About Status
Status is building the tools and infrastructure for the advancement of a secure, private, and open web3.
With the high level goals of preserving the right to privacy, mitigating the risk of censorship, and promoting economic trade in a transparent, open manner, Status is building a community where anyone is welcome to join and contribute.
As an organization, Status seeks to push the web3 ecosystem forward through research, creation of developer tools, and support of the open source community.
As a product, Status is an open source, Ethereum-based app that gives users the power to chat, transact, and access a revolutionary world of DApps on the decentralized web. But Status is also building foundational infrastructure for the whole Ethereum ecosystem, including the Nimbus ETH 1.0 and 2.0 clients, the Keycard hardware wallet, and the Waku messaging protocol (a continuation of Whisper).
As a team, Status has been completely distributed since inception. Our team is currently 150+ core contributors strong, and welcomes a growing number of community members from all walks of life, scattered all around the globe.
We care deeply about open source, and our organizational structure has minimal hierarchy and no fixed work hours. We believe in working with a high degree of autonomy while supporting the organization’s priorities.
About Waku
We are building Waku as a public good infrastructure. Waku is uncompromising Web3 communication at scale. It is a decentralized, censorship-resistant, privacy-preserving communication network that enables anyone to send and receive messages without worrying about surveillance or deplatforming.
We are enabling Ethereum builders to create new projects with a fully decentralized architecture, think dApp to Wallet notifications, NFT marketplaces, censorship-resistant chat, layer-2 and more.
Waku enables a variety of complex use cases and applications. To facilitate the adoption of Waku, you will design and implement application protocols to provide to dapp developers as off-the-shelf SDKs.

Nimbus is a research team that focuses on developing an Ethereum client and library targeting both Ethereum and the upcoming, proof-of-stake-based ETH2. We believe that the largest deployment of Ethereum will potentially be on embedded systems, Nimbus will be designed to perform well on embedded, mobile, and generally resource-restricted devices. The extensible, configurable, and modular design of Nimbus will make it production ready for Web 3.0 and will ensure that it can be supported and maintained across all goals of Ethereum 2.0.
Building the stack from the ground up, we’re translating the latest Ethereum 2.0 research into practical, performant and reusable libraries to provide fertile exploration ground for further R&D. Check our latest update!
