Consensus: Proof of Authority

Tetreum adopts Proof of Authority as its consensus model.

In this design, a fixed set of approved validators is responsible for validating transactions and producing blocks. The whitepaper presents this as a way to achieve fast block production, lower energy usage, and predictable operations.

Claimed advantages

• High throughput

• Energy efficiency

• Reduced fork risk

• Accountability in validator operations

The network is described as using the Clique PoA engine, where validators produce blocks in a rotating sequence and each block is signed by an authorized signer.
