The reason why Ethereum EVM is closed is: EVM is built on top of the Ethereum consensus layer, a closed formal network system that cannot perceive the real world. If the use of Chainlink oracle cannot penetrate the Ethereum consensus layer, it can only become the authoritative center of Chainlink to feed data into the EVM closed system. Through GEB's three-layer model, real-world information can be decentralized and transmitted layer by layer to the EVM system. The first layer of GEB: The BitAgere nonlinear perception system perceives the real information in the real world and transmits it to the WASM layer, which is also built on top of the GEB network consensus, through the GEB consensus currency. WASM is the consensus layer above the perceived world, that is, the second layer. Then, in the WASM layer of the GEB network, the data sensed by the BitAgere layer is passed through the WASM layer to the EVM layer. Since the EVM layer is built on top of the WASM virtual layer, the two share all ledger data and can naturally pass through the BitAgere perception layer to the WASM consensus layer, and then to the EVM execution layer.
