Bitcoin Cash Network hardfork implemented

Own Bitcoin Cash hardfork will not release new tokens; it is aimed to provide a new complexity recalculation algorithm
14 November 2017   2011

The Bitcoin Cash hardfork was held, as planned, on Monday, November 13, at block 504031, however, this event occurred a few hours after the previously announced time.

This fork is aimed at improving the existing complexity algorithm and assumes, among other things, a predictable time for confirming transactions on the network. According to the idea of ​​the developers, this parameter will be 10 minutes.

In addition, new features should help to avoid sudden changes in complexity with a relatively stable hash and perform a quick recalculation of the complexity with its rapid change. It is also expected that after the fork, the Bcash network will become resistant to certain attacks, for example, by manipulating timestamps.

It should be noted that by the moment of fork the profitability of BTC mining was 3 times higher than the similar indicator of BCH. This index is calculated on the basis of such factors as the amount of commissions, the market rate and the complexity of mining. At the moment of press this index reduced to 1.26.

On the eve of today's event, the price of Bitcoin Cash, having demonstrated unparalleled growth over the weekend, updated the historic high ($ 2477.65 on Coinmarketcap).

This was followed by an equally impressive fall: at some point on Monday the price of the coin fell to $ 1043. By the time of the fork, the BCH rate had risen to $ 1,436. At the moment of press, average BCH price is $1254.69.

Bitmain to Announce New ASIC Chip

BM1397 chip requires less energy and is able to achieve efficiency at 30J / TH
18 February 2019   99

This Monday, the Chinese mining company Bitmain announced the next-generation 7-nm chip codenamed BM1397, which, according to it surpasses its predecessors in performance and energy efficiency and is suitable for mining cryptocurrencies on the SHA256 algorithm, including Bitcoin and Bitcoin Cash.

The BM1397 chip requires less energy and is able to achieve efficiency at 30J / TH, which is “higher by 28.6% than the previous 7-nm chip from Bitmain”, codenamed BM1391.

BM1397 is manufactured using TSMC, a Taiwan-based semiconductor product company, which is one of the leading suppliers in the cryptocurrency mining industry.

The BM1397 chip will be installed in the new ASIC miners of the Antminer S17 and Antminer T17 models, the release of which Bitmain promises to announce later. The company does not provide other details of the updated devices in its message.
