Upgrade Codename: Vigorous-Grow-fix - v1.6.1
- Fix AntiSpam new feature at Gov Proposals


On 02-03-2023 at height 7.467.420 our chain was upgraded to v1.6.0 under the codename Vigorous Grow.
In the past few days a bug surfaced where transactions could be sent without consuming gas (see it like gasoline for your car or electricity for your mobile phone).
This caused problems for the validators securing our chain, since every transaction needs to consume gas, regardless of the fee paid for the gas consumed.

This bug makes it impossible for new nodes to synchronize to the chain, and also causes nodes to crash if they restart. Also we experimented some issues with failed TXs. This is not desired of course, which is why we created a fix. We coordinated with several parties to troubleshoot, thanks to the Cosmos SDK group, Notional and Informal Systems.

With this proposal we set a new upgrade height at block 7585420 (10-03-2023 around 18:40h CET) with the codename vigorous-grow-fix (v1.6.1). At the given height the chain will halt and all validators have to change the binary to the new version. After a brief downtime the chain will resume operations.
