Core protocol engineering company behind Polkadot and parallel decentralized infrastructure
Parity Technologies is a core blockchain engineering firm founded in 2015 that develops foundational decentralized infrastructure. Working alongside the Web3 Foundation, the firm led protocol development for the rollout of Polkadot in 2020 and is the primary technical contributor to the Polkadot ecosystem, including its Join-Accumulate Machine (JAM) upgrade.
The company was founded as EthCore in 2015 by Ethereum co-founder Dr. Gavin Wood alongside Aeron Buchanan, TJ Saw, Ken Kappler, and Jutta Steiner. Björn Wagner joined as a co-founder in 2016 and established the ecosystem development unit. In October 2022, Wood stepped down as chief executive officer to serve as chief architect, with Wagner taking over as CEO. Headquartered in London, United Kingdom, Parity operates as a remote-first organization with around 200 employees and four European hubs.
Parity develops protocol infrastructure and developer tooling. Its engineering team maintains Polkadot's core infrastructure. With the development of the Join-Accumulate Machine (JAM), Parity is building an architecture designed to split work across 341 parallel cores into a unified state space. Beyond consensus protocols, Parity creates developer deployment tools for launching testnets with single-click configurations, alongside experimental decentralized storage and frontend hosting tools like Levity.
The technical stack supports the Polkadot and Kusama networks. Parity has explored on-chain frontend resolution via .dot domain names and decentralized storage with renewable retention.
Parity's tooling is focused on the Polkadot and Kusama ecosystems.
Parity Technologies provides foundational, open-source protocol infrastructure and developer tooling for Polkadot and Kusama.
Founded in 2015 as EthCore, Parity Technologies is the primary core engineering entity behind the Polkadot network. Led by Chief Executive Officer Björn Wagner and co-founder Dr. Gavin Wood, the London-headquartered firm developed the foundational protocol architecture launched in 2020 in collaboration with the Web3 Foundation. With a remote-first team of around 200 people across Europe and worldwide, the organization directs its engineering toward core protocol maintenance, parallel computing architecture, and ecosystem developer tooling.
Parity develops core client infrastructure alongside the Join-Accumulate Machine (JAM), an upcoming parallel computing design aimed at splitting protocol computation across hundreds of rented, verifiable cores. Parity also maintains open-source developer tooling. Teams can deploy testnets with single-click actions.
Parity suits teams deploying within the Polkadot ecosystem.

Parity Technologies focuses its infrastructure and engineering development on Polkadot and Kusama. Its tooling supports Polkadot and Kusama infrastructure and includes JAM development.
JAM, or the Join-Accumulate Machine, is a parallel computing protocol architecture developed for Polkadot. It is designed to run smart contracts and multi-agent software across rented, verifiable computational cores that merge into a single shared state.
Parity Technologies releases its core protocol clients and developer tooling as open-source software for teams building on Polkadot.
