Odaily Planet Daily News Lava founder Shehzan said that it is estimated 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 believe that the number of such projects is only 80 to 85, while some estimate more than 1,000. The estimates vary so much because anyone can "rollup" data and broadcast a tiny hash to any miner, which technically creates a "Bitcoin second layer." In fact, many are simple clones of Ethereum rollups, handling almost all activities on centralized servers outside the Bitcoin network and broadcasting regular hashes of that state into Bitcoin blocks.
