But Apple may be the first challenger to throw down the gauntlet to Mark Zuckerberg’s global dominance. Speaking at a private event in San Francisco yesterday, Apple Pay’s vice president – Jennifer Bailey – told CNN reporters that cryptocurrency was on the company’s radar. "We're watching cryptocurrency," she said. "We think it's interesting. We think it has interesting long-term potential."

Although it gave little away in terms of quite what Apple is looking to do in the crypto space, the very suggestion that a popular tech behemoth was even "watching cryptocurrency" added enough fuel to the fires of excitement for global experts.

Many will have made the connection to Apple filing a lengthy submission to the US Securities and Exchange Commission earlier this year pertaining to its desire to commit to human rights throughout its global supply chain.

Deep within the details of the 9,800-word Conflict of Minerals report were suggestions that Apple was actively working on using blockchain technology.

While blockchain can be used effectively as a guarantee of provenance for Apple’s minerals supply, it is also the technology that underpins cryptocurrency.
