Ethereum Classic

Ethereum Classic is an open, decentralized, and permissionless public blockchain, that aims to fulfill the original promise of Ethereum, as a platform where smart contracts are free from third-party interference. ETC prioritizes trust-minimization, network security, and integrity. All network upgrades are non-contentious with the aim to fix critical issues or to add value with newly proposed features; never to create new tokens, or to bail out flawed smart contracts and their interest groups.

Funding the future with the future of currency

**About the Einsteinium Foundation** The Einsteinium Foundation was created to help, in any small way it can, raise funding for cutting edge scientific research. To this aim we created Einsteinium, a new crypto currency (similar to Bitcoin), to gather funds that can be distributed to projects the community chooses. Combined with donations from the community at large we will help fund some of the most innovative projects currently under-way or help seed those waiting to start.

Our first generation hardware wallets were made of military-grade aerospace aluminum. We’ve stripped all that down to just focus on air-gapping your private keys.

Hey bitcoin! I'm Lixin, longtime bitcoiner and creator of Cobo Vault.
I come from a background in the electronic hardware industry, and experienced one of my products being featured in Apple Stores around the world. Back in 2018 Cobo CEO Discus Fish, who also co-founded F2Pool, invited me to help build Cobo’s hardware product line. As we had strong ties to miners in China, we naturally designed the 1st gen with them in mind. In China, mining farms are nearly always built in very isolated places where there is very cheap wind or water electricity. When we built our 1st generation Cobo Vault hardware wallet, we needed to maximize the durability of the device in addition to its security. We used aerospace aluminum rather than plastic and made it completely IP68 waterproof, IK9 drop resistant, and military standard MIL-STD-810G durable for the mining industry.
Things changed last year when I went to Bitcoin 2019 and talked to lots of hodlers in the States. I found that 95% of them don’t care about durability. I asked them if they were afraid of their home being flooded or burned down in a fire. The answer is - yes, they are afraid of these things, but see them as very low possibilities. Even if something were to happen, they said they would just buy another HW wallet for 100 dollars. From these conversations, it became more and more clear we should design a product around a normal hodler’s needs.
Our 2nd gen product compromises on durability but doesn’t compromise on security.
Most hodlers share some needs with miners:
  1. Hodlers want a more air-gapped solution so we kept QR code data transmission between your hardware wallet and the companion app which is also auditable.
  2. A Secure Element is the strongest wall of protection from physical attacks. We are the first hardware wallet - also maybe the first electronic product with SE - to have open source SE firmware.
  3. A battery can be a significant weak point. The 2nd gen continues the legacy of detachable batteries to prevent corrosion damage and will also support AAA batteries in case your battery dies someday.
  4. The 2nd gen also keeps the 4-inch touchscreen so you don’t need to suffer from tiny buttons and little screens anymore. Human error is one of the biggest reasons people lose their assets.
  5. We kept other features like the self-destruct mechanism and Web Authentication, which prevent side-channel and supply chain attacks.
If you'd like to read more about these features, check out our blog posts.
Aside from the legacy of the 1st gen, our 2nd gen product will have:
  1. Open source hardware wallet application layer and Secure Element firmware code. With the open source firmware code, you can see: random number generation, master private key generation, key derivation, and the signing process all happen within the SE and your private keys never leave.
  2. At the Bitcoin 2019 conference half the hodlers I met told me they own multiple hardware wallets which they use on the go. We added a fingerprint sensor you can use to authorize transactions without typing in your password. No need to worry about surveillance cameras when using your hardware wallet in airports.
  3. We will also support PSBT (BIP174) to be compatible with third-party wallets like Electrum or Wasabi Wallet in case people have need of using Cobo Vault with their own node or coinjoin. Multisig between Cobo Vault and other wallets will be realized to prevent single point failure with any brand of hardware wallet.
  4. By sacrificing the durability, we successfully controlled the price under 100 USD for the basic version.
  5. BTC-only firmware version for people who want to minimize the codebase for less of an attack surface.
We truly appreciate the support from the community and are giving away free metal storage Cobo Tablets with every purchase of our 2nd gen for a week! Add a tablet to your cart and place your order before May 5th, 8 AM PST to claim your free metal storage. Find us on Twitter CryptoLixin and CoboVault - any suggestions or questions are welcome!

Weekly Crypto News — July, 13 (Bitcoin, Vechain, Visa, Binance, and other)

What important crypto events happened last week?

Regulation, Government, Mass Adoption

📌 Visa has posted a vacancy for blockchain developers. Potential employees will create decentralized applications. Visa requires experience with Ethereum, as well as the ability to work with the Bitcoin, Ripple, R3 blockchains and the Solidity programming language. Employees will be part of a team dedicated to creating innovative “non-card” payment products for Visa.
📌 Binance-backed blockchain hotel reservation service Travala has announced a partnership with Expedia, a US travel agency. Thanks to this, it will be possible to pay for rooms in 700,000 hotels from the company's catalog using Bitcoin.
📌 Bitcoin industry veteran, venture investor and billionaire Brock Pierce announced his intention to compete in the upcoming US presidential election. Pierce noted that he is going to the polls as an independent candidate. The campaign will be held under the slogan “Leadership. Experience. Values ”, but there is currently no specific program that Pierce intends to offer voters.
📌 Zap and Visa will release a payment card for Bitcoin payments. Jack Mullers, developer of the popular lightning wallet Zap Wallet, has announced the launch of Strike's open beta. With it, users will be able to make payments in Bitcoin through direct bank transfers.
📌 The Central Bank of Japan announced the start of testing the digital yen. According to the statement, at the first stage of testing, the bank intends to evaluate the possibility of launching the coin from a technical point of view and will consider the reliability of such a tool and its availability to the general public. Meanwhile, China is already in full swing testing digital yuan in 4 cities in such large networks as McDonald’s and Starbucks.
📌 The United States Internal Revenue Service (IRS) has launched an investigative pilot program that seeks to find tools to track various types of cryptocurrency transactions. These include private coin analysis software and second-tier protocols such as the Lightning Network. The tools will be used by investigators, who in their work face the need to unravel the movements of privacy-oriented cryptocurrency users.

Coins, Projects, Startups

📌 VeChain rose 73% amid a conference with Microsoft and Amazon. The market value of cryptocurrency has grown by 73% over the past five days, updating a two-year high. Thanks to this, the coin returned to the top 20 digital currencies by capitalization.
📌 Binance has announced the distribution of BinanceTurns3 collectible tokens, released in honor of the platform’s third birthday. BinanceTurns3 are non-fungible (NFT) tokens with unique properties. NFT has no practical use, but they can be bought and sold at auctions. The cost of previous Binance NFTs reaches several thousand dollars. The most expensive token was sold at the OpenSea marketplace for $5,000.
📌 The developers of the Ravencoin cryptocurrency recommended that miners activate an emergency update after a vulnerability was found. The bug resulted in excessive emission by Raven Coin attackers in excess of the established block reward of 5,000 RVN (~$91). User assets were not affected.

Blockchain, Mining

📌 Sino Global Capital CEO Matthew Graham announced the sale of Filecoin mining equipment (FIL) in China, which surprised the expert. In the Filecoin system, miners receive a reward for storing information, so Graham doubted the need for special equipment. The main network of the project has not yet been launched. Thomas Heller, F2Pool Mining Pool Global Business Director, confirmed that sales are made only in China.
📌 The head of Tesla and SpaceX, Elon Musk, a year later denied speculation about participating in the creation of solutions on Ethereum. In the crypto community, the entrepreneur was thought to participate in projects with ETH. In April 2019, Musk tweeted with the word “Ethereum”. Subsequently, he made a reservation that it was a joke. Elon Mask still considers Bitcoin the most reliable cryptocurrency, although he owns only 0.25 BTC.

The Best Cryptocurrency Mining Pools in 2020

This review is not sponsored! Neither it is an ad.
How to choose a mining pool? How to avoid stale shares? The pros and cons of different services.

What is a cryptocurrency mining pool?

A “mining pool" is a server that distributes the task of calculating the block signature between all connected participants. The contribution of each of them is evaluated using the so-called “shares”, which are potential candidates for receiving a signature. As soon as one of the “shares” hits the target, the pool announces the readiness of the block and distributes the reward.
However, if you participate in the pool, then you will have to share the profit with all the participants in the pool, but for the majority, this usually is the most profitable option.

Which pool is better for mining?

The best mining pools should meet the following criteria:

Key selection criteria

To select a good pool for each specific cryptocurrency, you need to carefully study all the information available about it on its website and on the forums.
To reduce the number of stale shares, it is better to mine on the pool closest to the miner. You can choose the fastest mining pool by studying the information about the processing speed of the share in the mining program or by pinging the time it takes for the signal to pass from the miner's computer to the servers of the pool.

We’ve been working on a new product release for a year and want to hear your opinions on the product. Read on for product information and our vision for hardware wallets.

TL;DR Key features of Cobo Vault 2nd gen we are going to launch:
Hey bitcoin! I'm Lixin, a longtime Bitcoiner and creator of Cobo Vault.
I come from a background in the electronic hardware industry, and experienced one of my products being featured in Apple Stores around the world. Although my interest goes back to 2010, my career intersected Bitcoin when Discus Fish (CEO of Cobo) invited me to help build Cobo’s hardware product line. Discus Fish is also the co-founder and CEO of f2pool, one of the largest mining pools currently in the world, and one of the earliest advocates of bitcoin in China.
Back in 2018 we built our 1st generation Cobo Vault hardware wallet. As we had strong ties to miners in China, we naturally designed the 1st gen with them in mind. For those who are not familiar with the mining industry in China, mining farms are nearly always built in very isolated places where there is very cheap wind or water electricity. As the miners would take their storage into these isolated regions, we needed to maximize the durability of the device in addition to its security. We used aerospace aluminum rather than plastic and made it completely IP68 waterproof. We also gave it a hardshell metal case you can put it in, which is IK9 drop resistant and passes the American military durability test MIL-STD-810G.
As for the electronic components inside the device, in order to maximize security, we made it as air-gapped as possible with QR codes. We see this as an important choice because USB cables and Bluetooth are not transparent and have a bigger attack surface. With QR codes you can see exactly what is going on and do not have to connect to a laptop which could have malware on it. QR code interaction needs a camera and a more complicated system which needs to be supported by high-level chips.
All these come with a cost, and the 1st generation isn’t as accessible for average hodlers. For more details on the product, visit here.
Things changed last year when I went to Bitcoin 2019 and talked to lots of hodlers in the States. I found that 95% of them don’t care about durability. I asked them if they were afraid of their home being flooded or burned down in a fire. The answer is - yes, they are afraid of these things, but see them as very low possibilities. Even if something were to happen, they said they would just buy another HW wallet for 100 dollars. From these conversations, it became more and more clear that the position for miners and hodlers is totally different.
After coming back from that conference, our team began the almost one year journey of designing our 2nd gen product. It compromises on durability but doesn’t compromise on security.
We designed the 2nd gen product all around a normal hodler’s needs.
Obviously hodlers share some common needs with miners:
If you'd like to read more about these features, check out our blog posts here.
Aside from these legacies from the 1st gen, our 2nd gen product will have some other big improvements:
Personally, I am a bitcoin maximalist and also a big fan of the KISS principle. We will also release a BTC-only firmware version for people who want to minimize the codebase for less of an attack surface.
Thank you for reading until here. More details like final price would be released later when we officially release the product in late Apr. Any suggestions or questions are welcome. Also you can find me @CryptoLixin or @CoboVault on Twitter! Ears are widely open!

PSA: F2Pool is mining INVALID blocks

Current status: both F2Pool and Antpool fixed.
BIP66 protocol rule changes have gone active in part thanks to Antpool and F2Pool's support of it - but their pool appears to not actually be enforcing the new rules, and is now mining invalid blocks.
What this means:
SPV nodes and Bitcoin Core prior to 0.10.0 may get false confirmations, possibly >6 blocks long, until this is resolved.
Miners using F2Pool may not get paid (depending on F2Pool's handling of the situation and reserve funds). The pool is not getting 25 BTC per block at this point. Using F2Pool before they resolve this is contributing to SPV/old nodes being compromised, so please use another pool until it is fixed.

I am stepping down as a moderator of r/btc and exiting the bitcoin community and entering the Ethereum community.

I am stepping down as a moderator of btc and exiting the bitcoin community. Thank you all for fighting until the end. I know I am going to get a lot of hate from pretty much everyone for this post, but I felt the need to post it anyway.

Why Give Up?

I think bitcoin is past the point of no return. There are a number of different routes that bitcoin could take this year, and as far as I can see, they all end up at the same destination; failure. I know I am going to get a lot of flack for this post, and I understand that. I have witnessed bitcoin being announced “dead” many many times throughout its history and I absolutely could be wrong, but almost every one of their predictions were based on a lack of understanding of bitcoin. I don’t feel my prediction is has a lack of understanding. If I am wrong, then I feel it will be through sheer luck that bitcoin survives. I was a bitcoin early adopter in 2011 and have invested far more time into bitcoin than is reasonable. I truly hope bitcoin does survive, but what I think will happen is not predicated on what I want to happen.

How might bitcoin fall?

The Past

I am not going to go through everything that has lead us up to this point. Many of your are well aware of what has brought us here. Bitcoin up until the beginning of 2014 was an unparalleled success. For those of you who weren’t around at the time, there was a huge amount of excitement in the community at all times. It felt like every month there was some announcement that had a positive impact on bitcoin. A new major company offering bitcoin payments, a bitcoin company offering a new service, a new piece of software being added to clients to make them more useful. Bitcoin was making continual progress and the community was unified. Compare the situation back then to day. We have now had 2 years of stagnation, and in many cases degradation of the network.

The Present

The network is now slow and expensive (and getting slower and more expensive), companies have been leaving bitcoin at an exponential rate. No new major companies have adopted bitcoin and there are no signs of this changing in the future. The community is irreparably divided and is at war with itself. Development has stalled.
Where bitcoin has stalled, other cryptocurrencies have been making enormous ground. Bitcoin does not exist in a vacuum. It has competition. Other cryptocurrencies already offer significantly more advance features than bitcoin. The only thing bitcoin has left over other cryptocurrencies is it’s network effect. The inertia of network effect is truly enormous. Bitcoin has been coasting on it for 2 years now. Technology develops rapidly though, and many people are always looking for the next big thing. Investors want to make money and developers want to work on the most advance and growing technology. There has been very little investment into new bitcoin specific companies over the past 2 years. The only new bitcoin company I know of that has received significant investment in the past two years is Blockstream. There has been a very large amount of investment into blockchain companies in general though. The money is there, it’s just not going into bitcoin.
Ethereum has now reached close to 1/3 of bitcoin’s market cap and there is no sign that it is going to let up any time soon. The ethereum community is a breath of fresh air compared to the current bitcoin community and it feels very nostalgic there. It feels very much like the bitcoin community did 3-4 years ago. They have showed that they are not afraid of using hard forks to upgrade the protocol. They have a leader who is intelligent, pragmatic and good at communicating and IMO who is likely to get the network through the early volatile years. The community showed that they value pragmatism and reality over ideology when they stopped a theft of a large percentage of the currency supply and did so without having any adverse affects on anyone other than the thief. They also achieved this while under attack from bitcoin. They have been working with major organisations and companies to promote and forward the use of the network and they listen to the users of the network to find out what problems they have and which features they want, and then work towards satisfying the needs of their users. The developers of the network have known large holdings of the currency, which means conflicts of interest are less likely to arise and protocol development can directly correlate increased returns for the developer’s investment.

The Future

There are a number of possibilities, but I believe all end with very similar outcomes.

Scenario 1 - BU/EC gains 75% of the network hash rate

If BU gains 75% of the network hash rate, a hard fork will become likely (although not certain). Core and their supporters will start to try and burn down the network. All communication channels will overflow with FUD (some real, some fake). Core supporters with large bitcoin holdings will start dumping them on the market in ways that will cause the most damage to price. Core will start recommending at the very minimum a difficulty readjustment and quite likely also a POW change. Price will fall extremely far as speculators adjust their risk exposure and wait out the storm, traders will short the market to make as much money as possible during the fall, and core supporters try to get the BTC price to go as low as possible on the BU/EC side of the fork and BU/EC supporters try to get the price to BCC price to go as low as possible. Whatever the price is before the fork is certain, I think it is likely to reach 50% of that between the time a fork becomes certain and when the fork actually happens. After the fork happens the price could go down to literally any level. While this is happening, the Ethereum market cap is going to overtake bitcoin even if the Ethereum price does not increase (which it will). Bitcoin will not survive this. The moment Ethereum overtakes bitcoin as the biggest cryptocurrency, everyone will find out. It will be posted in articles in every technology news website on the internet. Once the casual bitcoin holders/users find out (hint most do not even pay attention to what is going on in bitcoin) they will quickly panic and either sell to fiat, or sell into Ethereum to speculate. Mining will almost instantly become unprofitable at that point. Monumentally unprofitable in fact. The payout of 12.5 per block will not even slightly cover the cost of electricity and because miners have no direct control over the price of bitcoin they will be absolutely powerless to do anything other than mine at a loss for a very long period of time. If bitcoin price drops to $100, which IMO is very conservative, then it is likely that 90% of the miners will have to turn their hardware off. This means that the difficulty adjustment periods will increase by a factor of 10 to 20 weeks. These miners that are left will need to mine at a huge loss for up to 20 weeks, or hope that somehow the price recovers. I don’t think even the biggest miners could survive that. Further difficulty reset hard forks will be proposed and it will be chaos.
While all of this is happening, Ethereum is likely to be running fine and price will likely be rising significantly as money from bitcoin pours into it.

Scenario 2 - BU/EC never gains 75% of the network hash rate

In this scenario there will be absolutely stalemate. Core will not be able to implement Segwit and therefore will not be able to change bitcoin into a settlement network, but also the transaction throughput will not be increased through larger blocks. The debate will have become so vitriolic that no further progress can be made within bitcoin. Bitcoin simply will not scale on OR off-chain. In this scenario the end is not so violent like in scenario 1 but then end result is the same. Ethereum (and other cryptocurrencies in general) will continue to gain market share throughout the year as Bitcoin remains stuck in stalemate. The bitcoin price continues decreasing and the Ethereum price keeps on increasing until Ethereum overtakes bitcoin. Once the flip happens, it will accelerate significantly as people realise what is happening. The end result is the same as the later part of scenario 1.

Scenario 3 - BU/EC lose most/all of the network hash rate

In this scenario Core manages to get Segwit accepted by the network. Most people in btc simply leave bitcoin for good. Fees will remain high and transaction throughput low. Core will not increase the block size limit until after LN has been proven to work and users have been forced/coerced into using it. LN is not anywhere near ready for production and it is likely to take at least 2 more years until it is released and working and another year or two until it is fully implemented into wallets, and then another year until businesses are able to understand and use it in their backend. I.e. in an ideal world where everything works as intended in this theoretical system it will take 4-5 years until bitcoin has similar properties to what it had 2 years ago. This obviously ignores the fact that there has been no analysis on whether this would even work on an economic level, let alone a technological level.
As transaction fees rise users and business will be pushed into using other cryptocurrencies and fiat and at some point bitcoin’s network effect will be overcome by Ethereum’s. This scenario is essentially the same as scenario 3, but there maybe some initial price pump when Segwit activates and people enjoy and end to the debate. This will likely be short lived though.

What is most likely to happen (IMO)

If BU/EC is to continue to gain further market share of the hash rate and reach the 75% requirement that many parties have suggested. It is likely to take at least a couple more months of deliberations. For this to happen, a number of large pools will need to switch over. Bitfury has stated that they will not support BU and are mining Segwit and have even started mining UASF blocks. HaoBTC is still sticking to the HK agreement (which literally no one else is) and will not be running anything other than Core. This means it is really down to F2Pool and some of the smaller Pools. F2Pool has stated that it will stop signalling for classic and there is no indication that it will start signalling for anything other than Core (not segwit), and has stated that he thinks BU is dead.
This suggests that the most likely scenario is scenario 2. BU/EC will not activate, but nor will Segwit. There are some things that may or may not happen in this scenario. For example it seems that Core are willing to do a UASF to push Segwit through under the pretence that any of the miners that are not mining Segwit are illegitimate as they are against the “consensus”. This will force the miners into making some kind of decision either way. Many are likely to side with Core but I think a significant portion will side with BU initially. A number of different things could happen in this scenario depending on the ratio of hash power on each side of the split. If the split is mostly equal, I expect that two coins will survive for some amount of time. What happens with bitcoin from that point I have no idea. If BU/EC gains the most hash power then the debate will rage on as the BU/EC will refuse to attack the minority chain out of moral reasons. What happens with bitcoin from that point I have no idea. If Core gains the majority share then the BU minority chain will be attacked by some of the majority miners. Core and their supporters do not have any moral objections against this kind of attack. The minority BU miners will then switch back to Core and it will likely play out like in scenario 3.

So this is BU’s fault for forcing a hard fork?

No, this is Core’s fault by making a hard fork dangerous by telling everyone a hard fork is dangerous for the past two years and blocking every conceivable compromise. They have petrified the bitcoin community and convinced them that any kind of hard fork for any reason that does not come from them is dangerous. They have done this to hold onto the power they should not even have in the first place. They have become the self appointed kings of bitcoin. They have achieved this by threatening to burn down the network instead of making a compromise, and by attacking anyone who threatens to take this power away from them. Unfortunately, when Gavin stepped down, he handed to keys to the bitcoin house to the wolves and once they are inside, it seems it is not possible to get them out again. The only way to make them totally irrelevant is to exit and let them be kings of nothing.

Why did you even become a mod in the first place?

I have known bitcoin was on a negative trajectory for quite some time but I felt that one last push to save it was worth my effort. I wanted to help btc be the best bitcoin subreddit to overcome some of the damage that bitcoin has done to the community. IMO btc is the best bitcoin subreddit, but it is far from perfect. I feel very strongly that the moderation of btc is a microcosm of the situation in the bitcoin community in general. I feel there is far too much weight put on idealogical decision making rather pragmatism and realism. The moderation policies of btc are ‘hands-off’ to a point I think is actually detrimental to the sub and to bitcoin. The issue is that, trolls overwhelm the sub and cause constant controversy. They act like a fire under the community and purposely rile everyone up. There is a reason for this. bitcoin was controlled mostly through censorship. Censorship alone was enough to create an echo chamber. They do not have control of the btc moderation team (well actually they managed to get two mods on here who have since left/been removed) so they must turn it into an echo-chamber by other means. They have achieved this by making sure every single post has comments from trolls that try to rile up the community. This makes the btc community have more tunnel vision as they/we try to insulate ourselves from the trolls. The problem is that it means that the community becomes highly idealogical and focused on only one goal.
IMO it is a failure of this sub to not remove comments from trolls. This is pretty much a standard policy across the whole of reddit and the only reasons for not employing it are idealogical. Removing trolling is not the same as banning specific ideas or topics being genuinely discussed. Not doing so just makes btc a frustrating place to try and discuss things. It also means that any actual discussions outside the block size debate get very little traction as everyone gets dragged into the angry posts.
I should be clear though, the other mods of this sub are great and absolutely want what is best for bitcoin.

Isn’t this all just FUD

I am not writing this to sway anyone. This is what I genuinely think will happen, but of course I could be wrong about every single prediction. It saddens me enormously to write this. The current trajectory for Bitcoin is down and the the trajectory for Ethereum and other cryptocurrencies is up. There will likely be people who say “but Ethereum doesn’t have any uses cases”, my argument to that is; what use-cases does bitcoin have right now that could not immediately be adopted by Ethereum today? There will also be people who say “but if bitcoin dies then all other cryptocurrencies will die with it, because how could anyone trust their money if it might just disappear”? My argument to that is; all cryptocurrencies are still in their infancy, even bitcoin. The writing has been on the wall for Bitcoin for quite some time. I do think there will likely be one ‘great’ cryptocurrency, but until that cryptocurrency is adopted by the masses, that title is still available. If the title of ‘biggest cryptocurrency’ can be taken then it was likely never meant to have it very long anyway. If/When a cryptocurrency manages to achieve mass adoption then it will have hundreds of millions of people, companies, organisations and even countries defending it. At that point the entire system will be working towards it’s success. At that point, the current moral ambivalence towards attacking a minority chain will be seen as ridiculous. After mass adoption of a cryptocurrency (for example Ethereum) has occurred, grandma’s will be writing to their local MP in support of the cyberwar against the Ethereum competitor ‘Othereum’. That is decentralisation. Huge numbers of diverse entities working to defend it. This will never happen on a network as limited as bitcoin’s is. In fact bitcoin is actively losing allies.

TL/DR

I’m out. Ethereum is likely to take over this year as bitcoin becomes myspace. This may happen very rapidly. I hope I am wrong.

Disclosure:

I hold both Bitcoin and Ethereum. I have held a number of different cryptocurrencies over the years, but my holdings were almost always 90-100% bitcoin until recently.

Small pools that include low fee transactions: thank you

If every bitcoin mining pools simply selected transactions from the mempool only ordered by transaction fees, we will have a situation where every bitcoin users will be trying to out bid each other continuously for the next block - or risk having their transaction dropped from the memool ( most wallets might not detect this and might not re-broadcast ).
Some pools decide to take a small percentage of low fee transactions, then more txns with this fee then finally prioritize high fee txns that want the next block.
Without this a proper fee market cannot develop. Why?
Because not every transaction needs to be confirmed quickly, some transactions just need to confirm eventually...
Low Priority: refilling your LN wallet. As long as the txn confirms eventually without dropping it doesn't matter
High Priority: sending 5K BTC to the exchange to sell
By some pools mining low fee transactions bitcoin users that are doing low priority transactions don't have to bid against people doing high priority transactions so long as their txn eventually confirms.
So far I have refilled my LN wallet - when median fees were 2-3 dollars, using 1 sat/byte fee twice! Both txns were confirmed under an hour...
Thank you:
F2Pool: https://blockchair.com/bitcoin/block/577391
HummerPool: https://blockchair.com/bitcoin/block/577472
for mining my low fee transaction.
If you are a miner please consider supporting a pool that has a progressive fee selection policy.

2019 Crypto News Reviews

2019 Crypto News Reviews

https://preview.redd.it/o62demiyuq741.png?width=1472&format=png&auto=webp&s=7408a7f5efff95013292fdc25379dd642825d10f
As the end of 2019 draws closure, we are looking back at the most influential news items for the blockchain sector.

5–7 January

ETC 51% attack, a nightmare for small altcoins
As a top 20 crypto asset, Ethereum Classic is not seen as an easy target for a 51 percent attack, and yet in early January, its blockchain was successfully hijacked for several days with estimated losses of $1.1 million. This attack has caused many people to panic, as the small PoW consensus coins are vulnerable to 51 attacks. Luckily ETC has not been stunned by the 51 attack, after a short fall in prices, ETC quickly created a new record of the highest price.

16 January

The only not cool thing about Grin coin is its price
Grin, with the “three nada” label-no ICO, no pre-digging, and no investors, was officially launched on 16 January. “Bitcoin 2.0”, “super privacy coins”… the cryptocurrency community was willing to give it all the good crowns. After the launch of its main network, the price of Grin coin has jumped up and down as was expected. Although Grin has experienced some bad luck as the dropout of its core developer Gary, by launching of the Asic mining machine and the Grin foundation receiving 50 bitcoin donations, this unique project is still motivated to move forward.

February

Lightning Network passed the torch all around the world and it is only a beginning
On January 19, 2019, Bitcoinist Hodlonaut began a social experiment dubbed “Lightning Torch” to test the capabilities and UX experience of the Lightning Network. In total, the torch has been a great success. Many people believe that 2019 was the year, when the Lightning Network shined. However, its security and the ease of use were frequently challenged. Not long ago, the Bitfinex exchange announced support for Lightning Network deposits and withdrawals. This is a small step for the exchange but definitely a big step for the Lightning Network.

April

USDT is going to die? Nope, it is still safe and sound
New York’s top cop accused USDT’s issuer of participating in a cover-up to hide the loss of about $850 million in client and corporate funds. People have revived doubts about Tether’s claim that each of its so-called stable coins is backed by $1 of assets — a feature that gives the coins a central role in crypto markets around the world. This has made many investors switch their boats to PAX and TUSD. But up to now, dapptotal data shows that USDT still has about 81% market share.

4 June

Justin stood Warren Buffett out
Justin, Sun Yuchen, officially announced himself the winner of the charity lunch with Warren Buffett, chairman of the holding company Berkshire Hathaway, submitting a record $4.57 million on June, 4. This news has gone viral in China, making Sun a hot topic online. However, because of coming down with kidney stones, Sun decided to postponed this meal, which has made Sun again cover the headlines of the international news media.

18 June

Facebook unveils Libra White Paper
Libra was officially announced by Facebook and 27 global industry giants on June 18, 2019. With such a global attention, Libra has faced strict regulations all around the world and many global central banks have started working on digital currencies, countering Libra.
Over the past six months, after being abandoned by few of its core members of the association, Libra was forced to slow down its pace. However, worth mentioning, because of Libra, blockchain has become the focus of global attention in 2019.

1 July

PlusToken may be driving down the price of Bitcoin
In July, Chinese media reported that the PlusToken scam attracted over 3 billion worth of cryptocurrency. Six individuals connected to PlusToken were arrested in June. The stolen funds have continued to move through wallets and be cashed out through the independent OTC brokers operating mostly on the Huobi platform. It has been speculated that PlusToken sccammers didn’t just steal $2+ billion worth of cryptocurrency. They may also be driving down the price of bitcoin.

5 August

The second halving of Litecoin
Litecoin (LTC) has experienced an event that is designated to happen once in four years: the halving of the block rewards. On Aug. 5, 2019, Litecoin rewards for producing a block were halved from 25 LTC to 12.5 LTC. A co-founder of one of the largest mining pools, F2Pool, stated on Weibo that, given the electricity costs of 0.26 yuan ($0.037) per kilowatt per hour, some mining rigs like L3+ could close their business right away.

23 September

Bakkt isn’t the chosen one, but it is growing to be the one
On September 23, silver-spoon-born Bakkt was officially launched. Specialists believed that it is likely to allow more investors and funds to enter the cryptocurrency industry. However, the platform has faced a great failure and only 72 bitcoins were traded on the first day. In early December, its daily transaction volume has quietly climbed to $ 37 million from only 72 bitcoins. Although the data is still relatively small compared to the top exchanges, being a certified platform by the regulatory body helps a lot. Through the continues development, Bakkt may become the influential platform for the Bitcoin pricing power, which will empower the platform with the super power.

25 October

Xi Jinping Urges Accelerated Blockchain Technology Adoption in China
China’s President Xi Jinping has called for the country to accelerate its adoption of blockchain technologies as a core for innovation. President Xi made the comments at a Politburo Committee session on blockchain technology trends on Oct. 24, stressing that the implementation of integrated blockchain technologies is key in promoting technological innovation and transforming industries. The next day after Politburo meeting, the price of Bitcoin soared 42% to $10,500- hitting the biggest daily gain since 2011.

29 October

Chinese cryptomining giant Bitmain’s civil war breaks into open
On 29 October, the Bitmain co-founder Wu Jihan returned to the company after an absence and replaced Mr Zhan’s name on the company’s registration documents with his own. Mr Wu threatened employees with punishment if they continued to meet or communicate with Mr Zhan or carry out any of his instructions. In the past two months, Wu Jihan offered three tempting and determined mining axes: installment payments, option hedging, and joint mining.

21 November

The call of future-Canaan is listed on NASDAQ
On November 21, Canaan was listed in NASDAQ, commemorating the first share of the blockchain going public. The listing of Canaan was almost the biggest event in the blockchain industry in November. Unfortunately, CAN broke after a short rise of 40%, falling to $4.65 up to now, reaching half of its listed price. However, worth mentioning is that listing of Canaan represents that the traditional financial world has thrown an olive branch on blockchain concept stocks, marking the beginning of the long way to go.

Bitcoin Cash: A Reflection on How Far We’ve Come

On August 1, Bitcoin resumed its original roadmap, scaling on-chain towards global adoption as Peer-to-Peer Electronic Cash.
It’s been just 3 and a half months since Bitcoin Cash broke away from BTC in order avoid a software mutation called Segwit, and to restore progress and growth to the ecosystem.
After a recent price rally that saw us reach 0.5 BTC ($3000), the reality is setting in that an overnight ‘flippening’ scenario that some people hoped for is unlikely, and that we have a longer road ahead.
It’s really important to remember how much has been achieved in such a short time.
Let’s take a moment to reflect on how far we’ve come as a young community.
July:
August:
September:
October:
November:
This rate and scale of industry adoption is unprecedented.
With every BTC holder receiving an equal amount of Bitcoin Cash, and with the price over $1300, the rate and scale of user adoption is unprecedented.
With fast, reliable transactions and fees that are less than 1 cent, and with both BitPay & Coinbase hinting at a full Bitcoin Cash integration, the rate and scale of merchant adoption will be unprecedented.
With unprecedented industry, user and merchant adoption, it’s only a matter of time until Bitcoin Cash becomes the default medium of exchange and store of value cryptocurrency.
The old Bitcoin is back. You can feel it. It’s the resurgence of a grassroots movement not seen for years. People are putting Bitcoin Cash posters in the streets, handing out leaflets, tipping strangers a few dollars online, and asking in forums how they can contribute to the community.
Just in the last couple of days a ‘Bitcoin Cash Fund’ was established, to assist with marketing and projects. The initial goal was $200 to make a short animated advert, but over $17,000 has been donated already. All of this positivity and energy is inspiring.
While businesses are being forced to abandon BTC due to exorbitant and skyrocketing fees (upwards of $10), they’re being cheered on every day as they embrace Bitcoin Cash.
The original vision is still alive. As an early bitcoiner, I’ve never been more optimistic.
Make sure you involve yourself in the community, we’re just getting started :)

Decred Journal – July 2018

Note: you can read this on Medium, GitHub or old Reddit to view all the links

Development

dcrd: Several steps towards multipeer downloads completed: an optimization to use in-memory block index and a new 1337 chain view. Maintenance: improved test coverage, upgrading dependency management system and preparing for the upcoming Go 1.11 release.
dcrwallet: A big change introducing optional privacy-preserving SPV sync mode was merged. In this mode dcrwallet does not download the full blockchain but only gets the "filters", uses them to determine which blocks it needs and fetches them from random nodes on the network. This has on-disk footprint of 300-400 MB and sync time of minutes, compared to ~3.4 GB and sync time of hours for full sync (these are rough estimates).
jy-p: the server side of SPV (in dcrd) was deployed in v1.2.0, the client side of SPV (in dcrwallet) is in our next release, v1.3.0. Still some minor bugs in SPV that are being worked out. There will be an update to add the latest features from BIP 157/158 in the next few months. SPV will be optional in v1.3.0, but it will become the default after we get a proper header commitment for it (#general)
Decrediton: besides regular bugfixes and design improvements, several components are being developed in parallel like SPV mode, Politeia integration and Trezor support.
Politeia: testing started on mainnet, thanks to everyone who is participating. A lot of testing, bugfixing and polishing is happening in preparation for full mainnet launch. There are also a few missing features to be added before launch, e.g. capacity to edit a proposal and versioning for that, discussion to remain open once voting starts. Decrediton integration is moving forward, check out this video for a demo and this meta issue for the full checklist.
Trezor: Decrediton integration of initial Trezor support is in progress and there is a demo.
Android: app design version 2.0 completed.
dcrdata: development of several chart visualizations was completed and is awaiting deployment. Specifically, voting agendas and historic charts are merged while ticket pool visualization is in testing.
atomicswap: @glendc is seeking reviews of his Ethereum support pull request.
Dev activity stats for July: 252 active PRs, 220 master commits, 34,754 added and 12,847 deleted lines spread across 6 repositories. Contributions came from 6-10 developers per repository. (chart)

Network

Hashrate: the month started at 40.5 and ended at 51.6 PH/s, with a low of 33.3 and a new all time high of 68.4 PH/s. F2Pool is leading with 40-45%, followed by the new BeePool at 15-25% and coinmine.pl at 18-23%.
Staking: 30-day average ticket price is 92.6 DCR (-2.1). The price started the month at 94.6 and quickly retreated to month's low of 85 until 1,860 tickets were bought within a single period (versus target 720). This pushed the pool of tickets to 41,970 (2.5% above target), which in turn caused 10 price increases in a row to the month's high of 100.4. This was the highest ticket price seen on the new ticket price algorithm which has been in effect since Jul 2017. Second half of the month there was unusually low volatility between 92 and 94 DCR per ticket. Locked DCR held between 3.75 and 3.87 million or 46.6-48.0% of supply (+0.1% from previous peak).
Nodes: there are 212 public listening and 216 normal nodes per dcred.eu. Version distribution: 67% on v1.2.0 (+10%), 24% on v1.1.2 (-1%), 7% on v1.1.0 (-7%). Node count data is not perfect but we can see the steady trend of upgrading to v1.2.0. This version of dcrd is notable for serving compact filters. The increased count of such full nodes allows the developers to test SPV client mode in preparations for the upcoming v1.3.0 release.

ASICs

Obelisk posted three updates in July. For the most recent daily updates join their Discord.
New miner from iBeLink: DSM7T hashes Blake256 at 7 TH/s or Blake2b at 3.5 TH/s, consumes 2,100 W and costs $3,800, shipping Aug 5-10.
There were also speculations about the mysterious Pangolin Whatsminer DCR with the speed of 44 TH/s at 2,200 W and the cost of $3,888, shipping November. If you know more about it please share with us in #pow-mining channel.

Integrations

Meet new stake pool: dcrpool.ibitlin.com has 1% fees and is hosted by @life.
An interesting detail about decredbrasil.com stake pool was posted in chat:
emiliomann: stakebrasil is one of the pools with the lowest number of missed and expired tickets. It was one of the first and has a smaller percentage than the most recent ones who haven’t had the time to do so. (...) The Brazilian pool should be the one with the more servers spread around the world: 6 to decrease the latency. This is to explain to you why the [pool fee] rate of 5% (currently around 0.06 DCR) on the reward is also one of the highest. girino: 8 voting wallets now. I just finished setting up a new one yesterday. All of them in different datacenters, 3 in europe, 3 in north america, 1 in brazil and one in asia. We also have 3 more servers, 1 for the front end, one for "stats" and one for dcrdata. (#general)
On the mining side, Luxor started a new set of pool servers inside mainland China, while zpool has enabled Decred mining.
StatX announced Decred integration into their live dashboard and public chat.
Decred was added to Satowallet with BTC and ETH trading pairs. Caution: do your best to understand the security model before using any wallet software.

Adoption

VotoLegal update:
Marina Silva is the first presidential candidate in Brazil using blockchain to keep all their electoral donations transparent and traceable. VotoLegal uses Decred technology, awesome use case! (reddit)
The story was covered by criptonoticias.com (translated) and livecoins.com.br (translated), the latter received hundreds of upvotes and comments on brasil.
On the OTC trading front, @i2Rav from i2trading reports:
We continue to see institutional interest in DCR. Large block buyers love the concept of staking as a way to earn additional income and appreciate the stakeholder rights it affords them. Likening a DCR investment to an activist shareholdebondholder gives these institutions some comfort while dipping their toes into a burgeoning new asset class.

Marketing

Targeted advertising reports released for June and July. As usual, reach @timhebel for full versions.
Big news in June: Facebook reversed their policy on banning crypto ads. ICO ads are still banned, but we should be OK. My team filled out the appeal today, so we should hopefully hear something within a few days. (u/timhebel on reddit)
After couple weeks Facebook finally responded to the appeal and the next step is to verify the domain name via DNS.
A pack of Stakey Telegram stickers is now available. Have fun!

Peter Todd's RBF (Replace-By-Fee) goes against one of the foundational principles of Bitcoin: IRREVOCABLE CASH TRANSACTIONS. RBF is the most radical, controversial change ever proposed to Bitcoin - and it is being forced on the community with no consensus, no debate and no testing. Why?

Many people are starting to raise serious questions and issues regarding Peter Todd's "Opt-In Full RBF", as summarized below:
(1) RBF violates one of the fundamental principles of the Bitcoin protocol: irrevocable cash transactions.
Interesting point!
Th[is] really is [a] drastically different vision of what Bitcoin according to the core dev team...
It would be nice [if] they [wrote their] own "white paper" so we know where they are going...

Intentionally doing zero-conf for any reason other than expediting a payment to the same recipients is nothing more than attempted fraud. There needs to be a good reason for enabling this, and last time I looked the case has not been made.
People with a black and white view of the world who believe "0 conf bad, 1 conf good" simply do not understand how bitcoin works. By its random nature, bitcoin never makes final commitment to a transaction. Even with six confirmations there is still a chance the transaction will be reversed. In other words, bitcoin finality is not black and white. Instead, there is a probability distribution of confidence that a transaction will not be reversed. Software changes that make it easier to defraud people who have been reasonably accepting 0 conf transactions are of highly questionable value, as they reduce the performance (by increasing delay for a given confidence).
If transactions with appropriate fees start failing to ever confirm because of "block size" issues, then bitcoin is simply broken and, if it can not be fixed bitcoin will end up as dead as a doornail.

Transactions spending the same utxo were (until now) not relayed (except by XT nodes). So it wasn't as simple as just sending a double spend, because the transaction wouldn't propagate. FSS-RBF seemed like a good option to get your tx unstuck if you paid too little. Pure RBF I'm not sure what the point of it is. What problem is it solving?

When F2Pool implemented RBF at the behest of Peter Todd they were forced to retract the changes within 24 hours due to the outrage in the community over the proposed changes.
So the opposite is actually true. The community actively do not want this change. Has there been any discussion whatsoever about this major change to the protocol?

(3) RBF breaks zero-conf. Satoshi supported zero-conf. Were any actual merchants who have figured out pragmatic business approaches using zero-conf even consulted on this radical, controversial change?
My business accepts bitcoin and helps people with minor cash transfers and purchases. Fraud has NEVER been an issue as long as the transactions have been broadcast on the blockchain with appropriate fees. We usually send people their cash as soon as the transaction is broadcast.
Now we have to wait 10 minutes to avoid getting cheated out of hundreds of dollars, vastly increasing the service cost of accepting bitcoin. And we have to tell customers we promote bitcoin to that they are likely to be cheated if they don't wait 10 minutes while buying their bitcoin. It is such a spectacularly stupid thing to do, adding uncertainty and greater potential for fraud at every link of the transaction chain. Thanks a lot, Peter.

Jeez, we need to give this "zero-conf was never safe" meme a rest already. Cash was also "never safe", but it's widely used because it works reasonably well in the context it's used. These people would probably advocate for a cashless society as well.

I believe it'll be possible for a payment processing company to provide as a service the rapid distribution of transactions with good-enough checking in something like 10 seconds or less.
The network nodes only accept the first version of a transaction they receive to incorporate into the block they're trying to generate. When you broadcast a transaction, if someone else broadcasts a double-spend at the same time, it's a race to propagate to the most nodes first. If one has a slight head start, it'll geometrically spread through the network faster and get most of the nodes.
A rough back-of-the-envelope example:
1 0
4 1
16 4
64 16
80% 20%
So if a double-spend has to wait even a second, it has a huge disadvantage.
The payment processor has connections with many nodes. When it gets a transaction, it blasts it out, and at the same time monitors the network for double-spends. If it receives a double-spend on any of its many listening nodes, then it alerts that the transaction is bad. A double-spent transaction wouldn't get very far without one of the listeners hearing it. The double-spender would have to wait until the listening phase is over, but by then, the payment processor's broadcast has reached most nodes, or is so far ahead in propagating that the double-spender has no hope of grabbing a significant percentage of the remaining nodes.

Zero conf was always dangerous, true, but the attacker is rolling a dice with a double spend. And it is detectable because you have to put your double spend transaction on the network within the transaction propagation time (which is measured in seconds). That means in the shop, while the attacker is buying the newspaper, the merchant can get an alert from their payment processor saying "this transaction has a double spend attempt". Wrestling them to the ground is an option. Stealing has to be done in person... No different then from just shop lifting. The attacker takes their chance that the stealing transaction won't be the one that is mined.
With rbf, the attacker has up to the next block time to decide to release their double spend transaction. That means the attacker can be out of the shop and ten minutes away by car before the merchant gets the double spend warning from their payment processor. Stealing is not in person and success is guaranteed by the network.
Conclusion: every merchant and every payment processor will simply refuse to accept any rbf opt in transaction. That opt in might as well be a flag that says "enable stealing from you with this transaction"... Erm no thanks.
There might be a small window while wallet software is updated, but after that this " feature " will go dark. Nobody is going to accept a cheque signed "mickey mouse", and nobody is going to accept a transaction marked rbf.
Strangely, that means all this fuss about it getting merged is moot. It will inevitably not be used.

(4) What new problems could RBF create?
This opens up a new kind of vandalism that will ensure that no wallets use this feature.
The way it works is that if you make a transaction, and then double spend the transaction with a higher fee, the one with the higher fee will take priority.

(5) RBF apologists such as eragmus have been trying to placate objections by repeatedly emphasizing that this version of RBF is ok, saying that this is only "Opt-In (Full) RBF". But does the "opt-in" nature of this particular implementation of RBF really mitigate its potential problems?
"opt-in" is a bit of a red-herring.
As I understand: say I'm a vendor who doesn't want to accept RBF transactions. So I don't opt-in. I'm still stuck accepting RBF transactions because the sender, not the receiver, has the control.

Yes it is opt-in, which means I have to anticipate ... congestion beforehand to use it. This has caused me troubles recently. Normally I use low-fee mode to transact and switch mode when the network is congested. A few times either I did not know about the congestion or forgot to switch mode and my txn got stuck for 12-48h. So for me this opt-in does nothing of help. If I was conscious about the congestion I would have switch to high-fee mode, no RBF needed.
...Or I have to enabled RBF for all my txns. Then there's problem of receivers have to all upgrade their wallet after the wallet devs choose to implement it. And just to add one more major complication when consider 0-conf.

"Hopefully this will give Bitcoin payment processors a financial incentive to support Lightning Network development."
https://www.reddit.com/bitcoinxt/comments/3ujq69/uriplin_on_rbitcoin_inadvertently_reveals_the/
It seems to me like RBF is addressing a problem (delays due to too-low fees) which would not exist if we had larger blocks. It seems fishy to make this and lightning networks to solve the problem when there's a much simpler solution in plain view.
We should set the bar for deceit and mischief unusually high on this one bc there is so much at stake, an entire banking empire.

RBF makes sense in a world where blocks are small and always full.
It creates a volatile transaction pricing market where bidders try to outbid each other for the limited space in the current block of txns.
It serves the dual goals of limiting transactions and maximizing miner revenue resulting from the artificial scarcity being imposed by the block size limit.
The unfortunate side effect is that day to day P2P transactions on the Bitcoin network will become relatively expensive and will be forced onto another layer, or coin.

(7) RBF violates two common-sense principles:
- "KISS" (Keep It Simple Stupid);
- "If it ain't broke, don't fix it"
To say it a bit harsher but IMO warranted: P. Todd seems to be busy inventing useless crap and making things complicated for wallet devs...

https://www.reddit.com/btc/comments/3ujc4m/consensus_jgarzik_rbf_would_be_antisocial_on_the/cxfkwvi
(8) Why is the less-safe version of RBF the one being released ("Full") rather than the "safe(r)" version (FSS - First-Seen Safe)?
Peter Todd had proposed two different versions of RBF: "Full" vs "FSS" (First-Seen Safe).
"Full" is the more dangerous version, because it allows general double-spending (I can't even believe we're even saying things like "allows general double-spending" - but that's the kind of crap Peter Todd is trying to foist on us).
"FSS" is supposedly a bit "safer", because is only allows double-spending a transaction with the same output.
What's being released now is "Opt-In Full RBF".
First-seen-safe restricts replace-by-fee to only replacing transactions with the same output (prevents double spending).
The reason this feature is being added is they see Bitcoin as a settlement network, so when there's a backlog users should be able to replace their transaction with a higher-fee one so it's included. It's to deal with the cripplingly low blocksizes.
Someone should just implement and merge first-seen-safe, since that's much more non-controversial. Keeps 0-confs safe(r) while enabling re-submitting transactions.
tytyty_
https://www.reddit.com/bitcoinxt/comments/3uii16/on_black_friday_with_9000_transactions_backlogged/cxff3ej
I would have preferred first-seen-safe RBF, certainly. It can be a useful tool to just bump the transaction fee on an existing transaction.
coinaday
https://www.reddit.com/bitcoinxt/comments/3uii16/on_black_friday_with_9000_transactions_backlogged/cxf5eno
Ok, so if the only benefit of RBF is to unstick stuck transactions by increasing the fee; why did you use "Full RBF" instead of "FSS RBF"? Full RBF allows the sender to increase the fee and change who the receiver is. FSS (First-Seen-Safe) RBF only allows the sender to increase the fee, but does not allow the sender to change who the receiver is.
Tldr: FSS RBF should be enough to enable your wanted benefit of being able to resend stuck transactions by increasing their fee, but you chose Full RBF anyway. Why?
todu
https://www.reddit.com/btc/comments/3uighb/on_black_friday_with_9000_transactions_backlogged/cxfm5qb
The benefit of opt-in RBF:
Now, when a transaction is not going through because fee was accidentally made too low or if there is a spam attack on the network, a user can "un-stuck" his/her transaction by re-sending it with a higher fee. No more being held to the mercy of miners maybe confirming your transaction, or not. The user gets some power back.
If this was the actual problem at hand, why not restrict the RBF to only increasing the fee, but not changing the output addresses.
RBF in it's current form is nothing but a tool to facilitate double spending. That is, it lowers the bar for default nodes to assist facilitating double spending. Which is VERY BAD for Bitcoin, imho.
Serisouly, I don't know what's gotten into those devs ACK'ing this decrease in Bitcoin's trustwortiness.

(9) Peter Todd has a track record of trying to break features which aren't perfect - even when real-world users find those features "good enough" to use in practice. Do you support Peter Todd's perfectionist and vandalist approach over the pragmatist "good-enough" approach, and if so, why or why not?
Destroying something just because it isn't perfect is stupid. By that logic we should even kill Bitcoin itself.

(10) Could the "game theory" on RBF backfire, and end up damaging Bitcoin?
And what if some/all miners simply hold RBF-enabled transactions into a separate pool and extract maximum value per transaction i.e. wait until senders cough up more & more ...
A very dangerous change that will actively encourage miners to collaborate on extracting higher fees or even extorting senders trying to 'fix' their transactions.

(11) RBF is a controversial, radical change to the Bitcoin protocol. Why has Peter Todd been allowed to force this on our community with no debate, no consensus and no testing?
It's not uncontroversial. There is clearly controversy. You can say the concerns are trumped up, invalid. But if the argument against even discussing XT is that the issue is controversial, the easy ACK'ing of this major change strikes many as hypocritical.
There is not zero impact. Someone WILL be double spent as a result of this. You may blame that person for accepting a transaction they shouldn't, or using a wallet that neglected to update to notify them that their transaction was reversible. But it cannot be said that no damage will result due to this change.
And in my view most importantly, RBF is a cornerstone in supporting those who believe that we need to keep small blocks. The purpose for this is to enable a more dynamic fee market to develop. I fear this is a step in the direction of a slippery slope.
(12) How does the new RBF feature activate?
Does anyone know how RBF activates? I mean if wallets are not upgraded this could be very dangerous for users. Because even if its opt-in this could kill zero confirmation for good.

https://medium.com/@octskyward/replace-by-fee-43edd9a1dd6d
(15) If you're against RBF, what can you do?
the solution to all this, is actually rather simple. Take the power away from these people. Due to the nature of bitcoin, we've always had that power. There never was a need for an "official" or "reference" implementation of the software. For a few years it was simply the most convenient, the mo[s]t efficient, and the best way to work out all the initial kinks bitcoin had. It was also a sort of restricted field in that (obviously) there were few people in the world who truly understood to the degree required to make a) design change proposals, and b) code for them (and note that while up until now this has been the case, it's not necessary for these 2 roles to be carried out by the same people). The last few months' debates over the blocksize limit have shown and educated thst a lot of people now truly understand what's what. And what's more one of the original core-devs (Gavin), already gave us the gift of proving in the real world that democracy in bitcoin can truly exist via voting with the software one (or miners) runs, without meaning to.
BitcoinXT was a huge gift to the community, and it's likely to reach its objective in a few months. It seems an implementation of bitcoin UL will test the same principle far sooner than we thought.
So the potential for real democracy exists within the network. And we're already fast on our way to most of the community stop[p]ing using core as the reference client. Shit like what Peter pulled yesterday, I predict, will simply accelerate the process. So the solution is arriving, and it's a far better solution th[a]t it would be to, say, locking Peter out of the project. Thi[s] will be real democracy.
I also predict in a couple of years a lot of big mining groups/companies/whatever will have their own development teams making their internal software available for everyone else to use. This will create an at[]mosphere of true debate of real issues and how to solve them, and it will allow people (miners) to vote with their implementations on what the "real" bitcoin should be and how it should function.
Exciting times ahead, the wheels are already in motion for this future to come true. The situation is grave, I won't deny that, but I do believe it's very, very temporary.

Stake. Fish was founded in the Autumn of 2018 and has grown to become a leading service provider in the Staking economy.They provide secure and reliable PoS verification services for global blockchain projects and investors.
03.Moderator Interview
Moderator: can you introduce yourself?
Now I am the CFO of stake. Fish, and I got in touch with digital currency in June 2017. In July of the same year, I took charge of brand operation and market in wallet sector.I started to be in charge of stake. fish is a semi-old chive. In 2015, I started to invest in stocks.Back into the currency circle, also just for a field to continue when the "leek."My micro blog introduction is [leek], you can follow my Weibo: Zi Yu blockchain.
I am same as many other people, who like to use "leek" ridicule themselves, this self-black way, can comfort a little of my loss of mood.And by the way, you might be wondering, isn't CFO for finance?How do you come out to market?In fact,here F for CFO is F for Fish, which translates to chief Fish officer.
Moderator: what is exactly stake. fish doing?Can you introduce the key members of your team?
Stake. Fish has about 20 members with teams distributed in 10 different time zones.Our founder Wang Chun previously co-founded f2pool, the largest bitcoin and ethereum mine pool.At present, wang chun is building validation nodes based on different PoS networks, hoping to continue to make similar important contributions to the industry in this way in new areas.
Jun Kim, operations manager, is a former economic consultant who specialises in analysing different industries and their evolution.Kris Lucera, director of infrastructure, has 18 years of experience in building and managing secure Internet infrastructure;Dasom Song, marketing director, is the little sister of blockchain web celebrity in South Korea and has rich experience in social media operation.
In general, our teams from all over the world and different fields of expertise have come together to form a multicultural technology company.

(A part of team members of stake.fish)
Moderator: Recently, Staking**, which is the business model under the PoS mechanism, has become a common word.So is Staking the value investment under the tide of PoS mining?**
Categorizing staking as a form of investment is not the right way to view PoS networks.Staking is not an investment vehicle or product but a means to contribute to the safety of the Internet and to protect the general certificate from inflation.Staking is not the same as investing. The concept is different.
Moderator: Staking is generally rewarded because of the inflationary nature of tokens. During the last round of bull and bear trading, many projects have experienced the risk of collapse and depreciation.How to find the right project layout when the market upward channel opens, and exit before the possible downward trend in the future?
Staking is definitely validation, and the rewards of validation are definitely fascinating.Because PoS mine pool is not an investment company, but a professional verification service company.What we need to do is decide which network to set up the validation node on.The process of deciding what network to support depends on a number of factors, three of which are particularly important.
First, we need to make sure that the project does address important issues and will be used by developers and users over the next decade.
Second, its well-documented economics allow us to maintain costs and sustained inputs.
Third, the project team needs to have strong technical strength and good reputation.We don't offer investment advice.People should do their own research and make careful investment decisions when choosing projects.
Moderator: How did you learn about BOSCore and why did you run for BOSCore node?
I have a deep relationship with BOSCore. One of BOSCore's advisers, super jun, is my bole.We used to work together at shinxin, and he was my leader, and I knew some of the developers and community leaders who worked for BOSCore from a very early time, and they were very close friends, and they talked to me about BOSCore from a very early time.
We really began to know BOSCore and decided to run for office in April this year, when we held a meetup with BOSCore in Bangkok, we met up with BOSCore's strength this time!But it didn't go live until this month, and it's been a long time coming.We think BOSCore has a great future and will be widely used by developers and users in the next decade.We were EOS nodes, so deploying BOSCore was a natural progression.
Moderator: What do you think is the biggest advantage of stake.fish?
Our advantages can be summarized into three simple points as below:
The first is stable global services
Teams, verification nodes, and sentinel nodes are distributed around the world.Global round-the-clock monitoring operation, always properly maintain our various verification nodes.Our team members are located in ten time zones, including the United States, Europe, southeast Asia, South Korea and Russia.We are the global village, the real 24-hour online monitoring.
The second is the deep industry foundation
Founder wang chun co-founded F2Pool, the largest integrated mine pool.In PoS field, stake. Fish has always been widely praised in the community, taking the first place in Cosmos node with solid technology and community foundation.At present, BOSCore node is also the first place, thank you for your support.
The third is continuous security
Always putting safety first, Kris, the director of infrastructure, has been working on system architecture and infrastructure security for 18 years and can select the best solutions in the industry to put into practice.
Moderator: What are your current contributions to BOSCore?
We co-organized a community meeting with BOSCore in Bangkok in April at our Bangkok office. , we have been in deep cooperation with BOSCore's community activities. Even the 3s LIB upgraded meeting was hosted by me on behalf of stake. Fish, which you may remember happened several days ago.Of course, the most important thing is to become a stable running node to protect the stable running BOSCore network, which is the most important contribution.
Moderator: How do you plan to do for BOScore in the future?What's the plan?
The community leader of BOSCore has talked with me, and I hope we can continue to cooperate and promote the global activities of BOSCore in the future.What we're doing for BOSCore right now is building communities together.This is very important, because BOSCore is still a baby, it needs more people to protect it care about it.
We also try to put tools that we developed on other chains on BOSCore networks.It takes a little bit of time, but what you can do in the short term is build communities together.
Moderator: What are your Suggestions and expectations for BOSCore ecology?
It is suggested that BOS need be launched on the exchange as early as possible. Now it can only be bought on newdex, which is really inconvenient for ordinary investors and hard core investors are not many.Why we deployed the node for so long, because it was really impossible to buy the BOS.I really look forward to BOSCore bringing real prosperity to Dapp. BOSCore is very fast and hopefully brings revolutionary products, and 3-second irreversible is 50 times faster than EOS network.3 seconds is an understatement, and most of the time it is less than 2 seconds or even 1 second. This is an awesome thing, and I am looking forward to the development of BOSCore in the next ten years.
  1. Free Disscusion
Q1: what is staking?Can you explain it to the community in the simplest way?
Staking is just a means of PoS, Staking can form an economic ecology.In this ecosystem, everyone can become a participant, and the most important places to participate are nodes and currency holders.Let's make it easier. Let's call him staking.
Q2: What is the relation between Staking and PoS?
Profit is the means not the end, and Staking is the means not the end of PoS.
Q3:How will the rise of Staking economy affect the industry ecology?
As far as I am concerned, staking economy will become the first choice for most blockchain projects, and PoW needs higher cost to ensure safety.If the PoW algorithm used by the public chain is not unique, the potential risk of being attacked by 51 cannot be ignored.Of course, to exclude bitcoin, bitcoin is the most successful case of PoW.The new public chain adopts PoS, which is much simpler and more efficient.If the PoS network wants to carry out 51 attacks, it needs to buy 51% of the currency. This attack cost is very high, which guarantees the security of the PoS network.
Question 4: From which media platforms we could know more about stake. fish and the latest development of stake.fish?
