This change-set enforces the field TxID of a proposal/transaction to be computed as the result of an hash function computed on nonce and creator. This is to be able to uniquely identity a proposal/transaction. In addition, the endorsers verify that a TxID is not duplicated by looking up the ledger as done by the committers. Before merging this change-set, the client-sdk needs to be modified to generate the TxID in the new expected way. This change-set comes in the context of https://jira.hyperledger.org/browse/FAB-583 Change-Id: Icc5892976aeec1d4fdca736234355833d04bd4c8 Signed-off-by: Angelo De Caro <adc@zurich.ibm.com>
