Thus, a problem in search of a solution. Who has asked for that exactly ?`It's been more than a decade and still no one has found an actually useful real-world application for blockchain besides gambling and money laundering.
If Company A and B already trust each other not to put bad data on the chain, then they also trust each other to just send emails back and forth, and you don't need a cryptographically verified blockchain. It secures the least important part of the process.
The only way to standardize ~all companies would be to have them all run the same exact ledger system, and if it was easy enough to make them do that, it would be easy enough to have them standardize a different reporting system for the same purpose.
It sank like Titanic. Nobody was interested in it, turns out that companies are fine with emailing each other Excel sheets.
