Mga FAQs ng Hashrate

Ano ang Kasalukuyang Hashrate ng Bitcoin？

171 million EH/s, which stands for exa hashes per second, at the time this article was published. 1 exa hash = 1 quintillion hashes.

That means that miners are computing 171 quintillion hashes every second. Find the most current estimate at Blockchain.com.

Bakit Mahalaga ang Hashrate？

Higher hashrate means more resources are being devoted to process transactions on the blockchain. This makes a network more resilient to attacks because a malicious agent would need to spend vast sums of money to outcompete other mining facilities in order to gain a 51% majority control and stop other peoples transactions, or double-spend their own coins.

It follows, then, that the higher the hashrate, the harder it is for a bad actor to source the necessary hashing power and, as such, the harder the network is to attack.

Ano ang Kahirapan sa Pagmimina？

Mining “difficulty” is how difficult it is for miners to produce a hash thats below the target hash.

In Bitcoin, the difficulty automatically adjusts every 2,016 blocks. Blocks are targeted to be found by miners every 10 minutes. So if miners are finding bitcoins more often than every 10 minutes on average, the difficulty moves upward. If miners are finding bitcoins less often than every 10 minutes on average, the difficulty moves down. With Ethereum, mining complexity uses a similar system to Bitcoin with the added addition of a “difficulty bomb” that was introduced back in 2015 and went live during the Homestead update in early 2016. This increases the time it takes to mine each new block with the aim of phasing out ether mining to make way for the new Proof-of-Stake (POS) mechanism in the 2.0 upgrade.

Difficulty is a key piece of calculating a hashrate. The more difficult it is to mine, the more hashes will need to be generated to find the block rewards, pushing the total hashrate higher.

Paano Kinakalkula ang Hashrate？

Theres no way to know for sure the exact hashrate of a mineable cryptocurrency, though it can be estimated. Hashrate is traditionally estimated based on public data about the underlying cryptocurrency, including the difficulty metric described above.

Though this traditional estimation method is in the right ballpark, this methodology has long been criticized as not precisely accurate. The Kraken crypto exchange proposed another way of estimating the hash rate, using statistics to show with 95% confidence that the hashrate lies in some range.

Bakit Napunta sa Wala ang Hashrate ng Bitcoin？

More and more miners have entered the fray in Bitcoins short history, pushing the hashrate up.

The most likely reason for new miners joining the highly competitive space is because of bitcoins high price potential. An increase in demand for bitcoin (which is a scarce asset) recently pushed the price above $40,000 per coin (it is lower now, at press time), which in turn has attracted more operators who are seeking to get in on these significant returns.

Any rise in miners pushes Bitcoins difficulty up, which then drives the hashrate up.
