Configuration of domain parameters that all members connecting to a domain must adhere to.

To set these parameters, you need to be familiar with the Canton architecture. See the Canton architecture overview for further information.

reconciliationInterval

determines the time between sending two successive ACS commitments. Must be a multiple of 1 second.

maxRatePerParticipant

maximum number of messages sent per participant per second

maxInboundMessageSize

maximum size of messages (in bytes) that the domain can receive through the public API

uniqueContractKeys

When set, participants connected to this domain will check that contract keys are unique. When a participant is connected to a domain with unique contract keys support, it must not connect nor have ever been connected to any other domain.

requiredSigningKeySchemes

The optional required signing key schemes that a member has to support. If none is specified, all the allowed schemes are required.

requiredEncryptionKeySchemes

The optional required encryption key schemes that a member has to support. If none is specified, all the allowed schemes are required.

requiredSymmetricKeySchemes

The optional required symmetric key schemes that a member has to support. If none is specified, all the allowed schemes are required.

requiredHashAlgorithms

The optional required hash algorithms that a member has to support. If none is specified, all the allowed algorithms are required.

requiredCryptoKeyFormats

The optional required crypto key formats that a member has to support. If none is specified, all the supported algorithms are required.

protocolVersion

The protocol version spoken on the domain. All participants and domain nodes attempting to connect to the sequencer need to support this protocol version to connect.
