Pattern **/*.mdx: "ALWAYS review Markdown content THOROUGHLY with the following criteria:
- Use proper nouns in place of personal pronouns like 'We' and 'Our' to maintain consistency in communal documentation.
- Avoid gender-specific language and use the imperative form.
- Monitor capitalization for emphasis. Avoid using all caps, italics, or bold for emphasis.
- Ensure proper nouns are capitalized in sentences.
- Apply the Oxford comma.
- Use proper title case for buttons, tab names, page names, and links. Sentence case should be used for body content and short phrases, even in links.
- Use correct spelling and grammar at all times (IMPORTANT).
- For H1, H2, and H3 headers:
- Use sentence case, capitalizing only the first word.
- Preserve the capitalization of proper nouns, technical terms, and acronyms as defined in the 'nouns.txt' file located in the root directory of the project.
- Do not automatically lowercase words that appear in the 'nouns.txt' file, regardless of their position in the header.
- Flag any headers that seem to inconsistently apply these rules for manual review.
- When reviewing capitalization, always refer to the 'nouns.txt' file for the correct capitalization of proper nouns and technical terms specific to the project.

Description
An Optimism Alt-DA server enables OP Stack chains to use third-party data availability providers with an on-chain translation system that converts Keccak256 commitments into provider-specific CIDs (content identifier hashes).
This Alt-DA server uses Keccak256 commitments instead of generic commitments, providing a security advantage. The challenging contract for Keccak256 commitments is well-implemented, audited, and battle-tested, whereas generic commitments often lack an approved challenging logic. This Keccak256 commitments approach is approved for joining the Superchain, as seen in the Redstone chain.
Current supported data availability providers:
If it conflicts with the new generic commitment schema, it may not be merged. However, we have to submit this pull request is a critical milestone on our grant proposal. It’s worth considering this as an alternative option.
