Algorand CEO Urges Quantum Security Planning for Tokenized Finance

Algorand CEO William Herkelrath urged financial firms to build post-quantum security into tokenized markets, saying migration must span wallets, custodians, exchanges and hardware providers as well as blockchains.

“Quantum readiness should already be a key discussion point today,” Herkelrath wrote in an Oct. 21 post. The call puts operational systems and service providers alongside blockchain transaction security in the migration effort.

Post-quantum cryptography uses methods designed to withstand attacks from future quantum computers. Many major blockchains use elliptic-curve cryptography to authorize transactions. A sufficiently powerful quantum computer could use an exposed public key to derive its private key, though exposure varies by network and account design. A March 2026 resource calculation estimated that a modeled quantum computer could solve a 256-bit elliptic-curve problem in minutes, assuming hardware with fewer than 500,000 physical qubits. The estimate describes computing resources, not when such a machine might exist.

Algorand has added Falcon-based protections to parts of its network. State Proofs, introduced in 2022, use Falcon signatures to certify ledger state every 256 rounds, roughly every 12 minutes. Native Falcon-1024 accounts went live on mainnet in August 2026.

The network’s protections do not yet cover all operations. Its verifiable random function and consensus signing operations still rely on elliptic-curve cryptography and Ed25519, with post-quantum alternatives under study. Algorand targets broad quantum resilience by the end of 2027.

The G7 Cyber Expert Group issued a financial-sector migration roadmap in January 2026. The roadmap is nonprescriptive and does not set regulatory expectations. The National Institute of Standards and Technology (NIST) finalized three post-quantum standards in 2024: FIPS 203, 204 and 205. Falcon was selected for standardization, while its FIPS 206 standard remains in development.
