Compliance

Privacy is not the only requirement for enterprise-grade blockchain solutions, compliance is equally critical.
On Avalanche, whether you deploy to C-Chain Mainnet, Fuji (Testnet), or a custom L1, tokens must often meet regulatory obligations to operate legally in certain jurisdictions or industries.

Why Compliance Matters

In finance, healthcare, gaming, and government, compliance is not optional, it is enforced through regulations like:

• KYC/AML (Know Your Customer / Anti-Money Laundering): Identifying and verifying participants to prevent illegal activity.
• Jurisdictional restrictions: Blocking access from certain regions due to sanctions or laws.
• Data protection laws: GDPR (EU), HIPAA (US), and other frameworks require handling sensitive data in specific ways.

Challenges with Current Token Standards

Standard ERC-20, ERC-721, and ERC-1155 implementations on Avalanche offer no built-in compliance tools:

• No whitelisting or blacklisting capabilities at the protocol level.
• No selective disclosure: you cannot show transaction details only to authorized parties while hiding them from the public.
• No transaction-level restrictions to enforce rules automatically.

As a result, compliance must be built as a custom layer, which:

• Increases development and auditing costs.
• Introduces potential security risks if not implemented correctly.
• Creates inconsistency between projects, making interoperability harder.

The Compliance–Privacy Balance

True privacy on Avalanche must still allow authorized oversight:

• Auditor access: Regulators, tax authorities, or compliance officers should be able to review specific transactions without making them public.
• Selective decryption: Only authorized entities can view transaction amounts and counterparties.
• Revocable permissions: The ability to update who has access without redeploying the entire token contract.

Example in the Avalanche Ecosystem

Imagine an L1 created for a private lending network:

• Loans are issued in a privacy-enabled token to protect borrower data.
• Regulators need to verify the amounts, interest rates, and repayment schedules.
• Without compliance features, the project must either make all data public (losing privacy) or create a parallel off-chain audit system (increasing complexity).

In the next section, we will explore Necessities Solved with Privacy, real-world scenarios where privacy is not just a “nice to have,” but a critical requirement for operations, security, and compliance.
