I don’t believe it has any current benefit when linked to physical real world actions/items, companies who make broad brush statements like “it can help increase supply chain transparency” really are missing the fact there’s better/easier ways to do that sort of thing. That being said I think it does have good applicability to digital-only activities which require trust, a good example might be Poker, I think generally we believe that a company like Pokerstars are fair and honest so when we jump online to play a game we don’t question it, but there may come time when that’s not the case - where we don’t trust the software created by casinos and bookmakers. So I think generally speaking, right now, gambling is the number 1 use case for Blockchain in my opinion. There’s definitely challenges in this space though, for example building a Poker game on Ethereum would be impossible at the moment, transaction cost for each move would be completely cost prohibitive and there’s still challenges with random number generation, but these problems are solvable. The other thing I think about with blockchain is generally speaking the view is that they should, in theory, outlast tech companies, as the view is that these public ledgers would be maintained collectively by society, it would be nice to be able to keep certain forever record to pass through generations of families to avoid things getting lost in the digital world, but that’s hope, hope that the blockchain you choose is maintained etc, so that’s just as much of risk as now - but it pains me I don’t know much about my great great grandparents, and would hope future generations don’t have that same problem, I wouldn’t want to rely on tech companies to help with that, it would be much nicer to have a record which is decentralized. |
There isn't any method possible where you don't have to rely on a trusted third party - and that's the entire problem blockchain is trying to solve.
The main question in the post should be "what information do i want to know without having to trust anyone, because it's verified by a number of 3rd parties before i view it"
E.g. every single finance/share/security transaction, tracking info of humanitarian aid, government spending, sales direct to an artist (tickets etc)
Before you say "but everyone can see", encryption exists for a reason - https://en.wikipedia.org/wiki/Zero-knowledge_proof
