Blockchain in Health Data Systems: A Survey should be assessed against 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 current metadata indicates a plausible connection through blockchain governance, but the defensible response is a qualification until the source text confirms agreement, scope, methods, and limitations.

Affirmed commentary position. This record extends a source-bound scholarly claim but is not a verbatim paper claim.
