| Over the last decade I've heard lots about the potential of blockchain technology beyond cryptocurrency. But I've heard a lot less about how much of that supposed potential has actually been realised. Every time I meet someone who has anything to say about anything blockchain-related I ask if they can point to a current, real-world blockchain project that isn't basically a cryptocurrency and has made it past being just a prototype or an idea. Literally nobody I've asked has been able to come up with anything that meets those criteria. Can you? |
Non-financial use cases would rely on a blockchain's tamper-resistance: like timestamp hashes for proof that a video happened at a certain time (only useful if this video is alleged to be faked), or something like NameCoin which was a tamper-resistant DNS prototype. Some people are trying to implement digital identity with blockchains, and others are trying to build a social layer in such a way where you own your 'social/friend network' and can view it with any ux you choose.
I think basically all of the marketing-hucksters have rotated into AI (IBM is running ads for AI, not blockchains), so the hype is muted compared to 2017 or so.
