Hands-on applications of zero-knowledge signalling

Duration: 00:54:50

Speaker: Wei Jie Koh

Type: Breakout

Expertise: beginner

Event: Devcon

Date: Jun 2026

Semaphore is a generalised zero-knowledge signalling system which can be deployed to fulfil various privacy use cases, such as a mixer and anonymous whistleblowing. This hands-on workshop will guide participants through a high-level explanation of how Semaphore and zero-knowledge proofs work, and guide them through an anonymous chat app integrated with POAP tokens which can generate and verify said proofs. No programming or zk-SNARK knowledge is needed.
