Package upgrade provides a Cosmos SDK module that can be used for smoothly upgrading a live Cosmos chain to a
|
|
new software version. It accomplishes this by providing a BeginBlocker hook that prevents the blockchain state
|
|
machine from proceeding once a pre-defined upgrade block height has been reached. The module does not prescribe
|
|
anything regarding how governance decides to do an upgrade, but just the mechanism for coordinating the upgrade safely.
|
|
Without software support for upgrades, upgrading a live chain is risky because all of the validators need to pause
|
|
their state machines at exactly the same point in the process. If this is not done correctly, there can be state
|
|
inconsistencies which are hard to recover from.
|

For more information, read the documentation on https://docs.cosmos.network/main/modules/upgrade.
