Block Version Number in BitcoinThe block version number in Bitcoin serves as an indicator of which set of consensus rules a block follows. It's also used to signal miners' readiness or support for upcoming protocol upgrades. Over time, block version numbers have evolved from simple sequential numbers (like versions 1 through 4) to a more complex bit-field system, which allows for multiple upgrades to be signaled at once.From last time you badgered me I made some notes. Evolution of Block VersionsEarly Versions (1-4):These were straightforward indicators of protocol changes. For example:Version 1 was used from the Genesis block until March 2013.Version 2 came with BIP 34, authored by Gavin Andresen, it added the block height to the coinbase transaction and was activated at Block 227,931 on March 27, 2013.Version 3 enforced stricter signature validation with BIP 66, authored by Pieter Wuille, it ensured correct DER encoding of signatures. It activated at Block 363,725 on July 4, 2015.Version 4 enabled CheckLockTimeVerify (CLTV) with BIP 65, also authored by Pieter Wuille, it allowed for time-locked transactions and activated at Block 388,381 on December 11, 2015.Then come the Version Bits format:Bitcoin upgrades were becoming increasingly complex, the block version system transitioned to the Version Bits signaling mechanism, which allows multiple protocol changes to be signaled at once using specific bits in the block version field, allowing miners to signal support for up to 29 features simultaneously, each represented by a specific bit in the 32-bit version field.When Segregated Witness (SegWit) was introduced, Bitcoin transitioned from simple block versions to the complex numbers seen today.Special Note: before we review the important key version bits, I have to make something clear. These version numbers are more than just sequential; they signal specific changes using bitsI am going to call out version numbers like 536 870 912, which is is the decimal representation of the hexadecimal value 0x20000000The full number 536870912 in binary is 00100000000000000000000000000000.“536" doesn't have standalone significance. It's just a part of the decimal value when the binary representation of 0x20000000 is converted into base 10 (which equals 536870912).The important part lies in the bitwise representation, where the leading bits "001" in the binary form, are reserved for signaling purposes, indicating that version bits are being used.But for the purpose of conveying version numbers to a human (this human being you Max) we will use the decimal representation instead of 0x2 nd a bunch of zeros or 001 and 29 more zeros.Now to the bit version section…Version 536 870 912 indicated readiness for SegWit, introduced through BIP 141 (authored by Pieter Wuille). SegWit was activated on August 24, 2017, at Block 481,824.Version 536 870 913 was used to signal support for BIP 91 and authored by James Hilliard. BIP 91 lowered the threshold required for SegWit's activation. It was locked in at Block 477,120 on July 20, 2017.Version 536 870 914 and 536 870 916 continued signaling for SegWit deployment through various BIPs.How It Works TodayToday, miners use the Version Bits system to signal support for new upgrades, and they must keep their block version numbers in line with consensus rules. Version numbers like 536870912 (SegWit) are still recognized by the network, and each bit in the version number, a miner can signal support for different soft forks simultaneously.For instance, if the network is ready for a future upgrade, miners will flip the corresponding bit in their block version number, signaling their support for the upgrade. The rest of the version field remains intact, allowing multiple soft forks to be signaled at the same time.First 3 bits = 001: Reserved and indicate version bits are being used.Remaining 29 bits: Available for signaling specific soft forks or protocol changes. Each of these bits corresponds to a different potential feature being activated.Car Analogy for Bitcoin Block Version NumbersLet's compare Bitcoin's block version numbers to Fords and how their cars evolved from simple model numbers to VIN numbers that represent various features and changes in their design over the years.The Model T and Block Version 1:Just like Ford's Model T, the first Bitcoin blocks (version 1) were basic, so basic, buyers didn't even have a choice in what color vehicle they could buy “you can have a car in any color so long as its black. Similar to early block versions that had no special features—the first blocks had no complex rules or signals, just the essentials.Evolving Model Years and Version Numbers:As Ford expanded its lineup, more models came out, and so did the need for differentiating cars beyond going from model T to Model A. Apply that to Bitcoin, version 1 to 4 were indicators of upgrades like block height (BIP-34), stricter validation (BIP-66), and time-locked transactions (BIP-65) can be compared to model T to model AComplex Version Bits = New Ford VIN Structure:Eventually, car manufacturers standardized more details in its VIN numbers to reflect all the specifics of each model the world manufacturers identifier, vehicle description section, and the vehicle identifier section—just like Bitcoin's version bits system, which allows for more granular signaling.The VIN was introduced in 1965 to track each vehicle's specifications. The first two characters of the VIN, such as “1F,” identify Ford and where the vehicle was built. 1F is a Ford built in the USA.For example, characters 4-8 in a Ford VIN indicate engine type, body style, and model, much like Bitcoin's complex version numbers (536 870 912 or 0x20000000) that signal specific features like SegWit (BIP-141) or BIP-91 activation.Or version 536 870 916 (0x20000004) signals both SegWit and BIP-91—much like how characters in the Ford VIN specify the engine, body, and trim level of a car.VINs were more standardized in the 80's. Ford's VIN numbers now include production year, plant location, and a unique serial number to distinguish every car (that's characters 10-17). Likewise, Bitcoin's version bits (introduced with version 536870912) can signal multiple protocol changes at once. Just as the tenth digit in a VIN tells you the model year (e.g., “J” for 1988), a Bitcoin version number can tell you which upgrades are active. Bits 1-3: Reserved for version signaling format (for example, the top three bits set to 001 for soft fork signaling).Bits 4-32 can each represent a specific feature or soft fork proposal, meaning multiple upgrades can be signaled simultaneously within the same block version field.ConclusionIn both cases, as the products (Fords and Bitcoin blocks) became more complex, the identifiers also became more detailed. From simple model numbers like T and A (Max likes T & A) to VIN numbers, Bitcoin's version bits both allow for greater customization and finer control.Like how car manufacturers track and signal changes to its cars over time with VINs, Bitcoin uses block version numbers to ensure the network continues to evolve. Bitcoin is still Bitcoin, and a Ford is still a Ford regardless of the fact Henry Ford is dead, and Satoshi is not Craig Wright, or Adam Back, or Peter Todd.

Glad you asked.. (https://bitcoinrollups.org/) Originally described by Goldwasser, Micali, and Rackoff in their 1985 paper "The Knowledge Complexity Of Interactive Proof Systems", zk proofs are a type of cryptographic proof defined as "those proofs that contain no additional knowledge other than the correctness of the proposition in question". Greg Maxwell, who wrote about "zero knowledge contingent payments" in the Bitcoin Wiki in 2011. Maxwell later worked with Sean Bowe, Pieter Wuille, and Madars Virza to implement the protocol in 2016.34 In May 2013, Miers et al published the Zerocoin paper, showing how zk proofs could be integrated directly into the bitcoin protocol to hide the addresses involved in a bitcoin transaction Feedback Remember to get in touch bitcoindadpod@protonmail.com or @bitcoindadpod (https://mobile.twitter.com/bitcoindadpod) on twitter Consider joining the matrix channel (https://matrix.to/#/#bitcoin:jupiterbroadcasting.com) using a matrix client like element (https://element.io/get-started), details here (https://www.jupiterbroadcasting.com/community/matrix/) Thank you Boosters If you get some value from this show, please consider sending a boost.

In this episode of The Van Wirdum Sjorsnado, hosts Aaron van Wirdum and Sjors Provoost discuss the Erlay protocol. Erlay is a proposal to reduce the bandwidth required to run a Bitcoin node, which has been proposed and developed by University of British Columbia researchers Gleb Naumenko, Alexandra Fedorova and Ivan Beschastnikh; Blockstream engineer Pieter Wuille; and independent Bitcoin Core contributor Gregory Maxwell. Bitcoin nodes use bandwidth to receive and transmit both block data as well as transaction data. Reducing the amount of bandwidth a node requires to do this, would make it cheaper to run a node. Alternatively, it allows nodes to connect to more peers without increasing its bandwidth usage.   In the episode, Aaron and Sjors explain that Erlay uses set reconciliation to reduce the amount of data nodes need to share transactions. More specifically, Erlay uses a mathematical trick called Minisketch. This solution is based on pre-existing mathematical formulas used in biometrics technology. Aaron and Sjors outline how this trick is applied in the context of Bitcoin to let different nodes sync their mempools: the sets of transactions they've received in anticipation of a new block, or, in the case of a miner, to include in a new block.

For our first episode, we talked to Bitcoin Core contributor Pieter Wuille. Pieter has been a Bitcoin protocol developer and contributor to Bitcoin Core since 2011. In that time, he's authored or contributed to some of the most important developments, including segwit, bech32, libsecp, HD wallets, schnorr and taproot, and many others. We talked to Pieter about his thoughts on some of those influential PRs, including headers-first syncing and ultraprune, and hear about the motivation for those changes and how he thinks about them now. This is a two-parter and in the next episode, we'll hear about libsecp and Pieter's thoughts about Bitcoin in 2020.

For our second episode, we pick up where we left off with Pieter Wuille in episode 1. If you missed that one, you should go back and listen to it first. Pieter has been a Bitcoin protocol developer and contributor to Bitcoin Core since 2011. In that time, he's authored or contributed to some of the most important developments, including segwit, bech32, libsecp, HD wallets, schnorr and taproot, and many others. We talked to Pieter about his thoughts on the lessons learned from the March 2013 Consensus Fork as well as libsecp and Pieter's thoughts about Bitcoin in 2020. Discussed in this episode: Lessons learned from the 0.8 consensus failure (1:00) BIP66 - Strict DER signatures (3:13) Satoshi's usage of OpenSSL (3:47) OpenSSL and DER encoding (5:35) libsecp256k1 (12:12) Hal Finney's post on the special properties of the secp256k1 (12:50) Peter Dettman and Bouncy Castle (16:58) Imagining P2SH from the beginning (26:20) If you like this, find more shows at podcast.chaincode.com.

Location: San Fransisco Date: Monday 22nd July Company: Blockstream Role: Co-founder Pieter Wuille is one of the most influential, respected and prolific Bitcoin developers. While his career began at Google, the appeal of working on  Bitcoin's open-source protocol was too tempting and led him to co-found Blockstream.  Pieter has had a significant influence on the Bitcoin project and has the third most commits on the codebase. He has helped to implement some of the most significant changes to the protocol, including Segregated Witness, one of the most contentious hard forks in Bitcoin's history.  As others debate the Bitcoin roadmap, Pieter has managed to remove himself from the infighting; instead, focusing his time on improving Bitcoin.  As such, he's now working on implementing Taproot, Schnorr Signatures and MAST. In this interview, we hear how Pieter first heard about Bitcoin in 2010, entering the world of mining and selling thousands of Bitcoin for $0.20. I also find out what he thinks of Bitcoin in 2019 and what he argues is the threat to its future. Bonus: we also hear from a Blockstream intern at the end about his experience working at Blockstream and supporting Pieter in developing Bitcoin.

In this episode of The Unhashed Podcast: Charlie Lee wants to add confidential transactions to Litecoin. Is this just Litecoin further acting as a test bed for Bitcoin or are they trying to distinguish themselves by attempting to one up their big brother? Canadian Exchange Quadriga is never ending source of news and drama as of late. Is the CEO pulling an Elvis and faking his death to exit scam with the money or were they just another shoddily run exchange that had everyone fooled? And...has Pieter Wuille come up with Esperanto equivalent of bitcoin scripting? 0:00:00 Episode Summary0:01:49 Introduction0:04:05 Litecoin Adding Confidential Transactions?0:18:10 Difference between Coinjoin and Confidential Transactions0:21:21 QuadrigaCX "Liquidity Issues"0:49:50 NEM Foundation on brink of Insolvency1:05:33 Miniscript1:12:23 ICO, My God They're Serious - XYO1:25:50 Lightning RoundMake sure to check out Billfodl for all your hardware wallet backup needs

本期 Fork It 我们有幸请到了鲁汶大学 COSIC 实验室博士生张韧 (https://twitter.com/nirenzang)来和我们聊聊 MimbleWimble，在本期 Fork It 中，张韧将 MimbleWimble 拆分成了 Confidential Transaction、Coin Join、 OWAS 三部分进行阐述，非常清晰，期间他解释了一些外界对 MimbleWimble 的误解，很具启发性。 张韧还谈到了他 2013 年花了一年时间设计自己的 PoW 算法，但最终没有发文的遗憾，而这个遗憾背后的考虑也是 Grin 存在的最大的安全隐患，至于是什么，听听这一期 Fork It 就知道了。 本期讨论到了比特币教父 Adam Back、修改并完善了 MimbleWimble 协议的 Andrew Poelstra、 和 IACR 的前任主席，RIPEMD-160 设计者 Bart Preneel 等在加密领域做出了杰出贡献的学者和开发者。 除了在泛用型播客客户端收听订阅《 Fork It 》，您还可以在喜马拉雅 (https://www.ximalaya.com/keji/19792413/) 和网易云音乐 (https://music.163.com/#/djradio?id=792240368)收听节目。 What are you waiting for?

On tonight's episode of "The Crypto Show," Rod from Dash Brazil and Brian Deery, Chief Scientist at Factom, join us in studio while we talk to Andrew Poelstra, Pieter Wuille and Benedikt Bunz through Internet magic boxes. We discuss zero-knowledge proofs in all their varieties, details, and implementations. We discuss the differences between snarks, starks, and bullet proofs, their various advantages and trade-offs, and what problems each is most suitable for solving. Toward the end Benedict shares some quick info on the cryptographic material on which they are working at Stanford and gives credit to those whose work became the foundation for their "bulletproofs" work.

In the midst of the heated blocksize debate one could be forgiven to think that there is very little Bitcoin developers are able to agree on. Yet, when core developer and Blockstream co-founder Pieter Wuille introduced the concept of segregated witness at the Scaling Bitcoin conference in Hong Kong most of the Bitcoin community quickly rallied behind the proposal. Eric Lombrozo, CEO of wallet company Ciphrex and responsible for running the segregated witness testnet, joined us to discuss the proposal and its implications. Segregated witness, it turns out, does not only provide an elegant way to increase the blocksize via a soft-fork, it also solves transaction malleability and greatly simplifies updating the Bitcoin’s scripting language. It’s a crucial topic and may well enable a new wave of accelerated innovation in Bitcoin. Topics covered in this episode: The various benefits of segregated witness The mechanics of segregated witness How segregated witness solves transaction malleability How segregated witness could increase the blocksize to 2-3MB with a soft fork What segregated witness means for wallet developers How segregated witness could facilitate development of off-chain networks such as Lightning Network The important difference between hard forks and soft forks How segregated witness will allow updates of Bitcoin’s script language via soft forks Episode links: Scaling Bitcoin Talk by Pieter Wuille Let's Talk Bitcoin! #277 Separating Signatures with Segregated Witness Gavin Andresen: Segregated Witness is Cool Bitcoin Magazine Series on Segregated Witness Part 1 Part 2 Part 3 Eric Lombrozo's company Ciphrex This episode is hosted by Brian Fabian Crain and Sébastien Couture.
