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.
