The Proof is in the Protocol:
Philosophers often see identity as fluid—shaped by personal experience—while institutions treat it as fixed, anchored by documents or databases. Yet despite these contrasting views, identity has always been crucial because it determines access. Whether we’re talking about property, opportunities, or societal belonging, identity is the key that grants or denies entry.
What is a zero-knowledge proof?
One of the core principles of Web3, transparency, can also be one of its greatest drawbacks. Nobody wants all of their online activity, from financial transactions to personal identity data, to be publicly available for anyone to view. In order for blockchains to scale and become more accessible, privacy has to be a priority.
