WalkthroughThe pull request introduces several enhancements to the VitePress site configuration and associated documentation. A new "Sequencing" section is added to the sidebar, featuring sub-items for various tutorials. Additionally, new sections are created in several tutorial markdown files, including "Astria Sequencing," "Based Sequencing," and "Forced Inclusion," with placeholder content. A new documentation file for a centralized sequencer is also introduced, detailing its functionality and configuration. Lastly, comprehensive TOML configuration files for the Celestia light client and CometBFT application are added, defining various operational parameters. Changes

1-5: Improve readability with more concise phrasing.The content is technically accurate, but could be more concise.
Consider this revision for improved clarity:
-## Rollkit prior to Sequencing +## Rollkit before Sequencing Rollkit's aggregator node was responsible for selecting and ordering transactions for including in the rollup blocks. The Rollkit aggregator used to follow a FCFS strategy, where every transaction submitted gets included in the block in order without any censorship. Use of a different sequencing strategy or connecting to a sequencing network (e.g., Astria) was not possible. Rollkit `v0.13.8` onwards makes it possible for rollkit to connect to a sequencing network and communicate via grpc.🧰 Tools

Consider expanding the descriptions like this:

- Set

124-126: Consider TLS configuration for production API endpoint.The API server address
tcp://localhost:1317uses plain TCP. For production environments, consider:
- Implementing TLS
- Restricting the listening interface if public access isn't required
219-225: Consider tuning mempool size based on network characteristics.The current setting
max-txs = 5000might need adjustment based on:
- Network transaction volume
- Node hardware capabilities
- Block time and size
Consider monitoring mempool metrics in production to optimize this value.~/.celestia-light-mocha-4/config/config.toml (2)
373-374: Optimize chunk fetchers for better state sync performance.The current setting of 4 chunk fetchers might not be optimal for fast state sync. Consider increasing this value based on available system resources.
Apply this diff to increase chunk fetchers:
-chunk_fetchers = "4" +chunk_fetchers = "8"
470-474: Enable Prometheus metrics for monitoring.Prometheus metrics are currently disabled. For production environments, it's recommended to enable metrics for monitoring and alerting capabilities.
Apply this diff to enable Prometheus metrics:
-prometheus = false +prometheus = true -prometheus_listen_addr = ":26660" +prometheus_listen_addr = "127.0.0.1:26660"Note: Bind to localhost (127.0.0.1) for security unless external access is required.

Consider setting a non-empty minimum gas price.
An empty minimum gas price (minimum-gas-prices = "") could make the network vulnerable to spam transactions. Consider setting a reasonable minimum value based on your network's economics.

The new "Sequencing" section follows the established sidebar structure and maintains consistency with other tutorial sections. The placement between "DA" and "Execution" sections is logical in the context of the rollup stack.

Configure seed nodes for network resilience.
The seeds and persistent_peers configurations are empty. This might affect the node's ability to discover and maintain connections with the network.

13-13: Consider adding a compatibility note.It would be helpful to add a comment above the constant indicating which versions of other components (e.g., rollkit, local DA) are compatible with this sequencer version.

1-4: LGTM! Consider minor style improvements.The introduction effectively explains the transition from FCFS to the new sequencing system. While technically correct, consider rephrasing "prior to" to "before" for conciseness.
