We often say that blockchain is a trust machine, but in my view, current smart contracts are more like amnesiac geniuses. They can execute complex logic instantly, but they can't remember what happened yesterday, let alone make smarter decisions based on past experience. This directly leads to two real dilemmas: 1. Idle Data Goldmine: Massive amounts of user behavior data are stored on the blockchain, but DeFi protocols can't offer better interest rates based on your transaction history, and games can't provide personalized content based on your achievements. It's like owning a gold mine but having no tools to mine it. 2. High Cost of Innovation: Any innovation involving historical data or complex calculations faces exorbitant gas fees, effectively shackled developers' imaginations and keeping blockchain applications at the level of basic financial tools for a long time. The root of the problem is that blockchain sacrifices memory and computing power for security and decentralization, which is a reasonable trade-off. However, if we want to move towards true data-driven and intelligent systems, we must help this amnesiac genius recover. Brevis @brevis_zk The solution presented me with a remarkably ingenious approach to breaking the deadlock. Instead of attempting to fundamentally alter the blockchain's underlying structure, it chose to act as an external brain. My understanding is that Brevis (@brevis_zk), through zero-knowledge proofs, cleverly separates computation from verification. The heavy workload of data querying and computation is moved off-chain, while the on-chain focuses on its core competency: verifying lightweight ZK proofs. This not only solves the gas fee problem but, more importantly, opens the door to the past and the world of complex computations for smart contracts in a trust-minimized manner. This is not merely a technological upgrade but a liberation of imagination. We can expect DeFi that truly understands you, automatically adjusting lending amounts and interest rates based on your credit history. We can also expect self-verifiable on-chain games that implement more complex logic and fairly distribute rewards. Finally, we can anticipate transparent on-chain reputation systems that accumulate and verify your contributions and reputation across protocols. The emergence of coprocessors like Brevis may mark a new stage in blockchain's evolution, moving from a trust machine to an intelligent data machine. Its significance lies in the fact that we are no longer limited by the chain's computational power but can infinitely extend the boundaries of blockchain's perception and thinking.
