the ShionCoin block-chain. Certificates may also be used to provide licensing authentication to run or provide features to programs using the share library "esig" functionality (see the "shesig_verify()" function).
Note that the certificate may contain identifying information such as the originating coin address and, when available, the geodetic location.
shc cert.new test "test certificate" { "version": 1, "flag": 17, "txid": "18d0a73c96af3dd211f27e4ada898e13b4cf25223da2591289edb8a1e86f1129", ..

Certificate Info: cert.derive
Derive a certificate from another certificate. You can optionally specify a fee to be associated with the new certificate, and a fee may be required if one is associated with the parent certificate.
Certificate Info: cert.license
Generate a license from a certificate. A license represents authorization to use a particular product and typically requires a fee to be paid. You can optionally specify a hexadecimal seed to be used when creating the certificate's private key.
Certificate Info: cert.export
Exports the private key information from the extended account that is used to claim ownership over a particular certificate.
Ownership and management of a certificate depends on having specific coin address key(s) in the coin wallet. Exporting a certificate provides JSON formatted content which can be used with "wallet.import" command to attain ownership of a certificate.

Getting rid of mining pools

I feel like mining pools are a bad thing for Bitcoin. Even the most distributed hashing power can be concentrated to dangerous levels, where 1 CPU no longer equals 1 vote, but equals one vote for a chosen representative. Due to how PoW works, small individual miners do not stand a chance of ever getting rewards doing it alone.

I was thinking, what if each miner could work on the latest block at a difficulty that was some fraction of the total network difficulty and incorporating their bitcoin address with the nonce. When they solve a suitable sized hash, they submit this to the network as a transaction. It would be a consensus rule that anyone can use one or many of these "PoW transactions" to incorporate into a newly mined block to reduce the required difficulty for mining that block, as long as they pay those miners their share of the coinbase reward to the listed address.

Anyway, that's just what I was pondering last night. Do other people feel the same negativity towards pooled mining, if so what other ideas have been proposed to try and combat them?

Charlie Lee's (aka coblee) final thoughts on Merged Mining

I'm glad to see that my post has got the community talking. This is what I wanted to do. Sorry for trying to scare you guys into action. Most shibes do not realize how bad the situation is and will become.
I was around when Namecoin went through the rollercoaster difficulty problem and had to merged mine in 2011. I've mined Namecoin and I have also mined Namecoin merged mined with Bitcoin. I created Litecoin and spent 3 years working on it seeing it go from a CPU coin to a GPU coin and now a ASIC coin. I've seen many coins get attacked for lulz. So there are only a few people that truly understands the situation you are in as well as I do. Most of them are happy to sit back and make popcorn. But, I felt responsible for doing something (anything) to try to help. The first time I approached you guys, I thought it was win/win for Dogecoin and Litecoin. Today, it's pretty much only to help Dogecoin survive. I own some Doge, not a trivial amount but also not a huge amount. So I won't lose sleep over it if it goes to 0, but I am definitely not doing this to protect my investment. And I don't make posts to try to manipulate the market.
You may not have liked the way I presented the facts in my post. Some think it's FUD. Maybe I did do a little of that to scare people to action. But whatever the case, at least it's working. Some of you hate me. Some of you think that I'm an egotistical maniac that just came here to gloat and say I told you so. Whatever. I'm too thick-skinned to let this bother me. I do what I feel is right. All I know is that I will hate to live with the fact that I knowingly let dogecoin get attacked when I could have done something about it. Maybe it's because if Litecoin is my child, Dogecoin is my grandchild (or is it my child's dog?) The community and good will you have built in such a short time is admirable. I would hate to see it get destroyed by someone doing it for lulz. And if Dogecoin does get attacked, it will be bad for all of crypto-currency. Dogecoin introduced a lot of new people to crypto-currency. These people will be hurt the most. And that's bad for everyone.
I still see a lot of confusion about merged mining, and I would like to clarify as much as I can:
And if you have questions about how merged mining works, please read my whole merged mining AMA again. It answers all your questions about why merged mining does not hurt dogecoin price. And why merged mining is really the best solution to this unique problem.
I will be around to answer any questions. (But please read the AMA first) And I am at the Chicago Bitcoin conference today and will be at CoinCongress in San Francisco on Wednesday/Thursday. If anyone wants to approach me to talk in person, I will be glad to. I don't bite... really, I don't. :)
*EDIT: I tipped the top posts each 1000 doge until I ran out of coins. I got most of these coins as thanks when I did the AMA. Figure I should pass these back to people who are contributing to this conversation. Thanks! *

Overview of Major Risks of Buying Nyancoins - Version 4

This is the fourth version of the NYAN risks document (based on v3 (v2 and original). These are obsoleted periodically as the old ones get archived to allow for comments again via a new post, to re-examine the risks in light of changes, and for greater visibility.
The purpose of these documents is to provide a best-effort discussion of major risk factors in gambling on NYAN, modeled on the risks disclosure in a 10k (annual report) which is mandated for publicly traded companies in the United States. This document is provided with no guarantee that major risk factors have not been missed, and it is important to recognize my (coinaday) personal bias from holding about one-third of the total supply of NYAN.
Please comment on any risks which are not mentioned here or additional aspects of risks here you think should be further emphasized or any other possible disclosure you think would be helpful to a person considering gambling on NYAN.
Executive summary
Nyancoins have no core developer at the moment, uncertain demand, are traded actively on only one exchange, have had inconsistent blocks, are very vulnerable to 51% attacks, have the potential for serious bugs, an uncertain legal situation, concentrated ownership, depend upon the Internet, may be addictive, and could make you wealthy, which has been alleged to lead to more problems.
Introduction: This is my best attempt to collect every major risk factor from buying Nyancoins, although I can offer no warranty of fitness for this information for any purposes. I believe in honesty and forthrightness. Having this available and obvious is a simple matter of basic decency. Much, hopefully all, of this information has been discussed previously in /nyancoins, but this document in particular is about being up-to-date and central. This page will be updated clearly as appropriate if situations change on a best-effort basis (which may mean updates do not happen for months at times, unfortunately; please ping for faster updates).
If you believe that I am missing something, please note any other major risks you see in the comments.
Core developer: Although we have good general tech support in this community and have put up supporting infrastructure, there is not anyone officially currently working on core client code. This is a significant problem for the long-term, although we are not in any immediate known need of changes.
Demand: NYAN was introduced in 2014 and during the second half of that year had so little demand that it almost died out. In January 2015 I got involved in the coin and for most of 2015 and 2016 I was the majority of the buying pressure. I base these statements on my recollection of the trading history so far and the fact that I have acquired more than 120 million coins, somewhere around 41% of the coins (latest hodling report, June 2017), as well as my observations that I had usually had the leading major bid, and usually the leading bid regardless of size.
In 2017, I have generally not been a major factor in the demand, as I haven’t had money to spare to gamble on NYAN. In June 2017, we have had a spike in buying from an unknown source.
It is unknown whether significant demand for NYAN will continue. Because its value is purely speculative, it is entirely possible that demand for NYAN could simply end. This is a fundamental risk in gambling on NYAN; it is entirely possible that its value will go to zero and not recover.
Exchanges:
Cryptopia is currently the only exchange for Nyancoins with significant volume. If Cryptopia were to fail somehow, it is likely that this would have significant consequences for Nyancoins.
However, there are decentralized exchange technologies, notably CATE, which NYAN2 (my term for the current release, otherwise known as v1.3) should be able to support. On-Reddit exchanges are also possible with tipbots, but require trust as they are not atomic. It should be possible to build an "exchangebot" similarly, although I'm not currently aware of one, but my concept would still have the bot as a trusted central party.
Atomic cross-chain transactions seem to me like a very promising core technology ultimately for building exchanges which can be more proveably secure. They could also allow exchanges to share a common listing protocol as well without having to trust the other exchanges (at least, beyond the core protocol development and maintenance; tanstaafl).
Inconsistent blocks:
Although NYAN is designed to produce a block every minute, there have been times where there has been more than 24 hours between blocks. This results because of an imperfect difficulty function and low base hashing, along with price fluctuations, which can combine to have a low difficulty making the coin attractive for a flood of hashing power which can lead the difficulty function to overcompensate, leaving it stuck with a high difficulty no longer profitable to mine.
I haven’t observed this lately, that is, I don’t recall incidents of this in 2017, but I’ve been paying far less attention to it as well. It is entirely possible for this to recur, as the difficulty function is not fixed (it would require a hard fork to fix it). We seem to have more baseline hashing which helps to avoid this, but it is possible for us to lose that.
A workaround is to use large transaction fees (I've set my client to 337 NYAN) which is enough to cause pools to generally solve a block even if the chain were otherwise stuck. A solution should be included in a hard fork client, but it is unknown when if ever this would be done.
51% attack: Because of the generally quite low hashing power on NYAN, it is highly vulnerable to a 51% attack. Either a leading pool or a new one could choose to do a denial-of-service attack, whether for extortion, lulz, or some other reason (like coinaday being annoying). Such an attack is capable of preventing any transaction processing for as long as it is sustained. I consider this a relatively low risk since I expect we would simply wait it out (and potentially not even notice such an attack for quite a while given the low volume of transactions currently), but it is definitely a potential vulnerability.
Bugs: It is possible that there are bugs in the underlying code. I have never read through all of the bitcoin or nyancoin code, of any version, nor even studied the original bitcoin whitepaper in depth (by the way, we oughta make up a nyancoin whitepaper or ten someday), meaning I have no professional or technical knowledge about whether or not the system is fundamentally sound. I've been going based on "it seems to be working, so it's probably fine", which is, shall we say, more of an engineering than scientific approach.
I have heard reference to a "time warp" bug vulnerability in the KGW difficulty function which Nyancoins has. I do not know details and my understanding is a fix to this would require a fork to change the difficulty function, so I do not anticipate a fix before NYAN3, the term for an eventual hard fork, but it is unknown when if ever this would be done. I consider this vulnerability to be likely to be related to the fundamental weakness to difficulty spikes after large amounts of hashing jumps on the network. Hostile (or simply passing interest with large capacity) hashing does degrade the performance of the network. As a workaround, this class of attack can be mitigated with a transaction to 'unstick' the chain after, since the difficulty function will adjust in the next block after enough wall-time has passed since the last block (so only need one high difficulty solve which can be triggered by a transaction fee).
Legal: Bitcoin faces uncertain legal situations in almost every country. Nyancoin is even more uncertain, as people tend to consider bitcoin and not address impacts on altcoins. Between the potential tax implications and banking regulations and currency laws, there are a wide variety of ways a person could make a felony-level mistake. This can be somewhat mitigated by merely buying and holding, as you won't be responsible for KYC/AML presumably (although arguably an argument could be made in your purchase), and presumably unrealized capital gains wouldn't be taxable (but I am neither a lawyer nor accountant nor any sort of expert on the relevant accounting laws in any country).
Somehow getting legal opinions for Nyancoins in every country would be very useful in my opinion. If Bitcoin and altcoins are well-studied in a given country it should be relatively easy to adapt those opinions and research to Nyancoins, but it would still require some pro bono work in any case. So...hopefully we'll get some lawyer Nekonauts someday who are willing to semi-officially give us an opinion. In the meantime...hope that common sense can save you. If you sell Nyancoins directly, you're going to need to comply with the KYC/AML types of laws of your country. If you're going to do banking operations...may the central bank have mercy on your soul.
I think the best advantage we have is the same bitcoin had for its first years: we're too small for anyone to care. But since we plan to grow significantly, we need to be aware of our legal issues upon scale. Which is to say, whether or not you're allowed to sell 10,000 NYAN to your friend probably has a lot to do with whether your friend legally acquired whatever is being offered in exchange, and whether the value of what you get in return is above a certain level or not. I'm not going to try guessing that level precisely because I know I'll be wrong. $1 is probably fine. $10,000 is probably illegal without some significant licensing. I would suggest either not touching fiat or else deliberately capping it without verification after getting an independent local expert legal opinion.
concentration: The fact that I hold about 41%(? not sure the exact percentage as of Dec 2017 ; need to do updated survey to check; 41% sounds slightly high to me but I'll see...I'll try to update by the end of the year or shortly after) of the currently outstanding NYAN could be a major risk factor, particularly if I do not act in the best long-term interests of the strength of Nyancoins. For instance, I could pull my bids, sell only a small part of my holdings, crash the market, and potentially buy a lot of volume for a lower price. While I cannot foresee any circumstance under which I would do this, it is certainly conceivable that I could be financially, legally, or morally obligated to do so if I were to become insolvent.
Internet outage: if the Internet goes down, we hit a very nasty scenario. We can't process transactions, and all the miners go into a race to make 'useless' blocks on their own. If the Internet were never to come back up, Nyancoins would be dead. If there is a daylong internet outage, the longest blockchain discovered after, presumably representing the most hashing power dedicated to empty blocks during that outage, will win. So I suppose the block rewards in that case are for having the faith in Nyancoins to keep hashing and storing the blockchain during the day without the Internet.
addictive: This was a curiosity to me when I started. Now it's an obsession for me. I'm constantly thinking about how I can help to smooth the path for Nyancoins to grow stronger and better and more valuable. You may find that once you start to realize the impact you can have upon Nyancoins, and that Nyancoins can have upon you, that you start to become addicted as well. It is possible to substitute another addiction in its place, such as dogecoins or pcp, but it is not recommended.
Nyancoin addictions are considered 'mostly harmless'. The exception is if you go 'full coinaday' and start to accumulate more than 10% of your assets in Nyancoins. In this, this is essentially a variety of gambling addiction. I would argue that it beats roulette because you can tilt the odds in your favor, but then, I would argue that, wouldn't I?
mo' nyan mo' problems: Some people have claimed that more money leads to more problems. Since nyan is money, it follows as a consequence of the conjecture. Should this be the case, your increasing nyan could potentially lead to such problems in the future as: enhanced attention from revenue collection services of all kinds (governmental and private), swarms of fake friends and gold-diggers, excessive risk-taking as a result of feelings of invincibility, an increase in certain varieties of targeted marketing, possible disqualification for asset-based welfare for you (or even your children, for instance college financial assistance), an inability to remember how many houses you own, or other serious problems.
Conclusion
There are a variety of different risks in buying Nyancoins. I believe the most serious one is the developer issue. If those of us who have found or come back to NYAN abandon it, it could die. Otherwise, I consider the risks generally manageable, but exchange failure or a currently unknown bug could do serious damage to the ecosystem as well.
This self-certified infallible message has been brought to you as a Public Service Announcement of the NYAN Public Relations Council, a transparent front organization of notoriously lovable philanthropist and major NYAN hodler coinaday.
