ETH 2.0 烽火链启动结果、第一阶段及以后的发展情况

Quantstamp Announcements
November 30, 2020

The Beacon Chain launched today on December 1st, 12 PM UTC. On November 24th, the deposit contract reached its deposit threshold of 524,288 ether, making the Beacon Chain eligible for launch 7 days later. Additional ether has been deposited since this threshold was met: as of Dec 1st 8:12 AM UTC, 877,249 ETH (worth over 500,000,000 USD) is staked in the deposit contract. Validators are now finalizing data and receiving ether in compensation.

At the moment, validators are only finalizing empty Beacon Chain slots (similar to blocks) and epochs in order to test the stability of the network in mainnet conditions. The Beacon Chain is the heart of the ETH 2.0 system and will be responsible for coordinating the validation of 64 shards once ETH 2.0 is fully launched.

Once ETH 2.0 is fully deployed, the Beacon Chain will finalize the data of 64 shards.

Understanding Phase 1

Now that the Beacon Chain is live, Phase 1 development will focus on launching 64 shard chains. Shards are individual blockchains that ultimately finalize their data and coordinate cross-shard economic activity through the Beacon Chain. One of the purposes of shards in ETH 2.0 is to divide the work of processing and storing transactions in order to scale transaction capacity.  

Initially, all shards will validate empty blocks in order to test the stability of the network in mainnet conditions. Just as in Phase 0, there will be active testnets with clients running shards. 

Numerous testnets preceded the launch of the Beacon Chain. The development of the Beacon Chain involved extensive collaboration between multiple teams and the heavy engagement of the community.

Transferring Economic Activity to ETH 2.0. 

By the end of Phase 2, transactions will be conducted on all shards. Somewhere between Phase 1 and Phase 2, mainnet Ethereum is anticipated to abandon proof-of-work and become the first shard finalizing mainnet Ethereum transaction via proof-of-stake. When this change occurs, over 50 billion USD worth of digital assets will be validated via proof-of-stake. Once cross-chain transactions can be conducted by all shards, lower transaction fees on other shards will likely lead to the migration of some applications over to other shards. 

It is too early to determine how composability will be impacted by a sharded network. One of the factors that makes Ethereum DeFi applications powerful is their ability to easily integrate with one another. Composability will look very different in the event that two DeFi applications published on different shards attempt to interoperate. Although it is too early to provide any definitive analysis concerning what composability on ETH 2.0 will eventually look like, it is worth paying attention to these developments as they happen.  

When fully launched ETH 2.0?

According to the Ethereum Foundation, Phase 1 and the transition of mainnet Ethereum into a proof-of-stake shard is expected to take place by 2021. Considering that Phase 2 is still in the research phase, it is expected to be complete after 2021. 

Although we have provided these dates, they should be treated as soft targets. If ETH 2.0 developers do not feel ready to launch by the end of 2021, expect delays. 


Teamwork Makes the Dream Work

This moment is a culmination of years of work by a multitude of teams and individuals building and coordinating the development of ETH 2.0. Prysmatic Labs, the Teku team by ConsenSys, Sigma Prime, Status, the Ethereum Foundation, Danny Ryan, Justin Drake, Quantstamp, and countless others have contributed to reaching this milestone.

Quantstamp audited two separate ETH 2.0 clients, Teku by ConsenSys and Prysm by Prysmatic Labs. Quantstamp looks forward to continuing working with developers in order to secure Phase 1 and Phase 2 of Ethereum 2.0.

Quantstamp 公告
2020年11月30日

中国北京时间(UTC)12月1日晚12点,烽火链于今日正式上线。11月24日,存款合约达到了524,288乙醚的存款门槛,使得Beacon Chain有资格在7天后推出。自从达到这一门槛后,又有更多的乙醚被存入:截至UTC 12月1日上午8:12,877,249个ETH(价值超过500,000,000美元)被押注在押金合约中。验证者现在正在敲定数据并收到乙醚作为补偿。

目前,验证者只是在敲定空的Beacon Chain插槽(类似于区块)和纪元,以测试网络在主网条件下的稳定性。Beacon Chain是ETH 2.0系统的核心,一旦ETH 2.0全面启动,它将负责协调64个碎片的验证工作。

一旦ETH 2.0全面部署,烽火链将最终完成64个碎片的数据。

了解第1阶段

目前,烽火链已经上线,第一阶段的开发将重点推出64个碎片链。Shards是指各个区块链,最终通过Beacon Chain最终完成数据并协调跨区块的经济活动。在ETH 2.0中,碎片的目的之一是分工处理和存储交易,以扩大交易能力。  

最初,所有的shards将验证空块,以测试网络在主网条件下的稳定性。就像在第0阶段一样,将有运行shards的客户机的活动测试网。 

在推出Beacon Chain之前,有许多测试网。信标链的开发涉及多个团队之间的广泛合作和社区的大量参与。

将经济活动转移到ETH 2.0。 

到第二阶段结束时,交易将在所有的shard上进行。在第一阶段和第二阶段之间的某个阶段,主网Ethereum预计将放弃工作证明,并成为第一个通过股权证明最终完成主网Ethereum交易的shard。当这一变化发生时,价值超过500亿美元的数字资产将通过股权证明进行验证。一旦所有的shard都可以进行跨链交易,其他shard上较低的交易费用将可能导致一些应用迁移到其他shard上。 

现在确定可组成性将如何受到碎片化网络的影响还为时过早。使Ethereum DeFi应用变得强大的因素之一是它们能够轻松地相互集成。在两个发布在不同碎片上的DeFi应用试图进行互操作的情况下,可组合性将看起来非常不同。虽然现在提供任何有关ETH 2.0上的可组合性最终会是什么样子的明确分析还为时过早,但值得关注这些发展的发生。  

当全面启动ETH2.0?

根据Ethereum基金会的说法,第一阶段和主网Ethereum向股权证明碎片的过渡预计将在2021年进行。考虑到第2阶段仍处于研究阶段,预计将在2021年后完成。

虽然我们提供了这些日期,但应将其视为软目标。如果ETH 2.0的开发者觉得还没有准备好在2021年底前推出,预计会有延迟。 


团队合作让梦想成真

这一刻是众多团队和个人多年来构建和协调ETH 2.0开发工作的高潮。Prysmatic Labs、ConsenSys的Teku团队、Sigma Prime、Status、Ethereum基金会、Danny Ryan、Justin Drake、Quantstamp ,以及其他无数人都为达到这个里程碑做出了贡献。

Quantstamp 审核了两个独立的 ETH 2.0 客户端,ConsenSys 的 TekuPrysmatic Labs 的 Prysm。Quantstamp 期待与开发者继续合作,以确保 Ethereum 2.0 的第一阶段和第二阶段。
