Decentralized genomics audit logging via permissioned blockchain ledgering

We presented creative and efficient techniques for storing and querying log file data in MultiChain
1.0.4 and 2.0 beta. We demonstrated that it is feasible to use a permissioned blockchain ledger for genomic query log
data when data volume is on the order of hundreds of megabytes and query times of dozens of minutes is
acceptable. We demonstrated that evolution in the ledger platform (MultiChain 1 to 2) yielded a 30%-40% increase in
insertion efficiency.
