**
Consensus Nodes (CN)**

  • Accept BidTx; Auctioneer connects via WS RPC (namespace: auction) to deliver winners (e.g., auction_submitBid).

  • Enable WS + limit API surface to auction; secure the endpoint (firewall/allowlist).

    • kcnd.conf: WS_ENABLE=1, WS_API="auction"

Full Nodes

  • LevelDB snappy is now default (v2.1.0).

  • For old data, run compaction to rewrite/compress historical segments:

    • debug.chaindbCompact({"preset":"allbutstate"})

  • Expect multi-hour runtime and elevated I/O; disk savings are substantial when combined with snappy.

Archive Nodes

  • Experimental FlatTrie (--state.experimental-flat-trie): Erigon-style state layout.

  • Requires a fresh sync, always archive mode; some features unavailable (e.g., eth_getProof, live pruning, block rewind).

Additional changes

  • RocksDB support

  • RPC block numbers accept safe / finalized

  • EIP-7702 SetCode sanity checks

  • Compaction controls, performance & stability fixes
