How It Works
1
Content Signing
const { publicKey, secretKey } = nacl.sign.keyPair();
const signedHash = signContent(contentHash, secretKey);
2
IPFS Storage
const cid = await ipfs.add(JSON.stringify({
content: articleContent,
signature: signedHash
});
3
On-Chain Registration
await contract.methods.registerPost(
contentHash,
signedHash
).send({from: userAddress});
