double spend

Phonetic: /ˈdʌbəl spɛnd/

Part of Speech: noun

Category: To be determined

The 'double spend' is the benchmark security concern of blockchain networks: how do we ensure that someone doesn't send the same transaction to two different entities, essentially 'spending their money twice'? This is the cornerstone of the consensus mechanism, ensuring that all nodes of the network are 'in agreement' about which assets are allocated to which addresses, on an ongoing basis, to prevent malicious actions such as a double spend.
