The Pangram problem
Pangram is one of a growing number of services that promise to spot AI-generated text. But its recent calls have gone wrong, at least according to the writers involved. A novel was pulled from publication after the tool flagged it. A short story that won a Commonwealth Prize also came under fire. In both cases, the writers say the work was human-made. The disputes are unresolved, but they've already had consequences.

The cost of a false positive
For writers, a false accusation isn't just embarrassing. It can sink a book deal, cost an advance, or tarnish a reputation that took years to build. The pulled novel represents real money lost. The prize-winning story carries a stigma that's hard to shake. Detection software offers quick answers, but it's probabilistic, not deterministic. False positive rates are often undisclosed. That means a writer can be accused without any way to prove their innocence.
Why blockchain fits
This is where the crypto angle comes in. Blockchain offers a way to prove authorship that doesn't rely on a central authority. A writer can timestamp a draft, sign it with a private key, and store the hash on a public ledger. That creates an immutable record of when the work was created and by whom. If a detector later flags the text, the writer can point to the on-chain proof. No more he-said-she-said. This is the kind of use case that crypto advocates have been waiting for: a real, painful problem that blockchain can solve. It's not just about protecting individual writers. It's about restoring trust
