COMPLIANCE, IDENTITY AND REGULATION

Sanctions Compliance

The obligation to screen blockchain transactions against government sanctions lists (OFAC, EU, UN) and block transfers to or from designated addresses, individuals, or entities—a particular challenge in permissionless blockchain environments.

EXAMPLE

After the Tornado Cash sanctions designation, U.S. banks implementing stablecoin infrastructure had to demonstrate technical capability to reject transactions from sanctioned smart contract addresses.

On-Chain Analytics

The use of data analysis tools to track, monitor, and interpret blockchain transaction flows, wallet behaviors, and protocol usage patterns. Institutions use on-chain analytics for compliance, fraud detection, and market intelligence.

Example

Chainalysis provides banks with real-time on-chain analytics to flag transactions involving sanctioned addresses, high-risk jurisdictions, or mixing services before processing deposits.

Regulatory Reporting

The obligation to submit transaction data, positions, and risk exposures to regulators. On-chain activity can streamline reporting by making ledger data directly auditable, though it also raises new questions about jurisdiction and data access.

Example

An immutable on-chain trade record could replace post-trade reporting to DTCC, giving the SEC real-time visibility into institutional digital asset positions.

On-Chain Compliance

The embedding of regulatory requirements—KYC/AML checks, transfer restrictions, investor eligibility rules, and reporting obligations—directly into token logic or smart contracts, enabling automated enforcement at the point of transaction.

Example

Securitize embeds on-chain compliance into tokenized fund transfers so that accredited investor checks run automatically before any secondary market transaction settles.
