Algorand is urging financial institutions building around tokenization, stablecoins and blockchain settlement to treat post-quantum migration as an infrastructure requirement rather than a distant research problem. The Foundation argues that long-lived financial assets should not depend indefinitely on cryptographic assumptions that future quantum computers may invalidate, even though no known machine can currently execute such attacks at practical scale.
In an October 21 blog post, Algorand CEO William Herkelrath framed the issue around “cryptographic agility,” or the ability to replace signature schemes as security standards evolve. The objective is not to predict exactly when cryptographically relevant quantum computers will arrive, but to build systems that can change their security model without reconstructing the surrounding financial infrastructure.
That concern is particularly relevant to institutional blockchain deployments because custody systems, payment networks and tokenized assets can remain operational for years or decades. A migration that affects blockchains, wallets, exchanges, custodians and hardware devices requires coordination well before an existing cryptographic primitive becomes unsafe, making transition capability itself part of infrastructure risk management.
Algorand Builds Post-Quantum Migration Into Accounts
Algorand already operates several pieces of post-quantum infrastructure. Its State Proofs have used Falcon signatures since 2022 to provide quantum-resistant attestations of ledger history, while native Falcon-1024 accounts became available on mainnet through the Algorand 5.0 upgrade in August 2026.
Those account protections have moved beyond test environments. Pera Wallet has already recorded more than one million transactions from post-quantum Algorand accounts, providing production usage of Falcon-based authorization rather than simply a roadmap for future deployment.
The network is not fully quantum-resistant, however. Algorand’s roadmap still includes post-quantum multisignature support and research into quantum-resistant VRFs and signatures used for consensus messaging, with broader resilience targeted for the end of 2027. Existing Ed25519 accounts also remain supported alongside the newer Falcon account type.
This coexistence is central to the cryptographic-agility model. Algorand’s architecture is designed to support multiple signature schemes concurrently rather than forcing every account and application through a single immediate migration, allowing users and institutions to transition as tooling and security standards mature.
Quantum Readiness Expands Across Blockchain Networks
Algorand is not alone in preparing for a cryptographic transition. Sui recently executed its first native post-quantum transaction on devnet, using ML-DSA-65 for account authorization while retaining a separate path for hash-based vault protection. Sui’s implementation remains pre-mainnet, illustrating that post-quantum readiness is progressing at different stages across networks.
TRON has taken a similarly staged approach through post-quantum signature testing on Nile. Its architecture supports FN-DSA and ML-DSA alongside existing ECDSA, meaning the testnet deployment establishes migration capability without making current TRON mainnet accounts quantum-resistant.
Ethereum developers are also exploring ways to make post-quantum cryptography economically practical, including EIP-8288 and recursive proof aggregation. The variety of approaches shows that the industry has not converged on a single signature scheme or migration architecture, reinforcing the case for systems capable of adapting as standards develop.
NIST has reached a similar conclusion at the broader cybersecurity level, defining crypto agility as the ability to replace cryptographic algorithms across applications, software, hardware and infrastructure without disrupting operations. For tokenized finance, that means quantum readiness extends beyond the blockchain protocol to every component that holds, signs, transmits or authorizes digital assets.
Algorand’s argument is therefore less about an imminent quantum attack than about infrastructure lifespan. As banks and asset managers commit more capital and operational processes to blockchain systems, the ability to migrate cryptography without moving or rebuilding the financial system around those assets becomes a measurable security characteristic in its own right.
