Gavin Wood:波卡启动第二阶段NPoS网络_巴比特_服务于区块链创新者

详情页1

来源:PolkaWorld,作者:Gavin Wood,翻译:PolkaWorld 社区

 

Polkadot 主网的第一个候选链 CC1 已经稳定运行了两个多星期了,是时候进入下一个阶段了。如你所知,Polkadot 网络的启动分为几个阶段,首先是基于权威证明(PoA)共识的一个中心化的、有限制和许可的网络。在我写这篇文章的时候,这个 PoA 初始阶段已经运行了 19 天,它没有任何问题,希望即将到来的事情也会这样稳定。在此期间,我们对网络进行了七次升级以添加或修改功能,引入了很有用的用户管理和帐户管理功能,并进一步展示了 Polkadot(以及Polkadot 使用的 Substrate 框架)的非凡灵活性。是时候继续前进了!由于已经有很多 DOT 持有人认领了他们的代币,并且有许多人将他们的代币绑定和 staking,网络已经准备好过渡到新的提名权益证明(NPoS)共识算法 。截至本文撰写时,已有 193 个节点表示他们有意成为波卡网络上的验证人。保守起见(和 Kusama 一样),我们将从 20 个验证人开始,慢慢增加数量,初步目标是在今年秋天达到 1000 个验证人(已经有 400 个验证人安全运行在 Kusama 上,目前没有看到任何问题)。

过渡
下面是它的具体工作方式。我刚刚将一个 Sudo 交易推送到网络上,然后网络使用调度程序模块(Scheduler pallet )(在之后,通过 sudo 之类的治理特权来源在波卡上执行任意操作都很简单)来调度一个特殊的 Staking.ForceNewEra 然后它将使 PoA 切换到 NPoS。我们计划在第 #325,148 个区块进行,预计于明早 7:30(Zug 时间,中国时间是 6 月 18 日 下午的 13:30 )左右完成。这是一个很好的选择,因为它几乎正好是在 9:30 左右结束 1200 个区块的共识 session 的过程中。此时,将选择下一个 staking 设置集。现在,按照 Babe(我们的底层区块生产协议)的工作方式,每个验证人节点池都会在退出之前再待上一个 session 的时间。这样,新选择的抵押的验证人将在一个完整的 session(约 4 小时)后开始生成其第一个区块,因此我们可以预期该网络将在瑞士楚格时间大约 13:30,中国时间是 6 月 18 日下午 19:30 完全过渡到 NPoS。

在这之后…
过渡完成后,我们将进入启动的第二阶段,并期待着下一个里程碑,即第三阶段。根据我们最初的路线图(基于 Kusama 的启动),第三阶段是引入治理机制,例如理事会和公投,而第四阶段是移除 Sudo(并终止许可)。实际上,这些可能在很短的时间内甚至可能同时实施。与阶段二一样,我们希望能够在 2-4 周内到达阶段三。在阶段四之后,还有阶段五,即通过新启用的治理系统在去中心化的、未经许可的网络上开启余额转账功能。一旦在接下来的几周完成了开发和审计后,我们就可以看到第六阶段——第一个平行链的推出!如果想成为的验证人的话,你应该去 Polkadot Validators Lounge(https://riot.im/app/#/room/#polkadotvalidatorlounge:web3.foundation)。前往 Polkadot JS Apps,进行映射、认领和 Staking。想了解有关 Polkadot 的更多信息,请访问官网 https://polkadot.network/。 v0.8 客户端代码可以在 GitHub 发布页面 https://github.com/paritytech/polkadot/releases 上找到。原文链接:https://medium.com/polkadot-network/polkadot-launch-phase-2-e45c635031ef
