Protocol Engineering & Development

Core blockchain protocol development and engineering services, working together with partners and the global developer community to support the health and growth of Ethereum and Starknet. Nethermind provides essential infrastructure contributions, research-driven protocol improvements, and custom chain development for enterprises and Web3 projects.

Ethereum Core Contributions

Nethermind is a core contributor to Ethereum's development with their execution layer client playing an important role in advancing the network. The company actively collaborates with the broader Ethereum community on critical protocol improvements including Account Abstraction (EIP-4337), EIP-4844 Shard Blob (proto-danksharding), Verkle Tree implementation, Ethereum Object Format (EOF), libp2p implementation in .NET, and the Paprika custom database for Ethereum state storage. All core engineering work is open source, contributing to the public good and enabling the broader blockchain community to benefit from Nethermind's technical innovations.

Starknet Ecosystem Infrastructure

Within the Starknet ecosystem, Nethermind delivers core infrastructure including the Juno client (Starknet node implementation), Voyager block explorer and API platform, and developer tools for Starknet builders. The company is deeply integrated in the Starknet community as a core contributor, providing essential infrastructure that powers the network's growth.

Research and Development Domains

Protocol research and development spans consensus mechanism research and optimization, Layer 2 scaling solutions (optimistic and ZK rollups), state management and storage optimization (Verkle Trees, Paprika database), peer-to-peer networking protocols (libp2p), Ethereum Virtual Machine improvements (EOF), protocol security analysis, custom chain development (Cosmos SDK, Substrate, OP Stack), and cryptographic primitives. This work is conducted in close collaboration with the Ethereum Foundation, other client teams, and the broader research community, ensuring alignment with ecosystem priorities.

Custom Chain Development

For enterprises and projects requiring custom blockchain solutions, Nethermind provides protocol-level engineering for chains built on Cosmos SDK, Substrate, and OP Stack frameworks. This includes architecture design, consensus mechanism customization, economic model design, security hardening, and integration with existing enterprise systems.
