Bitdeer unveils new energysaving chip for Bitcoin mining

Bitdeer, a Bitcoin mining company, has unveiled the “SEAL04” chip as part of its technological roadmap for the newly introduced Sealminer rig.
Scheduled for launch in the second quarter of 2025, the SEAL04 chip is expected to achieve remarkable energy efficiency of as low as 5 joules per terahash (J/TH).
The roadmap, as stated in a press release, aims to enhance transparency in mining by managing miners’ expectations regarding technological advancements and equipment delivery. It also provides data analytics on machine capabilities, inventory, and purchasing behavior.
Bitdeer is pioneering low-power Bitcoin mining with the introduction of the SEAL04 chip, which will power the fourth-generation Sealminer machine. Mass production and delivery of the machine are set to begin in the fourth quarter of 2025, with power consumption optimized to 5.5–6 J/TH, well below the industry average of 29 J/TH.
The rise in power consumption issues due to Bitcoin (BTC) mining has prompted mining companies to focus on reducing energy usage. Following the ban in Kazakhstan, miners have shifted towards greener grids in North America or sustainable off-grid locations.
The introduction of a more energy-efficient chip could signify a significant technological advancement in the cryptocurrency mining sector. This chip has the potential to improve Bitcoin mining performance while reducing power consumption, ultimately leading to lower operating costs and a smaller 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 play a vital role in cryptocurrency mining, as they are responsible for executing the complex computations needed to validate and secure transactions on the blockchain.
The news of the SEAL04 chip comes shortly after Tether signed a subscription agreement with Bitdeer to acquire up to $150 million worth of its shares in a private placement, according to an official announcement on May 31.
Tether CEO Paolo Ardoino praised Bitdeer as one of the leading vertically integrated operators in the Bitcoin mining industry, highlighting their advanced technologies and robust research and development efforts.
In May 2023, Bitdeer Technologies Group collaborated 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 further information on the SEAL04 chip but has not yet received a response.
