ChainCatcher news, according to Protos, Lava founder Shehzan stated that there are approximately 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 in question. Some believe the number of such projects is only between 80 and 85, while others estimate it to be over 1,000. The discrepancy in estimates is so large because anyone can "roll-up" data and broadcast a tiny hash to any miner, technically creating a "Bitcoin second layer."Among these second layer solutions, many are simply clones of Ethereum roll-ups, primarily processing data on centralized servers outside the Bitcoin network and periodically broadcasting state hashes into the Bitcoin block.

ChainCatcher news, according to a report by Decrypt, a new report from the EU indicates that Bitcoin's Lightning Network and other L2 solutions are "data obfuscation" technologies that could be "misused by criminals."The report states that the Lightning Network's "peer-to-peer multi-signature payment channels do not broadcast all transactions to the blockchain, but only broadcast the opening and closing of the channels," adding that it and other L2 solutions may pose "challenges for law enforcement investigations."

ChainCatcher news, the decentralized autonomous organization BitDAO community members have approved a governance proposal named BIP-21, which proposes to rebrand BitDAO's governance token from BIT to a new identity, Mantle. BitDAO will merge into Mantle Network.It is reported that through this integration, Mantle Network developers will inherit nearly $300 million in stablecoins and over 270,000 ETH (approximately $485 million) in reserves from BitDAO, which will play a key role in funding the expansion and broader adoption of Mantle Network.In addition, Mantle Network will enter the second phase of its testnet in May, codenamed "Ringwood."

链捕手消息，以太坊二层解决方案 Optimism 宣布将启用多客户端架构。Optimism 表示，L2 中维护升级密钥可能会导致安全问题，而升级密钥的存在的原因是代码编写复杂，很难实现无错误的代码。以太坊通过可互操作性的多客户端生态系统实现高安全性和可用性，Optimism 也将使用多客户端路径去中心化，将目标锁定在把标准以太坊客户端转变为 Optimism 客户端所需不到 1000 行代码上。Optimism 将与外部团队合作并激励他们创建其他客户端，形成 Optimists 联盟并发布 Bedrock 之后，启用多客户端架构。（来源链接）
