At the end of the vote, either success or failed, we can have old TXs work again. It’s like after a long time that the block jammed. I think nobody get harmed (Is there? I’m not so sure about that), that’s the purpose.
I think that would cause problems with systems like lightning network
that rely on reliable confirmations of transactions as part of their
security models.

>>
>> 鉴于最初的比特币协议并未考虑不参与挖矿的钱包节点，导致这些钱包节点的协议升级是被动的，懒惰的。当在升级方向上出现分歧时，矿工也不愿意在错误的链上挖矿，但矿工又没有任何方法可以确保正在延长的链是被钱包节点广泛接受的链。这将影响钱包节点的安全。<br/>

>>
>> 使用该方法可以在保证钱包节点资产安全的情况下，且通过增加激励让钱包节点升级协议。一旦钱包节点升级协议，保证矿工节点不仅工作在算力最长链上，还工作在比特币生态环境中其他钱包节点所使用的最长链上。在中本聪共识下不会出现分叉，以实现渐进式的协议升级。<br/>
>>
>> Apart from ensuring the asset security of wallet nodes, this method can be used to provide additional incentives to upgrade the protocol for the wallet nodes. Once the wallet nodes upgrade their protocol, the miners' nodes can be guaranteed to work - not only on the longest chain, but also on the longest chain used by other wallet nodes in the broader bitcoin sphere. Under the Nakamoto Consensus, there will be no persistent forks as protocol upgrades can be phased in.<br/>

>> 3. 钱包节点升级。在挖矿节点监测到第二个宽限期 4032 个连续的新版本的区块后，开始拒绝旧版本号的交易，只打包／转播新版本号的交易。同时将从内存池中删除旧版本号的交易。<br/>
>> 4. （可选的）协议升级。在第三阶段中包含有第四阶段的升级代码。当我们确保钱包节点升级到支持新版本交易后，必然包含了第四阶段的升级代码。则此时可以通过矿工节点投票的方式完成全网络的协议升级。

>>
>> 2. Mining nodes upgrade stage: After a first grace period of 2016 blocks and total signalling blocks passed 2218 of 4032 blocks, miners broadcasting blocks with new versionbits in block headers will orphan blocks with old versionbits.

>>
>> 3. Non-mining nodes upgrade stage: after 4032 continuous blocks with new versionbits, mining nodes will start to refuse transactions with old versionbits.

>>
>> 4. (Optional)Protocol Upgrade stage: The codes dealing with protocol upgrade can be integrated in the third stage.

>> ==Benefits==
>>
>> 1. 仅需要多数的矿工发信号后即可激活。在中本聪的比特币论文中，99.9% 的可能性下，55% 的矿工将在 340 个区块后确保成为最长链。这将最大可能减小通过控制少数算力而拖延网络升级的可能性。我们可以预见到在算力信号超过 51% 后，挖矿节点将迅速的在第一个宽限期内进行升级。<br/>
>> 2. 在两个宽限期内，钱包节点交易不受影响，有足够的时间升级钱包软件。<br/>
>> 3. 版本信息包含在 block header 中，并不影响 SPV 挖矿过程。（看起来是？）<br/>
>> 4. 在两个宽限期后，钱包节点将必须升级钱包，否则因没有算力支持将无法发送交易，也无法确认。相对于在节点间重新达成新的共识，这种状况并没有更糟糕。<br/>
>> 5. 钱包节点的账本将得到尊重和保护。使用链下钱包的用户将需要在钱包服务提供商的声明之后决定提至链上钱包或跟随。<br/>
>> 6. 将来的协议升级，可以在升级客户端版本同时绑定协议升级代码并进行独立的激活投票。这将预留足够的时间让节点升级软件以支持新的协议。即使矿工投票激活失败也不影响现状。<br/>
>>
>> 1. The activation only requires majority miners signal. As described in the paper by Satoshi Nakamoto, 55% miners will be in the longest chain after 340 blocks, with 99.9% certainty. This will minimize the possibility of delaying network upgrades by controlling a small number of hashing power. We can foresee that after 51% signalling, all miners will upgrade within the first grace period. <br/>
>> 2. During the first two grace periods, non-mining nodes will not be affected. They have enough time to upgrade their software. <br/>
>> 3. Versionbits included in block header, not influencing the SPY mining. <br/>
>> 4. After two grace periods, all nodes must be upgraded. Otherwise they cannot send transactions or get any confirmations. Compared with forming new consensus among nodes, the situation is not worse than before. <br/>
>> 5. The ledger in non-mining wallet nodes is honored and reserved. Users of off-chain wallet services can decide whether or not to follow the service providers after they got the public notification from the service providers. <br/>
>> 6. Protocol upgrades in the future can be bonded with the upgrades of nodes, and the upgrades activate through miners vote independently. There would be enough time for nodes to be upgraded in order to support new protocols. Even in case of failing in miner activation, the situation will not worsen and the status quo will remain. <br/>
>>
>>
>> ==Risks==
>>
>> 1. 算力的波动会影响最长链的结果。因此越高的激活比例要求将减少短时间分叉的危险。<br/>
>> 2. 矿工可能发假信号来避免被孤立，但在钱包节点看来无法区分是否是假信号，只能升级。而钱包节点升级之后，矿工也将跟随。<br/>
>> 3. 钱包节点可能发假信号来仅升级版本号而不支持绑定的协议升级代码，但钱包节点数量无法判别，严肃的真实节点应当跟随可证实的矿工投票结果。<br/>
>> 4. 存在少部分矿工和钱包节点共谋，在新协议升级激活后依然使用老协议挖矿的可能。这种可能随时发生无法杜绝，但通过让沉默的大多数钱包节点升级的方式可以降低这种行为带来的利益。<br/>
>>
>> 1. The fluctuation of the hashing power will affect the result of the longest chain. Higher activating requirement means a lower risk of temporary fork. <br/>
>> 2. Miners could simply signal to avoid being orphaned, but from the perspective of non-mining wallet nodes, they can't distinguish the false signal from the true signal. They must upgrade with the assumption that the signals are all true. After all the non-mining nodes have upgraded, the miners signalling false signal should follow. <br/>
>> 3. Non-mining wallet nodes could false signal without supporting the new protocol but since the total number of nodes cannot be distinguished, genuine nodes should follow the proven result provided by miners vote. <br/>
>> 4. Miners and non-mining nodes could conspire to fork using old protocol consensus. It can't be eliminated, just like in the past but through most passive non-mining nodes being upgraded, their benefit is reduced. <br/>
