title: Hyperledger Fabric, stop parallel chaincode execution
body: <p>all so I have a problem with hyperledger fabric why it is allowed the chaincode to be executed parallel in hyperledger like this:</p>
  
  <pre><code>running push()
  2
  ending push()
  running push()
  1
  ending push()
  running push()
  3
  ending push()
  running push()
  5
  ending push()
  running push()
  4
  ending push()
  </code></pre>
  
  <p>So what I am doing here is:
     - Creating new transaction and sending 2 objects than
     - Immediately sending another transaction </p>
  
  <p>so before the ledger is update the key should be for example: 3 + 2 = 5 and than again 5 + 1 = 6 </p>
  
  <p>but this is wrong in this case because it starts with: 3 + 2 = 5 and before updating the ledger another push is done from the current key 3 + 1 = 4 and not from 5 + 1 = 6.</p>
  
  <p>how can I solve this ?</p>
