QSDAG
Quantum-Secure DAG-based finality. The consensus mechanism used by Autheo that provides fast transaction finality with resistance to quantum computing attacks.
QSDAG (Quantum-Secure DAG-based finality) is the consensus mechanism used by the Autheo blockchain. It combines Directed Acyclic Graph (DAG) data structures with post-quantum cryptographic primitives to achieve fast transaction finality while maintaining resistance to quantum computing attacks. DAG-based consensus allows multiple transactions to be processed in parallel rather than sequentially, improving throughput compared to traditional linear blockchain architectures. The quantum-secure element means that the cryptographic signatures and verification processes use algorithms (Kyber, Dilithium, Falcon) that cannot be broken by quantum computers.
