Translation Quality Review

Language: Bengali (bn) | Files reviewed: 24 | Model: Claude Opus 4.6

Quality Score: 8.5/10

Category	Score	Notes
Brand Name Preservation	9/10	All brand names (Ethereum, ETH, Gwei, Solidity, Vitalik, MetaMask, etc.) correctly preserved in English. One instance of Hindi/Devanagari script contamination found and fixed.
Technical Accuracy	8/10	Code fences generally well-preserved (Python code, variable names, constants all in English). One code fence block had its descriptive text translated to Bengali instead of being left in English — fixed.
Naturalness & Fluency	9/10	Translation reads naturally in Bengali. Consistent formal register throughout. Technical terms use accepted Bengali transliterations (e.g., ইথেরিয়াম for Ethereum, ভ্যালিডেটর for validator).
Terminology Consistency	8/10	Consistent terminology across files. Key terms like ভ্যালিডেটর (validator), কনসেন্সাস (consensus), স্ল্যাশিং (slashing) used uniformly.

Issues Found

1. Hindi/Devanagari contamination (rewards-and-penalties/index.md, line 11): The word "दुर्भावनाপূর্ণ" mixed Hindi Devanagari script (दुर्भावना) with Bengali script (পূর্ণ). The English source says "malicious intent". Replaced with fully Bengali "দুর্ভাবনাপূর্ণ".

2. Translated text inside code fences (rewards-and-penalties/index.md, lines 34-38): A descriptive list inside a code fence was translated to Bengali. Code fence content should remain in English to match the source and avoid confusion. Restored to English original.

Fixes Applied

1. Replaced mixed-script "दुर्भावনাপূর্ণ" with Bengali "দুর্ভাবনাপূর্ণ" in rewards-and-penalties/index.md
2. Restored English text inside code fences in rewards-and-penalties/index.md (5 lines)

Summary

Overall high-quality Bengali translation covering proof-of-stake consensus mechanisms, mining algorithms, dapps, data structures, and data availability topics. The 24 files are well-translated with consistent terminology and natural fluency. Only one file (rewards-and-penalties/index.md) had issues: a Devanagari script contamination and translated code fence content, both now fixed.

Translation Quality Review — Bengali (bn) Part 03

Score: 8.5 / 10

Files Reviewed

24 files covering developers/docs/consensus-mechanisms/ (PoS and PoW), dapps/, data-and-analytics/, data-availability/, and data-structures-and-encoding/.

Categories

Category	Status
Translated code in fences	Fixed (9 code blocks)
Brand names in Bengali script	Pass — Ethereum kept in English in code/links
Broken HTML/MDX	Pass
Crowdin artifacts	Pass
Hindi/Devanagari contamination	Pass
Frontmatter structure	Pass
URLs with Bengali chars	Pass
Line count parity with English	Pass

Issues Found & Fixed

Translated code comments (FIXED) — Crowdin translated Python code comments inside fenced code blocks in two files:

1. ethash/index.md — 6 code blocks had Bengali comments (constant definitions, cache generation, dataset calculation, main hashimoto loop, mining function, appendix utilities)
2. dagger-hashimoto/index.md — 3 code blocks had Bengali comments (encode/decode docstrings, parameter definitions with inline comments, double-buffer conditional comment)

All 9 affected code blocks restored to English source to preserve reference implementation correctness.

Commit: 3066756 — fix(i18n): restore English code comments in Bengali translations

No Issues Found

• 22 other files are clean translations with no syntax or content issues
• Frontmatter title/description fields properly localized
• All internal links preserved correctly (English URL paths)
• MDX components (<Alert>, etc.) properly structured
• Technical terms appropriately handled (mix of transliteration and English retention)

Summary

Solid batch of Bengali translations for technical documentation. The only systematic issue was Crowdin translating code comments, which is a known behavior for content-heavy algorithm pages. Fixed and pushed.
