bitcoin++ privacy edition | Riga, Latvia | Day 1
summary
Lightning privacy progress: Bolt12 blinded paths and invoice/onion messaging solve sender/receiver anonymity but only ~5–6% of nodes forward onion messages today; timing attacks show a central node sees ~37% of payments and four colluding nodes see ~72%; Revelio-style AS-level analysis finds the top five AS observe ~80% of channels (AWS ~34%) and reports ~32% deanonymization. Other sessions show a working UTXO Oracle demo (on-node onchain price extraction), an RPKI 60% / Europe 98% / US 44% adoption snapshot and an asmap workflow, MLS/Nostr groups being implemented for large private messaging, credential designs for Cashu, and empirical coinjoin failure rates that drop below 20% at ~400–500 participants.
