Bitdeer unveils new energysaving chip for Bitcoin mining

Bitdeer, a Bitcoin mining company, has unveiled the “SEAL04” chip as part of its technology roadmap for the newly introduced Sealminer rig.
Expected to be launched in the second quarter of 2025, the SEAL04 chip is projected to achieve an energy efficiency of as low as 5 joules per terahash (J/TH).
In a press release, the roadmap aims to enhance transparency in mining, manage miners’ expectations regarding technological advancements and equipment delivery, while also providing data analytics on machine capabilities, inventory, and purchasing behavior.
Bitdeer stated that the SEAL04 chip will power the fourth-generation Sealminer machine, which will be mass-produced and delivered starting in the fourth quarter of 2025. The machine’s power consumption will be optimized to 5.5–6 J/TH, below the industry average of 29 J/TH.
Bitcoin mining has faced challenges related to power consumption, prompting mining companies to focus on reducing energy usage. Following its ban in Kazakhstan, miners have largely transitioned to greener grids in North America or sustainable off-grid locations.
The introduction of a more energy-efficient chip could represent a significant technological advancement in the cryptocurrency mining sector. This chip has the potential to enhance Bitcoin mining performance while minimizing power consumption, thereby reducing operating costs and environmental impact for miners.
In March, Bitdeer announced the successful initial testing of the SEAL01 chip, a 4-nanometer Bitcoin mining chip with a power efficiency of 18.1 J/TH. This chip was utilized in the Sealminer A1 mining rig.
Chips are vital components in cryptocurrency mining, responsible for carrying out the complex computations necessary to validate and secure transactions on the blockchain.
Recently, Tether signed a subscription agreement with Bitdeer to acquire up to $150 million worth of its shares in a private placement, as announced on May 31. Tether CEO Paolo Ardoino praised Bitdeer as one of the leading vertically integrated operators in the Bitcoin mining industry due to its cutting-edge technologies and strong research and development efforts.
In May 2023, Bitdeer Technologies Group joined forces with Bhutan’s sovereign investment arm, Druk Holding and Investments (DHI), to establish eco-friendly and carbon-free digital asset mining operations in Bhutan.
Cointelegraph reached out to Bitdeer for additional information on the SEAL04 chip but has not yet received a response.
