Query: Optimizing Validation Phase of Hyperledger Fabric   Blockchain technologies are on the rise, and Hyperledger Fabric is one of the
most popular permissioned blockchain platforms. In this paper, we re-architect
the validation phase of Fabric based on our analysis from fine-grained
breakdown of the validation phase's latency. Our optimized validation phase
uses a chaincode cache during validation of transactions, initiates state
database reads in parallel with validation of transactions, and writes to the
ledger and databases in parallel. Our experiments reveal performance
improvements of 2x for CouchDB and 1.3x for LevelDB. Notably, our optimizations
can be adopted in a future release of Hyperledger Fabric.
