The research arm of Nethermind

In this work, we establish new results on the relationship between various notions of soundness for IOPs.

We establish new results on the Fiat-Shamir (FS) security of several protocols that are widely used in practice, and we provide general tools for establishing similar results for others.

In this post, we research the problem of amortizing costs when one must produce many proofs simultaneously. The method, which we call “packing,” applies to FRI-based SNARKs (e.g., ethSTARK, Plonky2, RISC0, Boojum, etc.).

This paper introduces a novel DEX design, termed COMMON, that addresses these two predominant challenges. COMMON operates as an order book, natively integrated with a shielded token pool, thus providing anonymity to its users.

In the Nethermind Cryptography Research team, we have recently delved into analyzing the security of some SNARKs that are built on top of the FRI protocol. This emerging trend has seen numerous prominent projects utilizing some variation of the ethSTARK protocol or of Plonk compiled with FRI.

his document outlines a protocol which allows for based preconfirmations, while ensuring the based rollup captures much of the value generated from block building.

This article introduces Alternate PBS, a new PBS proposal for based rollups 17. Alternate PBS allows MEV income generated on the based rollup to be captured by the rollup itself, as opposed to being captured through priority payments to the proposer of the sequencing chain.

In this blog post, we will discuss what we consider “incentives’’ in (blockchain) protocols and more.

In this systematization of knowledge, we examine the current innovations and approaches to the field of decentralized identity (also self-sovereign identity), as well as its relevant foundations.

This post reviews two popular digital signature schemes, along with their Threshold Signature Scheme (TSS) versions.

Although staking is used in multiple proof-of-stake networks, this article focuses solely on Ethereum. We will briefly discuss other types of staking, but our main area of interest is the various flavors of liquid staking.

In this post, we discuss the notion of Byzantine Fault Tolerant (BFT) consensus protocols.

This article introduces Distributed Key Generation (DKG) protocols and one of its fundamental building blocks: Verifiable Secret Sharing (VSS) schemes.

In this blogpost, I will explain how to use Shamir's secret sharing to securely share mnemonic keys which are often used to secure cryptocurrency wallets.
