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.
I'm just a newb passing, but a self sustained decentralized 24/7 logic+network layer could be nice for stupid computational tasks like tracking physical items or updating multi-source (different services, different companies) data easily, which are often done at the human level today (even if 99% of the time it's not necessary and very wasteful). Again i'm not knowledgeable but when thinking of blockchains, I always have this in mind.
It can't track physical items, because you can always just lie about the data. Company A says "I put the jewels in box 1352", and Company B opens the box to receive a bunch of dish towels. Just because it's cryptographically verified, doesn't mean it has any semantic value.
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.
No, they don't do any of that. There are 100 different blockchain implementations at least, and none of them are standardized across any of those metrics. Everything from the consensus mechanism to the packet format to the bytecode is different. The standard way to interop between the Tezos blockchain and the Polygon blockchain is to create a token on both sides and attach a tag saying "don't touch me I'm actually somewhere else".
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.
Yeah I think i remember stories about that, that said, a failed attempt doesn't mean future will not be different (nobody seeing programming languages evolution as comparison point). Neither will it means that a decentralized event chain store is the solution.. just saying it kinda felt like an interesting "small logic global network application layer" .. which felt way more efficient than the litany of different b2b apps.
