咱们好,欢迎来到由Web3基金会和万向区块链实验室共同举行的Web 3.0练习营!

Hello, and welcome to the Wanxiang Bootcamp with Web3 Foundation!

这儿要特别感谢咱们的合作伙伴万向区块链,接连两年与咱们合作举行这一活动。上一年,Web 3.0练习营一期取得了巨大的成功,信任本年的Web 3.0练习营二期也将成就特殊。全球共有53支优秀团队报名本次练习营,与上一年的报名数量相比翻了一番,预示着波卡生态正在飞速生长。

A special thank you to our partner Wanxiang Blockchain for the support and partnership for a second year running. Web 3.0 Bootcamp was a great success last year. And this year it can turn into a great success too. We received 53 high quality applicants global wise, which doubles the number of the applicants from last year, which is a strong indicator of the rapid growing dot" target="_blank">Polkadot ecosystem.

咱们很骄傲地看到,今日在场的团队通过3轮面试终究当选本次练习营。Web 3.0练习营的遴选流程是十分严厉的,今日的开幕典礼为各入营团队供给了一个,分享经历、彼此学习的好机会。本次练习营将为咱们供给高品质的练习和孵化支撑,在接下来的4个月中,我信任各入营团队将收获颇丰。

We're proud of the teams who've made it to the finals through three rounds of interviews. The bootcamp selection process is very strict. And it's a great opportunity for the participating teams to gather together, and share their experience, and learn from each other. This bootcamp is offering very high quality training and incubation. Teams I'm sure will benefit a lot from this four-month progression.

曩昔一年里,我埋头作业,确保波卡愿景可以顺畅达成。发展最杰出的毫无疑问是平行链体系。通过这一体系,团队将可以运转各自的平行链。同时,咱们在转接桥方面也取得了巨大的发展。转接桥可以协助链与外部的Substrate链、比特币及以太坊区块链进行交流。Frame方面咱们也取得了许多的发展,现在Frame里现已新增了许多有用的功能。特别值得一提是Frame API 2.0,我觉得它将为技术还不是很老练的团队供给许多协助,也会让新链的搭建变得愈加简单,由于它就像是一个傻瓜版的Rust。

So since in the last 12 months, I've been busy beavering away, working on making sure that the Polkadot vision is delivered. The specific things that we've achieved a lot of progress on obviously is the parachains system Accumulus, the means by which teams going to be able to run their parachains. But just as important, I also made a real big progress on the bridges, which is going to facilitate, you know, chains talking to external substrate chains, as well as Bitcoin and Ethereum. So we've also made huge amounts of progress in Frame. There's an awful lot of extra really useful functionality in Frame now. In particular, the version two of the Frame API, which really I think it will be of great help to people whose skills are not so mature, and it will allow those who want to make, build new chains a much easier time, because it's so much more like idiomatic Rust.

别的,我还想跟咱们分享的是,XCMP和XCM都取得了重大发展,现已超额完结了许多作业,有些是咱们事前没有预见到的,可是这些作业同样十分重要,例如Queuing,例如确保链与链之间存在公开的交流机制,从而保障经济安全。别的咱们新增了许多工具和测验结构,许多人或许还没有发现咱们新增了这些东西,咱们新增这些东西是为了在上线时,确保体系安稳、可靠。

Not wanting to forget, we've also made you know substantial progress on XCMP and XCM the messaging format. There's a lot of extra work that has been done, that wasn't sort of initially foreseen. But there was very important, things like Queuing, things like making sure that there's a chat mechanism for opening channels between chains, so that we've got economic safety. And there's, yeah, I mean, a lot of additional tooling and test frameworks that you wouldn't maybe otherwise be aware of. There are there in order to make sure everything is robust and reliable.

说到上线进程,咱们或许都看到了,咱们围绕Rococo测验网做了许多作业。曩昔几个星期,咱们在Rococo进行了拍卖测验,也在Rococo上上线了测验平行链,验证者数量增加到900个,达到了Kusama的水平。这也增强了咱们的决心,咱们信任即它很快就可以正式上线了。

When it does actually launch, in terms of timeline, we have, I think probably most of you have seen, but yeah, if not, we've been working a lot on the Rococo test net. The Rococo parachains test net over the last few weeks, and we've launched test auctions on Rococo. We've launched test parachains on Rococo with increased number of validators up to the level of Kusama 900 validators. So we're getting increasingly confident that this is ready for production.

就在不久前,咱们发布了波卡客户端0.9版别,为关心1.0版别的团队供给平行链支撑。在1.0版别中咱们将终究供给全速XCMP服务,咱们现在阶段运用的是0.9系列。平行链也将和这一系列一起上线。咱们在敦促Kusama验证者进行更新,咱们同时也敦促波卡验证者进行更新,由于咱们将首先在Kusama上上线平行链。咱们将省略审查流程,让验证者用更短的时刻完结更新,将节点数据同步到0.9版别中去。我计划在接下来一周左右的时刻里,验证者完结更新后,咱们给验证者富余的时刻推动0.9版别,进行运转环境晋级,做最终的查看,在Kusama上上线第一条平行链。

And in fact, we've now released only a couple of days ago, a version 0.9 of the Polkadot client which will bring in parachain support for those who are interested in 1.0 when we've got the final, full speed XCMP support. So 0.9 series, we'll be here for a little while, and it's the series that parachains will launch with. So that logic is in we're now pushing validators on Kusama to upgrade and in turn validators on Polkadot obviously. Since we're launching parachains on Kusama first, and we're not waiting for the audit for that. So, validators will be on a shorter time scale to actually get the nodes of data to 0.9. And I would expect once validators have updated probably in about a week to give them all ample time to get 0.9 rolled out, we will issue a runtime upgrade, do our last checks, and put our first parachain on Kusama live. 

这第一条平行链将命名为 “Shell”,咱们编写了新的运转环境。这仅仅一个暂时的过渡环境,之后咱们会将Shell平行链晋级为真正活泼的平行链,Shell之后会被更新为正常的好用的平行链。接下来几周或许还会出现另一条正常的好用的平行链,别的,不久之后拍卖也将开端。咱们至少会提前一周通知咱们,让咱们免除Kusama上的质押,也让Kusama上的团队有时刻决议要不要进行团体借贷或是采纳其他做法。

This will be a what's called a "Shell" parachain, this is a new runtime that we coded up. That basically is just staging ground, so that we can then upgrade the Shell parachain into a real, sort of live parachain. In this case, Shell will be upgraded to the statement, common, good parachain. There may be another common, good parachain in the weeks following. But beyond that auctions will, I think begin, very shortly afterwards. We'll give at least one week's notice, so that people on Kusama have chance to unstake, and so that teams on Kusama have chance to make it clear that they are doing a crowd loan or whatever else

平行链已是呼之欲出,感谢咱们耐性等待,成功就在前方。也感谢咱们参加Web 3.0练习营,期望咱们都能在这儿取得所需的支撑和激励,为波卡的发展做出更多奉献,下次再见!

So yeah, we are very much on the Eve of getting parachains out there. So thanks for your patience, but I hope we won't have too much longer to wait. Thanks a lot guys for taking part in bootcamp. I hope you're getting the support and encouragement. That you need to really build some great stuff for Polkadot until next time.
