I guess math without coding, around decentralized tech is probably about statistical analysis of how systems are working now and improve. Trying to contribute to decentralization. Also cryptography is applicable. Trying to improve security of things. Carefully studying cashu maybe regarding the cryptographic nature of it or general security of it since it is a new thing?

Maybe ideas around how nostr may fail? Centralization, lack of adoption, secret key management issues, how to include most "useful" notes and exclude the harrassment at the same time .. .
