我经常看到一般的经验法则是30次确认.这是否足够,还是可以计算900笔背书,还是使用其他更复杂的方法来确定对交易终结的信心?

I have often seen the general rule of thumb be 30 block confirmations. Is this adequate or is it better to count to 900 endorsements or use some other more complicated approach to determining confidence in the finality of a transaction?

使用健身/背书更好(尽管更复杂).900笔健身/签注大约是30个"正常"区块(即具有接近完整签注的区块),这是用户记住和检查的更简单的经验法则.

区别在于,如果过去30个区块的认可度/适应性很低-则过去进行链式拆分的可能性更高.我认为,仅在" 30个街区"之后进行确认的风险就更大.

如果您可以监控健身/背书之间的差异,我会使用它.

It is better (although more complex) to use fitness/endorsements. 900 fitness/endorsements is roughly 30 "normal" blocks (i.e. blocks with close to full endorsements), which is a simpler rule of thumb for users to remember and check.

The difference would be if the past 30 blocks have very low endorsements/fitness - this would make a chain-split in the past a higher probability. Confirming after just "30 blocks" is more riskier in my opinion.

If you can monitor the fitness/endorsement difference, I would use that.

Tezos当前协议(003)实现概率确定性在建议的30次确认时间之后,这减少了交易受到重组影响的机会.

有对话关于借助BFT类型的机制,例如嫩薄荷

编辑20190328:现在正式由 Cryptium Labs 为tezos实施招标薄荷为此获得了 Tezos基金会补助.

Tezos current protocol (003) achieves probabilistic finality after a recommended time of 30 confirmations which reduces the chances of the transaction being impacted by a reorg.

There are conversations about the possibility to evolve the consensus in the future to achieve absolute finality in 1 block time with a BFT type of mechanism such as tendermint

EDIT 20190328: it is now official that tendermint will be implemented for tezos by Cryptium Labs who has received a Tezos Foundation grant for it.
