| It's an extremely rare problem for now because it's a new technology that has barely been explored. Like all technologies once it goes more mainstream people come up with new ideas that were never thought of because they weren't possible before. Blockchains solve the problem of needing a shared database among people that don't trust each other. Most of the best use cases are removing middle men. Some examples that are being worked on right now: Trading of any financial asset - why do we need Robinhood / Fidelity etc to trade shares? If shares in companies can be listed on a blockchain then people can trade them anywhere anytime directly with each other even when they don't trust each other. Larger markets for digital goods: Many games have started putting their items on Etherum (or layer 2 solutions) so that players can easily trade them without the developers needing to run their own marketplace. This can then extend to being able to use items across multiple games, or trade items from one game with items from another. Now there's ethereum tokens that allow the original creator to get a cut of all trades of that item. This opens an interesting funding model where a company could create an open source permissionless game where you download the client, connect to the public chain, play and acquire items, trade those items with others, and the game creators gain funds based on a cut of all trade happening around the game which allows them to further development. Then because it's open source people can create forks with their own art styles and mod the game easily and people can participate in the same world with many different clients. There's so many cool things happening in the decentralized finance space and I think we're going to look back on this decade as the decade where software started to eat wall street. Many of these firms are merely middle men facilitating trades amongst untrusted parties, and blockchains can do that so much more efficiently than them. |
