✨ Release Summary

This version introduces several enhancements, including the experimental Snap Synchronization mode, updates to the Fiat Stable MinGasPrice feature, and improvements to JSON-RPC API compatibility.

Although this upgrade is optional, we strongly recommend updating your node to take advantage of the latest performance and security improvements.

🆕 What's New in RSKj 7.1.0

Here’s a summary of the most notable changes in this version:

  • Introduced SnapSync, a new fast synchronization mode designed to accelerate node bootstrapping [Experimental].
    By @julianlen, @Vovchyk, @asoto-iov, and others in #2233
  • Enhanced Fiat Stable MinGasPrice — added support for defining a valid minimum and maximum gas price range.
    By @asoto-iov in #2922
  • Improved upgrade awareness — added a warning message when a disabled network upgrade is detected.
    By @rmoreliovlabs in #3038
  • JSON-RPC compatibility — added the mixHash and nonce fields to the block DTO, defaulting to zero for compatibility with Ethereum-based tools.
    By @Vovchyk in #2909 and #3135
  • RLP validation enhancement — RLP.getNextElementIndex now throws an exception if an invalid pos value is provided.
    By @rmoreliovlabs in #3052

🔬 Note: Features marked as [Experimental] are disabled by default. These features require further validation or security reviews and may be changed or removed in future releases. If you’re unsure about their implications, we recommend leaving them disabled.

⚡ Introducing the SnapSync protocol

SnapSync is a new experimental feature that allows RSKj nodes to synchronize using a snapshot of the blockchain state, rather than downloading the full history of blocks from genesis. This can significantly reduce the time required to bring a node online, especially as the blockchain continues to grow.

The feature is currently available in experimental mode and is disabled by default. As it is still undergoing validation and security review, its behavior may change or be removed entirely in future releases. We recommend not using this feature if you’re unsure about the implications.

For those interested in testing SnapSync, setup instructions and usage guidelines are available on the Rootstock Developer Portal.
