Tally Platform is a versioned, durable API for managing business identity state. It stores structured identity data as an immutable ledger of snapshots and gives you cryptographic tools to verify that state has not been tampered with.

What you can do

Write identity state

Create and update structured identity records for organization and individual subjects via RFC 6902 JSON Patch operations.

Read with access control

Grant counterparty tenants scoped read access — latest state, full lineage, diffs, or specific versions.

Verify integrity

Each snapshot is hashed (RFC 8785 + SHA-256) and chain-linked. Verify any snapshot or the full chain independently.

Track attribute provenance

Every attribute carries per-field metadata — source type, verification timing, and attesting actor.

How it works

Identity data is organized around subjects (an organization or individual) with a tenant as the accountable owner. Each write creates a new immutable snapshot. Snapshots are hash-linked into a chain that any party can independently verify. Counterparty access is explicit — you grant specific scopes to specific tenants. Nothing is shared by default.
