Best uses of blockchain technology?
Blockchain and Smart Contracts are the future of Supply chain and Decentralization. Many Entrepreneurs are searching for exceptional ideas for a successful crowdfunding.
I don't think there is a single answer to the best use. The thing is that the blockchain can be used to solve all sort of problems that require trust, and you could essentially remove the element of trust from any transaction. The biggest causes would be things that requires middle-men these days, that could instead be solved by a smart-contract.
Blockchain technology always boils down to one thing, and that's DECENTRALIZATION. Any product that exists today can be decentralized if they act as a middle man between a consumer and a product.
For example, Quora technically is a middle man between content writers and their earnings. A site like Musing is able to ensure that we can all make money fairly..
blockchain provides smart contract, cloud storage so that you can store the data of millions of yeas and financial services , and also you get digital identity with which you never need to worry about security.
