Bitdeer unveils new environmentally friendly chip for Bitcoin mining

Bitdeer, a Bitcoin mining company, has unveiled the cutting-edge “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 anticipated to achieve remarkable energy efficiency of as little as 5 joules per terahash (J/TH).
The roadmap, as per a press release, is designed to enhance transparency in mining, manage miners’ expectations regarding technological advancements and equipment delivery, while also offering data analytics on machine capabilities, inventory, and purchasing patterns.
Revolutionizing low-power Bitcoin mining
Bitdeer has disclosed that the SEAL04 chip will power the fourth-generation Sealminer machine, which is set to be mass-produced and distributed starting in the fourth quarter of 2025. The machine’s power consumption is projected to be optimized to 5.5–6 J/TH, significantly lower than the current average of 29 J/TH.
Bitcoin mining has faced challenges in terms of power consumption, prompting mining companies to focus on reducing energy usage. Following its ban in Kazakhstan, miners have shifted primarily to eco-friendly grids in North America or sustainable off-grid locations.
The introduction of a more energy-efficient chip could represent a major technological breakthrough in the cryptocurrency mining sector.
This chip has the potential to provide enhanced Bitcoin mining performance with reduced power consumption, resulting in lower operational costs and a smaller environmental impact for miners.
Prior chip advancements
In March, Bitdeer revealed the successful initial testing of the SEAL01 chip, a 4-nanometer Bitcoin mining chip with a power efficiency of 18.1 J/TH. It was utilized in the Sealminer A1 mining rig.
The SEAL01 chip was developed using a semiconductor fabricator’s 4-nanometer process technology. Bitdeer claimed that the chip could achieve a power efficiency ratio of 18.1 J/TH.
Chips play a critical role in cryptocurrency mining, as they are responsible for executing the complex computations necessary to validate and secure transactions on the blockchain.
In a related development, Tether recently entered into 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.
According to Tether CEO Paolo Ardoino, Bitdeer stands out as one of the most formidable vertically integrated operators in the Bitcoin mining industry, thanks to its advanced technologies and robust research and development initiatives.
In May 2023, Bitdeer Technologies Group collaborated with Bhutan’s sovereign investment arm, Druk Holding and Investments (DHI), to establish environmentally friendly and carbon-neutral digital asset mining operations in Bhutan.
Cointelegraph reached out to Bitdeer for further details on the SEAL04 chip but has not yet received a response.
