No single point of failure, which increases resilience to cyber-attacks and operational failures. However, it would also be subject to several cons: • • • • •  Slower release of goods and services due to slow confirmation of the payment. High energy use for validation, and relatively high fees for domestic payments.
Not scalable to large volumes of transactions due to the longer time taken to validate each block of transactions. Probabilistic finality—there is a very small chance that the transaction could be nullified if a malicious agent managed to change the blockchain. Reliance on crypto-currency exchanges for cross-border transactions which could be subject to cyber-attacks.
