There has been a lot of recent progress and interest in iO (Indistinguishability Obfuscation). This session will cover topics from the basics to theory and attempts at practical implementations—plus ways of breaking these attempts.

Breakout 2

Indistinguishability Obfuscation (iO)

Privacy is an unsolved challenge for blockchains and decentralized systems. ZK cryptography gets us there partially, but not all the way. ZK enables “single-player private state,” and certain other kinds of privacy are impossible to realize with ZKPs alone. Panelists, the cryptography library devs, infrastructure builders, and application devs who have recently started to explore programmable encryption will discuss MP-FHE as one such tool for achieving more general privacy capabilities.

Stage 6

Multi-Party FHE for Multi-Player Privacy

The talk introduces "phantom-zone", a framework to write scalable consumer facing MPC apps using multi-party FHE. Starting with what's multi-party FHE, talk gives a demo of non-trivial MPC app. Followed by introduction to programming model of MPC apps using multi-party FHE inside phantom-zone. Then the talk dives deep into primitives to realise multi-party FHE and ends with advanced FHE gadgets that further enhance multi-party FHE.
