Ask HN: Ways that financial institutions store ledgers and transactions?
I saw a talk mentioning the use of append-only transactions in a NoSQL database however I was wondering if there was a different way that is more widely used in industry. https://www.advent.com/solutions/geneva-for-hedge-funds/ Stores ledgers and transactions of any instrument: currencies, stocks, bonds, etc. It's developed over the past 30 years, requires financial operations staff to operate. It has a server and client, has an API available. It's expensive to run for startups and hard to transition out of once you use it. Blockchain I believe Symbiont is one of the companies creating/marketing this.
