The Rootstock community has approved a set of consensus changes to be included in the upcoming Lovell network upgrade. Lovell will activate on Rootstock Mainnet on block 7,338,024. This is a mandatory upgrade; users who adhere to these changes must update their nodes to the latest version. The latest version of the RSKj client is now available for download in the RSKj GitHub repository.
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. Consequently, if you adhere to these changes, you must 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 Lovell 7.0.0?
The consensus changes included in this version are:
- PowPeg Spendability Validation Protocol (RSKIP-419)
- Express the amount value in wei for peg-out-related events (RSKIP-427)
- New pegout creation event including UTXO outpoint values (RSKIP-428)
- Limit the maximum size of initcode and apply extra gas cost for every 32-byte chunk of initcode (RSKIP-438)
- MCOPY instruction (RSKIP-445)
- Transient storage opcodes (RSKIP-446)
