The Top 10 rejected blockchain business ideas

How hot is blockchain right now? Rumour has it that over 26,000 blockchain-related projects were started up last year on the software collaboration platform GitHub, an impressive number, considering only eight per cent of these are still actively maintained.

That says something about the feverish workings of the coder’s hive brain (although most GitHub projects, up to 90 per cent according to estimates, get dropped anyway), but it also speaks to the hype surrounding blockchain’s distributed ledger idea. Yes, it’s supposed to change the way everything works everywhere, but what can it really do?

“[Blockchain] is a tool, and you have to apply it to the right set of problems,” says Charles Cascarilla, CEO and co-founder of blockchain fintech company Paxos, to Bloomberg News. “What it tends to be very good for is knowing who owns what and when,” says Cascarilla. “It’s not a magic bullet.”

Say it ain’t so! Beyond the Bitcoins and banks out there, blockchain is the very reinvention of the trust paradigm (bluntly, let’s take out the middle man), so surely it’s got an unending supply of potential applications.

Take health care, for instance. Many see the day when instead of your patient records being all over the place and unaccounted for — this jab here, that prescription there — you get a blockchained record, time stamped and verified for every transaction you’ve ever had with a medical professional.

“Now is probably the right time in our history to take a fresh approach to data sharing in health care,” says John Halamka, chief information officer at Boston-based Beth Israel Deaconess Medical Center, to Wired.

That’s more like it! What about retail and agribusiness? You want your tomatoes tracked and verified, from seed to fruit to back of the truck to you? You got it. “There’s a lot of fraud in food origins, especially now that it’s hot,” says Caroline Myran, project manager for, the self-professed “Blockchain of Food” company. “People say ‘this is local,’ or ‘this is organic,’ or ‘this is grown using certain practices.’ With this system, you can prove it.”

Blockchain your weed supply? IBM says we gotta have it, Canada.

Want to blockchain your resume before that next interview? “Career verification” platform APPII is your new best friend.
