Bitcoin Cash is a cryptocurrency, created from a hard fork from the Bitcoin blockchain in 2017. A hard fork is when a blockchain splits, with no compatibility between the two forks. This is a radical change to a network's protocol that makes previously invalid blocks and transactions valid, or vice versa. A hard fork requires all nodes or users to upgrade to the latest version of the protocol software.2

Bitcoin Cash is designed to be used as a cheap payment system, much in the way Bitcoin was designed to be originally. Transactions fees are generally less than $.01, and transaction confirmation times are significantly less than Bitcoin's, generally within seconds.

Bitcoin Cash was created and is maintained by an active community of developers. These developers still see Bitcoin Cash as a necessary alternative to Bitcoin, because in their view, Bitcoin has become more of an investment instrument than a payment system. It was designed as a peer-to-peer payment system that removes regulatory authorities and other third parties from financial transactions.3

Bitcoin Cash operates on Bitcoin Cash Node, which is an ecosystem that enables users to transact in Bitcoin Cash. Bitcoin Cash Node is the blockchain for Bitcoin Cash, and can be thought of as the virtual machine that runs the network, powering transactions.

How Is Bitcoin Cash Different From Bitcoin?

Bitcoin Cash proposed to resolve the situation by increasing the size of blocks to between 8 MB and 32 MB, enabling mor transactions to be processed per block. The average number of transactions per block on Bitcoin at the time Bitcoin Cash was proposed was between 1,000 and 1,500.7

Bitcoin Cash also differs from bitcoin in another respect, as it does not incorporate Segregated Witness (SegWit), another solution proposed to accommodate more transactions per block. SegWit retains only information or the metadata relating to a transaction in a block. Typically, all details pertaining to a transaction are stored in a block. 

Bitcoin Cash also has increased the size of the blocks on the blockchain throughout its history—in 2018, its block size was 8MB. In June 2022, the block size increased again to 32MB.8

One of the key benefits of Optimism Blockchain is its ability to significantly increase the transaction throughput of Ethereum. This is achieved by bundling multiple transactions into a single batch and processing them off-chain. Once the batch is processed, the results are verified on-chain, ensuring the security and immutability of the Ethereum blockchain.

Another major advantage of Optimism Blockchain is its ability to reduce transaction fees. By processing transactions off-chain, the cost of gas fees is significantly reduced, making it more affordable for users to transact on the Ethereum network.

In addition to its scalability and cost-effectiveness, Optimism Blockchain is also known for its high level of security. The technology is designed to ensure that all transactions are verified on-chain, making it impossible for malicious actors to compromise the integrity of the Ethereum blockchain.

Overall, Optimism Blockchain is an exciting development in the world of blockchain technology. Its ability to increase transaction throughput, reduce transaction fees, and enhance security makes it a promising solution for the challenges faced by the Ethereum network. As the adoption of blockchain technology continues to grow, it is likely that we will see more innovation in the field of layer 2 scaling solutions, and Optimism Blockchain is well-positioned to be at the forefront of this innovation.
