Double Spend

A blockchain fork created when a user sends the same blockchain assets to two different entities. These forks are prevented by consensus mechanisms put in place to verify and record transactions in order to maintain the integrity of the blockchain. In theory, if a malicious entity were to gain control of more than 50% of network miners or validators, transactions that would otherwise be considered invalid could be pushed through.
