Nimbus was created to promote client diversity and network decentralisation on Ethereum, with the belief that blockchain technology's full transformative potential can only be realised if running Ethereum infrastructure is widely accessible.
Alongside its work building Ethereum clients, Nimbus lends its expertise in decentralised systems to the Logos Collective—a network of aligned projects and contributors building trust-minimised, corruption-resistant governing services and social institutions for its citizens. Nimbus is one of the Logos Collective's foundational projects.
Motivation
Ethereum's security—its resistance to external threats and censorship—comes from its decentralisation. We believe that lowering the barrier to network participation will result in greater decentralisation, and consequently, a more resilient network. As such, we are building each of the three Nimbus clients to be as lightweight, secure, and easy to use as possible.
The Nimbus consensus client, along with the still-in-development execution and light clients, are designed to perform on a range of systems including Raspberry Pis and mobile devices, lowering the barrier to entry to run Ethereum's infrastructure. Meanwhile, our resource-conserving optimizations benefit those operating more powerful systems by freeing resources for other tasks, without compromising on reward performance.
Client projects that were earlier to market than Nimbus have typically developed for higher specification hardware, as one would expect from the first client implementations to serve a new, cutting-edge system like post-merge Ethereum. While their implementations make for a more diverse client ecosystem and their R&D efforts have pushed the space forward tremendously, there remains a gap for an Ethereum client tailored to lower specification devices that encourages increased network decentralisation. Nimbus fills that gap.
In addition to striving for maximum accessibility via lighter client implementations, Nimbus' design goals are to provide an architecture that makes it simple to embed Nimbus into other software. The Nimbus Light Web Proxy, for example, enables decentralised applications to verify data received from external RPC endpoints. Consequently, Nimbus reduces reliance on third-party software and service providers that introduce potential vulnerabilities through single points of failure.
Nimbus history
Status, the creator of the Ethereum-based decentralised messaging application, first announced Nimbus in August 2018 as a client implementation research project focused on sharding, light clients, and next-generation Ethereum technologies, with a goal of addressing scalability and accessibility concerns. It was inspired by a vision of the future in which Ethereum "lives" on millions of embedded systems around the world rather than a few thousand powerful computers.
At its creation, Nimbus' goal was to research and build a client light enough to run on such resource-restricted devices, and modular enough to allow for rapid iteration and implementation of research. Initially the team planned to develop an energy and compute efficient, mobile-first client for the full web3 tech stack, with decentralised logic, decentralised storage, and decentralised messaging.
However, as research into the latter two branches slowed, Nimbus narrowed its focus to crafting high-quality, lightweight Ethereum implementations to promote decentralisation and strengthen the network against single-client failures.
Nimbus was announced as a core Logos project in June 2023.
