Blockchain platform Algorand (ALGO) has outlined a roadmap to make its network resistant to future quantum computer attacks, with native post-quantum accounts scheduled for 2026 and more extensive protocol upgrades continuing through 2027. The plan includes Falcon-based signatures, hybrid accounts, post-quantum multisignatures, and research into quantum-safe consensus and validator selection. The announcement comes as blockchain developers increasingly prepare for the long-term risks that quantum computing could pose to today’s cryptography.

Native Post-Quantum Accounts Arrive in 2026

According to the roadmap that the company shared on June 18, Algorand’s first major milestone will come in Q3 2026 with native support for post-quantum accounts built directly into the protocol. 

These accounts will initially use Falcon-1024, which extends the work that began with LogicSig-based Falcon accounts introduced in 2025. Though those earlier accounts proved post-quantum signatures could work on Algorand, they were not integrated into the ledger itself.

The same protocol release will also introduce network-level support for multiple signature schemes, allowing traditional Ed25519 accounts to coexist alongside post-quantum signatures. Algorand describes this as a key step toward “cryptographic agility,” enabling additional signature algorithms to be adopted later without requiring major protocol changes.

Beyond the protocol itself, the Foundation expects SDKs, AlgoKit, and Pera Wallet to support Falcon account derivation during the same Q3 2026 release window. Hardware wallet support will follow once the industry reaches agreement on a standardized post-quantum hierarchical deterministic wallet derivation method.

The roadmap also outlines support for hybrid accounts by the end of 2026, allowing users to combine classical elliptic-curve cryptography with post-quantum signatures. According to Algorand, these hybrid accounts aim to protect against both today’s conventional attacks and future quantum computers and give institutions greater flexibility for treasury management and high-value operations.

At press time on June 22, Algorand’s native token, ALGO, was trading at the price of $0.08966, which indicates a 3.3% decline on the day, a drop of 4% across the week, and a loss of 19.5% over the past month, per the latest chart data.

Multisignatures and Consensus Remain Active Research

Native future-proof multisignature accounts should also come out by the end of 2026. Instead of using scheme-specific threshold security, Algorand intends to build a more flexible policy layer capable of allowing weighted approvals, hybrid combinations of classical and future-proof signers, and future signature algorithms as standards evolve.

The Foundation is also continuing research into updating one of the chain’s most important cryptographic components: its Verifiable Random Function (VRF). Because the current VRF relies on elliptic-curve cryptography, researchers are evaluating quantum-resistant alternatives that preserve both efficiency and committee-selection privacy. A research paper describing a candidate design should arrive in early 2027, provided that ongoing security analysis is successful.

Meanwhile, Algorand is investigating post-quantum consensus signatures to replace the Ed25519 signatures currently securing validator messages. Falcon remains the leading candidate due to its relatively compact signatures, though the Foundation expects any migration to operate under a hybrid model for some time as both classical and post-quantum signatures run in parallel.

The roadmap also includes ongoing work on Falcon-512, expected later in 2026, alongside proof-of-concept implementations demonstrating Falcon-1024 signing on hardware wallets. According to the Foundation, current tests on a Trezor Safe 5 show signing takes roughly 0.7 seconds per transaction, suggesting post-quantum signatures are becoming practical even on constrained hardware.
