When mining bitcoin , one of the key factors in determining success is the difficulty. As a Proof-of-Work-based cryptocurrency, crypto miners contribute hashpower in a race to solve complex puzzles required to secure each bitcoin block. Bitcoin mining difficulty is an indicator of how hard it will be to mine a BTC block. For individual miners or pools , a higher difficulty means more hashpower is needed to be in with a chance of gaining block rewards.

Bitcoin's difficulty last changed to At the most fundamental level, bitcoin difficulty varies depending on the computational power in the mining network. Difficulty functions to keep the block times fairly consistent, and so with a higher overall network hashrate, this difficulty will increase.

This difficulty shift is among the main criticisms of bitcoin's environmental impact. As the difficulty increases, more electricity is used in an attempt to solve the complex puzzles required for each block. Find and compare awesome blockchain and crypto products and services.

¿Qué es Bitcoin y cómo funciona? low difficulty bitcoins wiki


Hashing algorithms are used to create these random hash codes. Before new data can be added to a blockchain, miners must compete to produce a hash that's lower or equal to a numeric value called a target hash. Miners accomplish the hashing process by changing a single value, called a nonce —or a number used once—and each time the nonce is changed, a new hash is created with its own set of numbers.

There is no way of predicting what a hash will be and since each set of data has only one output for a given hash function, miners must repeat the process of adding a new nonce to the data until they meet the hash requirement. The requirement a hash must meet corresponds to the difficulty. A valid hash must be below a certain target value set automatically and periodically adjusted by the cryptocurrency's protocol.

The lower the target value, the more repetitions of the hash function a miner must go through in order to get an acceptable result—in other words, the higher the difficulty. A miner can, in theory, get lucky and obtain a valid hash for a given block on the first try.

However, over time, higher difficulty means that miners must plug through more nonces per block on average. Individuals and organizations contribute their computational power via their mining rigs to process the data and produce the hashes. The hash power of a cryptocurrency network represents the total hash rates of all the mining rigs. The hash rate is the number of hashes that can be calculated per second.

Since each hash is created randomly, it can take millions of guesses or hashes before the target hash requirement is met and new cryptocurrency coins are minted to the successful miner. Only then are the transactions added to a new block within the blockchain. In a way, the hashing process is similar to a lottery system. As a result, new coins are issued through this mining process.

The higher the hash rate, the more difficult it is for a fraudster to gain control of the blockchain since more hashing power is needed. In other words, the higher the difficulty, the more secure the network. One might wonder why a network's participants would establish a higher cryptocurrency difficulty if the result meant miners repeating the same function over and over. There are two key benefits to cryptocurrency difficulty.

The bitcoin whitepaper by Satoshi Nakamoto explains how the proof-of-work difficulty helps to generate a steady production of new blocks added to the blockchain. Bitcoin is designed to add a new block to the blockchain every 10 minutes on average.

Other cryptocurrencies aim for more frequent blocks; litecoin , for example, aims for 2. The issue is that the amount of computing power the network's miners collectively control can vary enormously. When Satoshi Nakamoto mined the first block, there was only one machine on the network—likely a simple laptop or desktop. Today there are a number of sprawling, warehouse-sized ASIC farms. ASICs are machines designed specifically to plow through hash functions as fast as possible.

In order to ensure that the network produces a new block at a steady average rate, the software is set to automatically adjust the target hash up or down, which results in lower or higher difficulty, respectively. When Nakamoto mined the genesis block, bitcoin's difficulty was one. The overall hash rate provides insight into a cryptocurrency network's security since fraudsters or bad actors would need to overcome the total hash power of the network to take control in a malicious attack.

Specially designed computers are used to perform hashing functions, which are able to make trillions of guesses each second to solve the hashing problem. The higher the cryptocurrency difficulty, the more guesses or hashes are needed to reach the target hash requirement.
