rbitcoin: Bitcoin Full Node With Zero Human Code | reardencode SLP775
Om avsnittet
Almost every public Bitcoin node still runs Bitcoin Core. Brandon Black argues that client monoculture is a systemic risk — and that automation plus AI now make independent consensus implementations more realistic than skeptics assume.
Brandon (aka reardencode) returns to Stephan Livera Podcast for the first episode in a mini-series on non-Core Bitcoin implementations. He is shipping rbitcoin, a Rust full node aimed at server-side wallet and Lightning backends, with Electrum served in-process.
They dig into why rbitcoin has no UTXO set and no Core-style dbcache, how build-time differential testing differs from satd’s in-process libbitcoinconsensus dual-eval, BIP324 v2-only P2P, archival storage tradeoffs, LibreRelay-inspired policy, and what “production-ready™” means when every first-party line was written by AI under his prompting.
Brandon is blunt about maturity: the project is still early, contributors are welcome at rbitcoin.org, and listeners should treat alt clients as high-scrutiny infrastructure — not a drop-in replacement for Core tomorrow.
