Since the last research update, IC3 researchers explored order-fairness for consensus, cryptocurrency wallet design, validating bridges, and more! Registration is open for the Science of Blockchain Conference (SBC '22).
The Science of Blockchain Conference 2022 (SBC'22, formerly called the Stanford Blockchain Conference) will be held jointly by the Stanford Center for Blockchain Research and IC3 and co-chaired by Dan Boneh (Stanford) and Ari Juels (Cornell Tech, IC3)! See more and register on the CBR Website.
The talk submission deadline is November 23, 2021, 11:59pm PST.
The author introduces transaction-order-fairness, a new kind of consensus property that enforces strong guarantees on the final execution ordering of transactions. Order-fair consensus protocols are designed to make systems fairer for ordinary users by removing problematic forms of MEV.
The author took steps to answer the questions: how many cryptographic signing keys should one use, what type, and how does one design her wallet to secure digital assets like cryptocurrencies and NFTs?

The authors present a Systematization of Knowledge of off-chain systems which rely on a validating bridge smart contract to self-enforce the safety of user funds and liveness of transaction execution.

Themis is designed for partially synchronous networks, enforces the strongest notion of fair ordering proposed to date, and achieves the same asymptotic complexity and comparable performance to state-of-the-art consensus protocols without any ordering guarantees.

The authors design and evaluate a mempool protocol, Narwhal, specializing in high-throughput reliable dissemination and storage of causal histories of transactions. Narwhal tolerates an asynchronous network and maintains high performance despite failures. They propose separating the task of reliable transaction dissemination from transaction ordering, to enable high-performance Byzantine fault-tolerant quorum-based consensus.
