Translation Quality Review

Language: Czech (cs) | Files reviewed: 24 | Model: Claude Opus 4.6

Quality Score: 8/10

Category	Score	Notes
Brand Name Preservation	10/10	All brand names preserved correctly (Ethereum, Bitcoin, Solidity, Casper, GHOST, Ethash, Scaffold-ETH, thirdweb, Crossmint, etc.)
Technical Accuracy	9/10	Technical terms (ETH, EVM, PoS, PoW, API, RPC, DAG, RLP, SSZ, MEV, ASIC, etc.) all correctly preserved. Code blocks intact. Minor: code comments translated in Ethash file (acceptable for descriptive comments)
Naturalness & Fluency	7/10	Generally fluent Czech. Some sentences are slightly too literal from English but still understandable. Technical jargon handled well with appropriate Czech equivalents.
Terminology Consistency	8/10	Consistent use of Czech equivalents throughout: "důkaz podílem" (PoS), "důkaz prací" (PoW), "slashing", "atestace", "validátor", "beacon blok", etc.

Issues Found

Fixed (4 typos in data-availability/index.md):

• hho -> ho (doubled letter, line 35)
• jednoduchoou -> jednoduchou (doubled letter, line 39)
• jednochý -> jednoduchý (missing letters, line 43)
• se liší od opětovného získání dat liší -> se liší od opětovného získání dat (duplicated word, line 67)

Not Fixed (minor, non-blocking):

• Code comments inside code blocks in the Ethash file were translated to Czech. This is a common Crowdin behavior and is acceptable since the actual code/variable names are preserved.
• Some MDX component attributes (e.g., ExpandableCard title=) remain in English, which is correct since they are rendered dynamically.

Summary

Good quality Czech translation covering consensus mechanisms, data structures, dapps, and data availability documentation. All brand names, technical units, URLs, and code snippets are properly preserved. Four typos were found and fixed in the data-availability file. The translation reads naturally for Czech technical documentation.
