Functions

func ChunkifyCode

func ChunkifyCode(code []byte) []byte

ChunkifyCode generates the chunked version of an array representing EVM bytecode

func GetTreeKey

func GetTreeKey(address []byte, treeIndex *uint256.Int, subIndex byte) []byte

GetTreeKey performs both the work of the spec's get_tree_key function, and that of pedersen_hash: it builds the polynomial in pedersen_hash without having to create a mostly zero-filled buffer and "type cast" it to a 128-long 16-byte array. Since at most the first 5 coefficients of the polynomial will be non-zero, these 5 coefficients are created directly.
