Algorand Foundation is making huge strides towards hardening their blockchain against any possible quantum computing threats. Centering the new roadmap around Q Day in 2027, that’s not coincidental – Algorand’s (ALGO) is poised to be ready to defend against quantum hazards from day one.
Native Accounts Broaden Falcon Signature Capabilities
“The question is no longer whether the transition to post-quantum security will happen. It’s whether organizations will be ready when it does”, – reads the Algorand Foundation’s official statement on X. With Falcon signatures already live on the mainnet, that’s a headstart that was specifically praised by Google in one of their recent papers on quantum computing.
The Falcon signature-enabled accounts were made via the LogicSig programs that the Algorand Virtual Machine (AVM) executes on behalf of an account. In the forthcoming Q3 protocol release, Algorand’s developer team is striving to make those accounts native.

Falcon accounts were not natively supported by the ledger, developer tooling, or consensus rules – now it will be.
On top of that, this Q3 2026 protocol release will introduce network-level support for multiple concurrent signature schemes. Algorand’s traditional Ed25519 will be continuously supported, while other signature options will be seamlessly implemented without further major structural overhauls. For this to happen, the devs are merging ECC-based accounts with lattice-based.
Key Changes In Algorand’s Core Mechanism By 2027
The primary principle is to set up a robust defense against both classical and post-quantum security risks. Once the new protocol upgrade kicks in, Web3 dwellers on Algorand (ALGO) will be able to create the fresh quantum-resistance crypto wallets inside the Pera Wallet, with the software kits natively supporting the revamp. Quantum accounts can also be used for staking.
Further on, Algorand Chief Scientific Officer Chris Peikert assured the Falcon-1024 will be supported by the new protocol immediately, while the more comprehensive Falcon-512 support is planned by year’s end. Notably, the key sizes are considerably larger than the traditional Ed25519 mechanism:
Last but not least, Algorand’s developer team is hammering away on the Verifiable Random Function (VRF) research paper. Slated for a full release in early 2027, this research underpins Algorand’s committee selection and the cryptographic sortition process. According to the current argument, the ECC-based VRF wouldn’t stand a real chance in terms of membership anonymity.
Therefore, the Algorand Foundation is working on a solution that would have a specific candidate construction. While the research is going on, Algorand’s likely to operate under a hybrid model for a while, where both Ed25519 and Falcon signatures will be used for consensus messages. The team will assess the security of the new scheme in parallel to its deployment.

Quantum computers are super powerful machines that could one day break the cryptography that protects Bitcoin, Ethereum, and most cryptocurrencies. This is called the “quantum threat.”
Algorand has released a roadmap to make its network quantum-resistant (also called post-quantum secure). This means they want to protect accounts and transactions from future quantum computer attacks.
These are special types of accounts on Algorand that will use new, stronger cryptography designed to resist quantum computers. Instead of the current system, users will eventually be able to create accounts that are quantum-safe by default.
Algorand already has some quantum-resistant technology live on the network. Their goal is to achieve broad quantum resilience across the whole ecosystem by year-end 2027.
