**BLockchAiN Contract toolchain**
Welcome to Blanc! Blanc is a toolchain for WebAssembly-based blockchain contracts. Currently, Blanc supports [EOSIO](https://github.com/EOSIO) and [CosmWasm](https://github.com/CosmWasm) (experimental), but we have a plan to support other WebAssembly-based contracts like [Substrate](https://github.com/paritytech/substrate/tree/df501229/frame/contracts). In EOSIO ecosystem, block.one already provides the official version of contract toolchain [eosio.cdt](https://github.com/EOSIO/eosio.cdt), but Blanc takes a different approach from it. eosio.cdt uses the modified version of Clang/LLVM, so you have to wait for block.one's updates to utilize the latest version of Clang/LLVM. Blanc was adapted from eosio.cdt, but uses the vanilla Clang/LLVM for easier maintenance and faster adoption of state-of-the-art technologies. At this point in time (Oct, 2021), eosio.cdt uses Clang-9, but Blanc uses Clang-13. The only thing you need to care about is that your Clang/LLVM installed in your system supports Clang plugins and WASM binary generation. You should have Clang-12 or higher, and in MacOS, you need to install `llvm` by brew. Clang/LLVM installed by Xcode were not built for supporting plugins.
By using the latest Clang/LLVM, generated WASM binaries will have smaller size by about 20%. (eg. `eosio.token` 17KB → 13.5KB, `eosio.system` 305KB → 241KB) All unit tests provided by eosio.cdt and [eosio.contracts](https://github.com/EOSIO/eosio.contracts) are passed and all generated ABIs are identical.
## Nota Bene
We changed branch strategy. The branch for daily development is `master` now, so if you want to build from the source, please use `release` branch for stable version.
## Binary Releases
The prebuilt binares are provided for Ubuntu 20.04 and MacOS Big Sur.
