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

PANews October 28 news, Kaia v2.1.0 is now online, this update focuses on supporting MEV Auction (KIP-249), improving API and storage performance, while not requiring a Hard Fork. The new version allows receiving BidTx, and external auction parties can pass the winner through a websocket connection (auction namespace), it is recommended to enable websocket and restrict access (firewall or allowlist is recommended). For full nodes, LevelDB defaults to enabling snappy compression, allowing users to reclaim disk space through chain database compression, but this process is time-consuming and increases I/O load. For archive nodes, a new experimental FlatTrie feature has been added, which can be implemented through Erigon-style state layout, but requires re-syncing and some features are temporarily unavailable (such as ethgetProof, real-time pruning, and rollback). Additionally, v2.1.0 introduces RocksDB support, RPC block parameters “safe” and “finalized”, EIP-7702 checking mechanism, as well as more granular compression control and performance, stability optimizations.
