Token-based Access Control (TBAC) is a security feature designed to enhance the management of access rights within decentralized databases. By utilizing cryptographic tokens, this feature allows for fine-grained access control, ensuring that only authorized users can access specific data or perform certain actions. Each token is associated with a set of permissions, which can be dynamically assigned or revoked, providing flexibility and security in data management. This approach not only enhances security but also aligns with the principles of decentralization, where trust is distributed among participants rather than centralized in a single authority.
