Associated Type: Hash

NOT part of the Activity Streams 2.0 Vocabulary.

Activity objects linking to external content such as audio, image or video files must include a "hash" field for users to validate linked content. The value of this "hash" field must be an array of strings. Each item in the array MUST be a valid DSNP Content Hash for the content associated with the hash.

Example

This example gives SHA-256 and BLAKE3 hashes for the PDF version of the DSNP whitepaper.

{
  "hash": [
    "bciqdnu347gcfmxzbkhgoubiobphm6readngitfywktdtbdocgogop2q",
    "bdyqhwoxp2mc6oyaqpqyd2fvaxralslk32ggazv6nxpp342iec6652tq"
  ]
}
