PoUC 1.0 — Proof of Useful Contribution I built PoUC (Proof of Useful Contribution), an independent open-source protocol experiment based on the Polkadot SDK and FRAME. The idea is simple: PoUC explores whether useful, verifiable work can become portable on-chain contribution history, credentials, and reputation. Current Status PoUC 1.0 is a runnable Testnet/RC implementation. It is not an official Polkadot project, not a production parachain, and does not claim deployment with Polkadot shared security. What is implemented and tested Contribution records with on-chain duplicate and fingerprint prevention Signed L1/L2/L3 verification Credential lifecycle, revocation, and appeal handling Contribution-derived reputation Bond-free, reputation-qualified Collator eligibility Session-key registration and deterministic active-set selection Non-authoring full-node support without PoUC staking or bond Evaluation DApp AI Safety / Red-Team DApp Portal and typed TypeScript SDK/API clients Off-chain evidence storage using content-addressed commitments and local replicas Native Linux and WSL2 testnet runbooks Tokenless Design PoUC 1.0 deliberately has no PoUC native token, staking, candidacy bond, reward, or monetary-slashing path. Any base transaction-fee plumbing retained from the SDK is infrastructure, not a PoUC contribution economy. In the current runtime design, Collator candidates need: Registered Session Keys Contribution-derived reputation of at least 10 No enabled Verifier or Independent Reviewer role conflict Candidate selection is deterministic and reputation-qualified, with a DevNet Invulnerable fallback and liveness-based removal. Mobile Edge Node The Android client has also been tested on a Pixel 6a as a lightweight Edge Node / observer and relay client. It does not run the Rust chain node and is not a Polkadot Validator or Collator. Why PoUC? AI is creating a large amount of work around: Model evaluation Safety testing Human feedback Data contribution Verification I believe there should eventually be an open layer that can answer: PoUC is my attempt at exploring that layer. Feedback I'm especially interested in feedback from people familiar with: Polkadot SDK Substrate / FRAME Decentralized reputation Identity Network economics This is an early technical experiment. I'm more interested in criticism and implementation feedback than promotion.

Cannot see commission rates of validators any more?

Thu, 10 Sep 2026 03:49:18

Does anyone know why Polkadot https://staking.polkadot.cloud no longer shows commission rates of validators any more? I heard Polkadot has implemented a min 10% commission change, but how to find out if a validator sets the commission rate even higher? submitted by /u/better_place_for_all [link] [comments]
