Cryptographically signed proof of authorship and date. The signature is on the English source, translations are derived and shown for convenience.
Declared signer: 0x7511…023b, on May 7, 2025. Verification checks whether the EIP-712 signature recovers this address.

Verify it yourself
Run this in your terminal, no trust in this site required:
npx @jterrazz/attestation verify https://www.jterrazz.com/articles/15-how-to-actually-use-aiThe CLI fetches the markdown bytes, recomputes the SHA-256 digest, recovers the signer from the EIP-712 signature, and validates the OpenTimestamps proof against Bitcoin.
How it works
Signature. The article's canonicalized bytes are hashed with SHA-256, and the hash is signed by an Ethereum wallet using EIP-712 typed data. The signer's address is recoverable from the signature; tampering with one byte invalidates it.
Timestamp. The same hash is anchored into a Bitcoin block via OpenTimestamps. Once a block is mined, the timestamp becomes part of Bitcoin's consensus history, provably no later than the block's mining time.
Trust-free verification. Anyone can verify both properties independently with the CLI above (or by reading the raw files at /articles/15-how-to-actually-use-ai/proof.json). The proof doesn't depend on this site staying online.
Raw artifacts
Four files at /articles/15-how-to-actually-use-ai/ are the entire proof.
