David Uhumagho Building on CKB

Building payment infrastructure and applications on Nervos CKB. This repo is where the work lives. (Learning and Building in Public)


Weekly Reports

Every week gets a report: what shipped, key learnings, what is pending.


Active Projects

Learn-to-earn game for CKB and Fiber beginners. 9 checkpoints, each requiring a real on-chain action verified against testnet, ending with The Quester: a pixel identity you mint as a Spore so your own bytes live on-chain. Complete them all and earn testnet CKB.

Status: Live on testnet, 9 checkpoints (Checkpoints 4 and 5 await a live Fiber node)
Stack: Next.js 15, TypeScript, @ckb-ccc, @ckb-ccc/spore, JoyID, Groq (llama-3.3-70b)

Write a whole document onto CKB by splitting it across many cells (a manifest cell plus one cell per chunk), encrypted client side and sealed with a content hash. Read any document back from its transaction and prove every byte. The foundation for verifiable certificates: one cell cannot hold a book, so the book is made of cells.

Status: Engine and app built, builds clean, runs on testnet (live signed write and Vercel deploy next). MarkItDown and issuer-signature trust anchor planned.
Stack: Next.js 15, TypeScript, Tailwind, @ckb-ccc, WebCrypto, JoyID and MetaMask


Paused

Fiber-402

HTTP 402 payment middleware powered by CKB Fiber micropayments, started at a hackathon. Weeks 1-3 of the weekly reports cover it. Paused until I can run a live Fiber node; the code stays local until then. Picking it back up is the plan, not a maybe.
