v2.0.0

Major Changes

This upgrade mainly includes the transition of validator system from ETH-based to KRO-based. KRO-based validator system is Delegated Proof of Stake (DPoS) system based on Kroma's governance token (KRO) and Kroma Guardian House (KGH) NFT. For more details about the new validator system, please refer the specification.

After the transition to the KRO-based validator system, existing validators will no longer be able to operate as validators. To continue participating in the validator network, the validators should upgrade their node to v2.0.0 and register to the KRO-based validator system. The activation time of KRO-based validator system is as follows:

• Kroma Mainnet: after Wed Oct 30 2024 05:20:00 UTC (from output index 10107)
• Kroma Sepolia: after Tue Sep 10 2024 06:04:12 UTC (from output index 129446)

This upgrade is optional for full node operators other than validators.
