Algorand v5.0.0 has reached 90% node support, clearing the upgrade for activation after its cooldown period.&nbsp;
The protocol change marks Algorand’s largest upgrade since staking rewards launched in January 2025. It introduces native post-quantum accounts alongside expanded smart contract capabilities and a flexible fee model.
The upgrade also moves <a href="https://blockonomi.com/algorand-sets-2027-deadline-to-become-fully-resistant-to-quantum-computing-threats/" rel="noopener noreferrer nofollow">Algorand</a> closer to a protocol designed to adapt as cryptographic standards evolve.

The Algorand team confirmed the 90% support threshold in a post on X. The upgrade will activate once the required cooldown period ends, with mainnet deployment expected soon.

 Algorand v5.0.0 has reached 90% support and will now activate after the cooldown period.
 This is the biggest upgrade since staking rewards, bringing native post-quantum accounts, more powerful smart contracts, and a more flexible fee model.

Algorand v5.0.0 introduces native Falcon-1024 accounts for <a href="https://blockonomi.com/tron-post-quantum-signatures-launch-on-nile-testnet-after-vote/" rel="noopener noreferrer nofollow">post-quantum</a> signatures. The change moves quantum-resistant account support directly into the protocol rather than limiting it to application-level tools.
The upgrade also introduces AVM v13, expanding smart contract sizes and adding new functionality. New opcodes include poseidon2, while cross-application box storage support expands how applications can manage data.
Algorand has already developed post-quantum infrastructure through earlier network upgrades and account implementations. <a href="https://x.com/MarcoSalzmann80/status/2088814022938312741?s=20" rel="noopener noreferrer nofollow">According</a> to X user Marco Salzmann, v5.0.0 shifts that effort toward broader cryptographic agility across the protocol.

The new release adds a per-byte fee model for larger transactions and computationally heavier operations. Standard transfers will not face the same fee changes under the new structure.
The model gives Algorand more flexibility when transactions require greater storage or computational resources. It also creates a mechanism for fees to reflect transaction size&nbsp; without changing ordinary transfer costs.
Algorand community member Alex, known as france.algo on X, said thousands of node runners upgraded within days. His post described v5.0.0 as one of the network’s largest <a href="https://coincentral.com/pi-network-moves-into-critical-stage-with-dex-debut-and-protocol-upgrades/" rel="noopener noreferrer nofollow">protocol upgrades</a>.

Salzmann also outlined a broader roadmap involving hybrid accounts, post-quantum multisig and additional Falcon research. The roadmap includes further work on post-quantum verifiable random functions and consensus mechanisms.
