High-level overview of sprint 68​

Peer Sharing​

Karl Knutsson (CF) produces graphs which show how peer sharing usage expands on mainnet.

Peer Sharing: discovered unique peersPeer Sharing: discovered unique peers

Private relays in the last graph are relays which we are not certain that are registered on the chain.

Typed Protocols​

We conducted an investigation whether the new proposed typed-protocols version (see typed-protocols#52 introduces any performance regression. No regression was found when running a cardano-node (v9.1.0 vs a modified version using the new typed-protocols API) the benchmarking cluster. Also no regression was observed when syncing mainnet. The graph below shows accumulated size of block downloaded over time for both nodes:

The following draft PRs are openned:

cardano-cli ping​

Fixed a bug in which cardano-cli ping exited with wrong exit code when a wrong network magic was supplied, see ouroboros-network#4865.

cardano-cli ping will also now report the remote IP address and port when querying the tip:

Tx-Submission​

We continued writing tests for the new tx-submission application.

We started extending typed-protocols codec to have access to both raw bytes and decoded transactions in the tx-submission mini-protocol. See ouroboros-network#4934.
