Orchid v0.6.0 Network Upgrade

The RSK network will be undergoing a planned network upgrade at block number 1,052,700. This is expected to happen on Wednesday, January 9th, 2019. RSK Testnet network upgrade will happen at block number 233,000, expected on the same date.

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 v0.6.0. before the upgrade is activated. This release has already been made available in our Github repo.
