Request
Path Parameters
- timestampId
Multihash of the sha256 of the original hash, encoded in multibase base64url.
timestampId = multibase_base64url(multihash(sha256(original_hash)))
Example: let's assume the original hash is a sha3-224 with the value
0xb2a8e000d1f25778cecf6b29fc0e7f811fb5f4a3a8230585e9056921
It is stored in the smart contract with the timestamp ID
0xb2a8e000d1f25778cecf6b29fc0e7f811fb5f4a3a8230585e9056921
The multihash representation of
0xb2a8e000d1f25778cecf6b29fc0e7f811fb5f4a3a8230585e9056921
EiCPQS4deZG8y1FXlG9sW1vDfMbpulXYTkn0HWj2OWd61A
At the API-level, the timestamp ID is then
uEiCPQS4deZG8y1FXlG9sW1vDfMbpulXYTkn0HWj2OWd61A
Description: Valid Pilot timestampId
Example: uEiCyzskEVXTNJVok_wI3wHty3LIJ3Apz_4HDocgAUtKGjg
