Algorand is the latest blockchain project to set out its stall for Q-Day, the point at which quantum computers could break the cryptography securing cryptocurrencies.

On Thursday, the layer-1 project announced a roadmap to make its blockchain resistant to future quantum-computing attacks by the end of 2027, including quantum-resistant accounts based on post-quantum digital signature system Falcon. Also on the cards is a quantum-resistant replacement for the system that generates the randomness used to select validators, and alternatives to signatures.

The project joins a growing list of crypto platforms preparing for a post-quantum world, including Stellar, Ethereum and, of course, Bitcoin. Back in April, Algorand soared after being cited in a Google research paper on post-quantum protocols, indicating that investors increasingly view quantum resistance as a must-have rather than a nice-to-have.

Q-Day is coming into sharp relief outside the blockchain space, too, with France gearing up to stop certifying security products that lack quantum-safe encryption from next year.

Algorand Plans to Be Ready for Quantum Computing Threat by End of 2027

Quantum computing threatens the blockchain ecosystem, from Bitcoin to Ethereum and beyond, and Algorand has a plan to be prepared.

Will Base TGE in 2026?
YES 32%68% NO
  
Why it matters
Coinbase unveiled its "everything exchange" roadmap Tuesday—tokenized stocks with automatic dividends, options trading, Coinbase One Card travel rewards, and a Solana lending product—with no mention of a Base token, per Decrypt. The Base Beryl protocol upgrade announced Thursday focused on technical improvements, not tokenomics. Both moves reinforce the long-held view that Coinbase isn't breaking its token-free posture this year. NO climbed from 61% to 68% since Monday.
