Career attack

The Race Attack is a type of duplicate spending that affects Bitcoin merchants or users who accept payments without confirmation. Basically this attack is that the attacker makes a payment to a merchant with some coins and at the same time carries out another transaction with these coins to send them to another address that he controls. By manipulating the commissions of both transactions (lowering the commission of the first and increasing the commission of the second), these types of attacks can be more likely to succeed. Especially when the mempool is overloaded and miners only prioritize transactions with higher fees.
