About

A pioneering decentralized ad network occupying a niche at the intersection of blockchain and programmatic advertising, recognized as one of the earliest and most technically mature Web3 ad platforms.

AdEx Network is a blockchain-based platform for transparent, privacy-focused ad exchange that enables advertisers and publishers to trade ad space directly. Its core protocol is designed as a decentralized advertising system that connects the demand and supply sides without unnecessary intermediaries, leveraging blockchain technology, smart contracts, and layer-2 scaling solutions to secure real-time transactions and automate campaign execution. Unlike traditional ad networks, AdEx does not collect user data and store it in the cloud; instead, the platform matches visitors with relevant ads based on preferences and content context, with anonymized preference data stored locally on the user's device. As of 2024, the platform offers advanced targeting, zero-knowledge privacy features, and AI-driven optimization, alongside an improved staking model. Source 1: gate.com — What is AdEx (ADX)?
