Bitcoin mining company Bitdeer Technologies has showcased the SEAL04 chip in its technology roadmap for the newly launched SEALMINER rig.

Set for release in Q2 2025, the SEAL04 chip is projected to achieve energy efficiency as low as 5J/TH (joules per terahash).

According to a news release, the roadmap aims to boost transparency in mining, managing miners’ expectations for tech advancements and equipment delivery while providing data analytics on machine capabilities, inventory, and purchasing behavior.

Pioneering low-power Bitcoin mining

Bitdeer stated that the SEAL04 chip will power the fourth-gen SEALMINER machine, which will be mass-produced and delivered starting Q4 2025. The machine’s power consumption will be optimized to 5.5-6J/TH, below the average 29J/TH.

Bitcoin (BTC) mining created a problem of power consumption. So mining companies have since increased efforts to ensure that the process consumes less power. After its prohibition in Kazakhstan, miners predominantly moved to greener grids in North America or sustainable off-grid sites.

Introducing a chip with such energy efficiency could mark a significant technological advancement in the cryptocurrency mining industry.

This chip will offer a much more enhanced Bitcoin mining performance with minimized power consumption, leading to lower operating costs and a reduced environmental footprint for miners.

Previous chip developments

In March, Bitdeer announced the successful initial testing of SEAL01, a 4-nanometer Bitcoin mining chip with a power efficiency of 18.1 joules per terahash. It was used in its Sealminer A1 mining rig.

The earlier SEAL01 was designed using a semiconductor fabricator’s 4-nanometer process technology. The company claimed the chip could achieve a power efficiency ratio of 18.1 J/TH.

Chips play a crucial role in cryptocurrency mining, as they are the hardware components responsible for performing the complex computations required to validate and secure transactions on the blockchain.

The news comes a week after Tether entered into a subscription agreement with Bitdeer to purchase 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 is one of the strongest vertically integrated operators in the Bitcoin mining industry due to its cutting-edge technologies and robust research and development efforts.

In May 2023, Bitdeer Technologies Group and Bhutan’s sovereign investment arm, Druk Holding and Investments (DHI), teamed up to create eco-friendly and carbon-free digital asset mining operations in the Kingdom of Bhutan.

Cointelegraph contacted Bitdeer for more information on the SEAL04 chip but has yet to receive a response.
