A consensus mechanism is the process by which a blockchain network agrees on the current state of the ledger. Different blockchains use different consensus approaches: Proof of Work (Bitcoin), Proof of Stake (Ethereum), Proof of Authority (many enterprise chains), and others. Autheo uses QSDAG (Quantum-Secure DAG-based finality) as its consensus mechanism, which provides fast transaction finality while maintaining resistance to quantum computing attacks. The choice of consensus mechanism affects a blockchain throughput, security guarantees, energy consumption, and decentralization tradeoffs.
