Nostr 文档列举的长毛象的问题

User identities are attached to domain names controlled by third-parties;

Server owners can ban you, just like Twitter; Server owners can also block other servers;

Migration between servers is an afterthought and can only be accomplished if servers cooperate. It doesn't work in an adversarial environment (all followers are lost);

It doesn't make sense to have a ton of servers if updates from every server will have to be painfully pushed (and saved!) to a ton of other servers. This point is exacerbated by the fact that servers tend to exist in huge numbers, therefore more data has to be passed to more places more often;

前三个问题本质上是一个问题，Nostr 用公钥制解决了。

最后一个问题，Nostr 用不互相通信的中继解决，而不是像长毛象服务器之间互相通信，一种联邦制。
