Kaia v2.1.0 is live, supporting MEV Auction and multiple optimizations

Chaincatcher2025/10/28 08:36

ChainCatcher news, Kaia v2.1.0 is now live. This update focuses on supporting MEV Auction (KIP-249), improving API and storage performance, and does not require a hard fork.

The new version allows receiving BidTx, and external auctioneers can deliver winners via websocket connection (auction namespace). It is recommended to enable websocket and restrict access (preferably using a firewall or allowlist). For full nodes, LevelDB now enables snappy compression by default. Users can reclaim disk space by compressing the chain database, but this process is time-consuming and increases I/O load.

For archive nodes, an experimental FlatTrie feature has been added, which can be implemented using Erigon-style state layout. However, it requires resynchronization and some features are temporarily unavailable (such as eth_getProof, real-time pruning, and rollback). In addition, v2.1.0 introduces support for RocksDB, RPC block parameters "safe" and "finalized", EIP-7702 verification mechanism, as well as more granular compression controls and performance and stability optimizations.
