Penfield (Tupuy) discusses Tansu, a decentralized platform built on Soroban that brings transparency and community governance to open source projects by storing commit hashes on-chain, enabling DAOs per project, and implementing anonymous voting.
In this Stellar Developer Meeting spotlight, Penfield shares his journey from Python developer at Bitpanda to active Stellar community contributor. He presents Tansu, a Soroban-based platform addressing open source governance challenges. Tansu provides on-chain security verification through commit hash storage, per-project DAOs with transparent voting, and a support tipping system. Built with SDF funding, it features IPFS-stored proposals, XDR-based executable outcomes, and upcoming anonymous voting using zero-knowledge proofs. The platform avoids centralized backends, running entirely client-side or on-chain, and integrates with Soroban Domains and the Trustful project for badge-based voting power.
