Two Mining Pools to Gain 50% of the BCH Hashrate

Media reports that Coingeek and BMG Pool are affilated with odious Australian entrepreneur Craig Wright

The centralization of Bitcoin Cash mining has reached a new level after only two pools - Coingeek and BMG Pool - have established control over more than 50% of the total network hash. This is reported by Trustnodes.

Earlier today, there were also reports that at some points the aggregate capacity of both pools reached 58%.

While BMG Pool directly belongs to the odious Australian entrepreneur Craig Wright, the no less scandalous Calvin Ayre, who maintains close ties with Wright, is considered the nominal owner of Coingeek.

The current situation, the media believes, does not exclude the possibility of collusion of the 51% attack on the network. In particular, in this case there is a probability of double spend of coins, which, accordingly, will force the exchange to increase the number of required transaction confirmations.

At the same time, the current situation is likely to be a demonstration of power by Craig Wright on the eve of the November upgrade of the network. As a result of disagreements between different groups of developers, it is still possible that Bitcoin Cash, which at one time split from bitcoin, will itself be split into two separate chains.

Note that the Bitcoin Cash hashrate on the whole continues to remain at a fairly low level, accounting for less than 8% of the bitcoin.

Sapphire Technology has announced plans to release a new Radeon RX 570 Nitro + video card, equipped with 16 GB of GDDR5 memory. As reported by TechPowerApp, it is designed for Grin cryptocurrency mining.

Grin is based on the MimbleWimble protocol and the Cuckoo Cycle PoW hashing algorithm, which can load up to 11 GB of video memory, which explains the non-standard characteristics of the new graphics card.

The video card is made in the traditional Nitro + design with a dual-fan cooler and uses sixteen GDDR5 memory chips.

The cost of the Radeon RX 570 Nitro + has not yet been named, but Sapphire promises that it will be sold at the price of "one third of the cost of competing cards at 16 GB."

Aday after the launch of the main cryptocurrency network, Grin is mined by at least 88,000 graphics processors. Grin hash rate is 285.6K graphs / s.

In June 2017, Sapphire introduced a line of Mining Edition boards of five models, made on the basis of Sapphire Radeon RX 470 and Sapphire Radeon RX 560. The memory capacity of video cards ranged from 4 to 8 GB.
