Summary: The Rootstock (RSK) community has approved a set of consensus changes to be included in the upcoming Fingerroot network upgrade. Fingerroot will activate on RSK Mainnet on block #5,468,000. This is a mandatory upgrade; users who adhere to these changes must update their nodes to one of the latest versions.
What is a network upgrade?
A network upgrade is a set of changes to the protocol consensus rules, which are activated at a defined block number. All nodes in the network need to run a compatible client version implementing these new consensus rules to work properly. As a consequence, if you adhere to these changes, you will need to upgrade to the new client version before the network upgrade is activated. Otherwise, the non-updated nodes will remain on an incompatible chain.
What changes are included in Fingerroot 5.0.0?
The consensus changes included in this version are:
- Transaction gas price cap (RSKIP-252)
- Peg-out events improvements (RSKIP-326)
- Reestablish the number of block confirmations for a PowPeg migration period (RSKIP-374)
- Use the pegout creation transaction hash as the key in the map structure that stores the pegout transactions waiting for signatures (RSKIP-375)
- Store the last retired PowPeg standard P2SH script (RSKIP-377)
- Increase POWpeg activation age (RSKIP-383)
- Bridge method `getEstimatedFeesForNextPegOutEvent` improvement (RSKIP-385)

Is there anything I need to consider when upgrading to Fingerroot 5.0.0?
