Bitmain’s Unrelenting Innovation in Mining

Bitmain, a mining industry frontrunner, continues to release ground-breaking miners, extending its market dominance. The Antminer T21, unveiled at the Blockchain Life 2023 Forum, is the latest addition to the company’s extensive product lineup, featuring air-cooling technology appropriate for high-temperature operations. Antminer T21, which will be available in January 2024, has a phenomenal computing capacity of 190 terahashes per second and supports the SHA256 mining algorithm, which is essential for Bitcoin and its derivatives.

The Antminer T21 is the latest in a string of Bitmain releases, following the introduction of two new S21 series devices last month. The Antminer S21 Hydro miner can accomplish up to 335 TH/s with an efficiency rating of 16 J/T, whereas the air-cooled S21 miner can achieve up to 200 TH/s with an efficiency rating of around 17.5 J/T.

While the Antminer S21 air-cooled machine has slightly higher ratings than the T21, the latter outperforms the S19 Antminers in efficiency ratios. The T21 has a power consumption of 3,610 watts and is scheduled to ship in the first quarter of 2024.

Beyond Conventional Mining

Bitmain’s thirst for diversification has been demonstrated by the release of the rack-style AntRack miner, which features a modularized, hot-swappable design perfect for large-scale operations without downtime during updates 3. Bitmain is adding another feather to its cap by launching privacy-focused blockchain mining miners for Aleo, a blockchain platform that uses zero-knowledge proofs 4.

Customer-Centric Initiatives

With the debut of Antminer T21 comes Bitmain’s price protection plan, which protects owners from any BTC price drops.  The Protection Plan, which is available until November 25, 2023, will protect consumers against the price volatility of Bitcoin for one, three, or six months. This unique action demonstrates Bitmain’s dedication to providing a safety net for its customers in the midst of the cryptocurrency market’s inherent volatility.
