The idea is to replace social proof (that the timestamps are correct wherever it is published) with cryptographic proof, but I commented below on some of the pitfalls of doing so.

I provided a cryptographic proof that does not require blockchain.

No, yours relies on social proof (the post being public somewhere) as the timestamp. Nothing about what you described is different from just posting a hash of the prediction beforehand.
