Bitmain Asic Miner Antminer Z15 420K In Stock Blockchain Mining Machine Second Hand ZEC Miner
Introduction
Why is z15 the price performance king of Zec
Why is this machine called the king of cost performance? First of
all, the machine itself is a limited product, which is divided into
four batches around the world, with a total of 800 sets in each
batch, so it is very valuable. Secondly, the machine process is
made of 7Nm chip, which is the most advanced technology at present.
Finally, let's look at the power consumption and computing power
ratio of the machine. Z11, the best machine in the market, has a
computing power of 135k and a power consumption of 1400W; The
computing power of ant z15 is 420k, and the power consumption of G
is 1510; The computing power is more than three times that of Z11,
but the power consumption is not much different. Many people are
considering whether halving in November will affect the price of
machines

Specification
Bitmain officially launched the ant miner z15 at 2 p.m.
Beijing time on May 7. This is a brand-new ant miner for mining
anonymous Zec coins. It is also the Zec miner with the highest
computing power at present.
According to official data, the computing power of the new z15 is
420ksol / s and the power consumption is 1510w. It is equipped with
9 chips and weighs 10kg.
Zcash, also known as big change coin, is one of the three
mainstream anonymous coins on the market (big change coin, Monroe
coin and Dasi coin). Zec will halve in November 2020, which is also
the mainstream currency to halve at the latest this year. At
present, the mining machines digging Zec in the market are mainly
ant mining machine Z11 and core A9 series.
Ant miner Z11 is a miner released by bitcontinental in March last
year. Its computing power is 135k sol / s, which is only one third
of the z15 miner on sale. Xindong A9 is a small mining machine
launched by Xindong technology in 2018. Its computing power is only
50ksol / s ± 6%, less than one eighth of that of z15 mining
machine.
Ant miner z15 is the third generation of miner based on equihash algorithm in bitland. In August 2018, the first generation of equihash algorithm miner Z9 was launched, z9mini was launched at the same time, and the second generation Z11 was launched in April 2019. Later, z11e and z11j were launched. Equihash algorithm is mainly used for mining by Zec (zcash) and its currency using equihash algorith
Zec (zcash), whose Chinese name is big zero coin, is a digital currency based on zero knowledge proof. Zec (zcash) was developed on the basis of the original bitcoin code base and released on October 28, 2016. On the premise of protecting privacy, Zec users can decide to disclose some information, such as choosing to hide the receiving address, transaction information or balance. Zec can realize economic benefits and transfer money quickly and reliably. Before Zec (zcash) is released, The scarcity of Zec caused the price to soar. It reached 10 BTC (about US $6864) on the day of official launch. On October 28, the futures price on poloniex reached 1 Zec to exchange 3300 BTC (more than US $2 million). However, the price fell sharply after that, and the price after that day was 48 BTC / Zec (data source: Babbitt). The quotation on June 1, 2020 is 0.0055 BTC / Zec (about US $53).
Ant miner z15_ 420k needs external power supply, while bit continental distributes apw7 power supply when it is sold, so it will receive two independent packages when it arrives. The main machine of the mining machine is packaged in industrial cartons, which are printed with manufacturer information, logistics and storage identification, packaging size and other information. The appearance size is 331x234x390mm and the weight is 6.4kg.
After removing all the packages, it can be seen that the ant miner z15_ 420k is similar to the previous generation Z11. Due to the need for external power supply, the bare metal machine has a simple and capable body, with a physical size of 240x136x290mm and a total weight of 5.9kg.
Ant miner z15_ 420k adopts the design of parallel double fan single exhaust air supply and heat dissipation. The mining machine can be placed upright and lying on its back according to the mine frame. However, according to the size, the frame with 25cm floor height in the mine can only be placed on its back.
Ant miner z15_ The 420k protective cover is of snap on design and fastened with screws to prevent inadvertent opening of the protective cover. Remove the screws of the protective cover, press and hold the button and push it up to open it. This step is also required when connecting the power line.
Ant miner z15_ The 420k control board and the force calculation board are connected by flat cable, and the power interface on the force calculation board is 6pin interface.
Remove the connecting wire on the control board and remove the baffle screw in front of the control board to pull out the control board from the interface side. Ant miner z15_ 420k uses a newly designed control board, the model is Ctrl_ C55.
The interface of the control board shall be consistent: SD card TF card slot, which is used to brush the firmware of the card; IP report - IP Report button, which is used to cooperate with ant tool to find the IP address of mining machine; Eth network cable interface; Reset - restart button (press and hold to restore the factory setting); LED status indicator - displays the operation status of the miner.
