HELLOJUN · ON GITHUB SINCE 2013 Building LLMChain · 2026.10

I'm Jun,
and I've been writing code for a long time.

Years of building exchange wallets, market-making and risk-control systems. For the past two years I've focused on where AI meets Crypto: agents that wager, battle and settle on their own, and AI-assisted market analysis. My current focus is LLMChain: pooling idle LLM capacity on-chain for agents, with a verifiable receipt for every call.

LLMChain: pooling idle LLMs on-chain, for agents

There are plenty of idle GPUs and self-hosted open-weight models out there, and more and more agents firing off thousands of inference calls a day. LLMChain is an independent L1 that connects the two: anyone with a model can list it on-chain; agents pick a provider by model, price and proof tier and pay it directly; every call produces a Verifiable Service Receipt (VSR), and the receipt is the settlement. Humans trade on invoices. Agents trade on VSRs.

01 / SUPPLY

Idle models, listed on-chain

A consumer GPU hosting open weights is enough to list, with no permission needed. The on-chain order book is persistent and states model, unit price, capacity and proof tier.

02 / DEMAND

Agents connect directly, in milliseconds

An agent reads the order book, opens an x402 payment channel, and the provider accepts and executes off-chain on the spot. No waiting for blocks; only settlement goes on-chain.

03 / RECEIPT

The receipt is the settlement

Every completed call produces a VSR, the only object that ever goes on-chain. Funds settle against receipts, with no platform custody.

04 / TRUST

Cheating doesn't pay

Covert challenges, tiered fidelity proofs and stake slashing make swapping a small model in behind a flagship listing a losing trade.

The foundation only builds a thin verification-and-settlement base layer. Revenue splits, routing and the rest of the ecosystem evolve in contracts, driven by the community. Whitepaper v1.1 is just out, with plenty still marked TBD. If you have idle GPUs, or opinions on verifiable inference, payment channels, TEEs or zkML, come file issues, poke holes, and help build it.

Agents × chains: this year's four threads

AI agentsPrediction marketsPython · Vue

PolySport

A sports prediction engine built on multi-agent debate: seven AI analysts with different cognitive biases argue over three rounds, combined with a Zep knowledge graph and Polymarket on-chain smart money, to predict moneyline, spread and totals.

Agent protocolBase · USDCTypeScript

Bout — Open Agent Gaming Protocol

An open battle protocol for AI agents: any agent can register, wager, fight and settle by reading a single Skill file, paying over HTTP via x402. The protocol never custodies keys. Game developers who submit new game types earn a lasting share of fees.

KPAX Ball

Recognizes the match while you browse football markets on Polymarket and gives multi-expert debate analysis in a sidebar. A second line lets you borrow USDC against Polymarket positions, with AI-suggested LTV and auto-close before kickoff.

Market making · QuantGo · Python

Market-making and multi-factor systems

A cluster of Go market-making bots (quoting, hedging, arbitrage, self-trading, risk, alerts), plus the integration of a Python multi-factor backtesting and execution system. A team project; I own the overall design and integration.

03 · THE ROAD SO FAR

Pieced together from commits and repositories on GitHub, this is roughly how it went.

  • 2019

    Starting with wallets

    Wrote my first public project, usdt_wallet, and sent a PR to the EOS token list. I was already interested in how money moves safely on-chain.

  • 2020

    A stint in conventional business

    Built WeChat Native Pay and a smart photo-studio system for a photography brand.

  • 2021–22

    NFTs and games

    Worked on the 1Box NFT platform, the Xoasis NFT marketplace (including an Ethereum wallet SDK for Unreal Engine) and the gamelink chain-game project.

  • 2022–23

    An exchange-grade wallet system

    Started ex-wallet: a complete wallet backend in Go, with deposits and withdrawals, a signing service, a risk service, MPC and KMS, BTC/ETH/BSC/TRON/XRP node integration and an ops console. I wrote the website and part of the admin API myself.

  • 2023

    App chains and DeFi

    Built gchain, a game app chain on the Cosmos SDK, and won first place at the hackathon of the Cosmos HK Accelerator's 2nd Chinese developer training. Also started GreatGainGo, building oracle contracts and nodes.

  • 2023–24

    The inscription wave

    Wrote inscription tools for Celestia, IoTeX and Cosmos, and started CelestLoan and an inscription marketplace. Also wrote a small tool that polls Binance listing announcements every second and goes long on OKX, which unexpectedly became my most-starred repo.

  • 2024–25

    Meme trading and getting into AI

    Started memes-ai, a microservice multi-chain meme-coin trading platform (ETH/BSC/Base/Solana/Tron, with MEV protection). Also built Solana node services, a TradeGPT-style trading assistant, and two Texas Hold'em AIs (one on LangChain, one on the Claude API).

  • 2026

    Agents × chains

    PolySport, the Bout protocol, KPAX Ball, and market-making and multi-factor quant systems. In October, published the LLMChain whitepaper: pooling idle LLM capacity on-chain for agents.
