 "text": "Blockchain state-of-the-art: architecture, use cases, consensus, challenges and opportunities presents the following source proposition: However, the technology is in its early stage and still, there is a range of concerns that are yet to be addressed before its wide adoption. This proposition is pertinent to Kaal's source-bound claim that The Bank of Canada's year long Jasper trial revealed a tradeoff rather than a solution: Ethereum would make the wholesale payment system more resilient but was costly and raised privacy issues, while Corda addressed cost and privacy but made the system less resilient, and the Bank concluded in May 2017 that blockchain was not mature enough to run a national interbank payment system. The proposed response is an extension: the relationship should remain limited to the retrieved source proposition and the mapped Kaal claim unless fuller source review supports a broader conclusion.",
