NETHERMIND's ECOSYSTEM

A growing community of collaborators

Collaborating to drive Ethereum forward

The Nethermind project was bootstrapped in 2017 and received an Ethereum Foundation grant in 2018 to deliver the full-client implementation. Our unwavering commitment towards strengthening the Ethereum protocol remains strong and we closely align our development and research efforts with its roadmap.

Paprika

A custom database implementation for Ethereum state and storage trees in the Nethermind client. This project aims to set a blueprint for reorganization-aware, checksum-based storage systems.

Libp2p

Libp2p is a modular and future-proof networking stack that addresses P2P protocol limitations. Nethermind is implementing this library in .NET, with the aim of making it available as a public good.

Ethereum Object Format (EOF)

EOF proposes improvements for the Ethereum Virtual Machine (EVM). Nethermind is one of the first clients to implement EOF, which optimizes Ethereum's performance and offers a more developer-friendly environment.

Account Abstraction

Nethermind, with Ethereum Foundation and OpenGSN, collaborated on EIP-4337 for a user-friendly and decentarlized implementation of account abstraction.

EIP-4844 Shard Blob Transactions

Proto-danksharding introduces a transaction format with added data 'blob' space, reducing rollup costs. Nethermind’s implementations of this specification is boosting Ethereum scalability efforts.

Verkle Tree

Our team actively develops and tests the Verkle Tree implementation on Nethermind, collaborating with other Ethereum client teams to ensure a seamless transition from Merkle to Verkle Trees.
