I've been hearing about these use-cases for blockchain for years now ... and still waiting for actual production use.

I'm also skeptical that a regular server-based approach wouldn't be better to solve those issues. If banks and suppliers can get together and agree to use blockchain to track their transactions, they can get together and set up a centralized server to do the same.

Blockchain is a 'technically interesting' architecture in search of a problem to solve.

Preserving the integrity of log files and other records is a very obvious and huge use case. Enterprise products have been on the market for years and have been put into use by companies like Ericsson and Lockheed Martin.

Did these projects actually go anywhere? Those press releases look very aspirational ... and are already a few years old.
