Aspects of the disclosure relate to methods, systems, and apparatuses for improving speed of transaction processing in payment systems using a proof of cache system. The proof of cache system may be used to validate transactions using cached keys stored on Directed Acyclic Graph (DAG) nodes that are available. The cached keys may be encrypted using Argon2d cryptographic hashing.
