4. Bitcoin Cash (BCH)


Bitcoin Cash (or BCH) is a decentralized Peer-to-Peer electronic cryptocurrency cash that uses the Proof of Work (PoW) consensus protocol. it was created as a direct result of a Bitcoin (BTC) fork that occurred on 1st August 2017. Bitcoin blockchain has a 1 megabyte block size limit and transaction fees was $28 on average by the end of year 2017. Transactions sometimes took up to four days to complete in May 2017, hence it is impractical to use BTC for small purchases and everyday use.

Disputes on Bitcoin Scalability Solution

Part of the Bitcoin community called for the development team to increase the block size which will increase transaction speed significantly. Bitcoin core team refused the above proposal and decided instead to persue development of an unproven third party software, called the Lightning Network. Their objective is to use the lightning system to create another payment channel and layer that bypass the Bitcoin blockchain for two parties to transact BTC cryptocurrencies between each other. Lightning enables users to conduct many transactions outside of the Bitcoin blockchain and then record them as a single one.

The Hard Fork that created BCH

Because of the bypass, not every single cryptocurrency transaction will be recorded on the blockchain. Hence, Bitcoin core team hopes the lightning network can be successfuly developed to solve the scalability issue but this caused some members and groups of the community to hard fork and broke away from the Bitcoin blockchain. A new cryptocurrency, Bitcoin Cash (BCH) was created from the hard fork with block size limit of eight megabytes as compared to BTC's one megabyte size.
