Blockchain in Advertising: Origins, Applications, and Challenges

·

Introduction

Blockchain technology, hailed by McKinsey & Company as a core innovation capable of triggering the fifth disruptive revolution, has gained exponential traction since 2016. Giants like Oracle, Microsoft, and IBM are accelerating blockchain adoption, while startups proliferate globally. Coindesk projects enterprise blockchain revenue to reach $19.9 billion by 2025, growing at 26.2% annually. The advertising industry is no exception, with IAB forming a blockchain working group in 2018.

Blockchain Fundamentals

Origins and Definition

Emerging from Satoshi Nakamoto’s 2008 Bitcoin whitepaper, blockchain is a distributed ledger technology combining cryptography, consensus algorithms, and smart contracts. It ensures tamper-proof data storage and transparent transactions without intermediaries.

Key Features:

Types of Blockchains:

  1. Public: Open access (e.g., Bitcoin).
  2. Permissioned (Consortium): Controlled by selected entities.
  3. Private: Single-entity managed (e.g., enterprise solutions).

Challenges in Digital Advertising

  1. Ad Fraud: Fake traffic costs advertisers $63 billion annually (ANA, 2015).
  2. Data Silos: Fragmented user data reduces targeting efficiency.
  3. Platform Dominance: Google/Facebook capture 85% of new ad revenue.
  4. User Experience: Intrusive ads drive 600M+ devices to use ad blockers (PageFair, 2017).
  5. Privacy Concerns: 98.5% of Android apps over-collect user data (DCCI, 2017).
