Follow instructions for configuring Captive Core, and take a look at the SDF quorum set configuration for a list of the current Tier-1 validators.The Stellar TK2100 enclosure features an All-in-One PC and projected capacitive touchscreen with a minimalist bezel, providing a contemporary and sophisticated user interface presentation. Please also make sure to take look at your quorum set configuration, which may need adjusting due to recent changes in network topology. Also note that this version fixes an issue with an earlier version of Core that prevented Captive Core nodes from applying certain ledgers, so if that's happening to you, make sure to upgrade to v19.0.1. That's true even if you run the Captive Core architecture since Horizon uses whatever Stellar Core package you have installed. If that's the case for you, and you would like to keep it that way, you can disable Captive Core by setting ENABLE_CAPTIVE_CORE_INGESTION="false" env variable.Īfter upgrading to the new version of Horizon, Horizon operators also need to upgrade Stellar Core to v19.1.0. While we advise everyone who runs Horizon to deploy the Captive Core architecture, we also understand that some people still rely on legacy architecture and run Horizon along with a standalone Stellar Core node. It should execute pretty quickly because it adds columns that correspond to new account extensions and transaction preconditions introduced in Protocol 19, so it doesn't involve any backfilling.īy default, v2.17.0 runs a mini-Stellar Core (aka Captive Core) as a subprocess of Horizon, so you don't need to run a standalone Stellar Core node. Upgrading also involves a database migration, which is described in the Horizon CHANGELOG. If you are running a pre-v2.17.0 version of Horizon when the network upgrades, it will break as soon as it tries to ingest one of the new transaction preconditions or signature types. Upgrade to Horizon v2.18.0, which has full support for Protocol 19.
