Algorand this week laid out a roadmap to make its blockchain resistant to quantum computing attacks by 2028. The plan, which the foundation described in a technical post, calls for changes to both user wallets and the core protocol itself. It's a long-term bet that quantum computers powerful enough to break current cryptography could arrive before the decade is out.
The timeline
Algorand is targeting 2028 for full quantum resistance. That's a two-year window from now — and the crypto industry broadly recognizes that implementing these upgrades takes time. The roadmap doesn't offer a specific quarter or month, just the year. But laying out the deadline this early gives developers and wallet providers a clear target to work toward.
What has to change
The upgrade touches two layers. On the wallet side, users will eventually need to migrate to new addresses that use quantum-resistant signature schemes. On the protocol side, Algorand plans to swap out the underlying cryptographic primitives — the mathematical functions that secure transactions. That means a hard fork or a coordinated network upgrade. The foundation hasn't detailed which specific algorithms it will adopt, just that they'll be post-quantum standards.
Why now
Algorand isn't alone in thinking about this. Other chains like Ethereum and Bitcoin have research projects on quantum resistance, but none have set a public deadline. The timing of this announcement — mid-2026 — suggests the network wants to get ahead of the conversation, not scramble later. There's no immediate threat; no quantum computer today can break elliptic curve cryptography. But the lead time for rolling out changes across thousands of nodes and millions of wallets is measured in years, not months.
The open question
Migrating users onto new addresses is the trickiest part. Wallet software, exchanges, and dApps all need to support the new scheme. Algorand's roadmap acknowledges that adoption could take years after the protocol itself is ready. Whether the community moves fast enough — and whether 2028 turns out to be early or late — is the unresolved bit. The foundation says it will publish more technical specs later this year.
