[Cardano] - Upgrade to v10.4.1 and Ogmios to v6.13.0

Scheduled for Jun 19, 10:00 - 12:00 UTC

Scheduled

Blockdaemon will update Cardano nodes to v10.4.1 and Ogmios nodes to v6.13.0 on 06/19/25. We are updating our nodes due to a release from the Cardano foundation. This update applies to all Blockdaemon Cardano and Ogmios nodes, there will be planned downtime of up to 30 minutes per node.

Please be aware that the Ogmios release contains the following breaking change:
- queryLedgerState/dump no longer return a hex-encoded CBOR dump as part of the JSON response, but instead, serialise directly to a specified on-disk location.
- queryLedgerState/rewardsProvenance has been renamed to queryLedgerState/stakePoolsPerformances.
- queryLedgerState/rewardAccountSummaries now returns a list of results instead of a map. While this is technically a breaking change, it is necessary to fix scenarios where a credential exist as both script and verification key and would therefore lead to conflict in the key space. The response is otherwise similar to its previous form.

We have tested the release and do not anticipate any unexpected downtime other than mentioned above as a result of the update. If you have any questions or concerns please reach out to your Customer Success Manager.
