Everything on the Blockchain is transparent and nothing can be hidden, or that’s what you may think. I bet most people think money laundering on the Block isn’t possible, well, it’s very much possible.
There has been news in the past about “X paid 1k in ETH fees, or X made a mistake and paid a lot of BTC transaction fees”. Most likely, they did not lose anything, because that weren’t mistakes and here’s why. The miners/mining pools help money laundering on the blockchain. That’s the reason why the transaction fee can be way more than the actual transaction amount if you were wondering.
Money laundering can be done only on a PoW(proof of work) network. A miner would select a transaction with high fee and place it into a Block, followed by solving the block and the network confirming the transaction. The Transaction fee will not disappear, it will be picked up by the miners that solved the block. In other words, the miner/s will receive the money that the sender sent by increasing the transaction fee. This method is a very good one to hide the source of funds.
One could do this with his own mining equipment. There is no need to race with other miners since the Block will be mined before the tx is made. The transaction is not broadcasted publicly before is confirmed, therefore others can’t take part in the mining.
