This is a framework for working with SQL transactions in a distributed network. The framework allows you to compose SQL transactions of multiple queries on different nodes and execute them later.

To ensure the reliability of the transactions a ledger using blockchain is used to keep track on ongoing transactions and ensure queries within the transactions are consistent.
