After adding an ARP mechanism to libp2p with the release of
2020.01.05.0 on January 6, 2020 we noticed that gossip quality began to degrade again over time. To remedy this we decreased the ARP’s peer staleness time from 24 hours down to 6 minutes and began throttling ARP requests. We also bumped the assumed valid block to 165,353 for faster resync times.
- Fix ARP peer staleness time and add a throttle for ARP requests: PR: libp2p/240
- Add peer refresh CLI command: PR blockchain-core/334
We plan to beta
2020.01.07.0 for a couple of hours starting at 1:45 PM PDT and confirm that the GA release OTA downgrades successfully before making it available to all hotspots.
