What is a network upgrade ?

A network upgrade is a change or group of changes to the protocol consensus rules, which are activated at a defined block number. As a consequence, if you adhere to these changes, please upgrade to the new client version before the network upgrade is activated. Otherwise, the non-updated node will remain on an incompatible chain.

How do I upgrade ?

Download and update your RSKj node to Orchid v0.5.0. before the upgrade is activated. This release has already been made available in our Github repo.
