This week, in Bitcoin’s hashrate Hitbeast mode, the network bent a record smash of 1,109 exahash (EH/S) as it made the computational biceps stiffer than ever before. Meanwhile, Bitcoin hashrate fireworks also illuminate merged neighbors as lecherous coins, rootstocks and fractal bitcoins all get monster boosts on rockets.
Merge Mining unlocks over 700 EH/S power plays
Thanks to merge mining (AKA Auxiliary Proof-of-Work (AUXPOW)), Bitcoin hashrate is not a one-trick pony. Minors can bend the same computational grind to lock down multiple chains at once, converting application-specific integrated circuit (ASIC) rigs into multitasking machines.
Recently, Bitcoin has been officially trampled on Zettahash (Zh/s) in the ERA, where today’s miners collectively pump 1,000 EH/s. The tide waves of hash power don’t just inflate Bitcoin. I also juiced the name coins, rootstocks and fractal bitcoins.
We take Namecoin, an OG Altcoin born in 2011. I’ve been riding a shotgun with Bitcoin in Marge Mining and have been around for many years. He is currently bent at 732 EH/s, and last week at Block 791037 he cranked out an all-time high of 786.98 EH/s. Clocking to 786.98 eh/s, the peak hash of the namecoin is more than just a blip. It outweighs the strength of some combinations of today’s Top Proof of Work (POW) networks.
LOTSTOCK (RSK) hashrate at 9:25am on September 29th, 2025 at 9:25am in the East.
Rootstock, a bitcoin sidechain built for smart contracts with RBTC tokens pinned to BTC, is another big winner of Bitcoin’s towering hashrate. Using merge mining, leveraging Bitcoin security, Miners pockets RSK trading fees along with BTC rewards. Currently, the rootstock has recorded approximately 822.92 eh/s.
In other words, Namecoin rides around 69.3% of Bitcoin’s current 1,057 EH/s, while the rootstock is trapping solid hash power handmines from the big chain in solids. Fractal Bitcoin (FB) also draws 768.91 EH/s from Bitcoin overflow, not leaning forward.
FB runs in a hybrid setup. Merges are mined together with Bitcoin, but are mined on their own. It aims to stack recursive layers framed as a Bitcoin scaling solution and built from Bitcoin core code, increasing the reach of the chain without breaking the base.
Overall, Bitcoin’s march into the Zettahash era does not only bending its own superiority. It lifts up several ecosystems afterwards. Merge mining is more proven than a technical footnote, as some networks suck up a large portion of its hashrate. This is a full-scale multiplier of security and scale across multiple POW networks.
