Introduction
Fractal Bitcoin, a Layer 2 scaling solution for the Bitcoin network, has reached a significant milestone by securing 93% of Bitcoin’s total hashrate. This achievement enhances the network’s security and demonstrates the growing adoption of Fractal’s innovative approach to Bitcoin scalability.
Foundry Joins Fractal Bitcoin
On April 24, 2025, Foundry, one of the largest Bitcoin mining pools, began merged mining with Fractal Bitcoin. This collaboration has propelled Fractal’s merged mining hashrate to over 719 EH/s, accounting for 93% of Bitcoin’s total hashrate. The integration signifies a strong endorsement of Fractal’s Cadence Mining model and its potential to revolutionize Bitcoin mining.
Understanding Cadence Mining
Fractal’s Cadence Mining is a novel approach that combines permissionless mining with merged mining. In this system, two-thirds of the blocks are mined independently on Fractal, while one-third are merged-mined with Bitcoin. This structure ensures robust security and incentivizes participation from various mining pools.
Benefits for Miners
By participating in Fractal’s merged mining, miners can increase their profitability without investing in new hardware. The dual-mining capability allows for additional revenue streams, making it an attractive option for mining operations seeking to maximize returns in the post-halving environment.
Optimizing Antminers with Vnish Firmware
To further enhance mining efficiency, miners can utilize the Vnish official firmware for their Antminer devices. This firmware supports overclocking for various models, including:
- Antminer S21/T21: Overclocking up to 300 TH/s
- Antminer S19 series: Overclocking up to 200 TH/s
- Antminer L7 series: Enhanced performance and efficiency
Implementing this firmware can increase profitability of Antminers by 25% and reduce power consumption by 15%, offering a cost-effective solution for miners aiming to optimize their operations.
Conclusion
Fractal Bitcoin’s achievement in securing 93% of Bitcoin’s hashrate marks a pivotal moment in the evolution of Bitcoin scalability solutions. The integration of major mining pools like Foundry underscores the industry’s confidence in Fractal’s approach. Coupled with optimization tools like Vnish firmware, miners are well-positioned to capitalize on these advancements for enhanced profitability and efficiency.
