Node Updates

Zephyr Protocol v2.2.0 – Audit Extension

Hardfork v10 has activated at block 511000, re-enabling the Audit state (originally used in Hardfork v8). From this block forward, only audit transactions are permitted. All regular transfers and conversions are temporarily disabled.

This is your final opportunity to have your assets audited. The extension ensures that all services and ecosystem participants complete their audit procedures. The next hardfork, v11, will restore normal functionality and will require another update.

Stay informed through the official Zephyr channels for confirmation on v11 activation and the upcoming build.

Zephyr Protocol v2.2.1 – Wallet Improvements

This optional update delivers several wallet-side improvements and addresses reported transaction issues. Although not mandatory, it’s highly recommended for users experiencing problems with transaction rejection or UTXO synchronization.

Key Fixes and Enhancements:

• Improved transaction broadcasting in chunks.
• Updated UTXO selection logic to handle dust properly.
• Better synchronization behavior after broadcasting a transaction.
• New RPC options for viewing wallet versions and background operations.
• Memory leak fixes, syncing optimizations, and Node.js warning resolution.
• Improved transaction mass policy to prevent rejected submissions.

If your wallet has shown errors related to oversized transaction mass, this update should resolve those issues. Thanks to all community contributors!

Ergo Protocol Reference Client v5.0.25

The latest update to the Ergo reference client brings several useful changes for developers and node operators:

• New API Methods
• bannedPeers config field allows permabanning of specific peers.
• Improved rollback handling and extra index reliability.
• Reworked segment retrieval for better ordering in blockchain-related endpoints.
