Omri Weinstein, the theoretical computer scientist behind Pearl Research Labs, has been trying to solve one of crypto's oldest credibility problems: how to make proof of work useful. A June 3 preprint now argues Pearl has built the hard part of that system a live GPU secured blockchain without proving the work is useful AI computation. Tom's Hardware reported Sunday on a preprint by Abhinaba Basu that estimates Pearl's network is running at roughly 24 EH/s, equal to about 320,000 RTX 3090 cla...
