Create Link Record §

  1. The record owner selects any encoders and salt to use

  2. The record owner creates an encoded link record via Event

  3. Event encodes the record as specified to produce a fingerprint

  4. The linked fingerprint is written to the blockchain

  5. The result is the fingerprint and its link location on the blockchain

  6. The record owner stores the salt, fingerprint and location for later processing

Example code:

curl -X POST "$URL/api/v1/linkedrecords?encode=SHA256(01-02T13.14.15)|Base64" \
     -H "x-api-key: $KEY" \
     -H "Content-Type: application/octet-stream" \
     --data-binary "hello"

Example cURL response:

{
  "txId": "4f170a122b82783d....43d2b5d99d3ed190d0b",
  "encoding" : [ 
    { "content-type": "…|Base64", "output" : "ytfc5c5wv0V7hOo....G1ucRFzSIe6rw=" }
  ]
  ...
}

The final "output" shows the record that was written to the blockchain.

  1. The record owner creates a record via Event

  2. The result is the link location of the record on the blockchain

  3. The record owner stores the link location for later processing

  4. Ideally, the record owner should check the link location status

Example code:

curl -X POST $URL/api/v1/linkedrecords \
     -H "x-api-key: $KEY" \
     -H "accept: text/plain" \
     -H "Content-Type: application/octet-stream" \
     --data-binary "hello"

Example cURL response:

{
  "txId": "47175b2ee3345942….d58cd286198e1bc97",
  ...
}

Extract Location

At least the location (shown as "txId") should be stored for subsequent operations:

LOC=47175b2ee3345942....d58cd286198e1bcf97
