What this looks like

Land titles, vehicle titles, intellectual-property rights, business registers, public credentials — the sovereign system remains the source of truth; the on-chain record mirrors it under the registry-mirror pattern (Pattern B). Mutations on-chain are constrained to those the sovereign system has already authorised; reconciliation is a first-class property of the contract, not an off-chain reconciliation script.

Where citizens hold the credential rather than the asset — driver's licences, professional registrations, academic transcripts, verified addresses — the credential pattern (Pattern C) anchors W3C Verifiable Credentials to on-chain parties via the TDIP identity bridge.

Why a mirror, not a replacement

The sovereign registry is the legal source of truth. The on-chain record exists to make the registry programmable — atomic transfers that respect transfer-tax regimes, eligibility checks at the contract level, verifiable provenance for downstream consumers — without displacing the sovereign record. If the chain and the registry ever disagree, the registry wins by construction.

This matters operationally: the sovereign authority never has to argue with the chain about whose record counts. The chain is downstream of policy, not upstream.

Sovereign DPI composition

Sovereign DPI is being built right now: SL-UDI on MOSIP, India Stack, the EU Digital Identity Wallet under eIDAS-2, GovStack, MOSIP-derived programmes across more than thirty countries. Boli is designed to compose with these rails — credentials issued by sovereign systems flow into Pattern C records, and the TDIP bridge binds them to on-chain parties without requiring the sovereign system to adopt a new identity standard.

Compliance packs encode each jurisdiction's transfer regime, eligibility rules, and supervisory transparency requirements at the chain level. The licensed sovereign authority carries every regulated function; Boli is technology.

Standards used

BSP-0002 (Registry-Mirror Base) defines the on-chain mirror semantics, reconciliation primitives, and sovereign-precedence rules. BSP-0003 (Credential Base) defines verifiable-credential anchoring and TDIP binding. Both inherit the multi-party workflow primitives of the underlying Canton model.
