Summary

The Kaiko Data Standard defines a provider-agnostic DAML interface package for publishing and consuming on-ledger data (e.g., prices, reference rates, market indicators) on Canton. It eliminates bespoke bilateral integrations between oracle providers and application consumers, enabling any Canton application to switch or add data providers without DAML rewrites. The Standard is already running in production with institutional clients (Broadridge, Bitsafe, NCFX) and this proposal funds its formal publication into Splice, along with ongoing maintenance, documentation, and adoption incentives.
