Lachesis: Scalable Asynchronous BFT on DAG Streams
Quan Nguyen, Andre Cronje, Michael Kong +2
This paper consolidates the core technologies and key concepts of our novel Lachesis consensus protocol and Fantom Opera platform, which is permissionless, leaderless and EVM compa…
OV: Validity-based Optimistic Smart Contracts
Quan Nguyen, Andre Cronje, Michael Kong
Smart contract (SC) platforms form blocks of transactions into a chain and execute them via user-defined smart contracts. In conventional platforms like Bitcoin and Ethereum, the t…
On Probabilistic Byzantine Fault Tolerance
Quan Nguyen, Andre Cronje
Byzantine fault tolerance (BFT) has been extensively studied in distributed trustless systems to guarantee system's functioning when up to 1/3 Byzantine processes exist. Despite a…
Fast Stochastic Peer Selection in Proof-of-Stake Protocols
Quan Nguyen, Andre Cronje, Michael Kong
The problem of peer selection, which randomly selects a peer from a set, is commonplace in Proof-of-Stake (PoS) protocols. In PoS, peers are chosen randomly with probability propor…
StakeDag: Stake-based Consensus For Scalable Trustless Systems
Quan Nguyen, Andre Cronje, Michael Kong +2
Trustless systems, such as those blockchain enpowered, provide trust in the system regardless of the trust of its participants, who may be honest or malicious. Proof-of-stake (PoS)…
ONLAY: Online Layering for scalable asynchronous BFT system
Quan Nguyen, Andre Cronje
This paper presents a new framework, namely \emph{\onlay}, for scalable asynchronous distributed systems. In this framework, we propose a consensus protocol , which is based o…
Fantom: A scalable framework for asynchronous distributed systems
Sang-Min Choi, Jiho Park, Quan Nguyen +1
We describe \emph{Fantom}, a framework for asynchronous distributed systems. \emph{Fantom} is based on the Lachesis Protocol~\cite{lachesis01}, which uses asynchronous event transm…
OPERA: Reasoning about continuous common knowledge in asynchronous distributed systems
Sang-Min Choi, Jiho Park, Quan Nguyen +5
This paper introduces a new family of consensus protocols, namely \emph{Lachesis-class} denoted by , for distributed networks with guaranteed Byzantine fault tolerance…
