Experts Discuss: What Can Blockchain Really Do for Advertising? - ExchangeWire.com

ExchangeWire's 'Experts Discuss: What Can Blockchain Really Do for Advertising?' gathers a roundtable of ad-tech executives to explore how blockchain and related crypto technologies could reshape the advertising ecosystem. The piece surveys potential real-world applications—from fighting fraud and ensuring verifiable data to enabling content monetisation and transparent incentives—while acknowledging that widespread adoption hinges on education, user experience, and integration with existing workflows.

The article highlights public-projects AdChain and Zilliqa slated for 2018, and situates these discussions alongside industry context such as Coinbase's merchant-acceptance product and related micro-payment developments (e.g., Metamask). Quotes from Mike Goldin of ConsenSys Ad Tech, Rob Beeler of AdMonsters, and others frame both the transformational potential and practical hurdles.
