Kaia v3.0.0 Release Notice (Kairos Testnet)

Kaia v3.0.0 contains a non-backward-compatible hardfork; Kairos testnet nodes must upgrade to v3.0.0 or later before block 233366400 (estimated 18 Nov 2026, 23:06 UTC+9). The release introduces the Permissionless hardfork, moving validator lifecycle to the AddressBookV2 contract (KIP-286), scoring validators with VRank (KIP-227), and retiring the proxy node (PN) role. Notable operator changes include new kcn valops subcommands, MAXCONNECTIONS raised to 103, the removal of the web3 RPC namespace, and the removal of the --vrank.log-frequency flag.
