The wallet creation with monero-wallet-cli results in a seemingly random mnemonic seeds and wallet address. Since the result of any computer program is deterministic and thus relies on an external random state to create true randomness - what mechanism creates the entropy for Moneros wallet creation algorithm?
Imagine I set up two computer systems with identical hardware (lets assume I can do this, ie. that there is a fabrication line that is able to produce identical parts). Lets assume further that these machines share one connection to the outside world, ie. input devices and power cables. I shall start them at the same time (in a relativistic sense, that is their CPU clocks are running synchronously). Will the wallet creation on these two systems result in the same wallet?
