Algorand's ALGO token fell around 10% this week and approached USD 0.10 as the network advanced its post-quantum security work. The price decline put nearby support in focus, while Algorand confirmed a rekeying feature that lets users switch to Falcon-1024 signatures without changing account addresses or moving assets.
More than 2,000 native post-quantum accounts have signed transactions on its mainnet. Even so, the network has not yet extended quantum-resistant protection to every part of its protocol.
The two developments place different questions before market participants. ALGO faces a near-term test around USD 0.10, while the blockchain continues a longer shift toward stronger cryptographic safeguards. Its foundation aims to achieve broad quantum resilience by the end of 2027.
ALGO's roughly 10% fall brought the token close to USD 0.10 during the week. That level now forms the main reference point in the market outlook, with attention on whether selling pressure slows or continues into the following week.
The price move came as institutional engagement and technical pressures drew attention. Yet the available information does not establish that Algorand's security announcement caused the decline. Nor does it provide a 24-hour volume figure to measure the strength of activity behind the move.
Consequently, the near-term picture remains tied to price behavior rather than a confirmed response to the protocol update. Market participants are watching whether selling pressure weakens in the next week as ALGO approaches the USD 0.10 area.
Algorand's new rekeying capability allows an account to adopt Falcon-1024 signing while keeping its original public address. Users also retain their transaction records and assets, removing the need to transfer holdings into a replacement account for this change.
That distinction matters for account management. Instead of moving assets and rebuilding account history, a user can update the signing method linked to an existing address. The feature offers a path to stronger protection against future quantum threats without altering the account's visible identity.
The network reports that more than 2,000 native post-quantum accounts have signed mainnet transactions. This figure shows that Falcon-based account activity already exists, although it does not establish how many users have adopted the newer rekeying option.
Algorand had already tested related technology before this upgrade. On November 3, 2025, its mainnet processed its first quantum-resistant transaction using a Falcon logic-signature template. The step expanded practical uses of the signature scheme beyond its earlier application.

Algorand introduced state proofs in 2022. These compact certificates attest to the ledger's state every 256 rounds and use Falcon signatures. They provide an earlier example of post-quantum cryptography operating within the blockchain.
Still, users do not receive universal quantum protection by default. Standard transactions continue to use Ed25519, and the consensus-layer verifiable random function remains based on classical cryptography. How much of Algorand's network does its post-quantum security cover today?
A review by Nervos described live state proofs and Falcon verification while placing native account support and consensus-related changes on the roadmap. Algorand's reported account developments indicate progress on account-level protection, although the wider consensus work remains unfinished.
On June 18, the Algorand Foundation published a roadmap targeting broad quantum resilience by the end of 2027. Technology chief Bruno Martins' explanation that planned updates seek to extend protection across the network.
The work also sits within an industry-wide effort to prepare for advances in quantum computing. Reuters reported that the Ethereum Foundation is targeting 2029 for full quantum protection. For Algorand, upcoming milestones concern remaining cryptographic systems as well as the use of its new account features.
ALGO approached USD 0.10 after a weekly decline of about 10%, while Algorand expanded access to Falcon-1024 signing through account rekeying. More than 2,000 post-quantum accounts have signed mainnet transactions, but standard transactions and consensus cryptography retain classical components. The foundation targets broader quantum resilience by the end of 2027.
