10G is not an absolute requirement, if you have a dedicated 1G, it might be okay. But I donât have any field testing data, as we are mostly using AWS, which has 10G as the server side bandwidth.
Monthly bandwidth for a leader node should be higher than a normal validator node. Noted, to put your node in the allowlist doesnât mean you will be the leader all the time. In most cases, it wonât be the leader unless in extreme cases, the internal leaders are rotated to the allowlist one. However, this is the first step to prepare for a fully decentralized network for external leaders. We also plan to do leader rotation after that.
28c shall also work as it is not really the hard bottleneck. What I put there is because of the fixed configuration in AWS.
