Over time we have seen our gossip quality degrade as the network has become larger. Over the holidays, we experienced multiple blockchain stalls. Some of these stalls were the result of out-of-memory errors. This 2020.01.05.0 release adds an ARP mechanism to libp2p to pro-actively refresh stale peer book entries. In addition, we fixed a couple of unfortunate typos in PoC receipt validation. We also bumped the assumed valid block to 163,853 for faster resync times.

Deployment Plan

We plan to beta 2020.01.05.0 overnight and confirm that the GA release OTA downgrades successfully before making it available to all hotspots.
