Bitcoin Cash (BCH) is a peer-to-peer cryptocurrency that emerged as a result of a hard fork from Bitcoin (BTC) on August 1, 2017. The fork was initiated by a group of developers and miners who were concerned about Bitcoin’s scalability issues, particularly its limited block size of 1 megabyte.
Bitcoin Cash was created to address these concerns by increasing the block size limit, allowing for more transactions to be processed in each block. The increased block size (initially set to 8 megabytes, later increased further) was intended to improve the scalability of the Bitcoin network, enabling faster and cheaper transactions.
Key features of Bitcoin Cash include:
- Larger block size: Bitcoin Cash initially had a block size limit of 8 megabytes, which was later increased further through network upgrades. This larger block size allows for more transactions to be included in each block, potentially reducing transaction congestion and lowering fees.
- Lower transaction fees: With its larger block size, Bitcoin Cash aims to provide lower transaction fees compared to Bitcoin. This makes it more suitable for everyday transactions and microtransactions.
- Faster transaction confirmation: The larger block size and potentially lower congestion on the Bitcoin Cash network can result in faster confirmation times for transactions compared to Bitcoin.
- Decentralization: Like Bitcoin, Bitcoin Cash operates on a decentralized network of nodes, with no central authority controlling the network or its issuance.
Bitcoin Cash shares many similarities with Bitcoin, including its proof-of-work consensus mechanism (based on the SHA-256 hashing algorithm), supply limit (21 million coins), and overall philosophy of peer-to-peer electronic cash. However, it differs primarily in its approach to scalability and transaction processing.
Since its inception, Bitcoin Cash has gained a significant following and has been embraced by some merchants and users as an alternative to Bitcoin for everyday transactions. However, it has also faced criticism and controversy within the cryptocurrency community, particularly regarding its contentious fork from Bitcoin and debates over its development direction.
