Create a decentralized database with ExAbci and Tendermint
summary
Shows how to assemble ExAbci with Tendermint and a Merkle Patricia tree to make a decentralized, publicly verifiable key/value DB that can survive failures of 1/3 nodes. Implements protobuf transactions signed by clients, stores history in LevelDB/RocksDB, and exposes a GraphQL explorer. Demonstrates a ticket resale app (paisa) that updates ownership and balances correctly. Core framework and explorer are functional but undergoing security, perf and stress tests before open source release.
