Core idea: Different users jointly create a single Bitcoin transaction, which includes all user input. The main reason is that although the merger becomes a single transaction, the signatures of the two parties in the merger are independent of each other.
Since the order of the input and output addresses is random, the attacker cannot establish a matching relationship between input and output
Confirm that the output information is correct in the transaction, and the size of the input and output bitcoins match. Once confirmed, it will be signed
By fixing the size of the unit bitcoin transaction when transactions are conducted between different groups, the leakage of transaction information can be effectively avoided.
Implementation steps:
Find the counterparty who wants to mix the currency as a node.
Exchange input/output addresses.
Create a transaction.
Send this transaction to others, and each node will sign after confirming their output address.
Broadcast this transaction.
