Configuration files

Compatible with cardano-node release 10.5.1

NOTE:
The non-block-producer node config has `PeerSharing` enabled by
default, so should not be used with block-producers.

Additionally, avoid connecting a block-producer not using p2p to a p2p
PeerSharing enabled relay as the block-producer's IP will be leaked.

• Node Config (Non-block-producers -- see note above)
• Node Config (Block-producers)
• DB Sync Config
• Submit API Config
• Node Topology
• Node Topology (Non-bootstrap-peers)
• Peer Snapshot
• Checkpoints
• Byron Genesis
• Shelley Genesis
• Alonzo Genesis
• Conway Genesis
• Compiled guardrails script

Ouroboros Genesis Mode

For those preferring to use Genesis mode over bootstrap peers, the following requirements will also need to be met:

• The node config file will need to have ConsensusMode set to GenesisMode

• To the topology file, a new key of peerSnapshotFile will need to be added and set to the path of the peer snapshot file, provided above. The declared path can be absolute or relative with respect to the directory of the topology file.

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 Protocol Parameter Change proposals.
