Summary

MiD (My decentralized face identity) is a privacy-first face authenticator designed to simplify and secure the way users interact with Polkadot wallets and dApps.

Instead of relying on seed phrases or passwords, MiD locally stores an encrypted facial template on the user’s browser. This enables frictionless, secure sign-ins and the ability to approve on-chain actions like votes, token transfers, and content publishing — using only your face.

Problem

⦁ Too many users lose access to wallets due to poor seed phrase management.

⦁ UX remains a major blocker to mass Web3 adoption.

⦁ We need a human-first solution that ensures:

⦁ Proof of personhood without revealing identity

⦁ Easy login and usage across dApps

⦁ Sybil resistance for content platforms, DAOs, and governance

Solution: MiD (My Decentralized Face Identity)

MiD provides:

⦁ Local, encrypted facial authentication

⦁ Sign with Face for and authorize wallet signature for sensitive on-chain actions (optional)

⦁ Sybil-resistance & real-user verification

⦁ Plug-and-play UX layer for dApps, wallets, and JAM services

⦁ No biometrics ever stored on-chain or in the cloud

Why MiD Matters to the Polkadot Ecosystem

In his recent remarks at the Web3 Summit, Dr. Gavin Wood highlighted the future importance of:

“Validators and services requiring not just stake — but proof of personhood, trust, and sybil resistance mechanisms.”

MiD is a step toward that future

By offering Proof of Personhood through face uniqueness, MiD supports:

⦁ Polkadot Identity Pallets

⦁ KILT Protocol (future integration)

⦁ JAM protocol (future microservice-friendly identity)

⦁ Wallet UX — faster, human-first flows

⦁ Growing the real user base of Polkadot

“We will need to combine stake + PoP + anti-sybil if we want to make identity work.”

How It Works

⦁ After face registration, MiD cryptographically connects your face to Polkadot wallet and saves a faceprint (not the face) locally in the browser — fully encrypted.

⦁ When a user visits a MiD supported Polkadot wallet or dApp, they can authenticate using their face, without entering a seed phrase.

⦁ MiD allows users enable wallet signature (optional) before signing sensitive on-chain actions, like:

i. Treasury proposals

ii. Signing contracts

iii. Token transfers

iv. DAO voting

v. NFT minting

Your face becomes your signature.

Example Of Use Cases

Subsocial (Decentralized Social Media)

⦁ Prevent bot spam and fake accounts using MiD’s face uniqueness

⦁ Offer verified creator profiles without needing KYC

DAOs & Governance

⦁ Face-gated voting to ensure each participant is a real, unique person

⦁ Helps mitigate sybil attacks and ballot stuffing

JAM Services (Coming to Polkadot)

⦁ Allow services to request human access without third-party identity providers

⦁ Use MiD as a modular identity layer .

MiD Future Compatibility

MiD is built with modularity and interoperability in mind:

⦁ Ready for integration with decentralized social (Subsocial) and identity networks (KILT)

⦁ Serve as a frontend user layer for on-chain access control, DAO participation, and even decentralized passports

⦁ Compatible with JAM’s service-oriented architecture

Who This Benefits:

⦁ Users: Face-authenticated access to their wallets and identity — no seed phrases

⦁ Builders: Simple SDK to add human authentication to any dApp

⦁ Governance: More sybil-resistant voter bases using real-human gating

⦁ Polkadot’s Growth: Friendlier onboarding for non-technical users = more adoption

Milestones (Simplified)

1. Phase 1: MVP Browser SDK + face capture (local only)

2. Phase 2: Polkadot wallet integrations (e.g., Talisman, Polkadot JS)

3. Phase 3: JAM module and dApp service compatibility

4. Phase 4: Identity attestation integration

Why Now?

MiD aligns with:

⦁ Polkadot’s vision for modular, interoperable identity

⦁ JAM’s need for real human service access

⦁ The ecosystem’s shift toward trust, safety, and usability

⦁ JAM is coming, JAM’s need for real human service access — and identity is key.

⦁ Onboarding new users requires familiar, safe UX.

Team

I'm not a developer. I’m a user who lost access to multiple wallets due to bad UX and seed phrase issues — and that experience inspired MiD.

I'm leading this as a founder, teaming up with technical contributors to deliver a secure, useful identity experience for the ecosystem.

Call for Support

We believe MiD could be a foundational identity layer for Polkadot's future — including JAM, wallets, content platforms, and more.

We welcome:

⦁ Feedback

⦁ Collaborators (devs, reviewers, Subsocial/JAM teams)

⦁ Treasury support from the community

Let’s add a layer of humanhood to Web3.
