Translation Quality Review

Language: Czech (cs)
Files reviewed: 24 (all files spot-checked, 12 thoroughly read)
Model: Claude Opus 4.6

Quality Score: 8/10

Category	Score	Notes
Brand Name Preservation	9/10	Ethereum, Bitcoin, MetaMask, Solidity, Vyper, ENS, IPFS all preserved correctly. Minor note: "OnlyFans" and "Farcaster" correctly kept in English.
Technical Accuracy	8/10	ETH, Wei, Gwei, Gas/palivo used correctly. One duplicate bullet point replaced wrong content (fixed). Code snippets untouched.
Naturalness & Fluency	8/10	Czech reads naturally overall. Good use of Czech technical vocabulary. Some sentences are long but faithful to source.
Terminology Consistency	8/10	Consistent use of "chytrý kontrakt", "validátor", "stakování/uzamčení". Minor inconsistency between "stakování" and "uzamčení" across files but both are acceptable Czech terms.

Issues Found & Fixed

1. Duplicate bullet point in scaling/index.md and roadmap/scaling/index.md -- the English line "Upcoming changes to Ethereum will provide another ~100-1000x of scaling" was replaced by a duplicate of the previous line about ZK-rollups. Fixed with proper translation.

2. Typo "sxistuje" in web3/index.md line 124 -- should be "existuje" (transposed 's' and 'e')

3. Typo "dospěléi" in web3/index.md line 83 -- should be "dospělé" (extra trailing 'i')

4. Typo "tržištíích" in web3/index.md line 67 -- should be "tržištích" (doubled 'í')

5. Typo "transkaci" in scaling/index.md and roadmap/scaling/index.md frontmatter description -- should be "transakci" (transposed letters)

6. Typo "satkeři" in withdrawals/index.md and staking/withdrawals/index.md -- should be "stakeři" (transposed 'a' and 't')

All 6 issues fixed in commit e63a81d.

Summary

Good quality Czech translations overall. Brand names and technical terms are well-preserved. The main issue was a Crowdin artifact that duplicated a bullet point instead of translating a distinct English line. The remaining issues were minor typos scattered across a few files. No URL corruption, no code translation, and no structural/MDX issues found.
