Vodafone Digital Asset Broker (DAB) has joined the Chainlink network as a node operator after completing a proof-of-concept with Japanese trading and investment company Sumitomo for exchanging trade documents across platforms. The companies hope to improve document transfer and processing of financial transactions in the $32-trillion global trade ecosystem, Vodafone said<\/a>.<\/p>\n The proof-of-concept used oracle network Chainlink\u2019s Cross-Chain Interoperability Protocol (CCIP). DAB \u201cprovide[d] security and interoperability across IoT devices at the edge of a network.\u201d The proof-of-concept showed the potential of Vodafone Internet of Things devices and blockchains to provide data for use in contracts and AI applications. Potentially, a single interface could be created to transfer data and tokens, the company said: <\/p>\n \u201cFor example, a vessel detecting a cargo fire could autonomously relay data to smart contracts via DAB\u2019s platform and CCIP, potentially triggering a marine cargo insurance process.\u201d<\/p><\/blockquote>\n Trade documents are a particular challenge because they may exist on paper or on digital platforms with low interoperability and need to change hands repeatedly.<\/p>\n Related: SWIFT partners with Chainlink for cross-chain crypto transfer project<\/a><\/em><\/strong><\/p>\n International telecommunications company Vodafone launched<\/a> DAB in February 2022 and first used it with Mastercard in a trial in the United Kingdom of an app to help electric vehicle drivers find and pay for the best charging options. <\/p>\n Vodafone teamed<\/a> up with Sumitomo in May. The companies formed a new entity, of which Vodafone held 80%. Vodafone transferred DAB \u2014 as well as intellectual property, contracts, technology and software \u2014 into the new business.
