FAWAC: An Attack-Resistant, Multi-Enclave Distributed Ledger Architecture

Abstract

We present FAWAC, a distributed ledger architecture and consensus strategy that is decentralized, attack-resistant and provides real-world impact through completion of useful work. A multi-enclave architecture separates fast transaction consensus from computational hard tasks used for validator selection. FAWAC uses an Inter-Planetary File System (IPFS) back-end to provide seamless connection between the enclaves and a modified Byzantine Agreement consensus, which actively checks for faulty behavior, to secure the network. This work provides an architectural level overview of the proposed system design.
