## Protocol-Level Address Blocking

Protocol-level Address Blocking is the direct implementation of restrictions within the smart contract code of a decentralized protocol to prevent specific addresses from interacting with it. This is the most effective form of blocking, as it is enforced by the blockchain itself and cannot be bypassed by changing the front-end interface.

While this provides a high level of security and compliance, it also centralizes control within the protocol's governance or administrative functions. This approach is often debated due to its impact on the core principles of decentralization and permissionless access.

However, it is increasingly used by protocols that require strict compliance to operate in regulated markets. It is a powerful tool that carries significant implications for the governance of the protocol.
