when sharding?
When ETH 2.0? Under development ... like everything in crypto... Dunno about sharding ETA but you can find the latest updates here:
https://t.me/IdenaGithub - telegram notifier about every GitHub update. After recent mainnet release (that Andrew decided not to announce - are you scared of hype?) GitHub is on fire. Update few times daily.
Good to here that developement is on fire. Pretty bullish on Idena right now.
Btw is there any mandatory upgrade or hardfork planned as I'm not connected on Discord/Telegram as much as I wanted.
