title: Endorsement System Chaincode (ESCC) in Hyperledger Composer
body: <p>I learnt about system chaincode of Hyperledger Fabric and I know there have 5 chaincodes are: LSCC(Lifecycle system chaincode), CSCC(Configuration system chaincode), QSCC(Query system chaincode), ESCC(Endorsement system chaincode) and VSCC(Validation system chaincode). Since I want to modify some conditions in ESCC when I build a network in Hyperledger Composer then I do not know where is ESCC. Anyone please help me, your answer is highly appreciated.</p>
