Bitcoin Validation Without a Node: A Practical Introduction to libbitcoinkernel
summary
libbitcoinkernel exposes Bitcoin Core’s validation engine as a reusable C API with Python bindings and Rust/Go bindings, letting code parse raw hex into opaque block/tx objects, run a context-free check (merkle + proof-of-work), execute script verification given a coin amount, and run full chain-backed validation via a chain manager that builds a UTXO DB, fires callbacks on connect/disconnect, and handles reorgs. API is experimental, missing some introspection (input scripts/witness) and fine-grained error reasons.
