当我意识到新交易类型能多快被添加进来时，我也转而同意 Gavin 的白名单主张了。
I came to agree with Gavin about whitelisting when I realized how quickly new transaction types can be added.
其他参与者原话nanotube原帖 ↗为什么不让大家省点事，直接允许交易里携带比如 64 或 128 字节的随机数据呢？
why not make it easier on everyone and just allow say, 64 or 128 bytes of random data in a transaction?
这已经可行了。
That's already possible.
我也支持增加第三种交易类型，承载时间戳哈希大小的任意数据。反正现在已经能做到，不提供反而不合理。它还可以告诉节点：不必费心为它建索引。
I also support a third transaction type for timestamp hash sized arbitrary data. There's no point not having one since you can already do it anyway. It would tell nodes they don't need to bother to index it.
