How about using Nostr to relay Bitcoin transactions of other users!
I feel like we had a conversation at #[0]'s pod about this just last week and now there is a proposal for a Bicoin transaction relay over nostr by #[1] 🤙
The speed at which things are happening!
Why is this important?
Bitcoin nodes send transactions to their peers which then are propagated further to the rest of the network. Surveillance companies connect to *many* nodes so they can estimate the origin of a transaction, which can potentially be used to link your Bitcoin wallets to your real-life identity (through your IP address). If you're paranoid, you can use mempool dot space already today to publish your transactions as an alternative to the P2P network.
But having a network of different users all broadcasting each other's tx, like with this proposal, is a lot more powerful IMO. Whether this or something like this ever makes it into Bitcoin Core remains to be seen. Usually it takes a ton of work. But what's for sure is that alternatives to the normal P2P relay are urgently needed. Proposals like Dandelion are cool but apparently prone to DoS attacks.
Wonder whether we'll ever see a synergy between Bitcoin Core and Nostr. This is an excellent first step in that direction.
