Documentation
Check out the beginnings of the documentation for the library: [Introduction]
Presently supported:
- Blocks, headers, and merkle blocks and bloom filters
- P2SH & Segregated witness scripts
- An adaptable elliptic-curve library, using [PhpEcc] by default, or libsecp256k1 if the bindings are found
- Support for building, parsing, signing/validating transactions
- Deterministic signatures (RFC6979)
- BIP32 and electrum (older type I) deterministic key algorithms
- BIP39, and the older electrum seed format.
- ScriptFactory for common input/output types, parser, interpreter, and classifiers
- Supports bindings to libbitcoinconsensus
- Bindings to Stratum (electrum) servers
