BCH Hash War: A Tale of Controversy and Division200

In November 2018, the Bitcoin Cash (BCH) community experienced a tumultuous event known as the "Hash War." This event was the result of a deep division within the community over the future direction of the cryptocurrency and the underlying blockchain protocol.

At the heart of the conflict was a debate over the size of the blocks on the BCH blockchain. Blocks are the containers that hold transactions on a blockchain. Increasing the block size would allow more transactions to be processed within each block, reducing congestion on the network. However, critics argued that increasing the block size would compromise the security and decentralization of the network.

Two competing factions emerged within the BCH community. One faction, led by Roger Ver and Jihan Wu of Bitmain, proposed an increase in the block size to 32MB. This proposal was supported by a majority of the miners on the BCH network. The opposing faction, led by Craig Wright and Calvin Ayre, favored a block size of 8MB. They argued that a larger block size would lead to centralization and governance issues within the BCH ecosystem.

As the debate escalated, both factions began to engage in a "hash war," using their computing power to try to gain control of the BCH network. The hash war essentially involved each faction attempting to outbid the other in terms of hashing power, thereby increasing their influence over the outcome of the upcoming hard fork.

The hard fork, which occurred on November 15, 2018, resulted in the creation of two separate blockchains: Bitcoin Cash ABC (BCHABC) and Bitcoin Cash SV (BCHSV). BCHABC was supported by the faction led by Roger Ver and Jihan Wu, while BCHSV was supported by the faction led by Craig Wright and Calvin Ayre.

The hash war had a significant impact on the BCH community. It exposed deep divisions within the community and resulted in a loss of value for BCH holders. The split also led to a decrease in the hashrate of both BCHABC and BCHSV, making them more vulnerable to attack.

The legacy of the BCH hash war remains controversial. Some within the BCH community believe that the war was a necessary step in the evolution of the cryptocurrency. Others argue that it was a destructive event that damaged the reputation and credibility of BCH.

Regardless of one's perspective, the BCH hash war serves as a reminder of the challenges that can arise when a community is deeply divided over the future direction of a cryptocurrency. It is a cautionary tale about the importance of consensus and compromise in the world of blockchain technology.
