After transaction commit completion notification, validate block hashes the same on peers if desired
Each peer logs its block commit hash every block at INFO level. The block commit hash is a hash over all valid transactions that are written to state database. So you can compare block commit hashes across peers to ensure no fork. Look for a peer INFO message every block containing 'commitHash', e.g.:
commitHash=[0d01cbc2d186675855d5b52f2bda5050ff7238d2527062d0fd5c0a8220d817fa]
Some users do like to validate query results by querying a 2nd peer to ensure they get the same results, that certainly is a valid pattern for critical applications.
Related upcoming work:
https://jira.hyperledger.org/browse/FAB-106 - A 'checkpoint' feature will allow peers to bootstrap a channel from a known good state without having to process all prior blocks since genesis block. The feature can also be used to compare global state across peers.
https://jira.hyperledger.org/browse/FAB-33 - BFT for ordering service to ensure a sufficient number of ordering service nodes sign off on blocks.
We will socialize RFCs for these proposed work items once they become available.
Thanks,
Dave Enyeart

- Open
Use of Open Source promotes innovation and better quality code - Permissioning
A permissioned network promotes trust and confidentiality. Unlike anonymous blockchains like Bitcoin and Ethereum, illegal activity can be controlled. - Governance
Universal and transparent governance ensures that the network is not abused and serves the needs of its users. - Standards
Use of interoperable standards encourage innovation. Today’s blockchain implementations are primarily independent entitites. - Privacy
Blockchain should be able to control who can access data and when. Privacy regulations, like GDPR, also need to be complied with.
