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.

The process by which a blockchain network agrees on the current state of the ledger. Autheo uses QSDAG for quantum-secure finality.
View definition →Cross-Chain Bridge
A cross-chain bridge is a protocol that enables the transfer of assets, data, or messages between two separate blockchain networks. Bridges allow tokens and information to move across chains that would otherwise be isolated, enabling interoperability in a multi-chain ecosystem.
View definition →Cross-Chain Interoperability
The ability for different blockchains to communicate, share data, and transfer assets without relying on centralized bridges. Layer-0 architectures enable this natively.
View definition →Interoperability
