TFTC: A Bitcoin Podcast
#155: Openoms
- OpenOMS's journey into Bitcoin starting in 2013, leading to full-node operation and tutorial building around 2017–2018, especially after discovering the RaspiBitStack project.
- JoinInbox hardware and JoinMarket's decentralized CoinJoin implementation: no central coordinator, maker/taker fee incentives, five-account wallet structure with privacy-preserving mixing across accounts.
- Fidelity bonds as a novel anti-Sybil mechanism in JoinMarket that increases attack cost by requiring locked UTXOs, boosting skin-in-the-game for liquidity providers.
- Privacy on the Lightning Network across three dimensions: sender privacy (already strong unless all hops are controlled), receiver privacy (weak; invoices expose public keys and route details), and network-level privacy via Tor.
- Receiver privacy mitigations including Phoenix's trampoline routing and fake channel IDs, plus user practices like splitting withdrawals across intermediate mobile wallets before final self-custody transfer.
- The importance of running Bitcoin and Lightning nodes on dedicated hardware behind Tor to prevent IP-address linkage, especially for routing nodes holding significant liquidity.
