I am a software engineer, innovator, doer, and Mr. Curious. I've been digging into the web3 industry for many years, and I love the equal, transparent, and decentralized nature of web3. I am committed to advancing the web3 industry around the world.

These days I work across distributed systems, verifiable logical clocks (VLC), high-performance blockchains, AI ↔ payments rails, and Lightning Network infrastructure — mostly as an open-source contributor to Hetu Project and Loka Network.

I'm also interested in applying modern mathematical principles and related algorithms to engineering, and in basic sciences such as sociology, economics, organization management, and mathematical physics. I have a positive and healthy attitude, am inclusive, and hold a firm belief in lifelong learning.

Previously, I received my master's degree in Software Engineering at East China Normal University and my bachelor's degree in New Energy Science and Engineering at Jiangsu Ocean University.

# Experience

# What I'm Building (2024 – 2026)

# Hetu Project — Causality-driven infrastructure for the AI-native economy

• hetu-chain — The mainnet interface of the Hetu subnet ecosystem (Cosmos-SDK + EVM, evolved from Evmos).
• Setu — A causally-driven distributed ledger system designed for AI-native economies (Rust).
• causalitygraph — Decentralized data-collaboration network that achieves fast, verifiable causality and data consistency off-chain.
• prakasa — Decentralized, privacy-preserving P2P GPU inference network built on Parallax.
• hetu-checkpoint — Verification network providing multi-dimensional security guarantees.
• aegean-consensus — BFT consensus protocol for multi-agent LLM systems.
• PoCW — Proof of Causality Work — a protocol I helped iterate on for verifiable causal computation.

Earlier work on Hetu also included VLC / TEE-VLC / Chronos / zchronod — research and engineering on verifiable logical clocks running inside AWS Nitro Enclaves, integrated with libp2p, Sui's Mysticeti and FastPay-style protocols.

# Loka Network — Lightning-Network–native AI payment rails

• loka-chain — Fully EVM-compatible chain with NeoBFT consensus and Block-STM parallel execution (forked & re-architected from Cronos).
• loka-p2p-lnd — Agentic-payments P2P Lightning node built natively on top of the Bitcoin Lightning Network.
• paycli — Single-binary Payment CLI + Go SDK for L402 / Lightning payments (the basis of lokapay).
• loka-prism-l402 — Reverse-proxy gateway that turns any API into a metered, micropayment-secured endpoint over HTTP 402.
• agents-pay-service — Open-source Loka agentic Lightning-payment system for multi-agent AI, built on LNbits.
• loka-nostr-middleware — High-performance Rust Nostr relayer used by the Loka payment stack.

# Personal open source

• obsidian-wechat-public-platform ⭐ 150 — Publish Markdown notes from Obsidian straight to WeChat Official Account / 百度百家号.
• iso-relayer — A high-performance, scalable ISO-relay for Nostr.
• gluex — A small Solana-stack experiment for cross-protocol glue in web3.
• ai-chen2050.github.io — Source code of this site (forked from vuepress-theme-gungnir and heavily modified).

# Earlier highlights (2017 – 2023)

# 2023 · KAMI Vision — DePIN / Web3Cam

• zkCam — A decentralized identity & video-evidence platform for IoT cameras: W3C DID + Schnorr ZKP authentication, proxy re-encryption for end-to-end sharing, on-chain integrity proofs. Designed the white-paper, the user / device / share-event data model and built most of the cloud-side APIs.
• Decentralized CDN (DCDN) — Researched Fleek / Saturn / Crust / IPFS-Cluster, then built a multi-node Gateway → IndexProvider → L1-node DCDN pipeline (libp2p + DHT discovery, BadgerDB index, multi-strategy cache, IPFS Cluster storage). Owned the L1 node, Gateway routing and the JSON-RPC interfaces between modules.
• OTA & sharing service — Device OTA flow, proxy-re-encryption sharing, OSS alarm event pipeline, AWS SES email channel, multi-Edge user/sharing/billing APIs.

# 2022 · Amber Group — On-chain alpha & MEV infrastructure

• Alpha Explorer — Amber's in-house MEV / NFT-Arb detector & PnL visualiser (Go, Task-Pipeline arch, MongoDB + Grafana). Owned the NFT-Arb mode end-to-end: ERC-721/1155 event parsing, profit calculation, OpenSea / LooksRare / X2Y2 / sudoswap / NFTX coverage, Grafana dashboards, and bridged in marketplace API keys.
• Chain-node optimisation — Optimised Fantom & Tron full nodes for the searcher stack: P2P broadcast tweaks, event subscription, pending-tx push, plus a hand-rolled Tron Go SDK (none existed officially) so the trading team could quantify on SunSwap / JustLend.
• ETL & observability — Built a Pulsar / ClickHouse / InfluxDB / Grafana / Tableau data pipeline for multi-chain (ETH/BSC/Polygon/FTM) buried-point collection, Dex-swap / lending-liquidation / Top-bot dashboards.

# 2020 – 2022 · Jiansu Network Tech — BEVIOS consortium chain

• BEVIOS — A graphene-plug-in consortium-chain base shipped to 上海一网通办, 东方网 (digital-copyright traceability), and Shanghai Jinghua's NFT trading platform. Features: pluggable consensus (Raft / Async-Pipeline-BFT / BEVY), DAG-driven parallel execution, TEE-based privacy compute, WASM + EVM dual VM, commercially-metered resources (DPU / Bandwidth / dRAM / dROM), K8s/Docker BaaS deployment.
• Personally drove tech selection (vs. Fisco-BCOS / ChainMaker), built the HistoryLog sync tool, integrated PostgreSQL to power a block explorer, added EVM-VM support, and shipped several system contracts.

# 2017 – 2020 · Distribution / Ontology — Custodian & wallets

• Custodian — A B2B multi-currency digital-asset custody platform (BTC / ETH / EOS / ...). Built the new-currency wallet backend (Go Chain Engine + Java business side, RESTful, MySQL + Redis): node sync, deposit parsing, Ledger-backed legal-address generation, withdrawal, reconciliation and risk-control checks.
• Earlier — built Ontology / Neo ecosystem tooling and contributed to wallet core dev for the team.

# Publications

• Patent — A general-purpose WASM contract virtual machine technical solution for cross-blockchain contract ecological integration and reuse.
• Patent — A real-time, online, multi-instance blockchain runtime VM intelligent management & control platform.
