IOTA, an open-source blockchain network, has teamed up with some of the biggest global corporate names led by Cisco Systems Inc, Volkswagen AG, and Samsung Group to launch what is aimed to be a secure marketplace for data, IOTA co-founder David Sønstebø said to Reuters on Tuesday.

Blockchain is a digital ledger of transactions that underpinned the first crypto-currency bitcoin. It has gained worldwide prominence due to its perceived usefulness in recording and keeping track of assets across all industries.

“The data marketplace is a completely separate project that simply utilizes the underlying IOTA protocol,” said Sønstebø in emailed responses to Reuters.

IOTA is headquartered in Berlin.

China’s Huawei group, a multinational networking and telecommunications company, is also part of the data marketplace project, IOTA said.
