Some or all Proof of Stake models choose which node to give the right to create a token/coin based on randomness (the more tokens you have, the higher your chances of being chosen). Example: Cartesi (CTSI): https://www.coingecko.com/en/coins/cartesi
“Node runners are selected randomly according to a PoS system and gain the right to create the next block.”
Does this make this specific PoS haram? Or is this how all PoS work? Is randomness in a financial system halal?
