And there’s a lot of money going around. Cryptocurrencies are wildly volatile, but in June, Golem was worth more than $300 million, according to CryptoBriefing.com. Its network is expected to include video-game developers, graphic designers, and movie producers who seek supercomputing power without supercomputing costs. Gridcoin, a startup built on Boinc, rewards volunteers with coins they can use at online marketplaces like Cointopay, which sells vintage Gucci handbags and Hermès belts. (It also sells less savory items–it is a crypto market, after all.) Golem and Gridcoin represent a new kind of meta-platform, where consumers, businesses, and the platform developer can all benefit.
