20181112比特币现金(BCH)的全节点实现Bitcoin SV在11月10日进行的比特币现金专业压力测试预览中表现出众。运行新Bitcoin SV客户端的挖矿组织在nChain的BMG矿池中成功挖出了五个32 MB大小的区块,是目前为止已挖出的最大区块。 这是在公有链中挖出的最大区块,完全填满了比特币现金协议当前设置的最大区块大小。 在11月15日网络升级及竞争比特币现金实现方式之间的哈希算力大战即将拉开帷幕之时,这场预测试展示了为什么与Bitcoin ABC和其它全节点实现方式相比,Bitcoin SV是矿工们更好的选择。

预测试结果同样还验证了Bitcoin SV与日俱增的哈希算力支持。 11月11日 ,Coin.dance公布的数据预测Bitcoin SV的支持者目前占整个比特币现金网络哈希算力的58%到68%之间,相比之下,Bitcoin ABC仅获得了19%到32%的哈希算力支持。 自Coin.dance在11月15日硬分叉之前开始报道哈希算力数据以来,Bitcoin SV是第一个超过总预估哈希算力支持50%的比特币现金实现方式。 随着一家最近发起的中国矿池Mempool宣布将运行Bitcoin SV,Bitcoin SV的支持预计将进一步上升。 可以证明拥有哈希算力支持的Bitcoin SV可以持续地得到来自矿工的工作,这些矿工们承诺一如既往地支持比特币现金网络。

比特币现金专业压力测试旨在测试比特币现金区块链的吞吐量。 测试团队由Play.BCH.cash提供支持,独立于任何全节点实现团队,在进行11月17日的主测试前,于11月10日进行了预测试。 测试团队部署了一个覆盖不同地区、拥有50多个节点的网络,并使用了Bitcoin SV、Bitcoin ABC与Bitcoin Unlimited实现客户端。 预测试期间,测试团队在超过四个小时的测试期间创建并发送了1,578,504笔交易,相当于每小时400,000笔交易。

在区块高度556034,BMG矿池挖出了世界上有史以来第一块大小为32 MB的区块。 仅仅两个小时之后,BMG在高度556045、556046、556048和556049几乎同时又挖出了四个32 MB区块,每个区块中包括超过166,000笔交易。 测试团队的报告详细记录了这一系列“令人震惊”的发现,“这四个区块很短时间内就在BMG矿池中先后挖出,这证明了其基础设施已经准备好支持大于32 MB的区块。” BMG矿池是隶属于区块链研究与开发公司nChain旗下的挖矿组织。

其它使用Bitcoin SV的挖矿组织在预测试中同样挖出了非常大的区块。 SVPool挖出20.6 MB大的区块,而CoinGeek挖出了15.4 MB大的区块。

相比之下,运行Bitcoin ABC的矿池在预测试过程中挖出的区块则要小得多。 ViaBTC在区块高度556035仅挖出了一个大小为8 MB的区块,而且预测试期间使用Bitcoin ABC挖出的大多数区块最大为1 MB左右。

预测试证明了Bitcoin SV对于扩容路线图的想法是正确的, 即比特币现金区块链可以承受更大的区块,并且能够快速扩展来适应大型企业的应用。 Bitcoin SV的名字来源于比特币的创始人中本聪所提出的“中本聪愿景”(Satoshi Vision),旨在恢复最初的比特币协议、使其保持稳定并且大幅度扩张,从而可以成为供数十亿人使用的全球性网络。 对于即将在11月15日到来的协议升级,Bitcoin SV将把默认区块大小上调至128 MB。 相比之下,Bitcoin ABC将沿用之前32 MB的默认区块大小限制。

Bitcoin SV的首席开发工程师丹尼尔·康诺力(Daniel Connolly)说道:

“其它开发组织说,比特币现金软件无法承受大于22 MB的区块。 现在,我们用Bitcoin SV证明了即使是大于32 MB的区块也能顺利挖出。 我十分期待看到在启用128 MB的默认最大区块设置之后,能看到更大的区块。 总有一天,我们会取消默认区块大小限制,让矿工们自己进行区块设置。
区块越大,复杂交易类型就会起丰富,而矿工们就能收取更多的交易手续费。”

除了扩展性以外,比特币现金协议的稳定性也十分重要。 Bitcoin SV的技术总监丹史蒂夫·施德斯(Steve Shadders)评论说:

“只有比特币现金区块链的协议保持稳定,而不是每个六个月就要由于开发组织希望尝试新的操作法或更改功能而面临好不必要的变更,国际企业才会使用这种区块链。 我们希望让比特币现金协议回归到中本聪最初的愿景,并且让其保持稳定,就像不会经常发生变更的互联网协议一样。”

施德斯还总结了矿工在11月15日硬分叉后面临的抉择:

“对于世界各地的比特币现金矿工来说,正确的选择是Bitcoin SV。 我们提供的这条道路可以通往中本聪最初对比特币提出的愿景,这能帮助矿工提高交易收入并且在未来的岁月里保持盈利。”

 位于安提瓜的CoinGeek提出创建并资助了Bitcoin SV项目,而nChain发起了最初的开发工作。 位于安提瓜的bComm协会以全球比特币现金社区的名义拥有该项目,而Bitcoin SV的代码则在MIT许可协议下开源。 若想了解更多有关Bitcoin SV的信息,请访问www.bitcoinsv.io

Bitcoin SV excels in BCH Stress Test preview, reaches over 50% hash support

12 November 2018 –  Bitcoin SV, the new full node implementation for Bitcoin Cash (BCH) excelled in a November 10 preview of the BCH Professional Stress Test. Mining groups running the new Bitcoin SV client mined by far the biggest blocks, with nChain’s BMG Pool successfully mining five 32MB size blocks. That is the largest block size ever mined on any public blockchain, and completely filled the default maximum block size currently set on the BCH protocol. In advance of the November 15 network upgrade and hash war between competing BCH implementations, this pre-test demonstrated why Bitcoin SV is a superior choice for miners over Bitcoin ABC and other full node clients.

The preview test results also validate the growing hash support for Bitcoin SV. On November 11, Coin.dance data estimated that Bitcoin SV now has support ranging from 58-68% of the total BCH network hash, compared to Bitcoin ABC with only 19-32%. Bitcoin SV is the first BCH implementation to cross over 50% estimated hash support since Coin.dance began reporting such data in advance of the November 15 hard fork. Bitcoin SV’s support is expected to increase even more, as Mempool, a new Chinese mining pool recently launched and will run Bitcoin SV. The hash backing Bitcoin SV is sustained Proof of Work from miners committed to support the BCH network on an on-going basis.

The BCH Professional Stress Test is designed to test the BCH blockchain’s throughput capacity. Powered by Play.BCH.cash and organized independently of any BCH full node implementation team, the testing group ran a November 10 pre-test in advance of its main November 17 test. The test team deployed a network of over 50 nodes in geographically dispersed locations and using Bitcoin SV, Bitcoin ABC and Bitcoin Unlimited client implementations. During the pre-test, the group created and sent 1,578,504 BCH transactions over a period of 4 hours, or around 400,000 transactions per hour.

At block height 556034, BMG Pool mined the world’s first ever 32MB block. Just two hours later, BMG mined  four more 32MB blocks almost consecutively at block heights 556045, 556046, 556048, and 556049 – with each block containing over 166,000 individual transactions. As the test team’s report observes about this “astounding” series, “[t]hese 4 blocks were all mined by BMG pool in rapid succession showing that their infrastructure is ready for blocks larger than 32MB.” BMG Pool is the affiliated mining group of blockchain research and development company nChain.

Other mining groups that use Bitcoin SV – CoinGeek and SVPool – also mined very large blocks during the pre-test. SVPool mined a 20.6 MB block, and CoinGeek mined a 15.4MB block.

In comparison, mining pools running Bitcoin ABC achieved much smaller blocks during the pre-test. ViaBTC mined a single 8MB block at block height 556035, but most other blocks mined using Bitcoin ABC were at most 1-2 MB during the pre-test.

The preview test confirmed that Bitcoin SV is correct about its scaling roadmap: the BCH blockchain can handle much larger blocks and can more quickly scale for big enterprise use. Named for the “Satoshi Vision” of Bitcoin’s creator Satoshi Nakamoto, Bitcoin SV intends to restore the original Bitcoin protocol, keep it stable, and allow it to massively scale to a global network used by billions of people. For the upcoming November 15 protocol upgrade, Bitcoin SV will lift its default maximum block size to 128MB. In contrast, Bitcoin ABC client will keep its default block cap at its current 32MB.

Bitcoin SV’s lead developer Daniel Connolly remarks:

“Other developer groups said BCH software could not handle blocks above 22MB. We’ve now shown with Bitcoin SV that even 32MB size blocks can be mined. Once we go to a 128MB default maximum block setting, I look forward to seeing even bigger blocks. One day, we will lift the default block cap altogether so that miners can configure their own block settings. Bigger blocks will allow more diversity of complex transaction types and more transaction fees for miners.”

In addition to scalability, stability of the BCH protocol is important. Bitcoin SV Technical Director Steve Shadders comments:

“Global businesses will operate on the BCH blockchain only if its protocol remains stable, rather than facing unnecessary changes every 6 months by developers who want to add some experimental new OP_code or feature change. We want to restore the BCH protocol to Satoshi’s original design, and then keep it stable just like the Internet protocol does not often change.”

Mr. Shadders summarized the choice facing miners for the November 15 hard fork:

“For BCH miners around the world, the correct choice is Bitcoin SV. We provide the path to achieve the original Satoshi Vision for Bitcoin, which will enable miners to generate more transaction revenue and remain profitable for years to come.” 

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 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. For more information about Bitcoin SV, visit www.bitcoinsv.io.

Bitcoin BCH stress test shows positive results

This past September, a stress test of the Bitcoin BCH blockchain was held. The results were more satisfactory than many had expected, with 10 megabyte (MB) and 21MB blocks mined. By the end of the test, 2.1 million transactions were completed and Bitcoin BCH accounted for over 60% of the crypto traffic over the period the tests were conducted. In preparation of another stress test on November 17, CoinGeek has been running some minor stress tests and the results are impressive.

As seen in the CoinGeek mining chart below, a number of blocks measuring 32MB were mined. This is important, as it shows that CoinGeek’s mining efforts are more advanced than others, and that it is capable of routinely mining larger blocks.

Some will try to argue that large block mining is irrelevant because cryptocurrency has yet to make a significant penetration into the merchant ecosystem. However, this is a fallacy and the mentality of procrastinators who don’t understand the importance of having the system ready before it’s needed -not after. By developing the network now and looking toward the future, there won’t be a need to scramble at the last minute to introduce changes.

Everyone, at some point or another, has become frustrated in a shopping experience because the retailer wasn’t prepared for the response it received. Lack of preparation leads to delays in purchasing, delivery, loss of revenue and a generally poor customer experience. All of these can be avoided if the network is prepared ahead of time.

Being able to demonstrably prove that the Bitcoin BCH network is capable of massive amounts of simultaneous transactions will show the world that it is capable of leading the way toward wider acceptance of cryptocurrency for its original purpose – a peer-to-peer currency that is meant to give control back to the money holders.

CoinGeek’s test is a step toward showing the viability of its mining pool and the strength of its support team. While others are satisfied waiting around to see how the future plays out, CoinGeek is determined to not only be a part of the future, but to shape it, as well.

BCH Professional Stress Test scheduled for November 17

After the success of the first Bitcoin BCH stress test on the first of September, the group behind that test have decided to ramp up their efforts to showcase the robustness and reliability of the of the BCH Network.

The group plans a more extensive, more professional stress test on November 17, two days after the scheduled protocol upgrade.

Rather than I tell you about the upcoming stress test, Brenden Lee of https://stresstestbitcoin.cash has put some words on the page to give some insight into their group, their processes and what everyone can expect come November 17.

The Professional Stress Test

“Our team came together to bring the first stress test to life, and while the test itself was something of a success, the 2.2 million transactions were a far cry from the target we had set for ourselves of 5 million transactions.

The reasons were wide-ranging and included a lack of automated systems for re-starting tests that failed, issues with the way some nodes were managing transaction buffers, and a lack of people to run the testing and manage the system.

After the test, a small group of us came together to look at forming a professional testing group, and the idea of the professional stress test was born.

Dale Dickins is an early Bitcoin activist and the maker of a documentary called “The Bitcoin Doco.” She works tirelessly to build networks of people who use Bitcoin, creating small social worlds to achieve great things. She has recently been part of the group who brought the Bitcoin Cash Jeepney to the streets of Manila and is working on forming long-term business relationships in Bitcoin.

Esthon Medeiros is the wizard behind the curtain, building and managing the test machinery, currently being referred to as the ‘Satoshi Shotgun,’ which has significantly evolved since the first test. We now can create many geographically dispersed nodes using multiple Bitcoin clients (we currently support Bitcoin Unlimited, Bitcoin SV and Bitcoin ABC) and can easily regather funds and send large numbers of transactions for a sustained period. The machine’s power will be on display during the upcoming pre-test which we hope will achieve at least one 32MB block.

Brendan Lee is the author of BUIP086 which extends the functionality of Bitcoin QR codes and developed and now sells the patented Safewords system through his company Coin storage Guru, while more recently has been fortunate enough to be part of the team at Tokenized, recently awarded the Coingeek Token prize. His role has been planning the strategy for ensuring money and resources are available on the day as well as acting as a technical interface for customers.

John Goldberg is the creator of the innovative Pixel Wallet (an Android BCH wallet that uses pictures to send cash) and was a significant contributor to the original stress test and one of the core members of the BCH Jeepney team, who were the first to implement Handcash’s POP Retail system in a real-world application.

We also have Spark who created some fantastic data visualizations for the first stress test and is working on ways to capture the essence of what happens during this stress test.

And finally, Yobits who was the originator of the Stress Test idea and as webpage master has done a great job putting together a beautiful website.

As for the stress test itself, we want it known that we are not here to break things. We, as a team, are aligned with Satoshi Vision, however, have decided to run the test in such a way that a network supporting current rules, or the ABC ruleset would face minimal disruption.

The test will challenge mempools, and users may have to pay slightly higher fees than usual (test transactions will carry a fee of just 1sat/byte, so transactions with two satoshis/byte should usually be mined in the next block regardless of the state of the mempool) for reliable transaction confirmations. However, we believe that if a network wants to call itself Bitcoin, it must be able to show the world that it is anti-fragile, and this includes withstanding attacks that I would consider relatively cheap (we will spend about 70BCH over the course of the day) for a well-funded state based actor to execute.

We are very strong proponents of scaling Bitcoin and believe that a successful demonstration of a public network processing over a million transactions per hour will send a huge signal to businesses and the broader public that Bitcoin Cash is serious about adoption, and serious about becoming a global cash network. We hope that we can generate enough hype through this test that companies looking at implementing cryptocurrency-based payments will put Bitcoin Cash first, as it forges a path towards being the best money possible.

Following the stress test, the team is working on a business plan to create value-added services around generating large volumes of transactions on the blockchain for things such as advertising, corporate testing, stress testing and more. The team is very much looking forward to announcing these efforts soon. – Brendan Lee

Bitcoin Cash Professional Stress Test all set for Nov. 17

The biggest test ever conducted on a public blockchain is coming to Bitcoin Cash (BCH)—the Bitcoin Cash Professional Stress Test.

November is shaping up to be the busiest month for the Bitcoin BCH community. On November 15, the network will execute another network upgrade, with Bitcoin SV entering as a new full node implementation for the BCH blockchain, intended to advance the Satoshi Vision of Bitcoin’s original protocol design and with a plan for faster scaling to bigger blocks on BCH. Bitcoin SV will raise the maximum default block size to 128MB (from its current 32MB) as another step toward massive on-chain scaling, in addition to re-enabling of the original “Satoshi” set of op_codes, particularly OP_MUL, OP_LSHIFT, OP_RSHIFT, and OP_INVERT.

To put the newly-upgraded network to a test, the team behind the successful September 1 BCH stress test is gearing up for yet another professional stress test on November 17—two days after the protocol upgrade. The BCH stress test team operates independently of the BCH implementation groups.

“We are aiming to process over 24 million transactions within a 24 hour period on the main BCH chain. Processing over 24 million transactions will showcase the Bitcoin BCH network capacity today, and will be a positive signal for merchants, businesses and investors, giving them confidence in the Bitcoin BCH network and its ability to scale on-chain,” the stress test team stated on its website.

A “Taste Test” of the Bitcoin Cash Professional Stress Test will take place on November 1 at 12:00 UTC, followed by a Warm Up Test on November 10 at 12:00 UTC. The Main Test is scheduled for November 17 at 12:00 UTC.

The November professional stress test will use the same TX blaster that was created for the original stress test, but with significant upgrades to enable it to handle higher volumes of transactions for longer periods of time. The upgraded TX Blaster, according to the organizers, manages incoming UTXOs into transaction parcels which it then blasts onto the network, generating large numbers of transactions very fast.

To help fund the stress tests, the team is asking for contributions from the Bitcoin BCH community.

For its warm up test on November 10, which will demonstrate the TX blaster’s capability of generating 1 million transactions, the team has set a goal of raising 5-10 BCH. The funds will be received into a multisig address managed by the team, and all excess funds will be held over for the main stress test.

For the main event test on November 17, the team has set up a range of tiered sponsorship levels, each representing a slice of the per-second transaction volume that will be broadcasted to the network during the 24-hour duration of the test. Additional funds received beyond the targeted 300tx/second will be used to extend the duration of the stress test.

Fall’s most important Bitcoin BCH conference

Capping off the eventful November is the CoinGeek Week Conference in London on November 27-30.The four-day conference will kick off with Miners Day—an invitation-only event designed to help cryptocurrency miners better understand how mining is evolving and where miners can discuss latest advancements in the BCH community, such as the new Bitcoin SV implementation for Bitcoin BCH.
