Introducing Access Control Trie (ACT) in Swarm
🌐 Swarm’s new Access Control Trie (ACT) has been launched, bringing a powerful solution for managing access control in decentralized storage.
🔑 What is ACT?
ACT allows publishers to encrypt access keys for specific users, granting or revoking access to decentralized data at the block level. This ensures that only authorized users can view or access content.
💡 What makes ACT unique?
ACT even prevents unauthorized users from discovering encrypted data. This adds an extra layer of privacy protection by preventing anyone without access to detect the content.
📥 How does it work?
ACT uses session keys based on the grantee’s Swarm node wallet public key. These keys are used to derive lookup keys and decryption keys, allowing authorized users to securely retrieve and decrypt content.
🔒 Manage Access
Publishers can dynamically add or remove access rights for any user by modifying the ACT lookup table. This flexibility ensures that content access rights can be updated or revoked without compromising security.
⚙️ ACT Use Cases
ACT opens up new possibilities for content monetization, subscription services, and secure data sharing. From streaming platforms to private social networks, the potential is huge.
🔐 Fully Encrypted
Every part of the ACT process is encrypted — from the list of authorizers to the content access keys. This ensures that even if access is revoked, previously accessible data remains secure.
💼 Real World Applications
With Swarm’s decentralized, censorship-resistant infrastructure, ACT can help create privacy-centric platforms, such as subscription services, or store sensitive data with full control over access.
