Shared KYC/AML Ledger for Correspondent Banking Partners

Eliminate redundant checks for shared customers. Each partner verifies a customer once, and the immutable audit trail is accessible to all authorized participants. This directly reduces labor, third-party data fees, and processing time.

• Example: A global bank consortium reduced per-customer onboarding costs from ~$60 to under $15.
• ROI Driver: Faster time-to-revenue and reallocation of compliance staff to higher-value tasks.

A single source of truth for customer due diligence provides regulators with a transparent, tamper-proof record. This demonstrates robust compliance controls and can significantly reduce the risk of punitive fines for AML lapses.

• Real-World Parallel: The global banking industry paid over $10B in AML fines in a recent year. A shared ledger provides defensible proof of diligence.
• Benefit: Enhanced regulatory trust and a stronger case during audits, turning compliance from a cost center into a risk shield.

Speed and trust become competitive advantages. Enable seamless, secure customer portability between your services and partner ecosystems (e.g., banking to insurance, or between supply chain financiers).

• Mechanism: Pre-verified customers can be onboarded in minutes, not weeks, accelerating joint ventures and embedded finance models.
• Business Impact: Capture market share by being the easiest network to do business with, directly driving new customer acquisition and partnership fees.

Move from manual, periodic reviews to real-time risk management. Smart contracts can automatically flag changes in customer risk profiles (e.g., new PEP status, sanctions) and propagate alert notifications to all relevant network participants.

• Efficiency Gain: Reduces the operational lag and potential oversight inherent in siloed systems.
• Compliance Boost: Ensures all partners are acting on the latest information, maintaining network-wide integrity and meeting 'continuous monitoring' regulatory expectations.

Solve the data-sharing dilemma. The ledger stores only cryptographic proofs and attestations (hashes, zero-knowledge proofs), not raw PII. Partners verify claims without exposing underlying sensitive data.

• Key Feature: Customers can grant and revoke access to their verification data, aligning with GDPR/CCPA 'right to be forgotten' mandates.
• Strategic Benefit: Builds consumer trust and enables compliance in cross-border partnerships where data sovereignty laws differ.

The shared ledger becomes core infrastructure. Early adopters establish the standards and governance, creating high switching costs and network effects. The value of the network grows with each new participant.

• Long-Term ROI: Transition from competing on compliance overhead to competing on network access and innovation speed.
• Example: Similar to how SWIFT defined bank messaging, a dominant KYC ledger could define trusted digital identity for entire industry verticals.

The Pain Point: Each financial institution in a partnership repeats the same expensive KYC checks, costing $50-$100 per customer and creating a poor user experience.

The Blockchain Fix: A permissioned ledger creates a single, verifiable source of truth for customer identity and compliance status. Once one partner validates a customer, others can rely on that attestation with cryptographic proof, slashing onboarding time from weeks to minutes.

• Real Example: A consortium of Asian banks reduced cross-border corporate client onboarding from 45 days to near-instant, capturing new business worth millions.

The Pain Point: Manual compilation of transaction data for AML reporting is error-prone, slow, and exposes firms to regulatory fines.

The Blockchain Fix: Every KYC event and subsequent transaction flag is immutably recorded on the shared ledger. This creates an automated, tamper-proof audit trail that regulators can permission to view directly, turning compliance from a cost center into a streamlined process.

• Real Example: A European trade finance platform uses a shared ledger to automatically generate reports for multiple national regulators, cutting compliance team workload by over 60%.

The Pain Point: Sharing sensitive customer data between partners risks breaches and violates data sovereignty laws (like GDPR).

The Blockchain Fix: Zero-Knowledge Proofs (ZKPs) and selective disclosure protocols allow partners to prove a customer is verified without exposing the underlying personal data. You share the proof, not the data, maintaining privacy and compliance.

• Real Example: A pilot between insurers uses ZKPs to confirm a customer's eligibility across providers without sharing full medical history, enabling new bundled products.

The Pain Point: Expanding services through fintechs or distributors is hampered by slow, manual trust and compliance checks on each new entity.

The Blockchain Fix: A shared ledger acts as a decentralized reputation system. Partners' own KYC/KYB status and compliance history are transparently recorded, enabling faster, lower-risk ecosystem growth. New partners can be onboarded based on verifiable track records.

• Real Example: A global payments network uses a shared KYB ledger to onboard merchant acquirers 75% faster, accelerating market expansion into emerging regions.

Start with a focused pilot to prove ROI without a full-scale overhaul.

1. Phase 1: Consortium Formation: Partner with 2-3 trusted entities in your value chain.
2. Phase 2: Limited Pilot: Apply the shared ledger to a single, high-friction process (e.g., correspondent banking KYC).
3. Phase 3: Measure & Scale: Quantify cost savings and speed gains. Use this data to justify expanding to more partners and use cases.

Key Takeaway: The business case is built on shared cost reduction, not just technology. The ledger distributes the infrastructure cost while multiplying the benefit.
