Quantum computers have just crossed a red line. When NIST approved three post-quantum encryption standards on August 15, 2024, it effectively started a countdown for each blockchain. Some teams haven’t waited: they are already delivering code signed with Falcon, Dilithium or XMSS keys. In this guide, you’ll discover five projects that have true post-quantum defenses and discover which path best fits your 2026 security roadmap.
Five quantum-resistant blockchain projects to watch in 2026
Quantum risk and new NIST standards trigger countdown for blockchain security migrations.
Quantum hardware is catching up with RSA and ECDSA keys. NIST highlighted this risk on August 15, 2024 by adding Dilithium, Falcon and SPHINCS+ to the registry of Federal Information Processing Standards.
The projects below are already signing or verifying data with at least one of these algorithms, giving you a handy shield well before the highly anticipated “Q Day”. Analyze their approaches, compare their strengths and decide which strategy fits your risk profile.
Project 11: a quantum safety net for Bitcoin
Bitcoin’s cryptography is notoriously difficult to upgrade, so the 11 Applied Quantum Computing Project created Yellowpages, an open source ledger that links a user’s current address to a post-quantum key without touching the base chain (raised $6 million from Variant, Quantonation and Castle Island).
Why it matters: On-chain research shows that about 6.36 million BTC, or about 33% of the supply, are in outlets where the public key is exposed, making them prime quantum targets. By registering proof of ownership today, you can claim these parts even if Shor-level machines appear tomorrow.
Overlapping Project 11 Yellow Pages links exposed Bitcoin outputs to post-quantum keys, creating a safety net before quantum attacks.
Project 11 simplifies the solution. Custodians install a command line tool (CLI) in minutes, without forks or wallet migrations.
According to Project 11’s Yellow Pages trust model documentation, the client generates new post-quantum key pairs from a 24-word seed phrase, links them to your existing Bitcoin addresses with signed messages, then wraps these proofs of ownership in a trusted execution environment before encrypting them with post-quantum ML-KEM so that they are not exposed to harvest-now-decrypt-later attacks.
The team is auditing NIST Dilithium, Falcon, and
Quantum Resistant Ledger (QRL)
QRL launched in 2018 as the first public chain secured by hash-based XMSS signatures, so every address has post-quantum protection from day one.
After seven years in business, the channel has never needed a security patch. The team recognizes XMSS tradeoffs: larger signatures and stateful “unique” keys that add friction to the wallet. These lessons are behind Project Zond, a Q4 2025 upgrade that will add stateless SPHINCS+ smart contracts and an Ethereum-style virtual machine, now running on a public testnet.
For node operators, the benefit is continuity. If a quantum attack happened tomorrow, QRL would continue to produce blocks on commodity hardware, without an emergency fork or wallet migration. Throughput today is around 70 TPS, and hashing-secured Layer 2 rollup is planned to increase capacity without reducing post-quantum guarantees.
In a space where “quantum ready” often remains on paper, QRL provides battle-tested code, public audits, and a clear path to quantum-secure DeFi.
QAN Platform
QANplatform offers quantum-ready Layer 1 with Dilithium signed accounts, full EVM compatibility, and private on-chain editing for on-premises use. Developers can deploy Solidity, Python, or Go contracts without rewriting them for new keys.
The project secured $15 million from MBK Holding in April 2024, funding audits and a public testnet launched the same month. In May 2025, an EU ministry began testing the QAN stack for critical infrastructure software, citing NIST alignment and local hosting options.
Architecture: a hybrid proof-of-stake network. Public validators manage the open chain, while permissioned clusters process up to 3,000 TPS internally, then anchor state to the public ledger with a single point of control to prevent data leaks.
Regulators are already calling for quantum migration plans; QAN has one that works today, with no upgrades required.
Algorand
Algorand proved post-quantum security at scale on November 3, 2025, by broadcasting the first mainnet transaction signed with Falcon-1024, a network-based signature chosen by NIST.
Algorand is the first major Layer 1 network to broadcast mainnet transactions signed with Falcon-1024.
Falcon already protects Algorand’s proofs of state, the compact certificates generated every 256 rounds that allow bridges and thin clients to verify chain history. Regular accounts still use Ed25519, but developers can create Falcon key pairs with an open source CLI and send quantum-secure transactions today without a protocol fork.
Next, the core team adds Falcon verification to the Algorand VM so that dApps and multisig wallets can adopt PQC with just two SDK updates instead of complete rewrites. With around 10,000 TPS and block times of 2.8 seconds, Algorand shows that speed and post-quantum security can coexist.
Hedera Hashgraph
Hedera’s 29-member board, which includes Boeing, Google and IBM, votes on every network upgrade and gives the ledger corporate-level control over changes.
On the cryptography side, Hedera anchors system identifiers with SHA-384, a hash length approved in the NSA’s CNSA 2.0 rules for Top-Secret traffic. In December 2024, Hedera partnered with semiconductor company SEALSQ to test the QS7001 secure chip. The chip stores post-quantum keys and signs transactions in tamper-proof silicon. The first production units are planned for 2025.
Why focus on hardware? Many regulated industries must use FIPS validated modules when updating cryptography. With QS7001, a bank can replace the board, reboot nodes, and adopt NIST standard Dilithium signatures as soon as the board approves them, without rewriting middleware.
If your compliance checklist requires both quantum-secure algorithms and auditable governance, Hedera clearly shows you the path from SHA-384 today to full Dilithium keys in the near future.
How do the contenders stack up?
Below is an overview of each project’s post-quantum posture as of January 2026. Use it to match technical suitability to your security goals.

Key takeaways
- Teams focused on compliance often choose Hedera or QANplatform.
- Incumbents looking for zero migration assurance tend to favor QRL or Project 11.
- If significant liquidity is essential, Algorand offers an immediate option.
Future prospects: standards in the day of migration
Quantum risk is now on the agenda of regulators, and no longer in science fiction novels. Europol’s Quantum Safe Financial Forum warned in February 2025 that banks should start inventorying vulnerable keys today, even though practical quantum attacks could be 10 to 15 years away. The US government has also ordered federal agencies to be “quantum resilient” by 2035.
Three forces will shape the next 24 months (January 2026 – December 2027):
Regulation, tools, and the economics of migration will determine how quickly blockchains evolve toward quantum-secure cryptography.
Regulations move forward first. Draft EU and US guidelines already require custodians to document quantum exposure; Once these drafts are turned into rules, exchanges will need audit trails showing keys protected by Dilithium, Falcon, or XMSS. The five projects in this guide also serve as an instant compliance checklist.
Tooling becomes commonplace. At least four Chrome Store wallets and two cloud-HSM providers have added post-quantum curves in 2025 alone. As browser extensions and hardware wallets adopt PQC by default, “wait and see” becomes a harder position to justify.
The economics of migration are the last to intervene. Millions of cold wallets, multisig contracts and dust addresses still use ECDSA. Expect bonuses and fee reductions, as well as Bitcoin’s possible PQ soft-fork, to woo laggards. Tools like the Project 11 Yellow Pages are already repeating this mass migration playbook.
Debate over deadlines fades; the new question is execution speed. The standards exist, the software is shipped and the regulatory clock is ticking.
Conclusion
The guide presents five practical paths to quantum-secure blockchain operations, each with distinct strengths. Align these options with your organization’s risk tolerance, compliance obligations, and technical roadmap to stay ahead of the quantum curve.
