rbitcoin: Bitcoin Full Node With Zero Human Code | reardencode SLP775

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.
