Advertising technology company Mediaocean has declared a blockchain partnership with Amino Payments for comprehensive auditing of digital advertising buys.

Mediaocean processes $150 billion a year in advertising spend via its platforms and a year ago announced it had gone live with its blockchain platform created with IBM. The blockchain pilot solution assisted two dozen brands, including Kellogg’s, Pfizer, Kimberly-Clark, and Unilever, and gave $670 million in ad spend.

One of the difficulties in digital advertising is the absolute number of companies included in the ad spend process, which indicates advertisers need clarity into the media supply chain.

Typically if there’s a drive, the ad buy might go through a Demand-side platform, which is a portal to allow the campaign to be expanded across multiple advertising exchanges. But on the other hand, the publisher has the same design, sell-side platforms, which enable them to set their inventory on various transactions.

Mediaocean CRO Ramsey McGrory said that Mediaocean seizes the end-to-end purchase order to payment data. What Amino Payments supplements are the comprehensive breakdown of suppliers. This indicates the buyer can view all the vendors, partners, and fees charged.

So in the comparatively simple three-step illustration above, Amino Payments would deconstruct the data from the DSP, the exchanges, and the SSP. Eventually, brands and agencies will be capable of seeing reports dispensing the suppliers, technology, and data partners included in a transaction, as well as how much money each of them gets.

“Delivering programmatic media supply chain transparency inside the financial and contractual workflow has been one of the top requests we’ve received as we’ve innovated with blockchain,” said McGrory. “The partnership with Amino Payments will help us to deliver this.”

“By combining Amino’s impression-level cost analysis and supply path optimization tools with Mediaocean’s cross-media management solutions, marketers will have complete and detailed visibility of their programmatic buys from purchase order to payment execution,” said Amino’s CEO Will Luttrell.

Mediaocean is also a part of the Adledger consortium, which has issued several reports about blockchain in advertising. There are various blockchain advertising enterprises around the world, including multiple from the Interactive Advertising Bureau.

Others include PepsiCo and Mindshare in the Asia Pacific, and in the UK, Nestlé, McDonald’s, and Unilever are engaging in the JICWEBS pilot.
