Haskoin Core

Haskoin Core is a library of Bitcoin and Bitcoin Cash functions written in Haskell featuring:

  • Hashing functions (SHA-256, RIPEMD-160)
  • Base58 support
  • CashAddr support
  • Bech32 suport
  • BIP32 extended key derivation and parsing (m/1’/2/3)
  • BIP39 mnemonic keys
  • ECDSA secp256k1 cryptographic primitives
  • Script parsing
  • Building and signing of standard transactions (regular, multisig, p2sh, segwit)
  • Parsing and manipulation of all Bitcoin and Bitcoin Cash protocol messages
  • Bloom filters and partial merkle trees (used in SPV wallets)
  • Comprehensive test suite
