Scaling-focused changes now available with Bitcoin SV version 0.1.1

Scaling-focused changes now available with Bitcoin SV version 0.1.1

True to its roadmap of enabling massive, secure on-chain scaling, the Bitcoin SV node team rolled out on Monday the updated version of the Bitcoin SV (BSV) client.

The BSV version 0.1.1 adds scaling improvements that will deliver “crucial capacity and performance increases to transaction propagation,” according to the node team. These include faster relaying of transactions to enhance security of instant transactions and larger network messages for handling higher volumes of transactions, as well as increased parallelization of network communication.

Among the notable changes in BSV version 0.1.1 are the removal of random delay, parallelization of inventory-handling code, increase in inventory message size and in max protocol message size. The DNS Seed servers were also updated to exclude the Bitcoin Cash (BCHABC) network; the updated node client also features optional logging of transactional sources; and large invalid block messages will now cause ban instead of disconnect.

Another important update to the 0.1.1 version is the addition of the Scaling Test Network (STN).

“The scaling-focused changes in the release have all been researched and tested in the private Gigablock Testnet which is now being relaunched publicly under the new name: Scaling Testnet (STN),” the Bitcoin SV node team said.

Available on GitHub, the BSV 0.1.1 version features the advances used to achieve the sustained 64MB blocks for straight 24 hours, which showed that the network is capable of delivering constant rates of over 300 transactions per second continuously during a full 24-hour period “with no problem.” Tests for 128MB blocks are already underway, and according to BSV Node lead developer Daniel Connolly, the early results are encouraging.

The global Scaling Test Network is open to anyone in the BSV ecosystem interested in participating in a “continuous flow of transactions with rates reaching 700 transactions per second.” This initiative, according to the node team, paves the way for the creation of an environment where scaling capabilities of existing solutions and scaling technologies can be researched and verified. To learn more about STN, visit the Bitcoin Scaling Test Network site.

The Bitcoin SV version 0.1.1 builds on the improvements made in the initial release candidate, which focused on protocol stability. This time, the node team rolled out modifications that enable massive scaling of the BSV network, allowing major enterprises to build confidently on top of the regulation-friendly BSV chain. As Twitter user Brendan Lee noted: “Bitcoin [now reborn in Bitcoin SV] is scaling on-chain, ready for the world to jump on-board.”

Bitcoin SV version 0.1 goes live

Bitcoin SV 第0.1版正式上线

领先区块链技术研发机构nChain将于11月对比特币现金(BCH)网络进行升级,在升级前一个月,nChain于本月15日推出了Bitcoin SV客户端的最终测试版本。最终测试版本推出后,nChain鼓励比特币现金(BCH)矿工和矿池开始尝试使用Bitcoin SV。

Bitcoin SV中的“SV”是Satoshi Vision(中本聪愿景)的缩写。Bitcoin SV提供了一种全新的全节点比特币现金(BCH)实现方式,旨在实现中本聪(Satoshi Nakamoto)最初在其比特币白皮书中所设定的愿景。与其他竞相对比特币作出不必要变更的竞争性比特币现金(BCH)实现方式不同,Bitcoin SV的开发规划路线图在于恢复中本聪的初始协议、保持协议稳定性、进行大规模扩容、继而允许大型企业放心地在稳固的比特币现金(BCH)基础上开发创建项目活动。

Bitcoin SV 第0.1版发布在 GitHub,上,其中重新启用了OP_MUL、OP_INVERT、OP_LSHIFT和OP_RSHIFT这些中本聪操作码,为11月份即将进行的比特币现金(BCH)升级提供了前期支持。接受区块的默认最大规模软限制也从32MB提升至128MB。

在为期5周的公开测试结束后,本最终测试版本仅对公测版作出了一项重要变更,即将每个脚本的操作码数量限制提升至500,这一变更并未完全解除操作码限制。Bitcoin SV团队计划在完成其严格质量保证框架下的进一步测试流程后完全解除操作码限制。

本最终测试版通过禁用家庭用户的特色功能(如图形用户界面(GUI)和Windows支持),对用户进行了简化整理,重点关注企业用户核心受众。SV项目的技术总监史蒂夫•施德斯(Steve Shadders)提出:“现在,是时候带领比特币走上精准的专业化发展道路了。因此,Bitcoin SV将企业用户设定为其目标用户群体,用户主要包括矿工及一些加密货币交易所和商家。通过移除不必要的功能,我们可以集中精力开发核心用户群真正关心需要的功能。”

此外,本次最终测试版本还移除了2018年5月升级的自动重播功能和激活逻辑,同时还引入了针对恶意同行行为,特别是所谓的“无限块攻击”的保护功能。

展望未来,Bitcoin SV将更加注重比特币现金(BCH)的可扩展性。SV项目的首席开发员丹尼尔·康诺利(Daniel Connolly)解释到:“对于本次的最终测试版本,我们的开发重点在于,通过变更集最小化来实现协议的稳定性。在后续版本中,我们计划进行更新升级,以实现比特币现金(BCH)网络的大规模扩容,为全球大型企业的使用提供足够的容量支持。”

Bitcoin SV被评选为几大最有前景的比特币现金(BCH)节点实现方式之一,Bitcoin SV的开发目的旨在赋予矿工权利,让矿工来指导比特币的未来发展,并确保比特币现金(BCH)矿工保持盈利能力。矿工将拥有选择权和发言权,借此推动比特币恢复至最佳状态 — 即采用无限容量区块、初始操作码以及在协议上未强加任何人为限制的状态。

但为何现在即需开始扩容?根据nChain集团首席执行官吉米·阮(Jimmy Nguyen)解释,原因非常简单:矿工有直接的经济需求。

近期在泰国召开的2018曼谷比特币未来峰会上,阮解释了从现在开始急需对区块规模进行快速扩容的原因:“在未来两年内,区块奖励将再次减半,预将减至6.25个比特币现金(BCH)。在区块奖励减半的情况下,现在采矿的矿工两年后的收入将减至现在的一半。为了保持矿工目前的盈利能力,矿工需要在两年内通过其他方式补足6.25个比特币现金价值,这也就意味着交易费用必须增加并且交易量必须有所提高。”   事实上,为了保持矿工的盈利能力,到2020年,比特币现金(BCH)网络需要达到千兆字节区块规模,因此,必须从现在开始进行大规模扩容。

Bitcoin SV项目是应安提瓜岛的CoinGeek Mining要求在其赞助下创建的,项目开发工作由nChain完成。Bitcoin SV项目由安提瓜岛的bComm协会代表全球比特币现金(BCH)社区所有,Bitcoin SV代码根据开源MIT许可证进行提供。

Bitcoin SV version 0.1 goes live

Bitcoin SV version 0.1 goes live

Leading blockchain technology research and development outfit nChain has rolled out the release candidate of the Bitcoin SV client on October 15—one month ahead of the November Bitcoin Cash (BCH) network upgrade. BCH miners and mining pools are encouraged to begin using Bitcoin SV.

Bitcoin SV, which stands for Satoshi Vision, is a new full-node implementation for Bitcoin BCH designed to fulfill the vision set out by Satoshi Nakamoto’s original Bitcoin white paper. Unlike other competing BCH implementations which seek to make unnecessary changes to Bitcoin, Bitcoin SV’s roadmap is to restore the original Satoshi protocol, keep it stable, enable it to massively scale, and allow major businesses to confidently build on top of BCH.

Available on GitHub, the Bitcoin SV 0.1 version includes support for the November upgrade, including the re-enabling of these Satoshi op_codes: OP_MUL, OP_INVERT, OP_LSHIFT, and OP_RSHIFT. The default maximum size of accepted blocks has also been increased from the 32MB soft limit to 128MB.

After spending five weeks in public beta, this release candidate makes only one significant change from the beta version: raising the limit on the number of op_ codes per script to 500 rather than removing it altogether. The Bitcoin SV team intends to remove the op_code limit entirely at a later time, after further testing as part of its rigorous QA framework.

This release has streamlined to focus on its core audience of business users by disabling featured meant for home users such as GUI and Windows support. Steve Shadders, Technical Director of the SV Project, said: “It’s time for Bitcoin to professionalize.  Therefore, Bitcoin SV is targeted at business users, primarily miners but also cryptocurrency exchanges and merchants. By eliminating unnecessary features, we can keep the development focused on what really matters to our core user base.”

Additionally, the automatic replay feature and the activation logic for the May 2018 upgrade, have been removed. The release version also introduced protections against malicious peer behavior, notably the so-called “infinite block attack.”

Going forward, Bitcoin SV will focus more on scalability of BCH. Daniel Connolly, lead developer for the SV project, explains: “For this initial release candidate, we focused on stability for the protocol by minimizing the change set. For future releases, we plan updates to enable massive scaling of the BCH network so that it can support major enterprise usage globally.”

Considered one of the most promising Bitcoin BCH node implementations, Bitcoin SV is born out of the desire to empower miners to direct the future of Bitcoin and also to ensure BCH miners remain profitable. Miners will have a choice and a voice to drive the process of restoring Bitcoin to its optimal state—that of unbounded blocks, original op_codes, and no artificial limits imposed on the protocol.

But why now? The reason, according to nChain CEO Jimmy Nguyen is simple: There’s a direct economic need for miners.

At the recently held The Future of Bitcoin Summit Bangkok 2018 in Thailand, Nguyen explained why it is important for the block size to scale now—and scale fast: “In two years the block reward will be split in half again to 6.25 BCH. So anyone who’s mining now will in two years receive half of what they’re receiving today. In order to maintain even current profitability, what that means is in two years they have to make up that 6.25 coins worth of value in something else, which has to come in transaction fees and which has to come in higher transaction volume.”

The Bitcoin SV project was created at the request of and sponsored by Antiguan-based CoinGeek Mining, with development work initiated by nChain. The project is also owned by the Antiguan-based bComm Association on behalf of the global BCH community, and the Bitcoin SV code is made available under the open source MIT license.

GitHub puts ICOs under the microscope

GitHub puts ICOs under the microscope

Anyone will tell you that writing computer code is a tedious, cross-eyed-inducing task. It’s important that the code be succinct and clean by the time the final product is ready, which, when dealing with tens of thousands of lines of code, can be a daunting process. However, code that is created properly results in a quality product that projects user confidence and ensures that the application works as planned. GitHub, a web-based hosting service for version control using git, hasn’t been too concerned with coding quality, but the days of lax coding could soon be a thing of the past.

There are more than 20 million users and over 57 million repositories on GitHub. Anyone can upload their code and it has become a popular destination for initial coin offering (ICO) and altcoin projects.  The portal serves as a central location where coding projects can be reviewed, bugs can be tracked and team members from anywhere around the world can provide their input. The majority of the uploaded projects, including those for cryptocurrencies, are open source, which means that the public also has access to the projects.

The public access is one potential drawback to GitHub. An individual could potentially take another’s code, modify it and then publish it as his or her own. That public access is the tricky part. An unscrupulous individual can take the code, tweak it and try to pass it off as his or her own. Several tools now include coverage of projects on GitHub to weed out the imposters and the projects that show signs of manipulation, news.bitcoin.com first reported.

Cryptomiso is one of these tools. It recently added GitHub to the sites it monitors and allows for GitHub data to by filtered based on several criteria. Onchainfx is similar to Cryptomiso, but goes beyond filtering. It also includes a ranking system that is based on project commits, stars, number of viewers watching the project and the number of lines added or removed. Both tools are valuable methods of analyzing ICO and crypto code, but have one drawback. Neither allows results to be ranked by quality, only frequency.

Probably one of the most useful “tools” is actually a human. Andre Cronje, a popular cryptocurrency blogger, has begun to invest a lot of time and energy researching new projects that are uploaded to GitHub. Once his research is complete, he publishes his findings on his Twitter feed, @AndreCronjeTech. His in-depth analysis paints a brighter picture of which projects are worthy, and which ones don’t deserve a second glance.

With so many new projects coming on line these days, it’s increasingly difficult to discern the good ones from the bad. These tools offer a more solid means to evaluate a cryptocurrency’s proficiency and to gauge its authenticity. As with any investment—from buying a smart TV to buying cryptocurrency—it’s always important to perform the necessary due diligence and background checks to ensure the validity of the superficial information.

Note: Tokens in the SegWit chain are referred to as SegWit1X (BTC) and SegWit Gold (SWG) and are no longer Bitcoin. Bitcoin Cash (BCH) is the only true Bitcoin as intended by the original Satoshi white paper.  Bitcoin BCH is the only public block chain that offers safe and cheap microtransactions.
