Algorand Specifications

Algorand uses the SHA-512 algorithm to strengthen post-quantum security by increasing collision resistance against Grover’s algorithm.

In Algorand, the SHA-512 algorithm is used to:

• Compute an additional hash of the previous Light Block Header (prev512) (see Ledger normative specification),
• Generate an additional commitment (txn512) of the transactions included in the block ( payset) (see Ledger normative specification).
