The language of pre-mempool compliance, and the milestones behind it.

In 2026, QuantChainAnalysis submitted formal comments to the Financial Action Task Force's public consultation on the draft Implementation Guidance for Recommendation 16, the global standard governing Travel Rule compliance for cross-border payments and virtual asset transfers. Recommendation 16 is the single most consequential rule for how originator and beneficiary information moves alongside a payment, and FATF's implementation guidance determines how strictly and how uniformly virtual asset service providers around the world will be expected to apply it. QCA's submission drew on its operational experience building and running QARS in production rather than on theoretical policy analysis, and included a dedicated proposal addressing how pre-broadcast risk assessment can serve as an implementation model for the Travel Rule in virtual asset environments. FATF confirmed the submission would be shared with the project team developing the final Guidance, alongside input from public and private sector experts across the industry.

QCA's paper on the QARS pre-broadcast risk scoring methodology was accepted for B2C 2026 (Sensors & Transducers / IFSA), held in Las Palmas de Gran Canaria in October 2026. The paper sets out the methodology behind pre-broadcast risk scoring and the corpus-based evaluation approach used to test it, written for an interdisciplinary sensors, transducers, and applied technology audience rather than a purely regulatory one. Founder and CEO Praveen Giri is presenting the paper in the Oral session via live Zoom, taking questions in real time alongside attendees at the venue rather than submitting a static recording.

A second, separately reviewed paper, titled "Pre-Mempool Blockchain Transaction Compliance: Regulatory Convergence of MiCA, FATF Recommendation 16, and the GENIUS Act toward a Pre-Broadcast Blocking Mandate," was accepted for ICICPE 2026 as Paper ID 26. The paper argues that three regulatory regimes, the EU's MiCA, FATF's Recommendation 16, and the US GENIUS Act, are converging on the same underlying requirement, a pre-broadcast blocking capability, independently of one another and largely without cross-reference.

The full QARS methodology, including the thirteen-dimension risk framework and its Born-rule interference model, is described in a complete manuscript currently under peer review at Financial Innovation, a Springer journal. This is a longer, more technically complete treatment than either conference paper, covering the corpus construction, the statistical testing framework, and both the production linear model and the experimental interference model side by side. QCA reports its status accurately as under review, consistent with a standing internal policy against fabricating or overstating results, and will update this entry if and when that status changes.

QCA's core pre-mempool enforcement architecture, including the Born-rule quantum amplitude interference mechanism, is the subject of a German patent application filed with the Deutsches Patent- und Markenamt (DPMA) in April 2026, comprising 17 claims across 6 technical components. The filing establishes an April 2026 priority date, and both the European Patent Office and USPTO international pathways remain open should QCA choose to pursue broader territorial coverage. A related utility model application covering a narrower subset of the same architecture is also in prosecution.

QuantChainAnalysis was named a finalist for Innovator of the Year at the 2026 Finovate Awards, recognising the pre-mempool enforcement approach behind QARS v1.0 among the industry's shortlisted innovations for the year. Finovate is one of the longer-running fintech industry events, and its awards shortlist is judged by industry practitioners rather than academic reviewers, giving this recognition a different character from the B2C and ICICPE conference acceptances or the FATF consultation.

QuantChainAnalysis is an official Category 1 member of Bundesblock (Blockchain Bundesverband e.V.), Germany's blockchain industry association. Bundesblock is registered in Germany's lobby register under Section 2(1) LobbyRG, registration number RR005475, and represents blockchain industry interests to German and EU policymakers, alongside a wider community of blockchain companies operating in Germany.

QuantChainAnalysis has been confirmed as förderfähig (funding-eligible) under INVEST, Zuschuss für Wagniskapital, a programme run by the Bundesamt für Wirtschaft und Ausfuhrkontrolle (BAFA, the Federal Office for Economic Affairs and Export Control) on behalf of the Bundesministerium für Wirtschaft und Klimaschutz (BMWK, the Federal Ministry for Economic Affairs and Climate Action). INVEST does not fund QCA directly. Instead, it pays a tax-free acquisition grant, currently 25 percent of the investment sum, to private investors (business angels) who put at least 10,000 euros into a company BAFA has recognised as young and innovative, with an additional exit grant available on gains from a later profitable sale. The förderfähig status is granted for a fixed validity period following BAFA's review of the company's eligibility.

Following the launch of Revolut's EURR stablecoin on Ethereum and Polygon, QARS performed a genuine, live pre-broadcast screening of a Polygon wallet transacting in EURR. Not a simulation: a real transaction, screened before broadcast, correctly triggering FATF Recommendation 16 and EU Transfer of Funds Regulation requirements the moment the transfer crossed the reporting threshold, with sanctions screening executed across five independent lists in the same pass. The analysis ran within days of the stablecoin's launch.

QCA evaluates QARS against a corpus of thirteen independently attributed real-world exploit addresses spanning nine separate incidents, including Bybit, Harmony, Ronin, KelpDAO, WazirX, HTX, Stake.com, Poloniex, and CoinEx, rather than synthetic or simulated data. Every address in the corpus is independently attributed to a documented, publicly reported incident, not generated or assumed. On this corpus, the production pipeline correctly escalated 11 of 13 malicious addresses to a required verification or block gate before broadcast, a result reported alongside its statistical significance against a bare weighted-sum baseline rather than presented in isolation.

FATF Recommendation 16 requires virtual asset service providers to collect and share originator and beneficiary information for transfers above a reporting threshold, mirroring the wire transfer rules long applied in traditional finance. In practice, this means a sending VASP must obtain and pass along the name, account or wallet identifier, and often address information of both parties before or alongside the transfer itself, so the receiving VASP can screen it. Implementation guidance for how this applies specifically to virtual assets, including exactly when and how that information must travel, is still being finalised by FATF, which is the subject of the consultation QCA responded to above.

Regulation (EU) 2023/1113 applies FATF Recommendation 16 to crypto-assets in the EU. Since 30 December 2024, crypto-asset service providers must send and check originator and beneficiary information with every crypto-asset transfer, with no minimum threshold, and must take additional steps for transfers of more than EUR 1,000 involving self-hosted wallets. It applies alongside MiCA, the EU licensing regime for crypto-asset service providers.

The US Treasury's Office of Foreign Assets Control maintains the Specially Designated Nationals and Blocked Persons List, identifying individuals, entities, and wallet addresses subject to US sanctions. A single hit against this list carries some of the most severe compliance consequences of any signal QCA screens for, since US sanctions exposure can trigger obligations well beyond the immediate transaction. QCA screens against OFAC alongside the UK FCDO, EU Consolidated, UN, and Swiss SECO sanctions lists on every analysis, rather than relying on any single jurisdiction's list in isolation.

One of QARS's thirteen risk dimensions, measuring a wallet's graph distance from known sanctioned or designated addresses across a multi-hop counterparty walk, rather than checking only for an exact address match against a sanctions list. A wallet that has never directly transacted with a sanctioned address can still sit one or two hops away in the transaction graph, which is exactly the kind of exposure a simple list-match check would miss entirely.

A structured compliance filing describing suspected money laundering or terrorist financing activity, typically submitted by a regulated entity to its national financial intelligence unit. QCA generates SAR and forensic report output designed to support downstream filing obligations, documenting the signals and rules behind each decision, so the underlying analysis can be followed by an investigator, auditor or supervisor, not just inform an internal compliance decision.

A running record of a wallet's transaction counterparties and each one's individual risk contribution, computed at the data layer and surfaced in QCA's compliance reports, so an investigator sees not just a wallet's score, but who it has actually been transacting with and why each of those relationships mattered to the final number. This turns a single composite risk score into an auditable trail rather than a black-box output.
