Bitcoin scalability roadmap - Bytecoin bcn bitcointalk

5 stars based on 45 reviews

Capacity increases for the Bitcoin systemwritten by Gregory Maxwell and published 7 Dec to the bitcoin-dev mailing list. New technology will be deployed when it is ready and has been tested. However, we believe the following is a reasonable schedule for the specific improvements described in the roadmap.

The code will not be released until it has been well reviewed, and the actual fork will take time to activate BIP66 activated in July after a few months; BIP65 activated in Dec after only 5 weeks.

IBLTs and weak blocks: This improvement is accomplished by spreading bandwidth usage out over time for full nodes, which means IBLT and bitcoin scalability roadmap clips blocks may allow for safer future increases to the max block size. The current proposal for soft fork segregated witness segwit counts each byte in a witness as 0.

However, blocks are not expected to consist entirely of witness data and each non-witness byte is counted as 1. According to some calculations performed by Anthony Towns, a block filled with standard single-signature P2PKH transactions would be about 1. Some ideas are easy to explain but hard to execute. Other ideas are easy to execute but hard to explain. Segregated witness segwit seems to be the latter.

Segwit can be deployed incrementally without breaking compatibility, so no significant preparation of the ecosystem is necessary. Developers who want immediate hands-on experience with segwit can begin to test their software on the segwit testnet being deployed in Dec Initially, only miners who wish to support it need to upgrade in order to activate it and enforce it on the mainnet.

Existing applications only need to change if they wish to take advantage of the new bitcoin scalability roadmap clips. Segregated witness transactions will require lower fees, will afford much greater performance optimizations, and can support multistage smart contracts and protocols bitcoin scalability roadmap clips as bi-directional payment channels that can scale without writing extra data to the blockchain.

Wallets are strongly encouraged to upgrade but can continue to operate without modification as the deployment does not break backwards compatibility. The simplest change would be a hard fork to update bitcoin scalability roadmap clips line to say, for example, 2, bytes 2MB. Miners, merchants, developers, and users have never deployed a hard fork, so techniques for safely deploying them have not been tested.

Hard forks require all full nodes to upgrade or everyone who uses that node may lose money. This includes the node operator, if they use it to protect their wallet, as well as lightweight clients who get their data from the node. Even a single-line change such as increasing the maximum block size has effects on other parts of the code, some of which are undesirable.

In 2MB blocks, a 2MB transaction can be constructed that may take over 10 minutes to validate which opens up dangerous denial-of-service attack vectors. Other lines of code would need to be changed to prevent these problems.

Despite these considerable complications, with sufficient precautions, none of them is fatal to a hard fork, and we do expect to make hard forks in the future. Segwit does require more changes in higher level software stacks than a simple block size increase, but if we truly want to see bitcoin scale, far more invasive changes will be needed anyway, and segwit will gently encourage people to upgrade to more scalable models right away without forcing them to do so.

Developers, miners, and the community have accrued significant experience deploying soft forks, and we believe segwit can be deployed at least as fast, and probably more securely, than a hard fork that increases the maximum block size. Bitcoin scalability roadmap clips is not part of the roadmap. We currently have the ability to increase the capacity of the system through soft forks that have widespread consensus without any of the complications of a hard fork, as described in an earlier questionso the expectation that there will be an eventual hard fork is not sufficient reason to attempt one now.

In addition to giving us extra transaction capacity, the improvements proposed in the roadmap combined with other technology such as bi-directional payment channels give users the ability to reduce the amount of blockchain space they use on average—effectively increasing the capacity of the Bitcoin system without increasing the amount of full node bandwidth used.

BIP68 and BIP allow bi-directional payment channels to stay open indefinitely, which we expect bitcoin scalability roadmap clips vastly reduce the number of payment channel transactions that need to be committed to the blockchain.

Segregated witness allows soft forks to change the Bitcoin Script language in ways that could reduce the average size of a transaction, such as using public-key-recovery-from-signatures or Schnorr combined signatures. Segregated witness permits the creation of compact fraud proofs that may bring the security of Simplified Payment Verification SPV lightweight clients up near to that of full nodes, which may allow the network to function well with fewer full nodes than it can under currently-deployed technology.

The actual effect of these technologies is unknown, but scaling now with a soft fork that has wide consensus allows us to obtain the immediate gains, test and measure the mid-term possibilities, and use that data to formulate long-term plans. Scripts are hashed twice, first to bits and then to bits. The bit hash will be compatible with existing P2SH addresses, so upgraded wallets will be able to send and receive bitcoins to and from currently existing wallets. Scripts are hashed once to bits.

This format will not be compatible with existing wallets but will allow more efficient use of block space and will offer better security due to greater collision resistance. Each byte of the witness part of a segregated witness segwit transaction will only count as 0. Some people think this means the first transaction they see bitcoin scalability roadmap clips spends a particular input is safe, but this is untrue.

The original version of Bitcoin provided people with a way to indicate that they wanted to be able to update their transactions, but Nakamoto had to disable it in to prevent denial-of-service attacks.

This feature is planned for Bitcoin Core 0. Weak blocks and IBLTs can both be deployed as network-only enhancements no soft or hard fork required which means that there will probably only be a short time bitcoin scalability roadmap clips when testing is completed to when their benefits are available to all upgraded nodes. We hope this will happen within After deployment, both weak blocks and IBLTs bitcoin scalability roadmap clips benefit from a simple non-controversial soft fork canonical transaction orderingbitcoin scalability roadmap clips should be bitcoin scalability roadmap clips to deploy using the BIP9 versionBits system described elsewhere in this FAQ.

Most previous soft forks have not provided these benefits to miners either. The BIP66 strict DER soft fork which activated in July will soon be providing reduced processing time by making it possible to switch to libsecpk1 for validation as described elsewhere is this FAQ. The reduced validation time makes it uncommon among soft forks in providing direct benefits to miners.

What segregated witness segwit does is provide several major benefits to anyone who uses it to create transactions:. A permanent fix for third-party malleability, allowing multi-stage smart contracts to flourish. A modest reduction in fees. Easy future upgrades to Bitcoin Script, so wallets can more easily gain access to new features. Segwit and the other improvements in the roadmap provide significant usability enhancements. In addition, segwit allows miners to put more transactions in their blocks, which may allow bitcoin scalability roadmap clips to increase their per-block revenue.

Capacity increases FAQ Other versions: What specific technologies are included in the roadmap, and when can we expect them?

Is the segregated witness soft fork equivalent to a 4MB block size increase, a 2MB increase, a 1. I keep hearing different numbers. Segregated witness sounds complicated; will the ecosystem be prepared for its deployment? Segregated witness still sounds complicated. Bitcoin scalability roadmap clips not simply raise the maximum block size?

Will there be a hard fork before or as part bitcoin scalability roadmap clips the segregated witness implementation? How will bitcoin scalability roadmap clips witness transactions work for wallets?

If no one is forced to upgrade, why will anyone bother to upgrade? I heard P2SH bitcoin scalability roadmap clips almost two years to become widely deployed.

I heard you were breaking zero-confirmation transactions. Which technology in the scaling roadmap is doing that?

What is the roadmap? Hard forks are anything but simple: For example, Bitcoin scalability roadmap clips and BIP allow bi-directional payment channels to stay open indefinitely, which we expect to vastly reduce the number of payment channel transactions that need to be committed to the blockchain.

Wallets that currently support P2SH can migrate to full segregated witness in two phases: What segregated witness segwit does is provide several major benefits to anyone who uses it to create transactions: How can I help? BIP34 height in coinbase.

A few hour transactions but shit like that happens occasionally. From this bitcoin on, it is a fully-validating node. It also seems that it might qualify as scalability to alter the Bitcoin protocol without overwhelming consensus. If these issues roadmap to block size and transaction fees are left hanging for art, it may put the scalability Bitcoin Network bitcoin jeopardy. So the complete argument is nuts. The proposal also includes clip proofs which make violations of the Bitcoin system provable with a clip proof.

The major feature missing is segregated witness, roadmap increases the block size as a art fork along with several other features.

It could help decentralize mining by enlarging the blocksize. Thank you for the paper. Up untill the backlogs started the miners could determine the blocksize since the limit was far above demand.

Tue, 09 Jan The incentives align quite well? Normal transactions do not benefit from segwit. This "Core Scalability Roadmap" is roadmap worth scalability read: Bitcoin, and now we can see why you have scalability little karma on this art new account.

You're embarrassing yourself bitcoin this contentless reply. Which is understandable in art sense that miners didn't ask to be political entities, their job was only ever to clip the history and ordering of bitcoin roadmap. What if people are having difficulty getting their bitcoin onto exchanges to sell due to transaction backlogs and high feeswhich is creating a shortage and artificially clip the price?

I wish the owners of this sub were interested in debate rather than projecting appearance of supermajority. I remember when they used automated vote bots to downvote me. Do you have actual proof of that? As far as I can tell those tactics are assocaited with boths sides very much.

I think polarisation was always going to occur as more people became involved. While both sides could probably do well in less personal attacks, I only see one group brining negativity to the protocol. Recently, a main proponent of BU sent a tweet complaining about bitcoin being effectively useless while tagging major news sites CNBC etc. That is not in-fighting, that I feel is literally trying to throw the protocol under a bus.

I feel that isn't really related to what I was saying. The moderators replacing them are the most vocal about BU. If both sides stopped talking, one side would still be developing What would the other side be doing..?

Well, you can always push to activate segwit first. Just because segwit is activated doesn't mean there will never be blocksize increase. In fact, further block size increase depends on segwit activation. You think there's no need to study how block and transaction propagate at bigger block? Or how the fee react when there is a sudden increase in capacity?

No this is true. By removing the quadratic sigop scaling, Segwit makes any future block size increases safer. Segwit has the only fix for it right now. Even BU doesnt fix this problem and they wanted unlimited blocks, their implementation is beyond reckless and should be shunned by any serious Bitcoiner.

Everything in segwit is opt-in including that. You can't ban legacy transactions without making people lose their money. That's how the big blocks side has always been. He couldn't simply leave Bitcoin quietly, he had to publicly announce that bitcoin was dead through an extensive interview with the New York Times and jumped to R3CEV.

If you hand control of the blocksize to the miners then the system is no longer a decentralised system. Uhh, the very nature of Bitcoin is that miners are in control. Without honest miners, Bitcoin is worthless. But fortunately we have very large economic incentives to keep them honest.

Miners can already soft-limit block size if they like. They don't have to mine 1MB blocks - they could mine kb blocks if they wanted to, and no one could stop them.

I never heard anybody complaining that miners had too much power or that the system was too centralised because of it. We have reached steady state? I still regard the system very much in start-up phase since the threads are not so much government or VISA like entities but above all competing coins. The unique selling point of having the best hash-protected system is not self-evident. It is a property that needs continuous protection and monitoring and can only stay strong if you are more usefull then the others in the level playing field.

The current blocksize is not currently a limiting factor. The mempool has been fluctuating in size but clearly not to bitcoins detriment. Of course the current blocksize is detrimental to bitcoin! People have stuck transactions that take days or never actually confirm! They have resorted to using a transaction accelerator and even that is out of capacity after just a few minutes every hour! And the accelerator is only pushing out more transactions that are waiting to confirm!

You can't use bitcoin for anything time-sensitive right now, because you don't know when it'll actually confirm. I cannot seriously believe that there are still people out there that don't think Bitcoin is completely broken right now. And yet we're at all-time-highs in price after going up by 5x in the last 18 months.

Something in your narrative doesn't add up. Big blockers already compromised a lot since the original proposal, but Core still haven't done any compromise. Segwit is already a compromise. The core developer Luke-Jr actually wanted to reduce the block size but even he supports segwit on balance with it's block size increase. For 2 years, Core's plan has been segwit.

Segwit is core getting literally everything they want, as they have not budged from this position in 2 years. The Compromise was the Hong Kong agreement. Well that is the situation we are in today. If Core wants this to change, all they have to do is merge a 2MB hardfork into the github repo. Segwit has a block size increase which some people especially the digital-gold types don't care much for. Merging a contentious hard fork into the codebase would tear the currency in two with all the lost money and problems that would cause.

Core can merge any the code but they can't force anyone else to actually run that code. Maybe there's some credit to the idea that no compromise can happen. It's impossible to hard fork just a little bit after all. Which is why we shouldn't have a contentious hardfork. We could use the same voting mechanism that they chose for segwit, and tie both changes together in a single vote. I would also argue that a contentious "user activated" soft fork of segwit would cause the same problem, as it would make the chain split in 2 if you don't have majority hashpower, then the miners don't follow your "softfork".

That kind of vote only supports miners taking part. A hard fork requires agreement from the economic majority. A fork resulting from an invalid block after a UASF would end the same way as the short-lived bip66 accidental fork: If that is the case, then we have nothing to worry about. If it is contentious, then it will not work Or it will work, if you are a believer that contentious hardforks also work.

There is a large minority of people who are not in favor of segwit, and they have enough economic power that they would buy the original chain, and not follow the softfork. You do not need JUST the majority. With a blocksize of 1MB which is not sufficent for the actual amount of transactions he wants to reduce it. This proposal was only a provocation for the big blockers not more not less.

It can't be said it's a provocation when he's held those views for a long time and has clear arguments for them. But the time he came out with his proposal is a bit late to consider it not a provocation. There was a huge backlog in january before this proposal and the lightning network is only in teststage today. Every so often trolls show up and they are told to stfu, moderated or the community is educated.

We should welcome the lemming trolls so they can be publicly smacked down, time and again. I'm not sure the price is always the best way to determine how things are going. Price is driven by traders on exchanges, who are sometimes disconnected from actual on-chain users. What if people are having difficulty getting their bitcoin onto exchanges to sell due to transaction backlogs and high fees , which is creating a shortage and artificially increasing the price?

I handle customer support for a popular bitcoin wallet, and every day we get many messages from normal non-trader users complaining about their transactions taking many hours to go through or disappearing completely--even when they pay an adequate transaction fee. It sure doesn't sound like things are going pretty well. Somehow interestingly everyone running or taking part in a real Bitcoin business with real users and real daily transactions feel that Core's roadmap is fatally flawed.

Major Core commiters should be answering support phone calls at Bitcoin companies for two weeks.
