Quantum‑Proof Blockchain: 7Block Labs’ Research Highlights

-- Pain --

You’ve got Solidity systems running in production, ZK-enabled plans in the works, and vendor contracts based on elliptic-curve cryptography (like secp256k1 and BLS). At the same time, post-quantum cryptography (PQC) has gone from a theoretical concept to being standardized and making its way into the web/TLS stack that your nodes and APIs are already using. Here’s what you need to know:

• On August 13, 2024, NIST officially wrapped up FIPS 203 (ML‑KEM), FIPS 204 (ML‑DSA), and FIPS 205 (SLH‑DSA). Following that, FALCON is on deck as FN‑DSA (FIPS 206), and back in March 2025, HQC was chosen as a backup KEM for ML‑KEM. If you haven't mapped all of this to your ledger, custody, and key-management processes yet, you might already be lagging behind your infrastructure vendors. You can check out more details on this at nist.gov.
• Your favorite browsers and cloud services are making some big moves: Chrome has switched from using Kyber for hybrid TLS to ML‑KEM768+X25519 (with a shiny new codepoint of 0x11EC), and AWS KMS/ACM endpoints are now supporting ML‑KEM hybrid PQ‑TLS--saying goodbye to earlier Kyber drafts. PQ‑TLS isn't just a trial anymore; it’s become a must-have for procurement. Check out the full scoop over at security.googleblog.com.
• For our friends in the U.S. public sector, the timelines are getting serious (CNSA 2.0/NSM‑10). Starting in 2027, “new acquisitions must be PQC‑capable,” with full NSS enforcement kicking in during the early 2030s. And even if you're not a federal contractor, expect your partners and auditors to want a roadmap and inventory from you. You can get more info at nsa.gov.

Here’s the scoop on the implementation rub within your EVM estate: classical signatures clock in at around ~3k gas for verification. On the flip side, if you’re looking at post-quantum signatures like ML-DSA, Falcon, or Sphincs+, and you try to verify them naively in Solidity, you’re talking about gas costs that can balloon from hundreds of thousands to even millions. Some real-world tests show that optimized Dilithium verification hits about ~6.6M gas--which is a big no-go for production EOAs. (github.com)

Agitation

Agitation is a term that encompasses a range of feelings, often related to anxiety or restlessness. It’s that intense inner turmoil that can make it hard to sit still or concentrate. If you've ever felt like your mind is racing or your body is on high alert, you know what I mean.

What Causes Agitation?

There are quite a few factors that can trigger feelings of agitation:

• Stressful Situations: Everyday pressures, whether at work or home, can pile up and lead to agitation.
• Mental Health Issues: Conditions like anxiety disorders, depression, and ADHD often come with this unsettling feeling.
• Substance Use: Caffeine, drugs, or even withdrawal from certain substances can ramp up feelings of agitation.
• Physical Health: Illness or discomfort in the body can also contribute. Think about how a headache can throw off your whole day!

Recognizing Symptoms

So, how do you know if you're feeling agitated? Here are some common signs:

• Restlessness: You might find it hard to sit still or relax.
• Irritability: Little things that wouldn't normally bother you start to get under your skin.
• Racing Thoughts: Your brain feels like it's on fast-forward, making it tough to focus.
• Physical Tension: You might notice tightness in your muscles or a constant need to move.

Coping Strategies

When agitation strikes, try these tips to find some relief:

1. Deep Breathing: Take a moment to breathe deeply. Inhale for a count of four, hold for four, and exhale for four.
2. Get Active: Go for a walk or do some light exercise. Movement can really help shake off restless energy.
3. Mindfulness: Consider practicing mindfulness or meditation. Just a few minutes of focused breathing can make a world of difference.
4. Talk it Out: Sometimes, sharing what’s on your mind with someone you trust can lighten the load.
5. Limit Stimulants: If you're feeling particularly agitated, consider cutting back on caffeine or other stimulants.

When to Seek Help

If your agitation becomes overwhelming or starts to interfere with your daily life, it might be time to talk to a professional. They can help you figure out what’s going on and suggest effective treatments.

For more info, check out these resources:

• Mental Health America
• National Institute of Mental Health

Remember, it’s okay to feel agitated now and then. Acknowledging it is the first step toward finding your calm.

If you overlook this transition, you could end up facing unnecessary outages, scrambling for emergency hot-patches, and needing to renegotiate contracts:

• Delivery risk: Vendor stacks are already evolving with new cipher suites, like Chrome’s ML‑KEM and AWS’s ML‑KEM endpoints. If your gateway, signer, or custody integrations get stuck on outdated Kyber versions or rely solely on traditional TLS, you could face silent downgrades and tricky interoperability issues in production. That could lead to unexpected downtime and some not-so-great audit results. (security.googleblog.com)
• Budget risk: If you're verifying PQ signatures "on-chain the hard way," be prepared for a serious hit to your budget--it’s about three times more costly than ECDSA. At 6.6M gas per verification, even just 50k monthly authorizations could eat up funds and drag down user experience--definitely not what you want when your product needs to show it can scale. (github.com)
• Compliance risk: CISA, NSA, and NIST are all pointing organizations toward keeping a solid cryptographic inventory and a clear migration plan. Without an up-to-date inventory and some crypto-flexibility, SOC 2 auditors--and those public-sector buyers--are likely to flag you with an “insufficient roadmap” for PQC. (cisa.gov)
• Strategic risk: A lot of current ZK systems depend on pairings (think SNARKs). Those number-theoretic assumptions are prime targets for Shor’s algorithm. On the other hand, STARKs use collision-resistant hashes and can handle bigger hash sizes, making them more resilient. If you don’t have a STARK-first strategy, your “privacy/scale” story might need a serious overhaul when the pressure’s on. (starkware.co)

7Block Labs’ Methodology

At 7Block Labs, we’ve got a unique approach to quantum-proofing that really connects the dots between Solidity, ZK engineering, and outcomes you can count on. We’re talking about things like SOC 2 compliance, impressive RFP win rates, and keeping an eye on total cost of ownership.

1) Baseline the Cryptography You Actually Run

First things first, you need to take a good look at the cryptography you’re currently using. It’s super important to understand what’s in place before making any changes or improvements. This means taking stock of all the algorithms, keys, and protocols you have in action. Here’s how to get started:

• Identify your current algorithms: Look at what you’re using for encryption and hashing. Are you going with AES, RSA, SHA-256, or something else? Make a list of them.
• Check key management practices: How are you handling your keys? Are they generated securely, stored safely, and rotated regularly? This is a key area where things can go wrong!
• Review your protocols: What’s the scoop on your communication protocols? Are you using HTTPS, TLS, or something outdated? Ensure you’re not running anything that might put your data at risk.

Taking the time to baseline what you have not only helps in identifying weak spots but also sets the stage for any upgrades or new implementations down the line. It’s a crucial step in fortifying your cryptographic practices!

We kick things off with a cryptographic SBOM and a threat model covering:

• Keys and Signatures: We're dealing with secp256k1 for everyday accounts and custody, BLS for rollups and aggregation, and Ed25519 for our infrastructure needs.
• Protocol Surfaces: Think about L1 transactions, rollups and bridges, oracles, off-chain signing, and CI/CD signing.
• Transport: We use TLS to secure communication between nodes, custodians, order flow relays, and data providers.

Deliverables will feature a PQC-mapping that highlights a few key points: first, how ML-KEM (FIPS 203) takes the place of ECDH in transport; next, where ML-DSA or FN-DSA can slide in behind account abstraction; and finally, where SLH-DSA (hash-based) is the go-to choice for firmware and code signing. You can check out more details here.

2) Architect for Crypto-Agility, Not a “Big Bang” Cutover

When it comes to implementing crypto solutions, it's way smarter to focus on crypto-agility rather than planning a massive, all-at-once cutover. Here’s why:

• Flexibility is Key: Crypto-agility means your systems can adapt to changes in cryptographic algorithms and standards without a total overhaul. This flexibility makes it easier to stay ahead of security threats and comply with new regulations.
• Gradual Implementation: Instead of ripping out everything and starting fresh, you can roll out changes gradually. This reduces risk and allows for a smoother transition.
• Minimized Downtime: A “big bang” approach often leads to long downtimes, which can be disruptive. By adopting a more agile strategy, you can keep services running while you make updates.
• Easier Testing: With a gradual approach, you can test each change independently to ensure everything works before moving on to the next one.
• Cost-Effective: Spreading out the changes can also be more budget-friendly, as you won’t have to allocate a huge sum all at once for a complete system replacement.

By thinking ahead and planning for crypto-agility, you not only enhance your system's security but also make your life easier in the long run!

• Account Abstraction (ERC‑4337): We're looking at this cool feature that lets us swap out signature schemes. Right now, our smart accounts can check ECDSA signatures, but soon we’ll be able to use ML‑DSA/Falcon, making it a breeze to transition users without needing to change the consensus. This is fast becoming the go-to way to set up custom verification logic. (ercs.ethereum.org)
• ZK as a cost-saver for Post-Quantum (PQ): Instead of going through the hassle of verifying a hefty 6.6M-gas Dilithium signature directly in Solidity, we handle this off-chain. We just submit a STARK proof that says, “Yep, PQC verification for message M and key K went smoothly.” On-chain, we only need to verify that proof once, which costs around 500-770k gas, depending on the circuit. This way, we avoid those wild gas surges per transaction and stick with proof systems that play nice with post-quantum challenges. (github.com)
• PQ‑TLS at the edges: We're beefing up our node RPC, custody connections, and CI/CD artifact fetching using ML‑KEM hybrid TLS. This way, we’re less likely to face a “harvest-now-decrypt-later” situation come 2029. AWS KMS/ACM/Secrets Manager already support ML‑KEM hybrid handshakes, and with Chrome’s shift to ML‑KEM, we’re cutting down on interoperability headaches. (docs.aws.amazon.com)
• STARK-first ZK roadmap: We’re making STARK provers and verifiers a priority for our privacy and scalability features. This strategy helps us sidestep any future issues from pairing-based SNARKs in a quantum world. For places where SNARKs are already in use, we’re planning migration windows and hash-size adjustments to stay ahead. (starkware.co)
• Precompile watchlist and L2 preference: We keep an eye on EIP proposals for Falcon/Dilithium precompiles, as well as favor L2s that roll out PQ precompiles earlier. This approach helps cut down both gas costs and transaction delays for PQ verification. And when precompiles aren’t an option? Well, we’ve got AA+STARK to keep things running smoothly. (eips.ethereum.org)

3) A Real-World Example: Launching Post-Quantum Wallets Without Breaking the Bank on Gas Fees

When it comes to rolling out post-quantum wallets, there’s a lot to consider--especially if you want to avoid those pesky gas fees that can add up quickly. Let’s break down how you can make this happen effectively.

Step 1: Choose the Right Blockchain

The first thing you’ll want to do is pick a blockchain that offers lower transaction costs. Some options to explore include:

• Polygon: Known for its low fees and fast transactions.
• Solana: Offers incredibly fast speeds with minimal costs.
• Binance Smart Chain: A popular choice with a solid balance of speed and affordability.

Step 2: Optimize Your Code

Next up, make sure your code is as efficient as possible. Here’s where a little optimization can go a long way. Here are some tips:

• Minimize Smart Contract Size: The smaller your contract, the fewer resources it will use, which translates to lower gas fees.
• Batch Transactions: Instead of sending multiple transactions separately, combine them into a single transaction whenever possible to save on costs.

Step 3: Test Thoroughly

Before going live, put your wallet through its paces with some rigorous testing:

1. Simulate Transactions: Use testnets to mimic real-world transaction scenarios without spending any actual funds.
2. Use Gas Estimation Tools: These can help you forecast costs before executing transactions. Tools like Etherscan can be really helpful here.

Step 4: Monitor and Iterate

Once your post-quantum wallet is up and running, keep an eye on performance and gas fees:

• Track Transactions: Tools like EthGasStation provide real-time updates on gas prices.
• Be Ready to Pivot: If gas prices spike unexpectedly, be prepared to adjust your strategy on the fly.

Conclusion

Productionizing post-quantum wallets doesn’t have to be a costly endeavor. With the right blockchain choice, optimized code, thorough testing, and constant monitoring, you can roll out your wallet without burning a hole in your pocket due to gas fees. Happy developing!

Goal: Move a VIP Group of Users to a PQ Smart Account in 90 Days

Our mission is to successfully transition a select group of VIP users to a PQ smart account within the next 90 days. Let's make this happen!

• Step A: We kick things off with a smart account that has dual-control verification (using ECDSA and ML-DSA). During the migration phase, users will sign using both keys, and once we've got enough ML-DSA coverage, we switch to “either-of” mode. The cool thing is that ERC-4337 allows us to do this without needing any changes to L1 consensus. Check it out here.
• Step B: Next up, we're stepping into off-chain PQ verification paired with on-chain STARK proof. We’re using Dilithium and Falcon for verification in a prover service and sending a proof to the contract’s validateUserOp. Once we’re in production, this setup helps keep verification gas pretty close to what you’d expect for typical ZK-verify costs (around 0.5-0.8M gas these days), instead of the hefty ~6.6M. You can learn more about it here.
• Step C: Finally, we’re toughening things up with ML-KEM hybrid TLS for custody and node RPC. Our change-control measures include TLS cipher policies, service level objectives (SLOs), and rollbacks if needed. Plus, AWS KMS is already on board with ML-KEM and has clear timelines for phasing out the older pre-standard Kyber. For more details, head over here.

4) Aligning Procurement and Compliance

When it comes to procurement, making sure everything aligns with compliance is crucial. Here are a few key points to consider:

• Understand Regulations: It’s important to stay up-to-date on relevant laws and regulations that affect your procurement processes.
• Standard Operating Procedures: Draft clear SOPs that reflect compliance requirements. This helps in keeping everyone on the same page.
• Regular Training: Offering regular training sessions can help your team stay informed about compliance changes and best practices.
• Monitoring and Reporting: Implement a system for tracking compliance and procurement activities. This can help you spot any issues before they become bigger problems.
• Collaborate with Legal: Partnering with your legal team can ensure that contracts and procurement policies meet compliance standards.

Remember, keeping procurement and compliance in sync not only saves you headaches later but also builds trust with your stakeholders.

• SOC 2-Friendly Controls: We’ve got everything covered, from cryptographic inventory and key rotation policies to TLS cipher governance, change management, and continuous monitoring--all ready to go for your audit evidence binder.
• Public-Sector Readiness: We’re on top of the CNSA 2.0 timeline (with new acquisitions needing to be PQ-capable by 2027 and full enforcement rolling out in the early 2030s). Plus, NIST FIPS adoption is factored into our vendor requirements and acceptance criteria. Our deliverables include a straightforward “PQC Migration Plan,” which aligns with CISA/NSA guidance.

What the Latest Data Says--and How We Turn It Into Business Success

Data is everywhere, right? But what does all this information mean for your business? Let’s dive into the latest findings and see how we can translate them into real outcomes.

The Key Findings

1. Consumer Behavior Shifts: Recent studies show that consumers are increasingly looking for personalized experiences. This means businesses need to adapt their strategies to meet these evolving desires.
2. Technology Adoption: There's a notable rise in the use of AI and automation tools. Companies that embrace these technologies tend to see improved efficiency and productivity.
3. Sustainability Matters: More than ever, customers are prioritizing sustainability. A significant portion of consumers are willing to pay more for eco-friendly products, pushing businesses toward greener practices.

Turning Data Into Action

Now that we've got a grasp on the latest data, it’s time to think about how to put this knowledge to work. Here’s how we can translate those insights into tangible business outcomes:

• Personalization: Use customer data to offer tailored experiences. This could mean personalized marketing campaigns or customized product recommendations, ultimately leading to higher engagement and sales.
• Embrace AI: Integrate AI tools into your operations. Whether it’s for customer support or streamlining logistics, leveraging these technologies can free up resources and enhance service quality.
• Focus on Sustainability: Adjust your product lines or services to include sustainable options. Promote these initiatives through your marketing to attract eco-conscious customers who are ready to support your brand.

Wrapping Up

The key here is that data isn’t just numbers and graphs; it tells a story that can shape your business strategy. By understanding the latest insights and acting on them, you're not just keeping up--you're setting yourself up for future success.

• Standards are final: The ML‑KEM (FIPS 203), ML‑DSA (FIPS 204), and SLH‑DSA (FIPS 205) have officially been approved! FALCON is getting ready for launch, and HQC is on standby as a backup KEM. Your vendors are currently gearing up for these algorithms, so there’s no waiting for the quantum wave to hit. We're syncing up your roadmap to ensure everything from audits to RFPs and partner questionnaires goes smoothly. (nist.gov)
• Web and cloud are shifting to ML‑KEM: Chrome has updated its codepoint to 0x11EC! AWS KMS/ACM is rolling out ML‑KEM support across the board (including those FIPS 140‑3 endpoints) and will soon be retiring the pre‑standard Kyber. Your TLS policy will now serve as solid proof in SOC 2 and vendor risk assessments. (security.googleblog.com)
• Gas economics are looking better with ZK: Running naive Dilithium on EVM at around 6.6M gas isn’t really practical, but using a STARK proof brings verification down to the comfy range of ~0.5-0.8M gas, which is what you’d expect from modern verifiers--an impressive 85-92% cut compared to on-chain PQ verification, while still keeping up with post-quantum standards. This is where you see the leap from “just research” to “production-ready.” (github.com)
• Choosing the right ZK matters: Pairing‑based SNARKs are built on number‑theoretic assumptions that Shor's algorithm could shake up; meanwhile, STARKs depend on hash security and are considered quantum-resistant, especially with larger hash sizes. By prioritizing a STARK-first approach, we’re avoiding the hassle of another migration down the line. (starkware.co)
• Government migration timelines are ticking away: CNSA 2.0 is aiming for new PQ-capable acquisitions by 2027, with broad enforcement starting in the early 2030s. CISA/NIST suggest you take stock and create roadmaps now. We’ll translate that into the procurement language you need and make sure everything is in check. (safelogic.com)

Implementation Blueprint (90‑Day Pilot → 12‑Month Rollout)

---

This blueprint serves as a guide for our rollout plan, starting with a 90-day pilot before expanding into a full 12-month implementation. Here's how we'll tackle this step-by-step.

Phase 1: 90-Day Pilot

The 90-day pilot will allow us to test our strategies in a manageable setting. Here’s what we’ll focus on:

• Objectives: We’ll identify key goals that we want to achieve during this phase.
• Key Activities:
  • Conduct workshops and training sessions.
  • Gather feedback from users to refine our approach.
• Metrics: We’ll track progress with specific KPIs to measure success.

Timeline

• Month 1: Kick-off and initial training
• Month 2: Implementation and feedback collection
• Month 3: Evaluate results and make adjustments

Phase 2: 12-Month Rollout

After the pilot, we’ll transition to the full rollout, ensuring that we’ve learned from our initial phase. Here’s how we’ll do it:

• Scaling Up: We'll expand to more teams and departments.
• Continued Training: Ongoing education and support will be crucial.
• Feedback Loops: Regular check-ins to gather insights and make improvements.

Timeline

• Months 4-6: Gradual implementation across teams
• Months 7-9: Full training and integration
• Months 10-12: Review and optimize based on feedback

Conclusion

We’re excited to see this plan come to life! With the lessons learned from our 90-day pilot, we’ll make the 12-month rollout successful and impactful. Let’s get started!

Pilot (Days 0-90): Measurable, Low-Risk, SOC 2-Aligned

• We’ve got a Cryptographic SBOM along with a gap analysis for PQC across wallets, nodes, and APIs, all packed together as our evidence package for SOC 2.
• Check out our ERC‑4337 smart account! It’s rocking a dual verification policy combining ECDSA and ML‑DSA/Falcon, and it’s all controlled by a feature flag.
• Our ZK prover service is pretty neat; it verifies PQ signatures and spits out STARK proofs. We’ve even integrated a Solidity verifier for an extra layer of security.
• We’re rolling out PQ‑TLS on RPC gateways and custodian links, with thorough testing done on Chrome/ML‑KEM and AWS ML‑KEM.
• Don’t miss our procurement artifacts: we’ve got a PQC Migration Plan, a TLS Cipher Policy, and a Proof‑of‑Concept report ready for review.

Success Metrics

• We're seeing an impressive 85-92% drop in the gas costs for per-operation verification compared to the traditional on-chain PQ verification. Specifically, we’re targeting around 0.5-0.8M gas per verification using STARK, whereas on-chain Dilithium clocks in at about 6.6M. (github.com)
• There's less than a 1% impact on p99 latency for user flows. Thanks to off-chain proving, the PQ-TLS only adds a tiny bit of overhead--just sub-ms per AWS KMS data--when we reuse connections. (aws.amazon.com)
• The SOC 2 evidence pack is all set to go, covering change management, key policies, TLS posture, and test results.

Rollout (Months 3-12): Scale and Harden

During this phase, it's all about ramping things up and making sure everything's solid. Here’s what to focus on:

1. Scaling the Infrastructure
   Make sure your systems can handle more users and increased demand. This might involve upgrading servers, optimizing databases, and ensuring everything runs smoothly.
2. Monitoring and Optimization
   Keep a close eye on performance. Use tools to track metrics and identify any bottlenecks. Regularly optimize processes to enhance speed and efficiency.
3. Adding New Features
   Gather feedback from users and choose the most requested features to add. Prioritize enhancements that will improve the user experience.
4. Security Enhancements
   Strengthen your security measures. Regular vulnerability assessments and updates can help protect user data and maintain trust.
5. Documentation and Training
   Create comprehensive documentation for your team and users. Consider hosting training sessions to ensure everyone is up to speed on new features and best practices.
6. Engagement and Community Building
   Foster a community around your product. Engage users through forums, social media, or events, and encourage them to share their experiences and suggestions.

By the end of this phase, you’ll want to have a robust, well-optimized system that's ready for even more growth!

• We're rolling out PQ smart accounts gradually; let's set up the “either-of” option to “PQ-only” by cohort.
• For L2s that support PQ primitives ahead of time, let’s make sure we’re ready for precompile-aware deployment and keep an eye on the Falcon/Dilithium precompiles (check out EIP-8052 and related discussions).
• Let's expand our STARK circuits to include session keys, policy proofs, and cross-chain attestations.
• We need to enhance our enterprise tools with HSM/KMS integrations for ML-DSA/Falcon keys and make sure we have solid operational runbooks and disaster recovery plans in place.
• Time to align with our vendors: we should update custodial SLAs, adjust pen-test scopes, and fine-tune our incident response strategies to reflect the PQC context.

-- Technical Specs We Use (for illustration) --

• AA Verification Policy
  • The validateUserOp function can take in either:
    • An ECDSA using secp256k1, OR
    • A STARK proof that confirms “ML‑DSA verified msgHash under PQ‑pubkey.”
• Prover/Verifier
  • Off-chain: We handle ML‑DSA/Falcon verification in Rust or C, ensuring our builds can be reproduced reliably.
  • On-chain: There’s a STARK verifier circuit that sticks to Keccak/SHA‑256 constraints, keeping us quantum-resilient.
  • Gas target: Expect around 500-770k per proof verification (this depends on the circuit). Check out more details here.
• Transport Security
  • Our TLS policy leans towards ML‑KEM768+X25519; we manage a fail-open setup with careful control. Plus, Cloud/CI/CD endpoints are rigorously tested against Chrome ML‑KEM codepoints and AWS ML‑KEM endpoints. You can read more about this here.

Frequently Asked Executive Questions

• Do we need to change our chain? Nope! With ERC‑4337, we can handle PQ signature validation right at the account level. You can even try it out on mainnet/L2 without needing any consensus forks. (ercs.ethereum.org)
• Are we locking into one algorithm? Not at all! We’re all about crypto‑agility here. We’ll kick things off with ML‑DSA (FIPS 204) or Falcon as soon as it gets the green light. Plus, we’ll keep using SLH‑DSA for firmware and code signing, and we’re leaving space for HQC at the transport/KEM layer. (nist.gov)
• What about our ZK roadmap? We're focusing on STARKs because they’re hash-based and quantum-resilient. We’re managing SNARK dependencies by setting up migration windows and bumping up hash sizes. (starkware.co)
• Will auditors accept this? Absolutely! Auditors want to see an inventory, a solid policy, and proof that we’re making progress on migration. We’re generating SOC 2‑ready artifacts and making sure we’re in line with CISA/NSA guidance. (cisa.gov)
