# fate\_extensions

* Adds new operations to the FATE VM (version 3)
  * bitwise operations on integers (`band`, `bor`, `bxor`, `bnot`, `<<` and `>>`)
  * Address.to\_bytes - converting an address to its binary representation
  * Int.mulmod - a combined multiplication and modulus operation for efficiency
  * Crypto.poseidon - a ZK/SNARK friendly hash function
  * Introduce arbitrary sized binary arrays (type `bytes()`); adding `Bytes.split_any`,`Bytes.to_fixed_size`, `Bytes.to_any_size`, `Bytes.size`, `String.to_bytes`,\
    and `Int.to_bytes`; and adjust `Bytes.concat`, and `Crypto.verify_sig` to allow both\
    fixed and arbitrary sized byte arrays.
  * Chain.network\_id - the network id of the chain
