Abstract

This document describes the specification of KSChain DID.

This is a draft document and will be updated.

Blockchain-Based Identifier (KSChain)

The name string that identifiers this DID method is kscirc .

1. KSChain DID Format

kschain-did       = "did:kscirc:" + [specific-idstring]
specific-idstring = "k" + [base58-encoded-id]
base58-encoded-id = Base58-Encode(Version + Identifier + CRC)

• “k” (in specific-idstring) is prefix.
• “Version” means information of version. In the current version, this value is 0x00.
• “Identifier” is the result of performing an arbtirary shuffling function on the output value of Block Cipher(e.g. AES-256).
• “CRC” means has value of the first 4 bytes of the public key. In this specification, the hash algorithm uses SHA3-256.
• The length of “specific-idstring” is 52~53.
