Nyancat Testnet Upgrade


We have released irishub v0.14.3, this new version is to address a weakness in v0.14.1 which, when coinciding with governance parameter setting errors, leads to governance procedures unusable in testnets. We found this problem when trying to go through a governance procedure in Nyancat. However, this problem does not exist in the mainnet, because the mainnet version strictly validates all genesis parameters at startup.

More details can be found here: https://github.com/irisnet/testnets/tree/master/nyancat/v0.14#v0143

We’ll take Bianjie node offline to stop the Nyancat network at 2019-06-24 06:00:00 (UTC),the genesis_time of nyancat-2 is to be discussed here :slight_smile:


What’s the start time for nyancat-2 ?


I think 1 to 2 days after the nyancat testnet stops, so most testnet validators have time to understand and perform this upgrade. So I suggest 2019-06-26T06:00:00.000000000Z


how about 2019-06-26 08:00:00 UTC? 6:00 is the lunch time:smirk:


Is ok for us this time


I think 9pm (Beijing Time) or 13:00 UTC is best for most validators around the world.


2019-06-26 06:00 utc is ok here ! :+1:


This time seems better


Is this time ok with everybody? 2019-06-26T13:00:00.000000000Z (UTC)


Yes, that time is ok to.


Yes is ok. Lets do this
