Algorand climbed more than 44% over the past week after Google's quantum computing research team explicitly cited it as a working example of post-quantum cryptography deployed on a production blockchain.

What Google Said

In the whitepaper "Securing Elliptic Curve Cryptocurrencies against Quantum Vulnerabilities," published on March 31, Google Quantum AI researchers — alongside collaborators from UC Berkeley and the Ethereum Foundation — mapped the quantum threat to major blockchain networks. Among the chains they evaluated, Algorand was called out as providing "an example of real-world deployment of PQC on an otherwise quantum-vulnerable blockchain."

The paper highlighted Algorand's use of Falcon digital signatures for smart contracts and state proofs. Algorand executed its first PQC-secured transaction in 2025 and supports native key rotation, allowing a future migration path to full quantum security as standards mature. The chain also hosts USDC specifically because its infrastructure supports post-quantum digital signatures.

Market Reaction

ALGO jumped roughly 13% in a single day to around $0.12, extending a 44% weekly gain according to CoinGecko data. Leo Fan, founder of Cysic and a former lead on quantum resilience at Algorand, attributed the move directly to the paper's citation: "Algorand stands out because it has post-quantum signature schemes like Falcon live on the mainnet and was specifically referenced in the paper, giving it strong technical and narrative momentum."

The Broader Context

The Google paper estimates that a quantum computer with fewer than 500,000 physical qubits could eventually break the elliptic curve cryptography securing most blockchain wallets — a 20-fold reduction from prior estimates. While no machine capable of the attack exists today, the research has focused the industry on which networks are actually prepared. Algorand's head start gives it a rare position: a blockchain Google is pointing to as already doing the work.
