Aston is a decentralized document distribution network that enables users to better control their personal documents and professional certifications. It records, authenticates, and distributes identifying documents and information, and integrates biometric identification to ensure security.
Aston's platform is based on X-Chain architecture, which has a hybrid consensus mechanism. It combines a Proof of Forkability (PoF) mechanism with a Distributed Proof-of-Stake (dPoS) consensus protocol that stores and distributes data in 3rd dimension sub-chains.
The network is powered by the ATX coin.
