Node Updates
Zephyr Protocol v2.2.0 – Audit Extension
Hardfork v10 has been activated at block 511000, reinstating the Audit state (previously used in Hardfork v8). From this block onward, only audit transactions are allowed. All standard transfers and conversions are temporarily halted.


This is your final chance to have your assets audited. The extension guarantees that all services and ecosystem participants complete their audit processes. The next hardfork, v11, will restore regular functionality and will necessitate another update.
Stay updated via the official Zephyr channels for verification on v11 activation and the forthcoming build.
Zephyr Protocol v2.2.1 – Wallet Enhancements
This optional upgrade offers various wallet-side improvements and resolves reported transaction issues. While not mandatory, it’s strongly advised for users facing difficulties with transaction refusals or UTXO synchronization.
Major Fixes and Improvements:
- Enhanced transaction broadcasting in segments.
- Revised UTXO selection strategy to manage dust correctly.
- Optimized synchronization behavior post-broadcasting a transaction.
- New RPC options for checking wallet versions and background processes.
- Resolved memory leaks, improved synchronization, and addressed Node.js warnings.
- Refined transaction mass policy to avoid rejected submissions.
If your wallet has indicated issues related to oversized transaction mass, this upgrade should rectify those problems. Many thanks to all community contributors!

The most recent update to the Ergo reference client introduces several valuable modifications for developers and node operators:
- New API Methods
- bannedPeers config field permits permanent banning of specific peers.
- Enhanced rollback handling and additional index reliability.
- Revamped segment retrieval for improved ordering in blockchain-related endpoints.
