Today, Jack Dorsey, donated 14BTC (~$250,000) to the developers of the nostr protocol.
From their Github repo[0]:
The simplest open protocol that is able to create a censorship-resistant global "social" network once and for all.
It doesn't rely on any trusted central server, hence it is resilient; it is based on cryptographic keys and signatures, so it is tamperproof; it does not rely on P2P techniques, therefore it works.
