Authcoin: Validation and Authentication in Decentralized Networks

TL;DR

Authcoin introduces a blockchain-based validation and authentication system that enhances security and resilience in decentralized networks, addressing limitations of traditional PKI and trust models.

Contribution

It presents a novel challenge-response validation method integrated with blockchain storage, improving resistance to sybil attacks and decentralization.

Findings

Resilient to sybil attacks

Decentralized validation process

Enhanced security over traditional PKI

Abstract

Authcoin is an alternative approach to the commonly used public key infrastructures such as central authorities and the PGP web of trust. It combines a challenge response-based validation and authentication process for domains, certificates, email accounts and public keys with the advantages of a block chain-based storage system. As a result, Authcoin does not suffer from the downsides of existing solutions and is much more resilient to sybil attacks.
