When transferring CCC or assets, the sender must know the recipient's lock script hash and parameters. An address is a converted form of the lock script hash and parameters, and it has some benefits.

  • An address includes a checksum. There is a high probability that a mistyped address is invalid.
  • An address is case-insensitive alphanumeric, which is easy to speak aloud or type on the mobile phone. It also makes it efficient to generate QR codes.

Bech32

CodeChain adopted Bitcoin's Bech32 Specification. The differences from Bitcoin are the following:

  • CodeChain has no separator.
  • CodeChain has 2 types of address. One is for CCCs and the other is for assets. They are distinguished by HRP(Human Readable Part)

Address formats are not a core part.

1. Platform Account Address Format

HRP: "ccc" for Mainnet, "tcc" for Testnet.

Data Part: version . body

Version 0 (0x00)

No longer available. Any version 0 address will be rejected in the latest clients.

Version 1 (0x01)

Data body: Account ID (20 bytes)

Account ID is the result of blake160 over a public key(64 bytes uncompressed form).

2. Asset Transfer Address Format

HRP: "cca" for Mainnet, "tca" for Testnet.

Data: version . body

Version 0 (0x00)

No longer available. Any version 0 address will be rejected in the latest clients.

Version 1 (0x01)

Data body: type . payload

Type 0 (0x00)

Payload: <LockScriptHash> (20 bytes)

Type 0 with given payload represents:

  • Lock Script Hash: <LockScriptHash>
  • Parameters: []

Type 1 (0x01)

Payload: <Public Key Hash> (20 bytes)

Type 1 with the given payload represents:

  • Lock Script Hash: P2PKH Standard Script Hash (5f5960a7bca6ceeeb0c97bc717562914e7a1de04)
  • Parameters: [<Public Key Hash>]

Type 2 (0x02)

Payload: <Public Key Hash> (20 bytes)

Type 2 with the given payload represents:

  • Lock Script Hash: P2PKHBurn Standard Script Hash (37572bdcc22d39a59c0d12d301f6271ba3fdd451)
