BCH: A SegWit-Activated Hard Fork of Bitcoin158

Introduction
Bitcoin Cash (BCH) is a cryptocurrency that emerged as a hard fork of Bitcoin (BTC) in 2017. The fork was the result of a debate within the Bitcoin community over how to scale the blockchain. Bitcoin Cash proponents advocated for an increase in the block size limit from 1MB to 8MB, while Bitcoin Core developers preferred a more gradual approach. The larger block size allows for more transactions to be processed per block and potentially increases the network's throughput.
Technical Features
BCH shares many similarities with BTC, including its proof-of-work consensus mechanism and its use of the SHA-256 hashing algorithm. However, there are several key differences between the two cryptocurrencies:
* Block Size Limit: BCH has a block size limit of 8MB, which is eight times larger than BTC's 1MB limit. This allows for more transactions to be processed per block, increasing the network's potential throughput.
* Difficulty Adjustment Algorithm: BCH uses an algorithm called the Adjustable Block Difficulty (ABD) to adjust the mining difficulty every block, rather than every two weeks like BTC. This helps maintain a consistent block time and prevents large swings in mining difficulty.
* Transaction Signature Algorithm: BCH employs multiple signature algorithms, including ECDSA and Schnorr signatures. This flexibility allows for reduced transaction sizes and improved scalability.
Adoption and Usage
BCH has gained significant adoption among users and businesses, although it remains less widely accepted than BTC. It is supported by several major cryptocurrency exchanges, including Coinbase, Kraken, and Binance. BCH is also accepted by a growing number of merchants and retailers, both online and offline.
Controversies and Challenges
Since its inception, BCH has faced several controversies and challenges. One major concern is its perceived centralization, as a small number of mining pools control a significant proportion of the network's hashrate. Additionally, BCH has experienced several contentious hard forks, including the Bitcoin SV (BSV) split in 2018.
Conclusion
BCH remains a relevant cryptocurrency with a strong community and a unique set of features. Its larger block size limit and adjustable difficulty adjustment algorithm offer potential advantages over BTC in terms of scalability and transaction throughput. However, its centralization concerns and history of hard forks present challenges that the community must address for BCH to gain widespread adoption.
