The Future Cryptography Conference returned to Tallinn on 20 May 2026, this year focusing on Zero Knowledge Proof (ZKP): how it is reshaping digital identity, and what the future holds.
Digital identity is now embedded in nearly everything: how we move money, access services, prove who we are. For years the main worry was whether credentials could be stolen. Less discussed is what identity providers learn simply by doing their job. Every time you present a credential, the data you share to prove one thing ends up proving many others.
Zero Knowledge Proofs reframe what verification can look like. Prove you're old enough without revealing your birthdate. Solvent without sharing your transactions. The talks in Tallinn traced how far into real infrastructure that idea has now reached, from EU identity wallets and e-governance to Web3 and AI.
In this talk, Peeter Laud, Senior Researcher at Cybernetica, takes on a familiar challenge in blockchain adoption: what if users could authenticate and post transactions without ever managing a private key or exposing their personal data? The approach is as practical as it is clever, designed to run entirely in the browser and make privacy-preserving blockchain authentication genuinely accessible to everyday users.
