Upgrade block and date

This upgrade is expected to occur at block 16562500. (Estimate date is April 27, 2023 at 14:00 UTC)

On-Chain Upgrade Process

When the network reaches the halt height, the state machine program of the BandChain will be halted. This classic method for upgrading requires all validators and node operators to manually substitute the existing state machine binary with the new binary. We recommend validators to use Cosmovisor to swap the binaries automatically. Because it is an on-chain upgrade process, the blockchain will be continued with all the accumulated history with continuous block height.
