Validator Node Operations¶

Reward Minting and Traffic Funding¶

Sketch:

make your validator node party the featured exchangeParty
the validator app will automatically mint the validator and app rewards for that party
setup automatic traffic purchases in the validator app
optional: setup auto-sweep to your treasuryParty to limit the funds managed by the validator party for that party

Setup Exchange Parties¶

Setup up the featured exchange party¶

Sketch:

this is automatically setup as part of setting up your node
you can retrieve validator party from /v0/validator-user from the Validator API
- TODO: package this up into the wallet SDK

Setup the treasury party¶

Sketch:

Use the wallet SDK to Create an External Party (Wallet) with a key managed in a system of your choice
use the Ledger API to create a #splice-wallet:Splice.Wallet.TransferPreapproval:TransferPreapprovalProposal (code) directly with the provider set to your exchange party

TODO: wrapper in wallet SDK

.dar File Management¶

Sketch:

upload using the Ledger API: https://docs.digitalasset.com/build/3.3/sdlc-howtos/applications/develop/manage-daml-packages.html

Backup and Restore¶

Sketch: considerations when restoring from a validator node backup

offsets change ==> put tx history ingestion into recovery mode and use the last ingested update-id to re-synchronize

Rolling out Major Splice Upgrades¶

Sketch:

See splice docs for context: https://docs.dev.sync.global/validator_operator/validator_major_upgrades.html
like backup and restore above, but with a hard resynchronization to restart from offset 0
determine the offset as of which the ACS export for the hard migration is taken, and ensure that your Tx Ingestion has ingested that before resynchronizing to the newly deployed validator node
