Hello @juleslai,

Thank you for your progress report!

Regards,
Kino on behalf of the Sia Foundation and Grants Committee

mecsbecs · October 8, 2025, 1:35pm

Hi @juleslai, here is the feedback from your technical review with two requested edits:

An error was found: `error TS2322: Type ‘Uint8Array’ is not assignable to type 'BlobPart
Demos and benchmarks cannot be run locally

Once these adjustments are made, this technical review will be complete and payment can be issued for Milestone 4.

juleslai · October 8, 2025, 5:35pm

Thank you for the technical review feedback. Both issues have been resolved:

(1) I had global TypeScript installation that masked the missing dependency. The TypeScript ‘Uint8Array’ is not assignable to type ‘BlobPart’ error has been fixed - pull the latest code, run npm install && npm run build and all TypeScript errors should be gone with 284/284 tests passing.
(2) For running demos locally on Windows, use npx http-server -p 8080 then open localhost:8080/demos/media/browser-tests.html - all 20/20 tests should pass in the browser (100%). The same tests run in Node.js with node demos/media/*.js show 17/17 passing excluding 3 tests that can only run in browser environment due to Node.js Canvas API limitations (see README “Platform-Specific Notes”).

mecsbecs · October 9, 2025, 3:22pm

Thank you for resolving those issues so promptly.

A note from the reviewer for future:

In the Image Metadata Extraction Demo, all dimensions display as 0×0. This may indicate an issue (e.g., corrupted fixtures) that will need to be addressed.

Overall Summary of Grant Achievements

Originally scheduled for 8 months, the grant was delivered 2 months early. Throughout the 6-month grant period, Enhanced S5.js has delivered a comprehensive reimplementation of the S5 client library, exceeding all original requirements and establishing a production-ready foundation for decentralised application development.

Core Deliverables Completed

Path-Based API - Transformed S5’s CID-centric interface into an intuitive file system API with 5 core methods (get, put, delete, list, getMetadata), enabling developers to use familiar paths like /home/documents/file.txt instead of managing raw content identifiers.

HAMT Implementation - Built automatic directory sharding with 32-way branching, activating at 1,000-entry threshold for efficient handling of large-scale directories with O(log n) performance using deterministic xxhash64 distribution.

Advanced Media Processing - Implemented dual-strategy approach (WASM + Canvas fallback) for thumbnail generation with smart cropping, progressive image loading (JPEG/PNG/WebP), achieving 9.79 KB standalone module size through lazy-loading architecture.

CBOR/DirV1 Format - Adopted the new S5 v1 specification with deterministic CBOR serialisation, maintaining cross-implementation compatibility with Rust reference implementation through byte-for-byte matching test vectors.

Comprehensive Testing - Delivered 437 passing tests across 30 test files with real S5 portal integration tests, including 74 Advanced CID API tests, 38 CBOR serialisation tests, and performance benchmarks for HAMT operations.

Extensive Documentation - Created 100+ pages including API reference, tutorials, benchmarks, and examples in mdbook format matching S5’s documentation standards.

Bundle Optimisation - Achieved 61.14 KB full bundle size (59.58 KB core-only) compressed with brotli, 10.6× under the 700 KB requirement. Modular exports enable tree-shaking with separate core (59.58 KB), media (9.79 KB), and advanced (60.60 KB) modules.

Advanced CID API - Implemented content-addressed operations with four essential methods (pathToCID, cidToPath, getByCID, putByCID) enabling hybrid workflows combining path convenience with cryptographic verification guarantees.

Directory Utilities - Built recursive directory walker with cursor-based pagination for stateless iteration through large hierarchies, plus batch operations supporting copy/move/delete with progress tracking and error recovery.

Developer Experience - Added 28 strategic console logs across 6 core modules using [Enhanced S5.js] prefix for easy Chrome DevTools filtering during development.

Production Validation - Demonstrated real-world usage in Fabstir’s decentralised vector database, enabling trustless AI infrastructure by replacing centralised Elasticsearch with S5 storage.

Summary

The Enhanced S5.js grant has successfully transformed S5 from a low-level storage protocol into an accessible, production-ready platform for building sophisticated decentralised applications. By delivering an intuitive path-based API, automatic HAMT sharding, comprehensive media processing, and extensive testing (437 tests), the project has removed significant barriers to S5 adoption.

The beta release (v0.9.0-beta.4) demonstrates the SDK’s readiness for production use, validated through Fabstir’s vector database implementation. With comprehensive documentation, optimised bundle size (10.6× under target), and proven real-world reliability, Enhanced S5.js establishes a strong foundation for the S5 ecosystem’s growth and mainstream adoption.

All deliverables have been completed on or ahead of schedule, with the project now ready for upstream integration into s5-dev/s5.js and community adoption.

What am I most proud of about the work for this grant

What was achieved went far beyond what I originally planned to do. Decentralised vector database was developed quickly thanks to Enhanced S5.js ease of use. Then Enhanced S5.js became integrated into a complete trustless AI stack in Platformless AI. With Sia providing proof of storage, Fabstir’s STARK proofs verifying computation, and everything open source, I’ve achieved what others only promise: AI infrastructure that’s trustless by design.
Your data cannot be spied upon. It cannot be used for training. The computation is mathematically verified. This isn’t about trusting a company’s privacy policy - it’s about cryptographic guarantees.
Enhanced S5.js is the foundation that makes this possible - “turning Sia from storage into a platform for truly sovereign AI.”

Hi @juleslai - your early report is much appreciated but please reformat your final milestone reporting to match the chart breakdown outlined in the Development Guide. Then the team will be able to conduct their final review.

juleslai · November 25, 2025, 8:49am

Done. Please see the Detailed Progress Report section for the chart.

mecsbecs · December 2, 2025, 2:56pm

Hi @juleslai - a question as a result of your review: how long is the PR review process expected to take at this stage?

juleslai · December 3, 2025, 1:40am

Hi @mecsbecs ,
I’ve reached out to Redsolver for an ETA. However, I should note that the PR review timeline is outside my control — Redsolver indicated that he was amazed over all the cool features but overwhelmed by the amount of new files and intends to “slowly merge individual improvements if they make sense as part of the base s5 library”.
From my side, all grant deliverables are complete:

All milestones 1-7 delivered and approved
Milestone 8 documentation complete
PR submitted on 10th November
Final report submitted 24th November

I’ve done everything within my scope. If grant closure is dependent on upstream merge timing, I’d appreciate guidance on this — as it’s not something I can commit to on Redsolver’s behalf.

mecsbecs · December 3, 2025, 4:30pm

Hello @juleslai - makes sense, and thank you for the additional context.

And with this: congratulations, your final technical review was successful!

This grant will be marked as ‘Complete’ here on the Forum and you will be sent an offboarding email soon.
