The hashrate for the Bitcoin network has made a remarkable recovery since it crashed following Communist china's crypto mining clampdown before this twelvemonth.

The Bitcoin hashrate has now topped 150 Exahashes, or one quintillion hashes, per second according to data from analytics provider CryptoQuant.

On Aug. 24, the metrics provider reported a hashrate of 152 EH/s which has tripled since it bottomed out this year on June 28 at 52 EH/s.

The recovery of the BTC hashrate means that the network is much more secure and harder to attack.

The boilerplate Bitcoin hashrate — the amount of calculating power in the network — striking an all-time high of 197.6 EH/s on May thirteen according to Bitinfocharts. Over the six weeks or so that followed, it slumped by more than 65% every bit mining rigs across People's republic of china were powered down for the "great miner migration".

The metric is at present approaching early June levels and, if the tendency continues, could hitting a new best high within the next couple of months.

In early on May, Cointelegraph reported that there was already evidence that hashrate was moving away from China. Details on the migration are difficult to come past: Cambridge University's well-sourced "mining map" has non been updated since April when information technology reported 65% of the hashrate residing in China.

Measuring hashrate information by mining pool is also inaccurate since many pools are a mix of hash power from physical facilities and miners from all around the earth pooling computing resource.

Since the hashrate has now recovered, it would indicate that the miner migration is almost consummate. This has resulted in an increase in difficulty, with the last rise of around 7% occurring on Aug. xiii. The next 1 is due whatever time now, which will mean higher computational costs for miners every bit more of the formerly Prc-based operations come back online to compete for blocks. The current gauge is for a 12.37% difficulty increment.

While the migrating operations were offline in June and July, miners already operating in countries such as the United States were able to rake in bigger profits due to the lower difficulty.

This calendar week, Cointelegraph reported that U.S. mining firm Riot Blockchain announced record revenue for BTC mining during the second quarter.
