Token ID

Token ID is a byte array calculated as follows:

• If the token is issued by Issue transaction, the token ID is the same as the transaction ID.
• If the token is issued by Invoke Script transaction when the callable function of dApp script performed the Issue action, the token ID is calculated as the BLAKE2b-256 hash of the byte array containing transaction ID and the fields of the Issue structure.

In the Node REST API, the token identifier is encoded in base58 (opens new window). For example:

 "assetId": "8LQW8f7P5d5PZM7GtZEBgaqRPGSzS3DfPuiXrURJ4AJS"

The WAVES token has no identifier. The Node REST API uses null for WAVES.
