Just because some opportunists did a few ICOs does not mean all crypto is bad. Without crypto there would be no online banking, or any form of digital security, secure logins, etc. Crypto is a useful tool. Blockchains are a tool. And so are digital signatures. If you combine those tools, you can do some useful things like creating tamper proof audit logs documenting where information came from all the way from the sensor to your eyeballs. It's just a chain of digital signatures. I tried hard to avoid using the word block chain in the original comment to avoid exactly this kind of knee jerk response. But yes, kind of an obvious tool to use to record chains of evidence in a tamper proof way. Glad you jumped to that conclusion as well. Contrary to the popular belief, not every block chain based thing has to be an investment scam. I don't think we need a separate coin for this; just a shared repository of truth and fact with full auditing. Blockchains are kind of designed to be that. If you know a better way, please provide it. And just to pre-empt it, obviously my preferred flavor of block chain for this would be miner free proof of stake rather than proof of work.

You jest, but distributed publicly verifiable proof that a certain piece of information existed, and was cryptographically signed at a certain date and time, and has not since been modified, is basically the only thing blockchains are actually useful for. And that sounds much like what we need here.

  Even then it's not required, because it's overly distributed. You only need one copy of the Merkle tree (+ backups as necessary); to verify it hasn't been changed you don't need everyone else to copy the whole thing, just random samples of it to verify it hasn't been rewritten recently.
