Foundry launches FB joint mining, with over 93% of BTC hash rate supporting Fractal Bitcoin
"This is not only an important moment for Fractal, but also a turning point for the Bitcoin community."The Bitcoin network's largest mining pool, Foundry USA, has launched merged mining for Bitcoin and Fractal Bitcoin on April 24. Foundry USA accounts for over 30% of the Bitcoin mainnet's hash rate, and its participation means that over 93% of the total Bitcoin hash rate is now simultaneously protecting the Fractal network, significantly enhancing its security.
Fractal Bitcoin has now become one of the safest Bitcoin-compatible networks. This not only boosts market confidence in the Fractal infrastructure but also signifies a broader shift—more experiments and application developments are gradually being built on the trusted foundation of Bitcoin. For Bitcoin miners, building around the Bitcoin mining ecosystem also captures additional economic benefits.
"This is not just an important moment for Fractal, but a turning point for the Bitcoin community," said Lorenzo, a core contributor to Fractal Bitcoin. "For years, developers have been forced to choose between the security of Bitcoin and development flexibility. The emergence of Fractal proves that this is actually a false dichotomy. With the participation of all major mining pools, Fractal benefits from the security and stability provided by the Bitcoin network infrastructure while continuously delivering innovation and flexibility for Bitcoin. Fractal is becoming a place where native builders are willing to invest—without having to change the Bitcoin protocol, but rather amplifying what it does best. We hope that as the network continues to develop, Fractal can help Bitcoin grow from a single blockchain into a scalable system that serves the real world with both stability and innovation."
The Cadence Mining mechanism used by Fractal is a hybrid mining model that combines network security protection with a dynamic revenue model for miners. One-third of the block rewards are generated through merged mining with Bitcoin, allowing existing Bitcoin miners to protect both networks without additional energy consumption. The remaining two-thirds of the blocks are produced through permissionless mining, enabling miners with more confidence in the Fractal network to seamlessly migrate Bitcoin hash power to expand their earnings, thereby complementing each other in the long run and enhancing the economic benefits of the Bitcoin ecosystem while protecting the Fractal network.

In addition to Foundry, other pools participating in Fractal's merged mining include Antpool, F2Pool, SpiderPool, and Binance Pool. According to data from the Fractal block explorer, the cumulative hash rate of the Fractal network has surpassed 770 EH/s.
"The widespread support from miners for Fractal reflects the growing confidence in Bitcoin-compatible infrastructure within the industry," said Spencer Yang, a core contributor to Fractal Bitcoin. "We firmly believe that innovation around Bitcoin does not mean changing its core, but rather expanding its application boundaries."
Fractal Bitcoin is built on the Bitcoin core codebase, expanding itself through Bitcoin itself. This will allow developers to natively build innovative applications and protocols within the Bitcoin ecosystem, gradually highlighting and deepening Fractal's role as an Innovation Layer in the Bitcoin ecosystem.
