Configuration files

Compatible with cardano-node pre-release 10.3.1

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.

Ouroboros Genesis Mode

For those preferring to use Genesis mode over bootstrap peers, the Genesis mode topology file given above can be used in place of the default topology file. The following requirements will also need to be met:

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

• The peer snapshot file, provided above, will need to exist at the path declared at peerSnapshotFile in the genesis mode topology file: an absolute path, or a relative path with respect to the node server invocation directory

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.
