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

ChainCatcher message, Kaia v2.1.0 is now live. This update focuses on supporting MEV Auction (KIP-249), enhancing API and storage performance, all without a hard fork.

The new version allows for receiving BidTx, and external auction participants can pass the winner through a websocket connection (auction namespace). It is recommended to enable websocket and restrict access (using a firewall or allowlist is recommended). For full nodes, LevelDB enables snappy compression by default, 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 resynchronization and some features are temporarily unavailable (such as eth_getProof, real-time pruning, 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 and stability optimizations.
