RSK Arrowhead Release 6.3.1

Summary

This release introduces remediation to the PowPeg service issue in Rootstock Mainnet, as described here.

Since consensus rules have changed, this version is incompatible with earlier versions. 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. The Mainnet network upgrade will happen at block number 6,549,300.

When RSK Arrowhead 6.3.1 successfully activates at Rootstock Mainnet block 6,549,300, the PowPeg service will resume its regular operation and any outstanding peg-in and peg-out operations will be processed.

What's New in RSKj 6.3.1

The consensus change included in this version is:

• Bridge Bitcoin block chainwork up to 12 Bytes (RSKIP-434)

Please refer to RSKIP 436 - Network Upgrade (patch): Arrowhead 6.3.1 for further information.
