类名称：Transaction
方法名：isFinal

Transaction.isFinal介绍

[英]Returns true if this transaction is considered finalized and can be placed in a block. Non-finalized transactions won't be included by miners and can be replaced with newer versions using sequence numbers. This is useful in certain types of contracts, such as micropayment channels.

Note that currently the replacement feature is disabled in Bitcoin Core and will need to be re-activated before this functionality is useful.
[中]如果此事务被视为已完成且可以放置在块中，则返回true。矿工不包括未完成的交易，可以用使用序列号的更新版本替换。这在某些类型的contracts中很有用，例如小额支付渠道。
请注意，比特币核心中的替换功能目前已禁用，需要重新激活才能使用该功能。
