Forged identities, real consequences
Doctors, lawyers, judges, engineers — high-trust roles can be impersonated with paper credentials and PDF screenshots. The damage is social, financial, and sometimes irreversible.
Est. 2021 · Building since the dawn of the verifiable web
A decentralized truth engine for the digital economy.
DataLink DAO returns data ownership to people and institutions through verifiable credentials, zero-knowledge proofs, and an on-chain registry anyone can trust.

The problem
The information age needs a decentralized truth engine.
Trust is breaking down across credentials, documents, and identity. The web wasn't built for verifiable truth — and the cost of that is showing.
Your data, their profit
Big platforms harvest the data you create and lock it behind their walls. You bear the privacy risk while they capture the upside — with no incentive to keep it safe.
No universal way to verify truth
Without a shared, trustless registry, every institution rebuilds verification from scratch — slow, expensive, and full of gaps that fraud slips through.
The solution
DataLink is the stamp of truth for the open web.
Imagine a database of files and documents across the internet that you know to be true. Among the sea of fakers and bots, verified data carries a digital seal anyone can check — instantly, anonymously, and without a middleman.
- Tokenized credentials as on-chain NFTs (ERC-721)
- Client-side SHA-256 document hashing
- Zero-knowledge proofs preserve privacy
- DAO governance via ERC-20 votes + timelock
You own your data
Credentials and documents stay yours. Share what you choose, revoke when you need, monetize on your terms.
On-chain truth, off-chain privacy
Documents are hashed locally in the browser. Only the proof lives on-chain. Files never leave your device unless you say so.
Incentives, not exploitation
Publishers, verifiers, and DAO members are rewarded through smart contracts and tokenized governance.
How it works
Three steps. Zero compromise.
From publisher to credential to verification — every step is cryptographic, decentralized, and ownership-preserving.
- 01
Publish
Verified institutions register as Publishers and join the DAO. A Publisher NFT proves their authority to mint credentials on behalf of others.
- 02
Tokenize
A document is hashed locally with SHA-256. The hash, metadata, and recipient wallet are minted as a credential NFT — no file ever uploaded.
- 03
Verify
Anyone can drop the original document into the verifier. We re-hash it client-side and check the proof against the on-chain registry. Instant, trustless, free.
Products
Three products, one verifiable stack.
Each piece works on its own. Together they make data ownership real.
DataLink DAO
The governance + economic layer.
Monetize anonymous data-sharing and govern a tokenization platform for credentials, documents, and high-value data. Powered by ERC-20 votes, a timelock, and an OpenZeppelin Governor.
- DAO membership NFTs
- Token-weighted voting
- Treasury & rewards

Technology
A stack designed for verifiable everything.
Open standards, audited primitives, and the best of Web3 — assembled into a developer experience that just works.
Zero-knowledge verification
Prove a fact without revealing the underlying data. Privacy-preserving by default.
Client-side hashing
Documents are SHA-256 hashed in your browser. Files never touch our servers.
On-chain registry
ERC-721 credentials with immutable proof of issuance, ownership, and verification.
Decentralized storage
Filecoin storage deals for tokenized data — durable, distributed, and censorship-resistant.
On-chain governance
ERC-20 votes, OpenZeppelin Governor, and a timelock. The DAO steers itself.
EVM-native
Deployed across Ethereum, Sepolia, and Filecoin networks. Multi-chain by design.
Join the DAO
Data collected about you should be owned by you.
For the information age to move forward, the world needs a decentralized truth engine. Help us build it — as a Publisher, a DAO Member, or both.
