Roadmap

One app, three deployment targets. Desktop: Electron app — your PC becomes a CKB node with one click. WyBox: flash to an RK3528 TV box (H96 Max), boots into fullscreen kiosk mode, dashboard on HDMI, paired with an ESP32-S3 touchscreen signing remote that holds your keys. SBC: headless Armbian image for Pi/OPi, web UI over LAN. Same codebase, same node stack — CKB full node, Fiber, light client, mining proxy.

C++ wrapper around Nervos' ckb-auth C library. Verify Bitcoin, Ethereum, Cardano, Solana, and 8 other blockchain signatures natively on ESP32. The on-chain counterpart — Omnilock — is already audited and deployed on mainnet. No new lock script needed.

CKB's canonical serialization format for transactions, cells, and headers. Includes Transaction Co-Build Protocol (TCoB) support — structured EIP-712-style signing so an embedded device can display "Pay 100 CKB to alice.ckb" instead of raw hex. Foundation for embedded hardware wallets.

Port of BIP158 compact block filters — lets the CKB light client check if a block contains relevant transactions by downloading a ~1KB filter instead of the full block. Completes the trustless light client.

Port of Nervos' sparse merkle tree (no_std Rust). Verify CKB state proofs, Fiber channel state, and XUDT balances entirely on-device. No trust in any node required.

Port of Nervos' MMR implementation. Verify any CKB block header is part of the canonical chain without downloading all headers. Enables fully trustless checkpoint-based sync on embedded devices.

Optional cloud relay for TelegramOTA — manage a fleet of devices from one bot. One /flash command reaches a named device anywhere. Self-hostable on Fly.io free tier. Extends TelegramOTA without breaking solo mode.

Port of Nervos' Sphinx onion packet implementation to C++ for SBC Fiber nodes. No single hop knows both sender and recipient — full payment privacy. SBC territory (N100, OPi5+), not ESP32.

Fiber uses PTLC (Schnorr + adaptor signatures) instead of HTLC — more private than Lightning Network. Porting the adaptor signature primitives to CKB-ESP32 enables offline payment channel settlement proofs on-device.

Bridge between BitChat's BLE mesh and LoRa radio on T-Deck/T-Beam. Extends the BitChat mesh over kilometres via LoRa. Nobody has shipped this yet. Wire codec and relay engine already implemented in ckb-light-esp.

Payment channel IS the game session. Open channel = game starts, close = final score settled on-chain. FiberQuest implements the first version of this — entry fees over Fiber, RAM-based scoring, autonomous winner payout. Future extensions: streaming micropayments per in-game event, PTLC-based move commitments for trustless turn-based games, spectator bet pools.

A CKB hardware wallet built on ESP32-P4 with a novel hybrid key architecture: everything is stored under SPHINCS+ (post-quantum) protection, but WyVault presents a classical secp256k1 address as a compatibility inbox. Funds sent to the classical address are automatically swept to the quantum-safe vault. Compatible with Neuron via Ledger APDU bridge, and Quantum Purse natively. One device. Always quantum-safe. Works with all existing CKB tooling today — and is ready for the post-quantum future without any migration.

Cryptape's nostr-binding protocol lets any Nostr identity own CKB cells. Nostr uses secp256k1 — same curve as CKB. BitChat-compatible: an ESP32 mesh node could receive CKB payments to its identity with no separate wallet. Bridge between off-grid mesh chat and on-chain assets.

Cryptape proved ZK proof verification is viable on CKB-VM (~130M cycles). Applied to gaming: provably fair randomness, private move proofs, and verifiable game outcomes — all settled on-chain. Extends the Fiber Game Protocol with trustless referees. Extension of Kabletop for modern Fiber.

ESP32 HMI touchscreen POS terminal for CKB payments. QR invoice generation, thermal printer receipt, barcode scanner, Cloudflare Worker payment confirmation. Cross-chain when WyAuth lands.

Run CKB's RISC-V virtual machine on ESP32-P4 — executing CKB lock/type scripts locally. True trustless transaction verification without any node. ESP32-P4 has hardware SHA accelerators and 32MB PSRAM that make this less crazy than it sounds.

A mesh of NerdMiner CKB devices coordinating via the BitChat LoRa bridge — distributed Eaglesong mining without any central server. Nonces partitioned across devices, solution broadcast over mesh.
