It enables integration with systems outside +the Daml ledger, such as oracles, price feeds, or custom computation services, +while maintaining the deterministic execution guarantees required for distributed +ledger consensus. + +Execution Model and Security Guarantees +--------------------------------------- + +External calls are fully compatible with Daml's execution model and security +guarantees. They maintain deterministic execution and consensus properties +through the following design: + +**Update Monad Integration**: External calls are ``Update`` actions, ensuring +they are properly recorded in the transaction structure. This allows the ledger +to track external interactions and maintain auditability. + +**Question/Answer Interface**: The engine delegates HTTP calls to the participant +via a question/answer interface. This ensures connection pooling is managed at +the participant level and the engine does not make direct network calls. + +**Multiple Extension Support**: Participants can configure multiple extension +services, each with its own endpoint, authentication, and function declarations. +This enables different use cases (oracles, KYC, etc.) to coexist. + +**Deterministic Services**: The external service must be fully deterministic. +Given identical inputs, it must always produce the same output. This is enforced +by requiring all participants to use the same service configuration and/or binary, +verified through the ``configHash`` parameter. + +**Local Execution**: Each participant runs its own local instance of the +external service. This eliminates network dependencies and single points of +failure that could compromise ledger integrity. + +**Transaction Validation**: In Canton, all transactions are validated and +re-executed on all affected participants. When a transaction contains an +external call, each participant independently executes the same call with +identical parameters. The transaction is only accepted if all participants +obtain identical results from their respective service instances. + +**Startup Validation**: On participant startup, the system validates that all +DARs have their extension requirements satisfied by the participant's +configuration. This detects misconfigurations and version drift early. + +Types +----- + +.. _type-da-external-byteshex-28451: + +`BytesHex `_ + \: :ref:`Text ` + + A type alias for ``Text`` representing hex-encoded bytes.
