The script picks pseudo-random Ethereum winner account from the list using native blockchain randomness source - the blockhash on the given block height.

It uses the “Mersenne Twister” deterministic 623-dimensionally equidistributed uniform pseudorandom number generator, one of the most extensively tested randomizers in existence.

• Block: 12362727 on Ethereum Mainnet #1
• Estimated Target Date: Mon May 03 2021 17:58:29 GMT
