Enum ergo_lib::chain::address::Address

pub enum Address {
    P2PK(ProveDlog),
    P2S(Vec<u8>),
}

An address is a short string corresponding to some script used to protect a box. Unlike (string-encoded) binary representation of a script, an address has some useful characteristics:

• Integrity of an address could be checked., as it is incorporating a checksum.
• A prefix of address is showing network and an address type.
• An address is using an encoding (namely, Base58) which is avoiding similarly l0Oking characters, friendly to double-clicking and line-breaking in emails.

An address is encoding network type, address type, checksum, and enough information to watch for a particular scripts.

Possible network types are: Mainnet - 0x00 Testnet - 0x10

For an address type, we form content bytes as follows:

P2PK - serialized (compressed) public key P2SH - first 192 bits of the Blake2b256 hash of serialized script bytes P2S - serialized script

Address examples for testnet:

3 - P2PK (3WvsT2Gm4EpsM9Pg18PdY6XyhNNMqXDsvJTbbf6ihLvAmSb7u5RN) ? - P2SH (rbcrmKEYduUvADj9Ts3dSVSG27h54pgrq5fPuwB) ? - P2S (Ms7smJwLGbUAjuWQ)

for mainnet:

9 - P2PK (9fRAWhdxEsTcdb8PhGNrZfwqa65zfkuYHAMmkQLcic1gdLSV5vA) ? - P2SH (8UApt8czfFVuTgQmMwtsRBZ4nfWquNiSwCWUjMg) ? - P2S (4MQyML64GnzMxZgm, BxKBaHkvrTvLZrDcZjcsxsF7aSsrN73ijeFZXtbj4CXZHHcvBtqSxQ)

Prefix byte = network type + address type

checksum = blake2b256(prefix byte ++ content bytes)

address = prefix byte ++ content bytes ++ checksum

Variants

P2PK(ProveDlog)

serialized (compressed) public key

P2S(Vec<u8>)

serialized script

Implementations

impl Address

pub fn p2pk_from_pk_bytes(bytes: &[u8]) -> Result<Address, SerializationError>

Create a P2PK address from serialized PK bytes(EcPoint/GroupElement)

pub fn recreate_from_ergo_tree(tree: &ErgoTree) -> Result<Address, AddressError>

At some point in the past a user entered an address from which the ErgoTree was built. Re-create the address from this ErgoTree. tree - ErgoTree that was created from an Address

pub fn address_type_prefix(&self) -> AddressTypePrefix

address type prefix (for encoding)

pub fn content_bytes(&self) -> Vec<u8>

byte array

pub fn script(&self) -> Result<ErgoTree, SerializationError>

script encoded in the address
