Show HN: An API to store balances and transactions Hey everyone! I'm Rob and I want to share what I've built - a solid ledger behind simple API: https://decimals.app https://ift.tt/3ccWImg The ledger is a key piece of any financial system and is easy to get the design wrong, resulting in troubles for making sure money movements are adding up. I took a lot of inspiration from good designs from Square, Uber, and others for the scalability and security aspects. And on the usability side, I applied many concepts from the Ledger CLI, making very easy to use. I'm really happy I get to show this to you all, thank you for reading about it! Please let me know your thoughts and questions in the comments. [1] https://ift.tt/2BeYyRr [2] https://www.youtube.com/watch?v=iN6mhI5hFt4 [3] https://ift.tt/35EKssz May 29, 2020 at 03:48PM
