Artemis
Immutable ledger for regulated finance
A distributed ledger where every state change is cryptographically signed and every record is append-only — built for regulators who read specs, not whitepapers.
Request a Demo →Merkle-chained append-only storage
Every block is hashed into the next. Rewriting the past requires rewriting the present.
Ed25519 signed provenance
Every event is cryptographically signed at write time. Attribution isn't ambiguous.
Per-tenant chain isolation
Each client's ledger is a separate chain. Audit scope stays narrow.
Sub-second historical queries
Designed for point-in-time reconstructions of any past state.
The shape of it
Blocks. Hashes. Signatures. Queries that go back to genesis.
What it does
The ledger your CFO and your auditor can both agree on.
Cryptographic provenance
Every event is signed, chained, and timestamped. 'Who changed what, when' isn't a question — it's a query.
Append-only storage
No updates. No deletes. Corrections are compensating entries with a full audit trail. Bookkeeping at the physics layer.
Asset tokenization
Represent any regulated asset as a token — policy rights, commission entitlements, fractional equity. Transfers are atomic and provable.
Regulator-grade querying
Point-in-time reconstructions. Full transaction graphs. Any state at any historical moment, in under a second.
Per-tenant isolation
Multi-tenant without leakage. Each client's chain is cryptographically separate. Compliance audits scope to one namespace.
Not a cryptocurrency
No gas fees. No public chain. No speculative tokens. Just a permissioned ledger running on your infra, doing exactly what you need.
How it works
Three services. Zero mystery.
Submit
Your app posts a transaction. Artemis validates the payload, signs it with your tenant key, and places it in the pending queue.
Commit
Consensus across your nodes. Block is sealed with the previous block's hash. Written once; cannot be rewritten.
Query
Full REST API. Point-in-time. Filtered. Export to standard warehouse formats or straight to your data warehouse. Your auditors will love this.
Under the hood
Proven primitives. Not research projects.
We didn't invent a new consensus protocol. Artemis uses battle-tested pieces — Merkle trees, Ed25519 signatures, log-structured storage — composed for one job: keep a permissioned ledger honest.
No mining. No public chain. No volatile tokens. Just infrastructure that behaves predictably at 2am on a Tuesday.
