kroma-network/kroma v0.3.0 on GitHub

This is a major release for Kroma Sepolia public testnet.

A required flag VALIDATOR_L2_ETH_RPC is added. This flag requires L2 geth RPC, which is for generating proof in challenge process.
Prover communication gateway is changed from gRPC to jsonRPC, so VALIDATOR_PROVER_GRPC is renamed to VALIDATOR_PROVER_RPC.
For consistency and readability, VALIDATOR_OUTPUT_SUBMITTER_DISABLED, VALIDATOR_CHALLENGER_DISABLED are renamed to VALIDATOR_OUTPUT_SUBMITTER_ENABLED, VALIDATOR_CHALLENGER_ENABLED. Both are required flags now.
When creating a challenge, too large bond in the output would put pressure on challenger, so changed the bond amount of each output to a fixed amount. Therefore, VALIDATOR_OUTPUT_SUBMITTER_BOND_AMOUNT is deleted.

🐳 Docker images are available on Docker Hub.
