caution
In this documentation, we use the following generic identifiers:
- YOUR_CARDANO_NETWORK You need to replace this with the name of the network that runs on your Cardano node (eg,
preprod) - YOUR_AGGREGATOR_ENDPOINT You need to replace this with the endpoint of an aggregator that runs on the Cardano network you are targeting (eg,
https://aggregator.release-preprod.api.mithril.network/aggregator) - YOUR_GENESIS_VERIFICATION_KEY You need to replace this with the genesis verification key URL that runs on the Cardano network you are targeting (eg,
https://raw.githubusercontent.com/input-output-hk/mithril/main/mithril-infra/configuration/release-preprod/genesis.vkey) - YOUR_ERA_READER_ADAPTER_TYPE You need to replace this with the era reader adapter type used by the Mithril network you are targeting (eg,
cardano-chain) - YOUR_ERA_READER_ADDRESS You need to replace this with the era reader address URL used by the Mithril network you are targeting (eg,
https://raw.githubusercontent.com/input-output-hk/mithril/main/mithril-infra/configuration/release-preprod/era.addr) - YOUR_ERA_READER_VERIFICATION_KEY You need to replace this with the era reader verification key URL used by the Mithril network you are targeting (eg,
https://raw.githubusercontent.com/input-output-hk/mithril/main/mithril-infra/configuration/release-preprod/era.vkey) - YOUR_ANCILLARY_VERIFICATION_KEY You need to replace this with the ancillary verification key URL used by the Mithril network you are targeting (eg,
https://raw.githubusercontent.com/input-output-hk/mithril/main/mithril-infra/configuration/release-preprod/ancillary.vkey)
