Ethereum is a better choice because no impact on climate change and it’s more secure. Also smart contracts make it more convenient to store information. You can build a contract that allows anyone to publish a hash in 5 minutes. You could have a map from address to an append only list of hashes. Anyone who calls the publish(bytes32 hash) function just adds to their own list.

Less impact, surely. Not zero impact.
