BOB and Risc Zero have collaborated, Anyway, I can't quite understand it technically, Probably BOB (Build on Bitcoin) officially announced that it will adopt the "ZK Rollup" technology, and now BOB is entering the ZK race. After several players fell in front of the ZK track, I hope BOB can carry the banner of ZK. In BOB's third season event, ranked in the top 500, hoping to have good luck.
