title: Hyperledger Fabric - How to Decode data_hash to return the actual data?
body: <p>I have been involved in developing Blockchain application using hyperledger fabric.</p>
  
  <p>I made use of <strong><em>fabric-node-sdk</em></strong> to interact with blockchain layer.</p>
  
  <p>Right now I have few data that were inserted into blocks &amp; we are able to see them in CouchDB &amp; query the same to retrieve data.</p>
  
  <p>When <strong>channel.queryBlock(1)</strong> is called we get <strong>data_hash</strong> as its response, Is there a way to <strong><em>decode data_hash</em></strong> to get the actual data ?</p>
  
  <p>The data_hash would look like this : 0dafabc38a7d216426b9a9ab71057fe6c8b984c9e44f92b7265fbd3e2785e26c</p>
  
  <p>Any suggestion would be a helpful.</p>
  
  <p>Thank You!</p>
