IMPORTANT: Kaia v1.0.0 contains a hardfork upgrade that results in changes that are not backward compatible. All testnet nodes must be upgraded to v1.0.0 or later before the target block number.
The Kaia network starts by transitioning the Klaytn network at a transition hardfork. The Kaia Transition hardfork and KIP-160 hardfork configurations are included in this version. The mainnet hardfork block number is planned to be contained in the next version.
Here's the hardfork schedule for the Testnet:
- Block number: 156660000 (estimated time: 13 Jun, 10:13 UTC+9)
- Hardfork contents: Kaia Transition hardfork
Notices
For backward compatibility, the RPC namespaces "kaia" and "klay" are both supported and functionally identical. Similarly, the network selection flags "--cypress" and "--mainnet" are interchangeable, as are the flags "--baobab" and "--testnet."
