eth2.0是什么意思？ETH2.0上线时间确定没？

看到这个问题，相信很多投资者是一脸蒙圈的，主要是因为大多数投资者对于ETH是了解，毕竟市面上投资ETH的人不少，但是对于ETH2.0，很多投资者都是模糊不清的，甚至对于很多开发者来说，ETH2.0也不够清晰，而对于ETH2.0币圈给其的定义是作为未来的以太坊替代品，那么，eth2.0到底是什么意思呢？下面币圈子小编就给大家通俗的讲解一下eth2.0是什么意思？希望通过本文的讲解投资者对于ETH2.0有最基础的认知。

Seeing this problem, it is believed that many investors are masked, mainly because most investors know about ETH. After all, there are a lot of people who invest in ETH, but many investors are vague about ETH 2.0, and even for many developers, ETH 2.0 is not clear enough, and ETH 2.0 is defined as a future Ethium substitute. So what does Eth 2.0 mean?

ETH2.0就是一个可扩展的权益证明基础设施。在2019年的12月8日，以太坊完成了伊斯坦布尔硬分叉，此次分叉降低了以太坊的GAS费成本，同时将承载从几十提升至3000，这意味着大都会时期的结束。并且正式迎来了ETH1.0与ETH2.0的过渡时期。

ETH 2.0 is an extended equity proof infrastructure. On December 8, 2019, Etheria completed the Istanbul hard split, which reduced the cost of its GAS and raised the load from dozens to 3,000, which means the end of the Metropolis period.

大家都知道2.0升级会将POW挖矿转为POS，但实际上整个升级过程的初期阶段是双链并存的状态，会同时存在现在的主链(原始链)和新链(POS机制)，以及两种代币ETH1.0和ETH2.0。这期间用户可以将ETH1.0烧掉，以换取ETH2.0，但是ETH2.0将被有效冻结，直到2.0的全面升级完成(到时候我们可以看到交易所同时交易两种以太坊代币的有趣现象)。也就是说，在整个2.0的过渡期，都要保障原始链的可操作状态。这也是问题所在：升级过程需要同时维护和开发两条链，并实现分片等关键技术突破，相比其他公链的主网直接切换，凭空多出一条链的工作量。

While it is well known that the 2.0 upgrade will convert Pow digs into POS, the initial phase of the whole upgrading process is in a dual-chain state, with the present main chain (the original chain) and the new chain (the POS mechanism), as well as two ETH1.0 and ETH 2.0. During this period, users can burn ETH1.0 in exchange for ETH 2.0, but ETH 2.0 will be effectively frozen until the full 2.0 upgrade is completed (when we can see the interesting fact that the exchange is trading in both of these currencies). That is, throughout the 2.0 transition period, the operational status of the original chain will be safeguarded.

至于双链并存的这个中间状态，需要持续多久，我们可以从官方最新博客文章推断。据发布的《1.x文件：快速同步》描述，开发团队现在专注于对以太坊1.x进行更多增量升级，并表示需要将“以太坊原始链的寿命至少再延长3-5年”。理论上，原始链需要维护的时长就是中间状态，2.0一旦升级完成原始链就完成了历史使命，故可以推断，官方预计整个2.0的升级过程至少需要3-5年。之所以需要这么久，一个重要原因是原始链上目前仍然存在一些核心问题需要解决，包括链存储、区块大小和交易吞吐量及状态大小和网络性能，必须要保证双链都达标才能顺利完成升级。

As the release of Document 1.x: Rapid Synchronization describes, the development team is now focusing on more incremental upgrades to Ether's 1.x and the need to extend “ extend the life of the Ether's original chain for at least three to five more years & & rdquo; theoretically, the original chain will have to be maintained for an intermediate period, while 2.0 completes its historical mission once the original chain has been upgraded, so it can be deduced that the official projection of the entire 2.0 upgrading process will take at least three to five years. One important reason for this time is that there are still core issues on the original chain that need to be addressed, including chain storage, block size, transaction size, and state size and network performance.

总之官方博客文章给我们传递的信号是，以太坊2.0的完成还需要很久，3-5年是现在预测的保守时间。那么这期间价格、2.0的完成时间，都充满了不确定性。以太坊基金会的研究员丹尼·瑞安曾在媒体采访中表示2020年一季度是2.0零阶段开始的暂定日期，会如期到来吗?另外2.0的零阶段，会引入staking，也就是现在的ETH可以转换成锁定的ETH2.0，到时候两种代币价格是多少?大家是否会买入ETH1.0去燃烧为ETH2.0进行锁仓从而造成通缩，带来新一轮炒作?这些都是目前加密史上未曾出现的事情。

In any case, the official blog post sends us a signal that the completion of the Taiyo 2.0 will take a long time, and that three to five years is now the conservative time forecast. So the price, the time of completion of 2.0, is full of uncertainty.

2020年11月4日，以太坊基金会在官方博客表示，已经发布以太坊2.0规范v1.0，其中包括以太坊2.0主网存款合约地址0x00000000219ab540356cbb839cbe05303d7705fa。以太坊2.0阶段0将在Unix时间戳1606824000创世，UTC时间为2020年12月1日。

On November 4th, 2020, the ETA Foundation announced on its official blog that it had published the ETA 2.0 regulation v1.0, including the ETA 2.0 capital deposit contract at 0x0000002ab5419b540356cbb839cbe050303d7705fa. The ETA 2.0 phase 0 will mark the creation of 1606824000 at Unix time and UTC on December 1st, 2020.

要触发创世，必须在12月1日前7天至少有16384个验证者存款(每个验证者32枚ETH，总计524288枚ETH)。如果没有，则将在达到这一门槛后(无论何时)7天触发创世。

In order to trigger the creation, there must be at least 16384 Certifying Officers deposits (32 ETHs per Certifying Officer, for a total of 524288 ETHs) seven days before 1 December. If not, it will trigger the creation seven days after the threshold has been reached.

这一声明标志着在经过多年的期待和延迟之后，以太坊2.0发布的确定日期首次确定了。

This statement marks the first time that, after many years of anticipation and delay, a firm date has been set for its release in Taiyeon 2.0.

一旦推出，以太坊2.0将成为测试Proof-of-Stake共(PoS)识算法系统的试验网。大部分经济活动和智能合约将继续在原有的以太坊网络上运行，它将继续成为以太坊2.0的平行系统。开发者实现了Eth1向Eth2过渡的连接桥，但反向是无法转回Token的。

Once launched, Ether 2.0 will be a test network for testing Proof-of-Stake (PoS) algorithms. Most economic activities and smart contracts will continue to run on the old Ethernet network, and it will continue to be the Ether 2.0 parallel system.

通过以上介绍，相信大家对于eth2.0是什么意思这个问题已经有所了解，最后，币圈子小编给大家总结一下ETH2.0，其实ETH2.0是跟以太坊完全不同的系统，它们将并行多年，且有非常不同的功能，在不久的将来，预计会有一个从ETH到BETH的单向锚定，若是运行交易所或托管服务，考虑一下，在它可进行链上转账之前，你如何能为用户提供支持BETH托管交易和权益服务。

As a result of these presentations, it is believed that there is already some understanding of what Eth 2.0 means. Finally, the currency circle summarizes ETH 2.0, which is a system that is completely different from that of Ether, which will last several years and have very different functions. In the near future, it is expected that there will be a one-way anchoring from ETH to BTH, and in the case of an exchange or hosting service, consider how you can support the user of BITH hosting transactions and equity services before it can be transferred on the chain.
