Usher Labs' Verity Documentation

The home for developers and cryptographic experts exploring secure data integration with blockchains.

Welcome

Verity powers innovative applications through partnerships with leading networks and platforms.

Use Cases

Bringing sensitive or gated data on-chain demands robust security guarantees.

Getting Started

This topic covers operating the Verity Network Nodes via the CLI, and additional tools for verifying TLS proofs.

Network Nodes & CLI

The Verifier is a specialised Internet Computer (IC) Smart Contract (Canister) designed to verify TLS session proofs and full TLS proofs. It provides both asynchronous and direct verification methods, with the latter including tECDSA signatures for cross-chain or off-chain verification.

Introduction

To grasp the scope of Verity, it's important to understand each of stage of a provable data flow.

Proof of Data Flow

Verity is a network of nodes, that collectively collobrate over a protocol to verify data authenticity, integrity, and transformation.

Architecture

Verity's protocol is a sequence of specific steps between the network of nodes, resulting in proof of data flows.

Protocol

Verity employs a variety of cryptographic primitives to deliver on the core value proposition - verifiable data pipelines.

Cryptography

Data processing is an imperative for any data pipeline. Verity ensures the entire pipeline and lineage can be verified to authenticate data on destination chains.

Verifiable Data Processing Environment (VDPE)

Verity offers the framework and platform for creating pipelines, and guides developers to implement using standards. However, developers retain full control over their own implementation.

Implementations

This page aims to provide examples of TLS proofs generated by Verity to help developers understand the format and structure of the proofs.

Example TLS Proofs

Forwards any HTTP request to a target URL and generates TLS proofs

Proxy

Technically, any HTTP method can be used, but the most common use cases are GET and POST. Forwards a GET request to a target URL and generates proofs

ANY /proxy

Get Started

Now that we've generated TLS proofs, we can process the data with the Verity Data Processor (VDP) Framework.

Framework

Understanding which Verifiable Data Processing Environment (VDPE) is right for you depends on your use case.
