Blockchain requires a tremendous amount of electricity, contributed by all those participating in the cryptographic portion of the network. If you're not using blockchain to create a tamper-proof log, you shouldn't be wasting the planet's resources on a blockchain project.

Even if you can roll back the requirement to "tamper-resistant" you can get away from the necessity of blockchain: use a hash chain instead.

Since you don't care about tampering, I request that you avoid blockchain.
