# Module `0x1::bcs`
Utility for converting a Move value to its binary representation in BCS (Binary Canonical
Serialization). BCS is the binary encoding for Move resources and other non-module values
published on-chain. See https://github.com/diem/bcs#binary-canonical-serialization-bcs for more
details on BCS.
