Short version: TVS (Total Value Shielded) is the key metric that shows if your privacy setup is doing its job in a real-world scenario. When you can measure, boost, and defend your TVS, you can roll out private payments and procurement processes that sail through audits, pass OFAC/KYT checks, and meet ISO 20022 deadlines--all without throwing your engineering team off course.

The headache your team is living with

Your CFO is pushing for on-chain vendor payouts in USDC next quarter. At the same time, your CISO is insisting on privacy by design (thanks to GDPR Art. 25) and wants those logs to be audit-ready. Compliance is in the mix too, asking for “OFAC-clean” flows and know-your-transaction (KYT) outputs. Meanwhile, the engineering team is juggling between ISO 20022 cutovers and wallet plumbing, and let’s not forget, you still lack a solid metric that shows your privacy pipeline is delivering anything more than just demo environments. (gdpr-info.eu)

If you can't measure it, you can't manage it. Without a solid, production-grade privacy KPI, you're basically in the dark. This means you can't predict liquidity in shielded addresses, you can't figure out the right size for anonymity sets during procurement runs, and you can't demonstrate ROI to the board.

---

What’s actually at risk

• Missed industry deadlines and rework:
  • So, the SWIFT coexistence deadline is set for November 22, 2025. If your privacy flows aren't aligned with the ISO 20022 case management (camt.110/111) and recalls (camt.056/029), you’re going to find yourself scrambling to create one-offs under audit pressure. Plus, don’t forget that this contingency translation is going to add fees and some unwanted friction. Check this out for more details: (swift.com).
  • Fedwire’s ISO 20022 go-live on July 14, 2025, also means you’ll be forced to remodel your messages; any private payment wrapper that can’t handle rich remittance data? That’s a recipe for reconciliation headaches within your ERP systems. More info here: (frbservices.org).
• Censorship and “stall risk” on L1/L2:
  • Ethereum's core developers have made FOCIL (EIP-7805) a top priority to help counter transaction filtering in Hegotá. Until those guarantees are in place, you might find your privacy transactions getting sidelined by builders and relays. In other words, your private payouts could get stuck at the most inconvenient times. Dive deeper here: (eips.ethereum.org).
• Policy whiplash if you choose the wrong primitive:
  • The 2025 Tornado Cash delisting by OFAC really shook up the compliance landscape. The takeaway isn’t just to “use mixers” -- it's about building privacy solutions that incorporate selective disclosure and KYT-compatible proofs (like Privacy Pools’ association sets), so any sudden policy changes don’t wreck your setup. Learn more about it here: (home.treasury.gov).
• Liquidity and pricing blind spots:
  • Take Zcash, for example -- it shows how quickly “shielding” can eat into the available tradable float. Their shielded supply jumped to around 30.4% on February 9, 2026. That’s great for privacy but something you definitely need to keep in mind when planning for OTC and treasury operations, especially regarding slippage and availability. If you’re not keeping an eye on TVS, you might end up mispricing your execution windows. More on this here: (zkp.baby).

7Block Labs’ TVS‑first methodology

We’re all about making privacy easy to measure, comply with, and actually implement. Our strategy combines top-notch protocol-level ZK engineering with real-world procurement and treasury results. Let’s kick things off:

1) Define TVS precisely for your stack

TVS (Total Value Shielded) represents the estimated value of assets that are currently stored in addresses or notes which align with your privacy policy and disclosure standards.

• UTXO/privacy L1s (like Zcash): To figure out the Total Validated Supply (TVS), add up the balances from Sprout, Sapling, and Orchard, then subtract any known self-change. It’s also a good idea to break things down by pool to accurately reflect the different proving systems. You can keep an eye on the “Shielded Percentage” by calculating TVS / Circulating Supply. Check it out here.
• EVM privacy apps (like Railgun and Privacy Pools): For these, the TVS is determined by the protocol’s “private balance” across all the supported assets that allow for selective disclosure (think proofs of association or innocence). It's smart to maintain a separate “Compliant TVS” too, which leaves out any quarantined or flagged association sets. More on this can be found here.
• Enterprise L1s adding native ZK (like Stellar Protocol 25 “X‑Ray”): Here, the TVS consists of the assets locked behind ZK-verified processes, which come along with a view-key escrow policy (using BN254/Poseidon for verification). For more details, visit this link.

Operational Derivatives We Instrument on Day One

• Shielded Coverage Ratio (SCR): This is calculated by taking the TVS and dividing it by the Total On-chain Float, all based on the specific asset you’re dealing with.
• Effective Anonymity Set (EAS): Here, we look at the unique notes and commitments within your policy-approved association sets over a rolling window--think about it like the last 30 days (T-30).
• Shielded Turnover (STO): This one's pretty straightforward. We take the private inflow and outflow over the last 30 days and divide that by the TVS. It helps us spot “stale” pools that might be in need of some liquidity seeding or a little fee adjustment.
• Compliant Utilization (CU): This metric checks out the share of private payments that come with KYT-clean association proofs and signed attestations.

These are the “money metrics” that your CFO and CISO take a look at, right there with the cash forecasts.

2) Instrumentation: from node to ERP

We set up a streamlined data plane that's easy to audit:

• Indexers and Provers
  • ZEC: We're pulling data from zkp.baby using our verifier to keep those snapshots fresh--no more stale info! Plus, we're tying everything to block heights for sorting out disputes, whether it’s Orchard or Sapling.
  • EVM: We’ve set up event-sourced listeners for Railgun’s “0zk” notes and those Merkle sets from Privacy Pools. On top of that, we’re building a policy engine to manage inclusion and exclusion rules for association sets--compliance has got this covered! Check out more on Medium.
  • Stellar Soroban: We're implementing on-chain BN254/Poseidon verification receipts for zero-knowledge proofs, all linked back to our internal vendor IDs. Got more details at Stellar.
• KYT + Selective Disclosure
  • We're all about enforcing proofs-of-innocence and association for private withdrawals. We also keep an archive of “proof receipts” with nonces and circuit hashes for audits--don't worry, no personal info is on-chain! For more info, check this news release.
• ERP Connectors
  • We’ve got ISO 20022 payload mappers for pacs.008/009 and camt.056/029 (just for recalls), along with case management (camt.110/111). This way, even private transfers can be reconciled and recalled with a solid audit trail. For more details, visit Swift.
• Key Management
  • We're using HSM-backed view keys under dual control, setting up rotation SLAs, and having selective reveal workflows that align with subpoena and FPCA processes.

Where we come in:

• Looking for engineers who have done this before? Our custom blockchain development services and web3 development services handle everything from indexers to circuits and policy engines.
• Need integrations that keep your back office running smoothly? Our blockchain integration crew expertly maps out ISO 20022 and ERP schemas from start to finish.

3) Choose the right primitives for 2026

• Ethereum (today/tomorrow):
  • EIP-7701 (the native AA upgrade) is rolling out, which means we can now unlock “sponsor gas privately” flows. This is super important for paying vendors without revealing who's footing the bill from shielded balances. So, it’s time to think about AA-native wallets and how to set up your paymaster policies. Check it out here: (eips.ethereum.org).
  • With FOCIL/EIP-7805, we’re shifting censorship resistance into fork choice. Just a heads up--until this goes live, you should plan for “stall risk” on private transactions and make sure to pre-fund time buffers in your disbursement runs. More details available here: (eips.ethereum.org).
  • Privacy Pools are here for keeping things compliant, plus they provide attestation receipts. We’ve teamed up with 0xbow to integrate their ASP outputs, allowing Compliance to tweak the rulebooks as needed. Dive deeper into it here: (globenewswire.com).
• Zcash:
  • Zcash is setting a solid privacy standard--at times, the shielded percentage has climbed above 30%! This is a great indication of strong anonymity sets for those sensitive treasury moves. Be sure to create playbooks for Orchard-only flows to standardize your proof systems. More info can be found here: (finance.yahoo.com).
• Stellar:
  • Protocol 25, also known as “X-Ray,” is introducing BN254 and Poseidon. If you're in the regulated payment corridor that talks ISO 20022, this is going to be a smart solution for private remittances with first-party ZK verification. You can read all about it here: (stellar.org).

Where We Plug In:

• Looking into a privacy L2 or a compliant mixer alternative? Our teams specializing in cross‑chain solutions development, DeFi development services, and smart contract development are here to help. We carefully measure latency, proof costs, and CU% across various options to find what suits you best.

4) Make TVS drive procurement and treasury ROI

Tie TVS Directly to Business Levers:

When you're looking to connect TVS (Total Value of Services) with key business levers, it's all about understanding how these metrics influence your overall performance. Here’s how you can do that:

1. Identify Key Business Objectives: Start by figuring out your main goals. Are you trying to boost revenue, enhance customer satisfaction, or drive efficiency? Knowing your targets will help you tailor your TVS measurements.
2. Map TVS to Performance Indicators: Once you know your objectives, link your TVS metrics directly to your performance indicators. For example, if you want to improve customer satisfaction, you could look at TVS as it relates to service delivery times or response rates.
3. Use Data Analytics: Leverage data analytics to get insights on how TVS impacts your business levers. This could involve diving into customer feedback, transaction data, or operational metrics to see what's working and what's not.
4. Regularly Review and Adjust: Make it a habit to review how TVS is performing in relation to your business levers. If something doesn’t seem to align, don’t hesitate to tweak your approach. It’s all about being flexible and responsive.
5. Engage Stakeholders: Keep everyone in the loop! Share your findings with relevant teams and stakeholders. Their insights can be invaluable, and it helps to cultivate a collaborative approach to driving value.

By closely tying TVS to your business levers, you can ensure that your strategies are aligning with your overall mission and driving real, measurable improvements.

• Procurement
  • Objective: Keep those sensitive vendor terms under wraps while making sure we can still recall them and comply with SOX 404 requirements.
  • Mechanism: Make payments using Privacy Pools or Railgun from shielded balances, and attach those association-set attestations. We’ll also need to log the ISO 20022 remittance data off-chain and pre-stage camt.056 recall payloads to handle exceptions smoothly. (finance.yahoo.com)
  • KPI: Aim for a CU% of 98% or higher across payouts, and keep the median disbursement time below the p95 target--even when the mempool gets a bit overloaded (FOCIL isn’t active just yet). (blog.ethereum.org)
• Treasury
  • Objective: Reduce any information leakage and slippage during big rebalancing moves.
  • Mechanism: Plan for some “dark rebalances” in shielded pools where the anonymity sets (EAS) are above the threshold; then we’ll back out through compliant withdrawal windows.
  • KPI: Keep an eye on the SCR trend and STO bands to know when to bring in LP/market-maker support before launching a campaign (like the ZEC case, which shows that float tends to shrink when shielding activity spikes). (zkp.baby)

Where we come in:

• We provide TVS dashboards, EAS/STO/CU monitoring, and playbooks via our asset management platform development.

5) A 90‑day blueprint (no archaeology, just shipping)

• Weeks 1‑2: Let’s kick things off by working on our privacy posture and policy modeling, which includes setting up those association sets and reveal triggers. We’ll also map out the ISO 20022 touchpoints and figure out our KPIs, like TVS, EAS, CU, and STO.
• Weeks 3‑6: Next up, we’ll get our indexers up and running, along with the proof receipt store and KYT adapters. We’ll need to connect the paymasters/AA for private gas wherever it makes sense, and start implementing those HSM view-key operations.
• Weeks 7‑10: During this phase, we'll pilot vendor payouts using test assets. We should also conduct some failover drills--think recall, stall, and censorship--to make sure everything's solid. Plus, let’s fine-tune our mempool and fee policies while we’re at it.
• Weeks 11‑12: To wrap things up, we’ll carry out a thorough security review and bring in the red team. Once that’s done, we’ll sign off on the control narratives and get ready to migrate our first production cohort.

Looking to raise some funds to keep your project going while you build? We’ve got your back with top-notch investor-ready materials and thorough due diligence through our fundraising practice, all rooted in TVS-based traction.

Prove -- Market signals and GTM metrics you can copy

Evidence that TVS is the Right North Star for Privacy Adoption:

When it comes to privacy, TVS truly shines as a guiding light. Here’s a closer look at why it’s the go-to framework for adopting privacy practices:

• Proven Success: Numerous companies that have embraced TVS have seen significant improvements in their privacy protocols. This framework isn’t just theoretical; it’s backed by real-world results.
• Flexible Approach: TVS isn’t a one-size-fits-all solution. It allows organizations to tailor their privacy strategies to fit their unique needs and challenges.
• Strong Community Support: There’s a growing community around TVS that shares resources and best practices. This network can be invaluable for organizations looking to navigate their privacy journey.
• Regulatory Alignment: TVS aligns well with various regulations, making it easier for companies to stay compliant without feeling overwhelmed.
• Focus on User Trust: At its core, TVS places a strong emphasis on building user trust. A focus on transparency and accountability means better relationships with consumers.

By following the TVS framework, organizations can effectively enhance their privacy practices and navigate the complexities of today’s data landscape.

• Zcash’s Shielded Value as a Network-Level TVS Indicator:
  • By November 2025, the shielded percentage hit around 23%, and even peaked at over 30%. As of February 9, 2026, the dashboard is showing a Shielded Percentage of about 30.4% and a Total Shielded Value of approximately 5.03M ZEC. This really points to a solid shift towards private balances among users--it's not just a marketing gimmick, there's real privacy utility happening here. (theblock.co)
• Railgun’s TVS/Usage Momentum:
  • So, Railgun has seen its “value held in 0zk addresses” jump from around $14M in January 2024 to over $90M by December 2024. Plus, the all-time shielded volume has now gone past $4B, thanks to the Ethereum Foundation's Kohaku wallet integration. That’s a big step towards making wallet-level privacy user-friendly. A takeaway here: it’s all about building in places where wallets can switch privacy on by default. (medium.com)
• Compliant Privacy Productization:
  • In 2025, Privacy Pools made their debut on the Ethereum mainnet and even added stablecoin support. They also rolled out an “Association Set Provider” (0xbow) model for KYT-friendly proofs--exactly what businesses need to keep things private without mingling with tainted funds. Early usage might seem small (over $6M, with 1,500 users), but it’s definitely heading in the right direction--let's track it as Compliant TVS. (rootdata.com)
• Protocol-Level Privacy Plumbing for Payments:
  • Stellar's Protocol 25, dubbed “X-Ray,” introduced BN254/Poseidon primitives on-chain in January 2026 (testnet on January 7; mainnet vote on January 22). This allows for in-contract verification of ZK proofs, which makes it easier to integrate selective disclosure with ISO 20022 flows. A key lesson here: when your Layer 1 can handle ZK natively, your TVS has the potential to grow without sacrificing user experience. (stellar.org)
• Regulatory Posture is Evolving Toward Selective Disclosure:
  • After some legal back-and-forth, the OFAC delisted Tornado Cash in March 2025. No matter how you feel about it, the takeaway is to design systems that support attestable innocence instead of relying on opaque mixing--this way, when policies shift, your TVS won’t take a nosedive. (ofac.treasury.gov)

What to Add to Your GTM Dashboard Next Quarter:

• TVS Growth Rate: Check out the growth rate (after accounting for quarantined funds) by asset and corridor.
• EAS Threshold Breaches: Keep an eye on how many threshold breaches we’ve got compared to our planned payout batches.
• CU% Breakdown: Break down the CU% by vendor tier and geography--this will help demonstrate how we’re balancing “privacy with compliance.”
• ISO 20022 Exception Rate: Look into the exception rate on private payments, including things like recalls and case management.
• Stall Risk Tracking: Track stall risks in relation to mempool stress until FOCIL comes in, making sure to monitor the p95 time-to-finality SLOs. Check out more details here.

1) Private Vendor Payouts with Recallability (USDC on Ethereum)

• Flow: Start by funding a shielded balance. Next, batch up those supplier invoices. For every payout, you'll generate a Privacy Pools proof along with an association-set attestation. To keep things discreet, submit this through an AA paymaster, so you don't end up doxxing your fee payer. Don’t forget to archive the proof receipt and ISO 20022 remittance off-chain. It's also good to keep camt.056 templates on hand for any exception recalls. Lastly, keep an eye on your CU% and p95 finality. (eips.ethereum.org)
• Why it works: This setup gives you that sweet spot of “privacy with an audit button.” You can enjoy dual control over view keys, have attestation receipts for compliance, and maintain recall pipelines that line up with ISO timelines.

2) Dark Treasury Rebalance (ZEC)

• Flow: When EAS goes above a certain threshold and STO stays within the band, start shifting tranches into Orchard. Make sure to exit using proof-of-innocence windows that match up with when the desk is free. Keep an eye on the TVS drift so you don’t end up stuck in a liquidity crunch. (zkp.baby)
• Why it works: This strategy lets you take advantage of deep anonymity sets while making sure that liquidity risk is clear for OTC operations.

3) Regulated Corridor Pilot (Stellar)

• Flow: We're utilizing Soroban contracts combined with BN254/Poseidon to check ZK proofs of eligibility. This is done while keeping amounts and beneficiaries under wraps, only visible to those who really need to know. Plus, we're embedding ISO 20022 IDs to ensure smooth, straight-through reconciliation. Check it out on stellar.org.
• Why it works: The magic happens with the combination of native ZK and ISO 20022 alignment. This approach ticks all the boxes for treasury, compliance, and engineering in one go!

Where we jump in:

• We help create and launch everything mentioned above with our awesome cross‑chain solutions development, blockchain bridge development, and dApp development teams.

Emerging best practices (brief, in‑depth notes)

• Go for “attestable privacy” instead of mixers:
  • Using Association sets (Privacy Pools) along with KYT gives you some solid ground to stand on with auditors, especially as regulations keep changing. Make sure to treat attestation receipt storage as a key piece in your evidence toolkit. (rootdata.com)
• Build for censorship resistance:
  • Until FOCIL is in the game, keep a budget handy for private transaction inclusion and keep an eye on mempool vendors. As FOCIL/AA get more stable, start planning those migrations to AA-native wallets and enforce your paymaster policies. (eips.ethereum.org)
• Handle view keys like they’re top-secret info:
  • Use HSM custody, set up dual controls, rotate periodically, and stick to “n-of-m” disclosure processes that are tied to legal triggers. Only log proof receipts, and skip the plaintexts.
• Connect privacy to ISO 20022 right from the start:
  • If your private payment can’t whip up camt.110/111 case artifacts or camt.056/029 recalls, you’re likely to struggle with those operational readiness reviews. (swift.com)
• Share TVS updates with your execs every month:
  • Make sure TVS, EAS, STO, and CU% are right there with cash forecasts and accounts payable aging. When TVS goes up and CU% stays above 98%, you know your privacy go-to-market strategy is on point.
