🏔️ Celestia Heads to ETHDenver 2025
ETHDenver returns in February 2025 — and Celestia is showing up with an energy only a mammoth could carry. This year’s schedule brings a mix of community games, modular sessions, ZK hacking, and off-chain experimentation.
If you're headed to Denver, here’s what to watch for.
🦣 The Mammoth Hunt Begins
A mysterious capsule will be hidden at the start of ETHDenver, and it won’t be easy to find. Inside: a Mammoth NFT awarded to the first person to scan the QR code. Clues will drop on Celestia’s X (Twitter), so keep those notifications on — and eyes open.
💡 Tip: The capsule drops early. Be there, be curious, and maybe be lucky.
🔧 Modular Day Returns with "Alt Everything"
February 26, 2025 | Co-hosted by Movement Labs & The Rollup
Modular Day is back — this time diving into all things "alt": alt stacks, alt coordination, and alternative futures for modular systems. Expect lightning talks, panel debates, and an open-ended vibe.
Whether you’re shipping a sovereign rollup or still figuring out what a blob is, Modular Day has something for you.
📍 Date: February 26
🏗️ Hacker House: Upgrade the Internet
February 26–28 | With Succinct, Conduit & Celestia Labs
A 3-day builder experience focused on ZK and emerging rollup infra. There are two tracks:
- Open Track – Work on any frontier project using modular components
- Mammothon Track – Build for Celestia with a chance at extra prizes
💰 Top projects get $10K in prizes
🧠 Mentorship from protocol teams and core devs
🧪 Provable Denver: The Future of Off-Chain Computation
February 26 | Co-hosted by Boundless & Hashflow
Provable explores the boundary between what’s on-chain, off-chain, and provable in between. Expect sessions on:
- Zero-knowledge proofs in production
- Decentralized verifiers
- AI x Proof systems
- Off-chain infrastructure design
Whether you’re deep in zk-SNARKs or new to proofs, it’s a brain-expanding half-day of future-facing talks.
🔑 Why This Matters
ETHDenver is one of the most vibrant hacker events of the year. Celestia’s presence in 2025 signals a deeper push toward real-world modular adoption — with blobstream, sovereign rollups, and DA-native builder tools in focus.
Expect more:
- Rollup frameworks using Celestia DA
- Real-time blob tracking tooling
- Community-led modular education
- Early product launches from Modular Day sessions
