Zcash (ZEC) Blossom Upgrade To Improve Speed, Scalability and Capacity

11, Dec 2019

Zcash Blossom is the next major network upgrade of Zcash (ZEC) scheduled to activate today at block height 653600 in a couple of hours. This mandatory network upgrade is designed to improve the network scalability and user experience by cutting block times in half (to about 75 seconds), making transaction confirmations faster, doubling network throughput and keeping transaction fees low. To keep the ZEC coin emission rate and halvening schedule of Zcash unchanged, the halved block times also require that the per-block reward be halved as well. The emission rate per time, however, remains unchanged. Other values based on block intervals will also be updated accordingly, such as end-of-service halt, default transaction expiry, and the number of confirmations required to consider a transaction final.

New Innosilicon Equihash A9++ ZMaster ASIC Miner

22, Mar 2019

It seems that not only Bitmain it getting back in the game with a more powerful Equihash ASIC miner, but Innosilicon also has a new offer for such device. The new Innosilicon Equihash A9++ ZMaster is the successor of their original A9 Zmaster ASIC from last year that offered 50 Ksol/s hashrate for Equihash. The new Innosilicon Equihash A9++ ZMaster comes with 140 Ksol/s hashrate at 1550W of power usage, so efficiency wise it does not seem much better than the original A9 Zmaster – it is almost 3 times faster at almost 3 times the power usage. Innosilicon listed briefly Innosilicon Equihash A9+ ZMaster (with just one plus) with 120 Ksol/s at the same 1550W, but it is not available anymore.

The Innosilicon Equihash A9++ ZMaster is available for order at a price of $1580 USD (without a power supply). It is very similar specifications wise to what Bitmain is offering with their AntMiner Z11, however the A9++ ZMaster could ship faster and be in your hands a bit early. The problem is that unlike Bitmain that caught up with their new product, Innosilicon seems to have just put more of the chips into a bigger device as they were ahead of Bitmain specs wise already with their A9.

Innosilicon Equihash A9++ ZMaster Specifications:
– Hashrate: 140Ksol/s +/-6%
– Power Consumption: 1550W +/-10% (normal mode, at the wall, with 93% efficiency PSU. 25°C temperature)
– Dimensions: 360mm(L)*250mm(W)*155mm(H), dual tube
– Net Weight: 11KG
– Ambient Temperature: 0°C to 40°C
– Network Connection: Ethernet

Bitmain Antminer Z11, a New More Powerful Equihash ASIC Miner

19, Mar 2019

The new Bitmain Antminer Z11 ASIC offers a hashing power of 135 KSol/s for the Equihash algorithm used by ZCash (ZEC) and other crypto currencies and is essentially the successor of the Antminer Z9 from the last year that offered 40 KSol/s and the Antminer Z9 mini that was just 10 KSol/s. The Antminer Z11 uses Bitmain’s latest proprietary 12nm chip, which is made using advanced Bare Die molding technology for better heat dissipation and has a power-efficiency of 10.50 J/KSol, so it is with significant improvement over the older hardware. The recommended power supply for this miner is 1800W, though the actual like the APW7 PSU from Bitmain, though the actual power consumption is lower (1418 W power consumption claimed). The current price of the Antminer Z11 is $1242 USD and shipping should start around the end of April (20-30).

Bitmain Antminer Z11 Specifications:
– Model No.: 240-Z
– Crypto Algorithm/Coins: EquiHash/Zcash
– Hashrate, KSol/s: 135
– Reference power on wall, Watt: 1418
– Reference power efficiency on wall @25°C, J/Ksol: 10.50
– Adapted AC/DC output requirement, Watt/ Volt: 1729/ 12.00
– Quantity of hash chips: 9
– Quantity of hash boards: 3
– Networking connection mode: RJ45 ethernet 10/100M
– Miner Size (Length*Width*Height, w/o package), mm: 242*134*302
– Net weight, kg: 5.40
– Noise, dBA @ 25°C: 70
