Fintech / Infrastructure
LedgerCore
Double-entry ledger infrastructure · open-source transition in progress. An entry that does not balance is never posted, history cannot be edited and money is integers.
My own product, born from running real payments infrastructure. It models holds and releases as first-class entries, materializes balances in the same transaction as the entry, and stores money as integers in minor units with asset and exponent — never floats. History is append-only: you query the timeline instead of interviewing the survivors.
