🌱 Invisible Garden – Builder Application by Cristóbal Valencia

A repository and project space supporting my application to the Invisible Garden Builder Residency — a six-week immersive experience to co-create the future of Ethereum and open ecosystems.

👤 About Me

CristĂłbal Valencia CerĂłn
🌍 Cali, Colombia 🇨🇴
đź§  Developer Web3 | Full Stack Engineer | Builder @ Ethereum Colombia
đź’ˇ Core Member of Ethereum Cali & Ethereum Colombia (2025)
⚒️ Active in hackathons, DAOs, AI x Crypto, Public Goods & decentralized infra

Since 2023, I’ve been contributing to the Ethereum ecosystem through code, community, and education. I lead technical teams building open-source solutions in:

  • Web3 & DeFi infra (DEX, arbitrage tooling, perpetual dark pools)
  • Blockchain-as-a-Service (BaaS) for document traceability and consent
  • Public-good focused systems (certification tools, off-grid deployments)
  • Local onboarding strategies for LATAM devs

🚀 Why Invisible Garden?

Invisible Garden represents what I value most: intentional building in high-context communities. I want to co-create with people who care deeply about the Ethereum ethos — not just technology, but coordination, experimentation, and long-term positive-sum games.

This residency would allow me to:

  • Collaborate closely with aligned builders and mentors
  • Share lessons from the Latin American Web3 movement
  • Develop impactful prototypes that outlive the six weeks
  • Elevate the visibility and narrative of builders from the Global South

đź”­ What I Want to Build

“Atlas DAO Tools” — An open toolkit for decentralized governance and consent flows, tailored for cooperatives, medical institutions, and public sector use in LATAM.

Core features:

  • Off-chain and on-chain consent registry (IPFS + EVM)
  • DAO-safe document signing and versioning
  • Identity & access permissions with zk/VC integration
  • Multi-language UI for low-connectivity zones

This is the next iteration of systems I’ve been prototyping for:

  • ISO 9001 diagnostic tooling
  • Blockchain-backed consent systems for clinics
  • Offline-first smart city deployments

đź§Ş Tech Stack

  • Solidity + Hardhat + Foundry
  • Next.js + React + Tailwind
  • NestJS + PostgreSQL + Redis
  • IPFS / Filecoin / Lighthouse
  • zkProofs (zk-KYC / Semaphore) – WIP
  • n8n + Lovable + AI agents – experimental

🎓 Scholarships

I’m open to —and grateful for— scholarship support to participate fully in this experience. I aim to bring this knowledge back to the communities and builders I serve across Colombia and LATAM.
