This piece sheds light on several BTC-related public chain initiatives that have garnered venture capital backing, including BounceBit, Merlin Chain, B² Network, BOB, and Mezo. These ventures seek to broaden Bitcoin's applicability, leveraging its security to forge standalone POS public chains and bolstering their ecosystems with innovations like Restaking and zk-Rollups. Collaborating with giants like Binance, BounceBit, and featuring high Total Value Locked (TVL), Merlin Chain employs a unique hybrid Rollup structure. Meanwhile, B² Network aspires to be at the forefront of Bitcoin's Layer 2 solutions, BOB methodically integrates Bitcoin's security features, and Mezo, crafted by the tBTC team, champions a Proof of HODL consensus model. The narrative underscores the pivotal role of financial backing over technical prowess for these projects. For the average investor, engaging in airdrops and rewards programs emerges as a viable profit-making strategy.
