A practical use for blockchain: disarming censors

An interesting news story out of China:

The predictable, sad but not really noteworthy bit: a vaccine manufacturer saved money by making bogus vaccines and its executives were hauled away by police.

The predictable government response: delay publication of the news, as it implies a corrupt regulator and suppress subsequent social media posts on the subject.

The interesting and innovative bit: repost the story as metadata in an Ethereum transaction, such that it gets replicated across all participants in that blockchain and becomes impossible to tamper with or delete.

This is fascinating! An interesting way to totally defeat, once and for all, state authorities bent on censorship. Just encode public messages in blockchain transaction metadata. Brilliant, though dangerous (what if the state figures out who issued/signed the transaction? jail time at a minimum).

Most of the interest in blockchain is conjecture about hypothetical use cases, but this use case is legitimate and practical – a rare thing.
