Bitcoin Cash Hard Fork: Network Splits into BCH Node and BCH ABC

On November 15, the much-anticipated Bitcoin Cash (BCH) hard fork took place, resulting in the creation of two distinct chains: Bitcoin Cash Node (BCHN) and Bitcoin Cash ABC (BCH ABC). The fork occurred at block height 661,447, which marked the last common block shared by both chains.

This division highlights ongoing disagreements within the BCH community over the future direction of the network.

Why Did the Bitcoin Cash Hard Fork Happen?

1. Disagreement Over Network Rules

The split arose due to conflicts between the Bitcoin Cash Node and Bitcoin Cash ABC communities about proposed changes to the network’s rules.

• BCHN: Gained majority support from miners and users, emphasizing decentralization and opposing a developer fund implementation.
• BCH ABC: Proposed a controversial Infrastructure Funding Plan (IFP), redirecting 8% of block rewards to a developer fund.

2. Community and Network Signals

• Bitcoin Cash Node: Secured over 70% of network signaling support.
• Bitcoin Cash ABC: Garnered less than 1% support from miners and stakeholders.

Timeline of the Hard Fork

Block Height 661,447

The split officially occurred when the BCH network reached block 661,447, creating two separate chains.

Pre-Fork Movements

• Leading up to the hard fork, BCH holders transferred an average of 154,000 coins per day to exchanges, anticipating potential trading opportunities.

Exchanges and Industry Support

1. Major Exchange Stances

Prominent cryptocurrency exchanges, including Binance, Huobi, OKEx, and Kraken, announced their support for the fork ahead of time.

• Kraken’s Position: The exchange pledged support for Bitcoin Cash Node as the primary implementation, continuing to use the BCH ticker for BCHN.

2. Reasons for Supporting BCHN

Kraken cited BCHN’s overwhelming network support (70%) as the justification for its stance, compared to less than 1% support for BCH ABC.

Implications of the Fork

1. Two Competing Chains

The Bitcoin Cash network now consists of:

• Bitcoin Cash Node (BCHN): The dominant chain, supported by the majority of miners and exchanges.
• Bitcoin Cash ABC (BCH ABC): A minority chain with minimal support.

2. Ticker Symbol Usage

Exchanges and platforms have largely retained the BCH ticker for Bitcoin Cash Node, further solidifying its dominance.

3. Market Dynamics

• Increased trading activity due to the split, with users capitalizing on volatility.
• Potential for long-term competition between the two chains depending on adoption and development efforts.

What’s Next for BCHN and BCH ABC?

1. BCH Node (BCHN)

As the chain with majority support, BCHN is poised to:

• Maintain its position as the primary Bitcoin Cash network.
• Focus on decentralized governance and scalability.

2. BCH ABC

With limited support, BCH ABC faces challenges, including:

• Gaining traction among miners and developers.
• Justifying the Infrastructure Funding Plan (IFP) to attract adoption.

Conclusion

The Bitcoin Cash hard fork underscores the ongoing debate over governance and network funding in the cryptocurrency space. With Bitcoin Cash Node (BCHN) securing the lion’s share of support from miners, exchanges, and users, it appears to be the dominant chain moving forward.

However, the existence of Bitcoin Cash ABC (BCH ABC) introduces a competing vision, highlighting the diversity of thought within the BCH community. As the dust settles, the future of both chains will depend on their ability to innovate and attract adoption.
