Proof of Creation — Timestamping a Track on the Blockchain

What blockchain timestamping does

A blockchain timestamping service lets you record:

• A cryptographic hash of your audio file.
• The timestamp at which the hash was submitted.
• Optionally, the metadata (composer, title, etc.).

The blockchain acts as a notary — public, verifiable, and tough to forge. The hash proves the audio file existed at the time of submission (or earlier, if you claim earlier).

How it works

1. Generate a hash. You feed your audio file through a hashing algorithm (SHA-256 is common). The result is a fixed-length string that uniquely identifies the file.
2. Submit to the blockchain. The service submits a transaction with your hash + metadata + timestamp.
3. Receive a record. The service sends you the transaction ID. Anyone can verify on the blockchain that your hash was submitted at your stated timestamp.

The blockchain record proves: at time T, hash H existed. It doesn’t prove you own the audio — just that the audio existed in the form you recorded.

Why composers use it

• Pre-emptive evidence. If a copyright dispute arises later, you can point to the blockchain record as proof of the work’s existence at the time you say.
• Web3 platforms that require it. Some Web3 platforms require a blockchain record before listing a track.
• Peace of mind. The cost is low, the upside is real.

Where it falls short

• Not a substitute for copyright registration. Courts in the US, UK, and EU treat copyright registration as the primary evidence. Blockchain records are supporting evidence.
• The hash doesn’t prove authorship. The hash proves the file existed; only the original creator can claim authorship.
• Custody is still required. The proof only holds if you have the original audio file.

How an indie composer should use it

1. Register the track with your PRO and the MLC. Primary copyright registration.
2. Timestamp on the blockchain. Secondary proof.
3. Maintain the original file. Authorship proof.

The combination is stronger than any single layer.

Where LicenseTrack fits

LicenseTrack is a fingerprint-based monitoring system, not a timestamping service. But it’s a natural complement: the blockchain records prove the work exists; LicenseTrack catches the use of it.
