bitcoin++ privacy edition | Riga, Latvia | Day 2
summary
Wasabi’s coinjoin decomposes amounts — one demo shows a 516,000 satoshi input split into three outputs and an on‑chain round that looks like 214 inputs 255 outputs, with Wasabi computing anonymity set scores and warning about address‑reuse leaks. El Tor embeds Lightning offers into Tor descriptors and runs 10‑round Tor circuits with per‑minute Lightning payments and optional handshake fees (Chutney testnet and ltord released). Other specifics: PayJoin reduces on‑chain footprint to scale privacy, CISA proposes cross‑input signature aggregation for big coinjoins, and GitFuzz wins the hackathon.
