When diving, I often find myself staring blankly at the coral reefs. The hard coral exoskeletons are as solid as rocks, while the algae hidden inside quietly perform photosynthesis, providing energy for the entire ecosystem. Two completely different existences are intertwined, creating the liveliest community in the ocean. This reminds me of what @build_on_bob is doing. Bitcoin is like the coral exoskeleton, firmly rooted with a decade of accumulated security; Ethereum is like those algae, generating countless applications through the vitality of smart contracts. BOB is like twisting these two together, using a hybrid chain architecture to combine Bitcoin's "sturdiness" with Ethereum's "flexibility". Zero-knowledge proofs are like the mucus secreted by coral polyps, tightly wrapping the collaboration on both sides; the Bitcoin staking system is like the way algae take root, firmly grasping the core security foundation. It turns out that good innovation is really like a coral...
