Embedding a Deterministic BFT Protocol in a Block DAG
Maria A Schett, George Danezis
This work formalizes the structure and protocols underlying recent distributed systems leveraging block DAGs, which are essentially encoding Lamport's happened-before relations bet…
FastPay: High-Performance Byzantine Fault Tolerant Settlement
Mathieu Baudet, George Danezis, Alberto Sonnino
FastPay allows a set of distributed authorities, some of which are Byzantine, to maintain a high-integrity and availability settlement system for pre-funded payments. It can be use…
SybilQuorum: Open Distributed Ledgers Through Trust Networks
Alberto Sonnino, George Danezis
The Sybil attack plagues all peer-to-peer systems, and modern open distributed ledgers employ a number of tactics to prevent it from proof of work, or other resources such as space…
Replay Attacks and Defenses Against Cross-shard Consensus in Sharded Distributed Ledgers
Alberto Sonnino, Shehar Bano, Mustafa Al-Bassam +1
We present a family of replay attacks against sharded distributed ledgers, that target cross-shard consensus protocols, such as the recently proposed Chainspace and Omniledger. The…
Blockmania: from Block DAGs to Consensus
George Danezis, David Hrycyszyn
Blockmania is a byzantine consensus protocol. Nodes emit blocks forming a directed acyclic graph (block DAG) that is subsequently interpreted by each node separately to ensure cons…
TARANET: Traffic-Analysis Resistant Anonymity at the NETwork layer
Chen Chen, Daniele E. Asoni, Adrian Perrig +3
Modern low-latency anonymity systems, no matter whether constructed as an overlay or implemented at the network layer, offer limited security guarantees against traffic analysis. O…
