A longer piece, including some alternative suggestions from Gartner:
‘When it comes to supply chains, Valdes believes that blockchains could play an important coordinating role. “If you have a fragmented business ecosystem, with many parties who don’t know each other but need to do business, then they could collaborate through a blockchain,” he says. But there’s a catch. “It’s a ‘boil the ocean’ problem,” he says, meaning that it’ll take fundamental shifts in an industry for adoption to take place. Optimistically, he says, it would take a decade for the industry to rearrange itself so that everyone was logging interactions on a blockchain.
‘Valdes argues that a company as dominant as Walmart doesn’t need its suppliers on a blockchain. It can simply ask its vendors to use whatever system it chooses. “They have been very successful because over the years they have built a robust system of record for their supply chain,” he says. “If you were a supplier to them, you would happily accept their centralized version of the truth.”’
