These used to get talked about endlessly. IBM built its entire blockchain business around the idea of logistics and ran expensive TV ads promoting the IBM blockchain for years. The problem is that for all that was promised, in reality what we have are a few very specialized niche uses. The fundamental issue with the blockchain is that the case for a “trustless” database as opposed to outsourcing it to a single trustworthy are very limited. And the cases where the benefits outweigh the significant operational complexities are even more limited. And that’s before you consider that 50%+1 attacks exist. So even the “trustless”ness is vulnerable to attacks.
