A strange phenomenon is: According to @ LineaBuild, it has been a week since they claimed to be the world's first zk Rollup to achieve 100% Proven, but it has not caused any backlash from the industry in the segmented track, which is very abnormal in this circle. It is a common phenomenon for Crypto peers to engage in mutual trading and traffic diversion. In my impression, there are @ 0xPolygon accusing @ zksync, @ Aptos accusing @ monad_xyz, Monad accusing @ SonicLabs, @ solayer_1abs accusing @ Eclipse FND, etc. Every time there is mutual trading among peers, it can cause heated discussions in small circles. But this time it did not happen to Linea. From a non academic perspective, I subjectively believe that Linea is indeed the first L2 chain in the zk Rollup subdivision track to achieve 100% Proven. How to understand 100% Proven? In plain language, @ LineaBuild's zkEVM verifies all EVM operations, and the zero knowledge proof system covers every detail of EVM operation code, state transition, gas calculation, and smart contract execution, even including complex logic such as recursive calls and precompiled contracts. 100% Proven brings stronger security while theoretically significantly increasing the time and cost of proof generation. Linea takes a dual approach: putting effort into optimizing the prover and compressing data. The former reduces infrastructure costs to increase efficiency, while the latter reduces data availability costs by 7.5%. Based on a more rigorous principle, I compared @ LineaBuild and other mainstream zk Rollup verification methods and their advantages and disadvantages using Grok. The results are shown in the following figure: Other mainstream zk Rollups such as @ zksync, Polygon zkEVM @ Starknet, etc. use incomplete validation, and zk proofs do not cover some complex EVM operations. Finally, I took another look at the official roadmap of Linea. The Linea mainnet has undergone over 10 version iterations since its launch. The current version that implements 100% Proven is Beta v2, and the next version Beta v3 is expected to be launched in mid July. The world has been suffering for a long time! Finally, let me ask, Wen?
