I value the insight of many that post here, so I would like to ask: isn't there any valuable application for blockchain tech? I realize BTC is imperfect, but blockchain itself is just a technology.

Being pretty young, everyone I know is involved in crypto in one way or another. I'm personally waiting on the sidelines, but there should be some beneficial middle ground between going all-in and completely discarding the tech.

Well, money is the biggest use-case of it all. If you don't care about inflation (solved via decentralization), then there's the use-case of verifyably programmable money (ethereum)

Another one that I find fascinating is immutability, things like https://opentimestamps.org/ (uses bitcoin's blockchain), it allows you to proof that X piece of information existed prior to time Y.

I know of 2 different paths of assumptions you need to verify that proof:

1. Somewhat trusting bitcoin block's timestamps and the immutability that proof of work provides to the chain of blocks

2. Having a higher bound estimate of your attacker's ability to generate proof of work, and then sum all the available proof of work (it is sequentially chained in the blockchain from the block's proof, till the latest block produced), and compute how much time the attacker needed to spend to fake that proof of work, and that's your proof of the minimum time that must have passed since X was conceived

Estonia uses a blockchain to act as an immutable way to store timestamped hashes of government data for security and verification purposes - they started building this a year before the Bitcoin whitepaper was released in fact. That's the only valuable use for blockchains I've seen.
