Overview of sprints 91, 92​

Cardano-Node changes​

The default value for PeerSharing configuration option in cardano-node-10.5.1 will be:

  • false if the node is configured as a block producer
  • true if the node is configured as a relay

See PR#6284, PR#6274.

We also deprecated cardano-node run command line flag --non-producing-node in favour of --start-as-non-producing-node.

Chain-Sync​

We modified chain-sync timeout implementation. The idle timeout will be chosen randomly each time chain-sync mini-protocol enters StIdle state, while before the timeout was fixed during connection lifetime (although it was still random). This was done to eliminate survivor bias, where long-lived connections were those which had longer timeouts. Now it should be fairer for all connections.

Note that this timeout will be triggered due to a suffciently large gap between consecutive blocks, as a result of Cardano's probabilistic schedule.

See PR#4980.

SRV support according to CIP#155​

We merged SRV support according to CIP#155, see PR#5131.

PeerSharing in InitiatorOnlyMode​

We made it possible to configure PeerSharing on connections which negotiated InitiatorOnlyDiffusionMode. See (PR#5148, Issue#5124).

Releases​
