General Updates 🎙️
Concordium Protocol Version 5 is in effect
Protocol Version 5 was effective from December 13th, 2022 (since this block). Notable changes include pay day for rewards shifting to 08:05 UTC instead of 08:00 UTC.
The protocol change adds support for upgradable smart contracts and allows smart contracts to query additional data from the chain. The protocol update also allows smart contracts to use more resources and introduces a major reorganisation of the account storage. The reorganisation allows for more efficient account retrieval and updates.
Node runners are strongly recommended to subscribe to the Concordium Status Page.
