Blocksize Oracle Lineage & Rights Evidence Index

Evidence as of July 22, 2026. This is a product and sourcing control artifact, not legal advice.

Executive Summary

The index covers 34 providers and 34 distinct lineage groups. For 25 providers, a commercial redistribution grant is not stated in the reviewed public evidence. Public APIs, onchain contracts, and signed reports can establish technical access or provenance, but they do not by themselves grant Blocksize the right to redistribute the data.

Key findings

Source categories span venues, oracle networks, issuers, commercial market-data partners, and infrastructure. Their values are not interchangeable: executable books, reference marks, issuer NAV, and oracle aggregates need different labels and quality gates.

Public documentation most often leaves commercial redistribution unstated or agreement-scoped. That is a diligence queue, not evidence that use is forbidden or granted.

Lineage groups prevent false source diversity. A vendor aggregate, its component venues, and a downstream oracle report cannot automatically be counted as independent confirmations of the same price.

Provider lineage and rights evidence
Provider	Category	Lineage group	External rights evidence
Aevo	Venue	aevo_native_book; options and perps separate from external index/oracle lineage	Not externally documented
Alchemy	Managed Rpc Infrastructure	alchemy_rpc_transport; preserve the underlying chain/protocol lineage	Restricted / not granted
API3	Oracle	api3_beacon_set; each API provider can be lineage-tagged, but an aggregate dAPI is one composite	Not externally documented
Aster	Venue	aster_native_book; do not conflate Aster source with upstream oracle/index	Not externally documented
Chainlink Data Feeds / SmartData	Oracle	chainlink_aggregate; SmartData/NAV must keep issuer administrator lineage; multiple chain deployments are not independent	Not externally documented
Chainlink Data Streams	Oracle Commercial	chainlink_streams; correlated with Chainlink feeds if overlapping upstreams	Agreement or license required
Chronicle	Oracle	chronicle_aggregate; source identities/quality tier should remain attached	Not externally documented
Databento US Equities	Commercial Market-Data Partner	databento_dataset_plus_underlying_venues; a vendor composite is not independent from its licensed venue inputs	Agreement or license required
Dinari	Tokenized Issuer Broker	dinari_sip_or_dfn; official-exchange lineage, not independent from CTA/UTP or other SIP vendors	Agreement or license required
Drift	Venue	drift_dlob; vAMM and indicative-quote components must remain tagged and not counted as independent	Not externally documented
Franklin Templeton / Benji	Tokenized Issuer	franklin_transfer_agent_nav; all chain deployments are one fund/TA source	Not externally documented
Gains Network	Venue	gains_don_reference; do not treat pair price as venue book depth	Not externally documented
Hyperliquid / HIP-3	Venue	hyperliquid_native_book; each HIP-3 dex and its deployer oracle must retain separate lineage	Not externally documented
Matrixdock	Tokenized Issuer	matrixdock_issuer_quote; external Chainlink XAU/USD or SmartData may be upstream and must be tagged	Not externally documented
Midas	Tokenized Issuer	midas_reference_oracle; verification agent and issuer oracle are not separate price sources	Not externally documented

Recommended next steps

Attach executed contract or license references to each production source.
Keep executable, indicative, oracle, NAV, and derived price semantics explicit in every receipt.
Require lineage-group checks before consensus calculations.
Reconcile the internal policy register against external documentary evidence and counsel-approved decisions.

Further questions

Which high-value providers can supply a written redistribution and signing grant? Which apparent independent sources share an upstream index, venue set, issuer NAV, or oracle aggregate?

Caveats

The external matrix summarizes public materials and is not legal advice. The internal rights register is a policy-state input and may encode approvals not visible in public documentation; it must not be presented as an external contractual grant without the supporting agreement.
