ev-node v1.0.0-rc.1

This release candidate introduces forced inclusion and batch sequencing capabilities, adds new batching strategies, and includes several breaking changes that improve code clarity and metrics simplicity. Operators should carefully review the breaking changes section and plan for required configuration updates.

Tested upgrade paths

• ev-node v1.0.0-beta.11 -> ev-node v1.0.0-rc.1

⚠️ Breaking Changes

1. Genesis Configuration Update Required

What changed: Implemented forced inclusion and batch sequencing system that requires a new genesis configuration field.

Action required:

1. Open your node's genesis.json file
2. Add the following field: "da_epoch_forced_inclusion": 100
3. The recommended value is 100 (this represents the number of epochs)
4. Save the file and restart your node

Reference: #2797

2. Signer Path Configuration Update

What changed: Renamed evm-single to evm and grpc-single to evgrpc for improved clarity.

Action required:

1. Open your evnode.yaml configuration file
2. Locate the signer.signer_path field
3. If it contains evm-single, replace it with evm
4. If it contains grpc-single, replace it with evgrpc
5. Save the configuration file

Note: This change may require manual modification if your $HOME folder path has changed.

Reference: #2839

3. Metrics Removal

What changed: Removed unused and confusing metrics from sequencers and block processing. This includes:

• Sequencer-specific metrics (gas price, blob size, transaction status, pending blocks)
• Channel buffer metrics
• Overly granular error metrics
• Block production categorization metrics
• Sync lag metrics

Essential metrics for DA submission health, block production, and performance monitoring are retained.

Action required:

1. Review any monitoring dashboards or alerting rules that depend on the removed metrics
2. Update Prometheus queries to use the retained essential metrics
3. Remove or update any alerts that reference the removed metrics
4. Test your monitoring setup to ensure critical operational visibility is maintained

Reference: #2904

4. DA Client Package Removal

What changed: Removed the core/da package and replaced DAClient with internal implementation. The DA client is now exposed as block.FullDAClient, block.DAClient, and block.DAVerifier without leaking implementation details.

Action required:

1. If you have custom code or plugins that import core/da, update them to use the new interfaces:
   • block.FullDAClient
   • block.DAClient
   • block.DAVerifier
2. Review and test any custom integrations that interact with the DA client
3. Recompile any custom code or extensions

Note: This primarily affects users with custom code integrations. Standard node operations are not affected.

Reference: #2910
