Define the blockchain endpoint to use as an ENV variable:

export BLOCKCHAIN_ENDPOINT=https://node.blockchain-service.com

API

Example usage:

  const pathToKey = "./KEY.priv.key";
  const blockContent = "TEST FROM BACKEND";

  const signedBlock = await clientSign(
    "NOTARIO", // ENTITY
    "NOTARIO", // SCOPE
    blockContent, // BLOCK CONTENT
    pathToKey // PATH TO LOCAL KEY
  );

  const submitResult = await submitBlock(signedBlock);
  console.log("submitResult", submitResult);
  console.log(await confirmBlock(signedBlock.hash));

Example result:

submitResult { verified: true, queued: true }
