Some nodes on the æternity Mainnet network are currently experiencing issues with acceptance rate of mined blocks.
Upon investigation, the development community find out that the issues have been around for a few days and have deepened.
It is suspected that they are caused by imperfect connectivity between the nodes on æternity’s p2p network.
Two approaches have been applied to address the current situation:
Optimizing the sync algorithm and its handling of the peer list;
Increasing the number of Mainnet nodes. These are non-mining nodes, which help to broadcast blocks. The new nodes will feature optimized sync configuration customized for the current network conditions.
Expect more updates soon.
