A decentralised notarisation primitive

Prove anything about yourself on-chain. Without revealing who you are.

Notachain lets credentialed legal professionals attest off-chain facts on-chain. Each attestation is a boolean you own, you control, and you earn from every time it's read.

The gap

The problem

There is no standardised way for a person to privately communicate verifiable facts about themselves to the blockchain. Oracles bring market data on-chain. Nothing brings human data on-chain — privately, verifiably, and with real-world accountability.

The solution

A credentialed legal professional verifies a fact about you and signs a boolean attestation on-chain. True or false. They face criminal consequences for lying. You face no identity exposure. The attestation lives forever, and you earn every time someone reads it.


The primitive
Every attestation reduces to a boolean

Not "this person earns $85,000." Just "this person meets the income threshold." True or false. Signed by a credentialed professional. Stored on IPFS. Referenced on-chain. Owned by you.

Some booleans, once true, are true forever. You only prove them once.

True — permanent
"The holder of this wallet is over 18 years of age."
Notarised once. Valid forever. Earns on every read.
True — permanent
"The holder of this wallet holds a university degree."
Notarised once. Valid forever. Earns on every read.
True — temporal
"The holder of this wallet uses air-gapped signing."
Re-attested annually. Earns until expiry.
True — temporal
"The holder of this wallet has no prior insurance claims."
Re-attested annually. Earns until expiry.

Blockchains don't need to be trustless. They need trust to be explicit, accountable, and verifiable.

How it works
Two data types. Three contracts. That's the whole protocol.
01

Legal professionals register on-chain

A solicitor, notary, or barrister generates a keypair and registers on the Notachain registry — linked to their credentials, licensing body, and jurisdiction. They stake $PRZ tokens against their registration. They do this once.

02

You make a declaration

You visit a registered professional — the same way you'd make a statutory declaration today. You declare the facts you need attested. They verify your evidence and witness your declaration.

03

A boolean goes on-chain

The professional signs the attestation with their registered key. The proof document lives on IPFS — self-contained and content-addressed. Only the hash and the signature go on-chain. The boolean is now yours.

04

You earn every time it's read

Any protocol that needs to verify your boolean pays a read fee in $PRZ. The fee splits between you, the attestor, and a protocol burn. Your attestation is no longer a cost — it's a revenue-generating asset.


$PRZ token economics
Everyone earns. The network self-corrects.

The $PRZ token bootstraps the network, penalises fraud instantly, and creates a self-correcting supply mechanism that becomes more deflationary as the network matures.

Wallet holders

Earn from your own data

Every boolean you notarise earns $PRZ when protocols read it. The more useful your attestations, the more you earn.

Attestors

Residual income forever

Legal professionals earn a share of every read fee on every attestation they've ever signed. The incentive to join is economic, not ideological.

The protocol

Self-correcting supply

An inverse sigmoid emission curve drives high rewards during growth, tapering as the network matures. The network becomes deflationary at scale.
