Bitcoin and Bitcoin Cash are two of the most widely known cryptocurrencies in the world. They share many similarities, such as their decentralized nature, use of blockchain technology, and the fact that they are based on the same underlying code. However, there are also several key differences between the two currencies that set them apart.
Today’s article dives deep into the difference between Bitcoin and Bitcoin Cash. I will discuss their history, features, and use cases. I will also give you a closer look at the key factors that differentiate them, including block size, smart contract functionality, token issuance, and the replace-by-fee feature.
By the end of this article, you will have a comprehensive understanding of the similarities and differences between Bitcoin and Bitcoin Cash, and be able to make an informed decision about which one is better and why.
Bitcoin is a decentralized digital currency that uses blockchain technology to record and verify transactions. It was created in 2009 by an individual or group of individuals using the pseudonym Satoshi Nakamoto.
Unlike traditional currencies, which are issued and backed by a central authority such as a government, Bitcoin operates on a peer-to-peer network. This means that transactions are processed directly between users without the need for a middleman.
One of the key features of Bitcoin is its use of blockchain technology. A blockchain is a digital ledger that is used to record and verify transactions. Each block in the chain contains a record of multiple transactions, and once a block is added to the chain, the information it contains cannot be altered or deleted. This provides a high level of security and transparency for the network.
Another important aspect of Bitcoin is its decentralized nature. Unlike traditional currencies, which are controlled by a central authority, the Bitcoin network is maintained by a distributed network of users. This means that no single entity has control over the currency, making it resistant to censorship and manipulation.
To use Bitcoin, individuals must first acquire a digital wallet, which can be used to store, send, and receive the currency. Transactions are processed by the network and are recorded on the blockchain. Users can also use the digital currency to make purchases from merchants that accept it as a form of payment.
In summary, Bitcoin is a decentralized digital currency that uses blockchain technology to record and verify transactions. It operates on a peer-to-peer network and is not controlled by any central authority. With the use of digital wallet and the decentralized nature of Bitcoin make it a secure and transparent way of making transactions.
Bitcoin Cash (BCH) is a cryptocurrency that was created in 2017 as a fork of the original Bitcoin (BTC) blockchain. It was created as a solution to the scalability issues that were present in the original Bitcoin network.
One of the main differences between Bitcoin and Bitcoin Cash is the block size limit. In the original Bitcoin network, the block size limit is set at 1 megabyte, which limits the number of transactions that can be processed in each block. This can lead to delays and higher transaction fees, especially during times of high network usage.
Bitcoin Cash increased the block size limit to 8 megabytes, which allows for more transactions to be processed in each block. This helps to reduce delays and lower transaction fees.
Additionally, Bitcoin Cash also introduced other changes to the protocol, such as the implementation of a new difficulty adjustment algorithm called Emergency Difficulty Adjustment (EDA) which is designed to help stabilize the network and prevent wild fluctuations in block time.
Bitcoin Cash also uses a different transaction signature algorithm called Schnorr signature algorithm which allows for more transactions to be included in each block. This leads to faster transaction processing times, and lower fees.
Another important difference between the two is that Bitcoin Cash is a hard fork of Bitcoin. This means that it was created by duplicating the entire Bitcoin blockchain and then making changes to the code. As a result, Bitcoin Cash has its own unique blockchain and is not directly compatible with the original Bitcoin network.
In terms of adoption, Bitcoin Cash is not as widely used and accepted as Bitcoin. However, it still has a dedicated community of users and developers and can be used for transactions and purchases at merchants that accept it as a form of payment.
Bitcoin Cash hard forked from Bitcoin on August 1st, 2017. The main reason for the hard fork was to address the scalability issues that were present in the original Bitcoin network.
The main issue was the 1 megabyte block size limit that was present in the original Bitcoin network. This limit placed a constraint on the number of transactions that could be processed in each block, leading to delays and higher transaction fees, especially during times of high network usage.
Some members of the Bitcoin community proposed increasing the block size limit to allow for more transactions to be processed in each block, thus reducing delays and lowering transaction fees. However, not all members of the community agreed on this solution, leading to a divide in the community.
This divide led to the creation of Bitcoin Cash, which increased the block size limit to 8 megabytes. This allows for more transactions to be processed in each block and helps to reduce delays and lower transaction fees.
Additionally, Bitcoin Cash also introduced other changes to the protocol, such as the implementation of a new difficulty adjustment algorithm called EDA which is designed to help stabilize the network and prevent wild fluctuations in block time.
It's important to note that the hard fork was not a smooth process, and the split was quite controversial. Some exchanges and wallets didn't support the fork, and that caused confusion and uncertainty among the users.
Bitcoin and Bitcoin Cash are different in five key areas: difficulty adjustment, block size, smart contract functionality, token issuance, and replace-by-fee. The following sections explain in detail how Bitcoin Cash differs from Bitcoin in each area.
Difficulty adjustment algorithm is a mechanism that controls how difficult it is to mine new blocks in a blockchain. The difficulty is adjusted periodically to ensure that new blocks are mined at a consistent rate, regardless of the number of miners on the network.
In Bitcoin, the difficulty is adjusted every 2016 blocks, using a mechanism called the "Bitcoin Difficulty Adjustment Algorithm" (DAA). The DAA uses a moving average of the time it took to mine the previous 2016 blocks and adjusts the difficulty accordingly. This mechanism is designed to ensure that new blocks are mined at a rate of one every 10 minutes, on average.
Bitcoin Cash uses a different difficulty adjustment algorithm called Emergency Difficulty Adjustment (EDA). The EDA algorithm is designed to respond more quickly to changes in the hashrate of the network. It uses a different approach to adjust the difficulty, it checks if the last 6 blocks were mined faster or slower than 12 hours and it adjusts difficulty accordingly. This mechanism is designed to prevent wild fluctuations in block time and to stabilize the network.
One of the main differences between Bitcoin and Bitcoin Cash is the block size limit. In the original Bitcoin network, the block size limit is set at 1 megabyte, which limits the number of transactions that can be processed in each block. This can lead to delays and higher transaction fees, especially during times of high network usage.
Bitcoin Cash increased the block size limit to 8 megabytes, which allows for more transactions to be processed in each block. This helps to reduce delays and lower transaction fees. With a larger block size limit, more transactions can be included in each block, which means that more transactions can be processed by the network in a shorter period of time. This can help to reduce the backlog of pending transactions and prevent delays.
It's important to note that increasing the block size limit does come with some trade-offs. Larger block size limit means that the size of the blockchain will grow faster and will require more storage space for the full nodes. It also means that the network will need more computational power and bandwidth to process and propagate the larger blocks.
A smart contract is a digital contract that can be programmed to automatically execute certain actions based on certain conditions. Smart contracts have the potential to revolutionize the way transactions are done, by allowing for more complex and automatic execution of agreements.
Bitcoin, being the first and original blockchain, does not have native support for smart contracts. However, some developers have created solutions such as the Bitcoin Script, which allows for the creation of simple smart contracts on the Bitcoin network.
The problem is that these solutions are limited in terms of functionality and can only be used to create simple scripts. Such scripts can't be compared to, nor replace, the smart contract functionality of other complex blockchains like Ethereum.
Bitcoin Cash utilizes Cashscript to bring decentralized finance (DeFi) and general smart contract functionality to its blockchain. Cashscript may help Bitcoin Cash compete with Bitcoin and Ethereum – albeit it’s worth noting that the interest isn’t there yet.
Bitcoin does not have native support for token issuance. However, it is possible to create tokens on the Bitcoin blockchain using a technique called "colored coins". Colored coins is a method of tokenizing assets on the blockchain, where a specific amount of Bitcoin is "colored" to represent a specific asset, such as a stock or a piece of real estate.
Colored coins allow for the creation of tokens on the Bitcoin blockchain, but it is a complex and not widely adopted method. It also doesn’t allow for the issuance of new non-BTC tokens.
Bitcoin Cash has introduced new opcodes that allow for the creation of more advanced smart contracts and token issuance. These new opcodes allow for the creation of tokens on the Bitcoin Cash blockchain using the same mechanism that is used on other blockchain platforms, like the creation of ERC-20 tokens on Ethereum network.
Bitcoin Cash utilizes the Simple Ledger Protocol (SLP) to allow developers to issue new tokens on top of the BCH blockchain. The feature grants the BCH community to access and issue new cryptocurrencies much like they would do on a blockchain such as Ethereum.
Replace-by-Fee (RBF) is a mechanism that allows users to replace an unconfirmed transaction with a new one that includes a higher fee. This is useful when a transaction is stuck and is not being confirmed because the fee was too low. By using RBF, users can increase their transaction fee, making it more attractive for miners to include in the next block.
In Bitcoin, RBF is an optional feature that can be enabled by the user. It is supported by most wallets and is considered a best practice for transactions with low fees. It is also supported by most full nodes and mining pools, making it widely available to users.
Bitcoin Cash, on the other hand, has a more complex approach to RBF. Bitcoin Cash has two different transaction types, the "Standard Transaction" and the "Child Pays for Parent (CPFP)" transaction. The standard transaction works in the same way as Bitcoin's RBF, allowing users to replace an unconfirmed transaction with a new one that includes a higher fee.
The CPFP transaction, on the other hand, is a mechanism that allows a user to add a high fee to a parent transaction that includes a low fee, incentivizing the miner to include both the parent and the child transactions in the same block.
Bitcoin and Bitcoin Cash are two different cryptocurrencies. One was created by Satoshi Nakamoto in 2009, while the other was created as a result of a hard fork in the original Bitcoin blockchain. Both currencies share many similarities, such as their decentralized nature, use of blockchain technology, and the fact that they are based on the same underlying code.
However, there are also several key differences between the two currencies that set them apart. Block size represents the most notable difference.
Bitcoin has stuck to its 1MB block size. On the other hand, Bitcoin Cash has quadrupled its 8MB block size since launching. Bitcoin Cash also upgrades its network much more frequently and regularly introduces new features.
Bitcoin Core developers are very careful with pushing new updates. They work towards perfecting two important scalability features, SegWit and Lightning Network, in order to make the blockchain more efficient.
Both networks have the same monetary policy. The difference is that Bitcoin Core focuses on preserving user anonymity, decentralization, and censorship-resistance. On the other hand, Bitcoin Cash sacrifices some of these features for lower fees and faster transaction time.
The adoption rate of both networks is enough evidence to show which Bitcoin is better. Although Bitcoin Cash had some hopes of gathering adoption during its early days of launching, there isn’t much interest in Bitcoin Cash among the crypto community anymore.
Bitcoin remains king. Whoever wishes to save on transaction time and fees is free to try out Bitcoin Cash. But it’s obvious by now that Bitcoin Cash has no chance of replacing Bitcoin or even coming close to its level of adoption.
