pohi-core

Chain-neutral core library for Proof of Human Intent (PoHI).

Installation

npm install pohi-core

Features

• Zero runtime dependencies
• Chain-neutral types and validation
• SHA-256 based attestation hashing
• Full TypeScript support

Usage

import {
  createAttestation,
  computeSignal,
  validateAttestation,
} from 'pohi-core';

// Create an attestation
const attestation = createAttestation(
  {
    repository: 'owner/repo',
    commit_sha: 'abc123...',
    action: 'DEPLOY',
  },
  {
    method: 'world_id',
    verification_level: 'orb',
    nullifier_hash: '0x...',
    signal: computeSignal('owner/repo', 'abc123...'),
  }
);

// Validate
const result = validateAttestation(attestation);
console.log(result.valid); // true

API

Creates a new attestation with computed hash.

validateAttestation(attestation)

Validates attestation structure and hash integrity.

computeSignal(repository, commitSha)
