  • 9 months embedded in Prosopo’s team, January to September 2022
  • 1 Bushido developer across smart contracts, a Substrate node, frontend and backend

What did Bushido do for Prosopo?

A Bushido developer spent nine months inside Prosopo’s team, January to September 2022, on Rust smart contracts with ink!, a Substrate validator node, and the frontend and backend around them. Prosopo is a low-trust human verification system that lets Polkadot dapps block bots without a centralised third party.

The problem

After winning a Web3 Foundation grant in early 2022, Prosopo needed someone at home in Rust contracts, a Substrate chain and the JavaScript around them.

The solution

  1. Joined the team, not a handover.

    Nine months inside Prosopo’s own process.

  2. Built the core: smart contracts in Rust.

    Written with ink!, the smart contract language for Substrate chains.

  3. Worked on the chain itself.

    A Substrate node that serves as a validator in Prosopo’s own parachain.
