Time-locked Recovery Factors for Secret Sharing

Duration: 00:21:19

Speaker: Leonard Tan

Type: Talk

Expertise: Intermediate

Event: Devcon

Date: Oct 2022

Verifiable delay encryption allows us to construct time-locked secret shares which reveal themselves after some time. Paired with share refreshing, this allows users to automatically recover their account after a set amount of time even if they have lost secret shares, without compromising key security. Setup requires no user input which allows for a streamlined UX, and we show a demo of this functionality by generating and recovering a private key using this technique.
