Sui Network Achieves 297k TPS

Sui uses a delegated proof of stake (PoS) mechanism to secure the network from sybil attacks, where validators and delegators take on acts similarly to other dPoS mechanisms.

The unique element of Sui’s network level architecture is the protocols leading to consensus. Narwhal is the protocol developed to create and efficiently manage a mempool for a directed acyclic graph (DAG), which Sui uses. Bullshark, the consensus protocol, then pulls transactions from the Narwhal mempool to validate and finalize transactions. As mentioned above, certain transactions can actually by-pass the consensus mechanism and follow the Byzentine Consistent Broadcast mechanism to achieve finality in less than half a second with true settlement guarantees.

This network design has shown to reach transaction speeds of over 297,000 transactions per second in a testing environment.
