What is the difference between Semaphore and Bandada?
Semaphore is a zero-knowledge protocol that allows users to prove their membership in a group and send messages, such as votes or feedback, without revealing their identity. It also provides a simple mechanism to prevent double-signaling. Semaphore works both off-chain and on EVM-compatible chains.
Bandada is an infrastructure for managing privacy-preserving groups. It also provides anti-sybil mechanisms by using credential groups, ensuring that only users meeting specific criteria can join a group.
Semaphore lacks an off-chain infrastructure for managing groups or storing group members, but Bandada fills this gap by simplifying the management of off-chain Semaphore groups. Though Semaphore and Bandada groups are different, they are fully compatible and work well together.
Joining a Semaphore group often requires an anti-sybil mechanism. Bandada integrates this functionality through its credentials package and invite codes functionality.
Bandada is well-suited for managing large groups, as it enables server-side creation of Merkle proofs, an approach that is especially useful when the group size is too large for client-side processing.
While Bandada does not have integrated zero-knowledge (zk) capabilities, it can be paired with Semaphore to add zk functionality to an application.
Semaphore provides a robust on-chain infrastructure for groups, which Bandada leverages for its own on-chain group management.
In summary, Semaphore and Bandada serve different purposes and offer distinct functionalities, but they are fully compatible and work effectively together.
