[News] Zeke, a researcher at YBB Capital, recently wrote that providing security services through the integrated data availability (DA) layer is no longer a new concept in the era of modular blockchains. The concept of shared security introduced by staking provides a new dimension to the modular field, leveraging the potential of "digital gold and silver" to provide security across Bitcoin or Ethereum and numerous blockchain protocols and public chains. This narrative is quite grand because it not only unlocks the liquidity of trillions of dollars worth of assets, but is also a key factor in future scaling solutions. However, these developments have also raised major concerns. If modularity is the ultimate scaling solution and these protocols are a key component of that solution, they could lock up a large amount of BTC and ETH. This makes the security of the protocol itself the focus of attention. Will the complex layering consisting of numerous LSD (liquidity staking derivatives) and LRT (L2 rollup token) protocols become the biggest black swan in the future of blockchain? Is their business logic reasonable? These questions deserve our in-depth exploration.
