Bitcoin’s Reasonable Hash RateHash rate refers to the number guesses an individual or network of machines can make at a hash each second. A hash is data converted into a string of text using a cryptographic algorithm. In the case of cryptocurrencies like Bitcoin, the hashes being guessed are of the transaction data stored in a block waiting to be added to the chain. If the miner successfully guesses the hash of the block, it adds the transactions to the chain and receives a reward in fees and from the network itself. Hash rate is important because it gives a measure of the amount of computing power enforcing the network’s rules. Providing the network is sufficiently distributed (no one actor controls too much of the hashrate), a higher hashrate generally means a more secure network. As evidenced in the above data from Blockchain.com, Bitcoin’s hashrate is currently well distributed. No single entity appears to control more than the mining pool BTC.com’s 18.9 percent. Multiple other pools control a considerable share of the total hashrate. Cryptocurrency analysis Twitter account @themooncarl describes the recent increases in hashrate as “almost parabolic,” adding that the network is growing in strength. security was no longer reliant on Chinese miners.
Hashrate is up nearly 6x since 2017 highs. We could lose all China miners tomorrow and bitcoin would be just fine. https://t.co/qh9c6QH8Dd— Mati Greenspan (tweets ≠ financial advice) (@MatiGreenspan) September 10, 2019
Better Bitcoin Mining HardwareOne reason behind Bitcoin’s new hashrate all-time high could be the recent launch more powerful mining hardware. The Antminer S17e and the Antminer T17e, two units from the mining hardware manufacturing giant Bitmain, launched simultaneously earlier this month. The firm claims that the S17e is capable of producing 64 TH/s and the T17e clocks 53 TH/s. This makes them the most powerful miners to date. Similarly, Ebang Communication just launched the EBIT E12+, itself capable of producing 50 TH/s.
However, cryptocurrency market analyst @hasufl provides a reality check to the bullish optimism surrounding Bitcoin’s higher hash rate. @hasufl states that if hash rate increases because of better technology, not increased numbers of miners themselves, it’s false to say that the network is more secure since any would-be attackers also have access to the same improved systems with which they could comprise the network.
Introducing the new #AntminerS17e & #AntminerT17e, 2 new miners that offer the best value for mining. The S17e has a 64 TH/s hash rate and 45 J/TH power efficiency, while the T17e has a 53 TH/s hash rate and 55 J/TH power efficiency.

What do you think about Bitcoin’s soaring hashrate? Do you think the price will follow its lead? Let us know below.
Two important caveats to that:— Hasu (@hasufl) September 11, 2019
1) hashrate is higher because the bitcoin price is higher – making Bitcoin a more attractive target to attack
2) hashrate is higher because there are better ASICs – that attackers also have access to https://t.co/pgfJbNhs3P
