Beacon Network Collective Defense Model
Stop illicit crypto flows with a coordinated industry-wide real-time blocking network.
The Beacon Network model creates a collective intelligence and enforcement layer across the crypto ecosystem by uniting major exchanges, fintech platforms, DeFi protocols, and law enforcement into a single real-time blocking network. When law enforcement agencies identify illicit wallet addresses moving funds, they flag them instantly; that flag triggers a beacon alert reaching every member platform simultaneously, requiring them to block the transaction and cooperate with seizure efforts. The model scales with membership — covering 85%+ of centralized crypto volume makes it nearly impossible for sanctioned actors to offramp through compliant venues. As bad actors route to non-member platforms, the network actively recruits those platforms, progressively eliminating escape routes. The framework achieves enforcement without compromising individual user privacy, since DeFi members block transactions without exposing user data.
- Network coverage is the primary defense — partial perimeters always fail at the edges.
- Response speed must match or exceed criminal movement speed.
- Technology-driven enforcement can preserve legitimate user privacy while blocking illicit flows.
- Follow the money: when bad actors evade, identify and onboard their next venue.
- Law enforcement and industry must operate as a unified response team, not adversaries.
- A network is only as strong as its weakest, least-compliant member.
- Recruit anchor exchange partnersApproach the highest-volume centralized exchanges first. Their participation creates the critical mass and credibility needed to make the network a genuine deterrent rather than a symbolic gesture.Pro tipStart with two or three marquee names — once Coinbase and Binance are in, mid-tier exchanges follow quickly to avoid competitive disadvantage.
- Expand to fintech platforms and DeFi protocolsAdd payment processors, neobanks, and DeFi smart contract platforms that can block flagged transactions at the protocol level, extending coverage far beyond centralized venues.Pro tipFor DeFi, emphasize that membership requires only blocking illicit addresses — no user data sharing — to overcome privacy objections from privacy-focused teams.
- Onboard law enforcement agencies as real-time flaggersPartner with national and international law enforcement agencies who will actively flag illicit wallet addresses the moment funds begin moving, providing the live intelligence the alert system depends on.WarningEnsure clear legal frameworks exist in each jurisdiction for sharing and acting on flagged address data before formally onboarding agencies.
- Build a real-time beacon alert distribution systemCreate an alert mechanism that instantly pushes flagged address notifications to all member platforms simultaneously, minimizing the window in which illicit funds can move between compliant venues.Pro tipTreat alert latency as a primary engineering KPI — every second of delay is a second during which funds can hop to another platform.
- Establish binding blocking and seizure obligationsMake it a formal condition of membership that when a beacon alert is received, platforms must block the flagged transaction and cooperate with any subsequent law enforcement seizure request.WarningWithout binding obligations, the network degrades into a voluntary information-sharing list that sophisticated actors exploit by routing to non-blocking members.
- Track evasion routes and onboard next-hop platformsMonitor where blocked actors attempt to move their funds after being blocked, and immediately begin recruiting those non-member platforms into the network to close the gap.Pro tipTreat every successful block as a data point that reveals the next weak link in the perimeter — use it as the opening for a membership conversation.
- Continuously audit and strengthen weak-link membersRegularly review member compliance with blocking obligations and identify platforms whose technical or legal constraints prevent them from acting on alerts, prioritizing remediation or replacement.WarningNon-compliant members don't just fail to help — they actively signal to bad actors that a safe passage route exists within the network.
After the Bybit hack, North Korea's Lazarus Group laundered funds faster than any single exchange's compliance team could respond. TRM Labs coordinated with Coinbase, Binance, Kraken, OKX, and 70+ global law enforcement agencies through the Beacon Network, pushing simultaneous block alerts across all members. The coordinated response matched the attackers' speed for the first time, dramatically slowing the laundering operation compared to prior incidents where no such coalition existed.
DeFi protocols joined Beacon despite concerns about centralization. The key enabling insight was that membership required only blocking flagged addresses at the smart contract level — no user data was shared with law enforcement or other members. The DeFi Education Fund actively briefed members of Congress alongside TRM Labs, demonstrating that this approach delivers stronger AML outcomes than traditional financial regulation without compromising the permissionless architecture DeFi communities value.
TRM Labs identified two UK-registered exchanges — Zed X and ZX Ion — processing nearly 80% of their transaction volume for Iran's IRGC. This network-level blockchain visibility fed directly into a US Treasury sanctions action that shuttered both exchanges. The case illustrated how systematic on-chain monitoring converts illicit crypto infrastructure detection into formal enforcement outcomes, validating the intelligence-to-action pipeline the Beacon model is designed to create.
Developed by TRM Labs after the Bybit hack, when North Korea's Lazarus Group was laundering funds faster than any individual exchange's compliance team could respond. Ari Redbord reached out to Coinbase and Binance to form the initial coalition, eventually growing to cover 85%+ of centralized crypto and 70+ global law enforcement agencies. Extracted from Bankless.
