BitcoinWolfe — free, open source Bitcoin full node in Rust built on libbitcoinkernel. Byte-for-byte consensus compatibility with Bitcoin Core. Full stack: - Consensus: libbitcoinkernel FFI (validates exactly like Core) - P2P: tokio async networking, BIP324 v2 transport - Storage: redb (pure Rust, ACID, zero-copy) - Mempool: configurable policy engine (OP_RETURN limits, fee floors, RBF) - Wallet: BDK 1.1 with PSBT support - Lightning: LDK 0.2 — channels, invoices, payments - Nostr: nostr-sdk — block announcements, fee oracle Your node publishes to Nostr for free: - Block announcements (kind 33333) — height, hash, timestamp, tx count, size - Fee oracle (kind 33334) — mempool fee histogram every 60 seconds And sells data via L402 at 10 sats/request: - /l402/api/block/:height — full block data + txid list - /l402/api/fees — fee histogram - /l402/api/mempool — size, bytes, min fee rate - /l402/api/chain — height, best hash, sync status No API keys. No accounts. Sovereign data from your own consensus engine. https://github.com/refined-element/BitcoinWolfe #bitcoin #lightning #nostr #rust #L402 #opensource
