BCH can be used for peer-to-peer payments and value storage within the Bitcoin Cash network. With its larger block sizes relative to Bitcoin , Bitcoin Cash aims to offer high throughout and on-chain scalability through increased block sizes, aiming to reduce the reliance on off-chain scalability solutions for transactions.
Bitcoin Cash, the protocol, is a distributed, time-stamped ledger of unspent transaction output UTXO transfers stored in an append-only chain of 32MB data blocks. A network of mining and economic nodes maintains this blockchain by validating, propagating, and competing to include pending transactions mempool in new blocks. As such, it went through two halvings to date; in November , and again in July , each cutting the initial block reward by half.
On average, Bitcoin Cash generates new blocks every 10 minutes, rewarding miners with Each block has a 32MB limit and block rewards are halved every , blocks approximately 4 years. Eventually, once the 21 million BCH hard cap has been reached, block rewards will transition entirely to transaction fees shifting the security model of the protocol to one based on demand for block space versus one based on demand for BCH. Consensus Bitcoin Cash uses Nakamoto Consensus whereby the valid chain is the longest chain with the most accumulated proof-of-work.
Consensus in Bitcoin Cash, and other systems using Nakamoto Conensus, is probabilistic because there is always a chance that a new, longer competing chain could emerge with more accumulated proof-of-work, that would invalidate the current chain. Mining Miners solve computational puzzles to generate new blocks using a SHA algorithm.
Typically, the block reward is halved and leads to a decrease in cryptocurrency emission, which can positively affect the growth of its value.

It essentially came down to block size. On one side, Roger Ver and the company wanted to keep the block size of 8MB. On the other end, there was Craig Steven Wright and company, who wanted to increase the block size to MB.
Further chain splits have occurred every six months to bring about upgrades to the network. When looking at the BTC network, it is rather unlikely to happen because of the sheer amount of hashing power and costs involved to undertake such an attack. Thankfully, no such attack has occurred. However, it has raised ongoing, unsettling questions for the BCH community surrounding its security. As BCH was founded to serve the purpose of a seamless and efficient payment, there has been some success in this area in recent years.
In a sure sign of its rising status, particularly in October , it was included by PayPal in the list of cryptocurrencies along with BTC, Ethereum, and Litecoin. Customers would now be able to buy and sell items using their accounts. In February , it was estimated that over 4, merchants worldwide now accept BCH so this number by now will likely be higher. This was a time that coincided with the famous crypto bull run.
In early , in line with many other cryptocurrencies, it saw a significant correction. However, as in-fighting in the BCH community took hold culminating in the hard fork with Bitcoin SV , its price tanked. Since then, its price has remained relatively stable. However, it did see a price surge in January , buoyed by the remarkable surge in the price of BTC. So, what do some crypto analysts think would happen to the price of BCH in the coming years? Indeed, it has been known as an altcoin with one of the strongest price correlations with BTC.
However, as an actual cryptocurrency to spend, its shorter transaction times and more significant block sizes undoubtedly make it better than BTC. So, as adoption becomes more widespread, and more people hopefully begin to use cryptocurrency for payments rather than see it as a store of value, then this could bode well for its prospects. Therefore, we are quite bullish on BCH as a long-term investment. Join us on Telegram and Reddit. Have any questions?

Mining pools also have a pool-specific share difficulty setting a lower limit for shares.
In Bitcoin network there's global difficulty set for all blocks. For block to be considered legitimate it has to have hash value lower than set target. Traditionally it's a hash function first 32 bits of which are equal to 0 while all the rest are 1 it is also called pdiff or pool difficulty. Bitcoin protocol provides target as a type with floating point and limited accuracy. Different Bitcoin clients often determine cryptocurrency difficulty based on this data.
Using following formula target can be obtained from any block. For example if a target packed in a block appears as 0x1bcb its hexadecimal version will look as following:. Maximum possible target with difficulty equal to 1 is defined as 0x1d00ffff which appears as following in hexadecimal numeration:.
Next is an easy way of difficulty calculation. It uses an altered version of Taylor series to logarithm and relies on logs to transform difficulty calculation. Difficulty is changed every blocks based on the time it took to discover previous blocks. If a block is found every 10 minutes as it was intended initially for even emission finding blocks will take exactly 2 weeks. If previous blocks were found in more than two weeks the cryptocurrency mining difficulty will be lowered, and if they were mined faster then that it will be raised.
The more or less time was spent on finding the previous blocks the more will difficulty be lowered raised. To mine a block hash has to be lower than targer proof-of-work.
