Zero Knowledge Proof of Age Using Hash Chains

We demonstrate a zero-knowledge proof of age protocol that could be easily implemented on a proof of process network. In a recent post, we outlined a technique of proving that a hidden value »

Zero-Knowledge Proof of Balance: A Friendly ZKP Demo

Here at Stratumn Research we are currently applying various cryptographic primitives to allow participants finer control over their confidential information, even when it is shared in some way. Our general approach is to »

On the Instrumentalization of Trust

Sharing involves the risk of losing control. Today the cost of storage and transfer of the information is negligible. There's no more economic barrier to prevent the copying and storing of someone else's »

Identity as a Process - Part II

This is part of a series on Identity. Part I is here. While identity is modeled as a noun in the old paradigm, in the new paradigm it is modeled as an active »

Identity as a Process - Part I

We can begin to consider a new paradigm for identity by thinking in terms of chains of processes. If a process can be digitally modeled as a chain then each step of the »

Breaking out of Distributed Ledgers

When thinking about “revolution”, we can picture how a wheel turns. By starting with some momentum, we turn through the first 180 degrees as we accept the status quo. Then, turning through the »

The Three Mountains

First mountains are mountains, rivers are rivers. Then rivers are not rivers, mountains are not mountains. Then rivers are rivers and mountains and mountains again. But the third mountain is not the same »

From Security to Trust

Security is about protecting the data from attacks that are external to the accepted participants in a network. Honesty is about ensuring the integrity of information provided by the participants. Security and honesty »
