+# Rust-BCH
+
+A fresh library to build Bitcoin Cash applications in Rust.
+
+Features
+
+* P2P protocol messages (construction and serialization)
+* Address generation (cashaddr and legacy)
+* Transaction signing
+* Script evaluation
+* Node connections and basic message handling
+* Wallet key derivation and mnemonic parsing
+* Mainnet and testnet support
+* Various Bitcoin primitives
+
+# Requirements
+
+Rust nightly is required for documentation due to a bug fix which has not yet made it to stable.
+
+Run ./configure once to setup nightly.
+
+# Known limitations
+
+This library should not be used for consensus code because its validation checks are incomplete.
+
+# Comparison with other Rust libraries
+
+*rust-bitcoin* - rust-bch has no ties to rust-bitcoin. This library can do everything rust-bitcoin can do and more for Bitcoin Cash.
+
+*parity-bitcoin* - The parity Bitcoin client is a full node in Rust. Its code is more full-featured and also more complex.
+
+*bitcrust* - The bitcrust project is strong in some areas and lacking in others. The two projects could be used together.
+
+# Support for the November 2018 hard fork
+
+This library supports the SV implementation of Bitcoin Cash. It includes the new opcodes OP_MUL, OP_RSHIFT, OP_LSHIFT, and OP_INVERT and the increased script op limit. CDS and CTOR validation are not supported.
+
+# License
+
+rust-bch is licensed under the MIT license.
