LEB128

Little Endian Base 128 encoding for unsigned integers typically used to specify length prefifixes for arrays and strings. Values in range [0, 127] are encoded in one byte. Larger values use two or more bytes.

Integer

A LEB128 integer with a maximum allowed value of 0x7fffffffffffffff (2 – 1) and a minimum of 0. A varint63 ifts into a signed 64-bit integer.

String

A binary string with a LEB128 prefifix specifying its length in bytes. The maximum allowed length of the underlying string is 0x7fffffff (2 – 1).

The empty string is encoded as a single byte 0x00, a one-byte string is encoded with two bytes 0x01 0xNN, a two-byte string is 0x02 0xNN 0xMM, etc

String32

A fixed-length 32-byte string typically used to encode hashes.

SHA3

SHA3 refers to the SHA3-256 function as defined in FIPS202 with a fixed-length 32-byte output. This hash function is used throughout all data structures and algorithms in this spec, with the exception of SHA-512 (see FIPS180) used internally as function H inside Ed25519 (see RFC8032).

List

A List is encoded as a Integer-prefixed list of serialized items, one by one, as defined by the schema. The length preiifx indicates the number of items that follow.

Struct

A Struct is encoded as a concatenation of all its serialized fifields.

Public Key

In this document, a public key is the 32-byte binary encoding of an Ed25519 (EdDSA) public key, as defined in RFC8032.

Signature

In this document, a signature is the 64-byte binary encoding of an Ed25519 (EdDSA) signature, as defined in RFC8032

Signature

Auxiliary data structures are Structs that are not entries by themselves, but used as fields within the entries.

Pointer

A Pointer is encoded as a String32, and identifies another entry by its ID. Pointer restricts the possible acceptable types: Pointer must refer to an entry of type X. A Pointer can be nil (not pointing to any entry), in which case it is represented by the all-zero 32-byte hash:

0x0000000000000000000000000000000000000000000000000000000000000000

Program

Program encapsulates the version of the ACI GOLD and the bytecode that should be executed by that ACI GOLD

Inputs

1. Programs,

2. Arguments (list of strings),

3. Transaction version (integer).
