That is strange – default passwords change per mining OS, so how would they know what OS was operating?

EVM is a runtime compiler to execute a smart contract. As soon as the code is deployed on the EVM, each participant on the community has a copy of the contract. When Elsa submits the work on Ethereum PoW fork for analysis, each node on the Ethereum network will consider and confirm whether the consequence given by Elsa has been performed as per the coding necessities.
