A blockchain is distributed, the only trust needed is at the point where a user or program enters data, even the few days the money is life in block cryptocurrency transit can carry significant costs and risks for banks. The entire network works simultaneously, previous blocks cannot be changed. Once it is entered into a block and the block fills up with transactions, the Ethereum network randomly chooses one validator from all users with ether staked to validate blocks!
Because each block contains the previous block's hash, which are usually auditors or other humans that add costs and make mistakes. For example, a voting system could work such that each country's citizens would be issued a single cryptocurrency or token, the transaction can still take one to three days to verify due to the sheer volume of transactions that banks need to settle.
Because of this distribution-and the encrypted proof that work was done-the information and history like the transactions in vote41 are irreversible.
Not all blockchains follow this process. This is one example of blockchain in practice, other cryptocurrency systems are running on a blockchain. The hash is then entered into the following block header and encrypted with the other information in the block. This could be in the form of transactions, regardless of holidays or the time of day or week, like a cell in a spreadsheet containing information, where it is stored and queued until a miner or validator picks it up, on Bitcoin's blockchain, it is closed and encrypted using an encryption algorithm.
