Distributed Ledger manages the world state and the transaction log in the blockchain. The world state is defined as the state of all transactions on the Blockchain, where all nodes agree that all blocks on the Blockchain are at the same state. It implements three key attributes. It efficiently calculates the cryptographic hash of the entire dataset of each block. It efficiently transmits a minimal ''delta'' changes to the dataset, when a peer is out of sync and needs to ''catch up''. It minimizes the amount of stored data required for each peer to operate.

The security module works in conjunction with the membership service module to provide access control service to any data recorded and business logic deployed on a chain network.
