Workshop Zama - How to build apps onchain with privacy

​Privacy is becoming a core part of onchain infrastructure.

​In this hands-on session, Valerio Leo, founder of Ray Cash, will explore how developers can use Zama to build privacy-preserving tools onchain, unlocking new applications beyond fully public smart contracts.

​Zama is an open-source cryptography company building Fully Homomorphic Encryption, or FHE, solutions for blockchain and AI. In simple terms, FHE allows computations to be performed on encrypted data without decrypting it first, making it possible to build applications that remain private even while they are being processed.

​We’ll explore how this new privacy infrastructure can enable better financial tools, more secure user experiences, and new categories of crypto applications.

​Bring your laptop. This is a practical workshop for builders who want to experiment, learn by doing, and better understand what privacy-preserving onchain applications can look like in practice. Zama’s developer stack is specifically aimed at helping builders create confidential smart contracts and dApps onchain.
