Diamond iO: New Cryptanalysis and Efficiency Improvements—Toward Ethereum Beyond Finance
Duration: NaN:NaN:NaN
Speaker: Sora Suegami
Type: Talk
Expertise: Some familiarity with the topic
Event: Devcon
Date: Nov 2026
Diamond iO is an implementable lattice-based iO we introduced. We will first present **attacks on its non-standard assumptions, particularly all-product LWE**. We will then present recent progress toward practical iO, including concrete efficiency improvements and **end-to-end performance estimates**. Finally, we will show how practical iO could turn Ethereum into infrastructure for **trustless confidential coordination**: parties with conflicting interests could entrust secrets to smart contracts that enable them to coordinate without revealing those secrets. This could make Ethereum compelling even to people uninterested in tokens or finance.
