Speakers at the event, sponsored by ResultsInternational, from Accenture and Karmarama advised marketers and agencies not to get "too hung up" on finding their own uses for blockchain.
Instead, the question marketers should ask is: "can you take the sense of trust and transparency which are values brands believe they have and want to communicate, and can you use that to tell a progressive story about your brand?" Lawrence Weber, innovation partner at Karmarama, said.
But before brands embark on this, they should also be clear about what it will take to get their supply chain, or their practices on the blockchain, Hugo Pinto, managing director UK and Ireland of AccentureDigital cautioned.
The problem for many businesses, Pinto said, is that "we focus too much on technology and not on how much we need to change to adopt it. There’s no point just taking what you do today and dumping it onto the blockchain."
As far as the media industry is concerned though, blockchain could present a solution to its transparency and trust crisis.
Unilever and IBMiX's blockchain project is already starting to address discrepancy issues while a campaign is running.
Previously, clients often had to wait until the end of a campaign to resolve any discrepancies between what was spent and where it went, Alison Davis, lead industry business development consultant, telco, media and entertainment, IBM, explained.
But can Unilever's buying power be scaled to the point where all parties jump on board?
"Possibly," Davis said. But, why wouldn't an agency or an adtech vendor want to stand up and be recognised for the work they do, she asked.
But is blockchain truly the solution the media industry is looking for? Opinions were divided on a during a lively panel debate on the topic.
Both Mary Keane-Dawson, chief executive of Truth, and Ashley Mackenzie, founder and chief executive of Fenestra are, of course, proponents of the idea that blockchain is part of the solution.
"I think that blockchain can certainly help with bringing transparency to media, but problems in media go deeper and wider," Keane-Dawson said.
It does depend on human buy-in and behaviour, Ruth Zohrer, chief product officer of Mindshare, commented.
The problem is that while blockchain could be a solution, it is not one that will be implemented in the near term, Julie Langley, partner of Results International, said. "There are too many challenges to be overcome."
The debate continued after the event on Campaign's newscast which focused on the question:
