Bitmain, the world’s largest cryptocurrency mining hardware manufacturer, has unveiled a new version of Antminer Z series on March 19 for mining Equihash algorithm-based cryptocurrencies such as the privacy-focused Zcash, according to a blog post released by Bitmain.

The new device dubbed Antminer Z11 is an ASIC (application-specific integrated circuit) miner which is said to be the most powerful Equihash miner so far. It is capable of offering a hashing power of 135 K Sol/s( solutions per second), which is three times more powerful than that of the Antminer Z9, Bitmain’s previous Equihash miner that was launched in last May.

Bitmain adds that with a newly-designed internal circuit structure, the Antminer Z11 is more energy-efficient with a power efficiency of 10.5J/K, saving 60 percent of electricity costs compared to that of its predecessor. Further,the 12nm chip-equipped Antminer Z11 delivers a better heat dissipation performance than the Z9.

The new device which is priced at $1336 has been on the pre-sale since Tuesday and the shipping is expected to start around the end of April (between 20th and 30th). However, the allocated number of units available for the first batch were said to be sold out within 20 minutes, according to a crypto miner. At he time of writing, however, the Antminer Z11 is available for purchase on Bitmain’s official website.

The new miner is launched at a time when a debate is heating up in the Zcash community over whether to make the network ASIC-resistant. Because of the ASIC miners leading to centralized mining, Bitmain has been long accused of boasting an unfair advantage in the ASIC mining and trying to centralize hash power of cryptocurrencies such as Zcash. In order to allay worries from the community, the Beijing-headquartered mining giant promises to offer more transparency to Zcash miners.

“To preserve the Zcash community’s values around security, reliability and accessibility, Bitmain had previously Tweeted real-time updates to ensure more transparency and will continue to provide shipping updates of the first batch of the Antminer Z11,” Bitmain said in the blog post.

Following the good news, Zcash price surges to $60.11 at the press time, up 7.52 over the last 24 hours, according to data from coinmarketcap.

The release of the Antminer Z11 comes a month after the formal debut of Bitmain’s next-generation 7nm ASIC chip called BM 1397, which is designed to mine proof-of-work(PoW) cryptos based on the SHA256 algorithm, such as bitcoin (BTC) and bitcoin cash (BCH). The BM1397 delivers breakthrough energy efficiency.

In addition, Bitmain will continue to forge ahead with new products and plans to launch its three most advanced miners under the SHA256 algorithm—Antminer S17 Pro, Antminer S17, and Antminer T17—in the near future.
