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.
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.
