I'm also in the finance industry. I'll give a concrete example of where I see blockchain technologies helping in my space, regulatory reporting of OTC derivatives transactions: 1. Regulators need to accept transaction reports, volume is in the hundreds of millions/reports/day so they don't have the technical competency to accept reports themselves 2. 3rd parties ("trade repositories") currently provide this infrastructure but regulators are learning that aggregating data across multiple trade repositories with different implementations is very difficult (particularly where dual-sided reporting across different trade repositories occur!); financial institutions are also ending up having to pay far more than cost to comply with regulations because the trade repositories are profit-driven enterprises 3. A private blockchain (e.g. Quorum and/or maybe Hyperledger's PoEL) solves these problems cleanly: a. regulators have confidence that market participants are playing by the rules and not manipulating (or submitting) reports after the fact. For those who don't know, there's a lot of incentive to 'fix missing reports' -- consider e.g. Merrill Lynch being fined 34.5m GBP for not reporting just 2 years worth of transactions [1]; how would a 'distributed database' give regulators confidence when that kind of 'incentive money' is involved in retro-fitting reports? b. market participants are happy because their highly confidential reporting data can delivered to regulators via simple access controls (even after the fact!) and infrastructure costs are fairly split across market participants in proportion to volume, and the industry effectively "self-regulates" itself (rather than trusting 3rd parties), which is generally an attribute of preferred solutions in the finance industry [1] https://www.fca.org.uk/news/press-releases/fca-fines-merrill-lynch-failing-report-transactions https://www.fca.org.uk/news/press-releases/fca-fines-merrill...
