Advanced Configuration: Pre-Production Testnet

Users wanting to test a cardano-node pre-release version on the pre-production environment may obtain compatible configuration files below.

The latest version available is cardano-node pre-release 10.6.0.

Configuration files

Compatible with cardano-node pre-release 10.6.0

NOTE:
* The new tracing system is now default.  See additional notes below.

* There is no longer a need to maintain separate non-forger and forger config
files.  Node will now intelligently set PeerSharing, and a few other config
parameters based on forging status.

* The legacy non-p2p networking mode is no longer available.

* Avoid connecting PeerSharing enabled nodes to a block producer using
`InitiatorOnlyMode` as the block producer's IP will be leaked.

New Tracing System

As of node 10.6.0 the new tracing system is default. The legacy tracing system is still available, with a legacy config provided above, but is deprecated and will be removed in the near future.

See the 10.6.0 release notes for more information.

Ouroboros Genesis Mode

Ouroboros genesis mode is now the default consensus mode on preview and preprod testnets starting with node 10.5.0. If needed, use of praos mode and the bootstrap peers found in the above topology file can be reverted to by setting:

• Node config's ConsensusMode option to a value of PraosMode

UTXO-HD

Users migrating from a node version older than 10.4.1 should also read the 10.4.1 release notes and the consensus migration guide to properly configure the node and convert the database such that a replay from genesis can be avoided.

Guardrails reference script UTxO

For convenience, the guardrails script has been put on a UTxO so that it can be used as reference script in Treasury Withdrawal and Update Protocol Parameter proposals.
