On August 30, according to Protos, Lava founder Shehzan said that it is expected that there are about 400 "second-layer" solutions running on the Bitcoin blockchain. Shehzan pointed out in the "Gwart Show" on August 25 that the actual value of these roll-ups and alternative blockchains is questioned. Some people believe that the number of such projects is only 80 to 85, while some estimate that there are more than 1,000. The difference in estimates is so large because anyone can "roll-up" data and broadcast a tiny hash to any miner, which technically creates a "Bitcoin second layer." Many of these second-layer solutions are simple clones of Ethereum roll-ups, mainly processing data on centralized servers outside the Bitcoin network and regularly broadcasting state hashes to Bitcoin blocks.
