A key platform advantage: the ability to precisely reproduce errors when systems fail, letting engineers quickly pinpoint issues. Notably, Ethereum leveraged Antithesis’ simulation technology for stress testing before upgrades—simulating extreme conditions to spot vulnerabilities ahead of its proof-of-stake
