Interesting comment by Peter Todd when discussing the possible use of nostr as a new protocol for the bitcoin-dev mailing list. His comments are not particular to that usage though:

"

Strong NACK on nostr. It's a badly designed, centralized, protocol that needs a

significant redesign to be usable. While off topic for this mailing list, some

of its many issues include:

* Reliance on single-key, cryptography that often results in people having

their keys compromised. This is a serious problem in the context of

bitcoin-dev, where faked messages published could easily have market-moving

results.

* Inability to mirror relays: since nostr deliberately ignores the lessons of

blockchains, there is no way to be sure that you have a complete set of

messages from a given person, for a given topic, etc.

* Highly centralized design: since mirroring relays isn't reliable, in reality

nostr operates in a highly centralized fashion, dependent on a tiny number of

relays that can't be easily replaced if taken down.
