Improve the JS library. The JS library gives “undefined” as output. It would be better for us to do the testcases if it outputs tx status and tx hash. (Right now, I used iroha-helper-ts, but it could be further optimized)
Iroha docker container
Upgrade Iroha version. Currently, using Iroha v1.2.0, should be upgraded to improve Iroha’s performance
The Postgres database docker instance could be replaced by RocksDB ( needs just one folder - it should be docker volume - to keep data between different runs of image.)
