Foundry Begins Merged Mining Fractal — Strengthening Bitcoin’s Innovation Layer

With Foundry now merged mining Fractal, Fractal’s security has now pushed further to new heights, with over 93% of Bitcoin’s global hashrate now securing our network. It’s a powerful signal that Fractal’s mission to scale Bitcoin without compromise continues to involve major players in the Bitcoin mining ecosystem.

Why This Matters

🔐 Strengthens Network Security & Decentralization

Foundry’s hashrate significantly boosts Fractal’s merged mining hashrate with our Cadence Mining model, bringing the hashrate to over 719 exahashes per second (EH/s). Fractal is now one of the most secure Bitcoin-aligned networks, with 93% of Bitcoin’s hashrate merged mining it.

⚙️ Powering Native Bitcoin Innovation

Fractal doesn’t change Bitcoin — it amplifies it. With Cadence Mining, Fractal enables new apps and protocols to flourish on a Bitcoin-secured foundation, combining the best of Proof-of-Work with innovation and speed.

Fractal’s Cadence Mining

Fractal’s innovative Cadence Mining structure is fully compatible with Bitcoin.

• One-third merged mining with Bitcoin

  • Leveraging existing Bitcoin mining operations and security with mining pools such as Foundry

• Two-third permissionless mining

  • Opening participation to a broader range of miners

  • Ensures aligned economic incentives to secure Fractal network itself

This milestone is just the beginning. As more mining pools recognize the value of merged mining Fractal, we continue to strengthen Bitcoin's ecosystem by providing miners with an additional revenue stream that requires no extra hardware or energy expenditure.

With major mining pools like Foundry contributing to the network security — joining other major pools such as Antpool, f2pool, ViaBTC, Binance Pool, and more — it's becoming clear: Fractal is a growing home for Bitcoin-native innovation. It's the innovation layer where Bitcoin's potential can be explored and expanded while maintaining its core principles.
