The ledger your systems can prove.
Ledgerpost is an append-only ledger and event backbone. Every entry is immutable, ordered, and cryptographically linked to the one before it.
The result is a financial and audit record you can hand to an auditor, not one you reconstruct from application logs after the fact.
Append-only by construction
Entries are written once and never updated in place. A correction is a new entry that references the one it corrects, so the history stays intact and readable.
Double-entry primitives
Accounts, entries, and balanced postings are first-class. You model money movement the way an accountant would reason about it, not as rows you reconcile later.
Verifiable to an auditor
Every entry links to the hash of the one before it. You can hand an auditor a proof that the log was not altered, rather than a promise that it was not.
Three readers, one site
Engineering
A ledger API you post to, with SDKs and webhooks, instead of a schema you maintain.
Finance and compliance
Records that are ordered, immutable, and provable, without a data export project.
