  Algorand's consensus algorithm ensures security and scalability in digital currencies through its unique approach called Pure Proof-of-Stake (PPoS). By randomly selecting a small group of users as validators for each block, Algorand achieves security by preventing any single entity from gaining control over the network. This randomness also ensures scalability, as the algorithm can process a large number of transactions simultaneously without sacrificing security. Additionally, Algorand's consensus algorithm uses cryptographic techniques to ensure the integrity and immutability of the blockchain, further enhancing security in digital currencies.
