Kaia v2.1.0 Update Enhances MEV Auction Support and Performance

According to PANews, the latest update for Kaia, version 2.1.0, has been released, focusing on supporting MEV Auction (KIP-249) and improving API and storage performance without requiring a hard fork. This new version allows the reception of BidTx, enabling external auctioneers to transmit winners via websocket connection in the auction namespace. It is recommended to enable websocket and restrict access using a firewall or allowlist. For full nodes, LevelDB now defaults to snappy compression, allowing users to reclaim disk space through chain database compression, although this process is time-consuming and increases I/O load. For archive nodes, an experimental FlatTrie feature has been introduced, which can be implemented through Erigon-style state layout but requires resynchronization and temporarily disables some functions such as eth_getProof, live pruning, and rollback. Additionally, version 2.1.0 introduces support for RocksDB, RPC block parameters 'safe' and 'finalized', the EIP-7702 verification mechanism, and more refined compression control along with performance and stability optimizations.
