The Bitcoin Cash network has experienced yet another hard fork, splitting into two separate blockchains. This latest division reflects ongoing ideological and technical disagreements within the community, echoing past schisms that have shaped the cryptocurrency’s turbulent history.
At the time of the split, the network divided into Bitcoin Cash ABC (BCH ABC) and Bitcoin Cash Node (BCHN). While both chains emerged from the same genesis, only one has gained significant traction. According to blockchain data from Coin.Dance, BCHN quickly secured mining support, while BCH ABC received little to no hashpower in the immediate aftermath.
The final shared block between the two chains was block #661647, mined by Binance. The first divergent block was mined by AntPool—marking the official start of the fork—and since then, the majority of miners have consistently extended the BCHN chain.
This shift was anticipated. Prior to the fork, approximately 80% of miners signaled support for BCHN, indicating a strong preference within the mining community for a version of Bitcoin Cash free from controversial funding mechanisms.
The Root of the Split: The “Coinbase Rule” Controversy
The primary catalyst behind the split was a proposed update by the Bitcoin Cash ABC development team, led by Amaury Sechet. Their upgrade included a contentious feature known as the “Coinbase Rule.” Under this rule, 8% of every newly mined Bitcoin Cash block would be redirected to the BCH ABC development team to fund ongoing protocol improvements.
Critics labeled this mechanism a “miner tax,” arguing it unfairly diverted rewards from miners to a centralized group of developers. Opponents, including the Bitcoin Cash Node (BCHN) faction, rejected this model as incompatible with decentralized principles. In response, BCHN developers released a version of the software that removed the Coinbase Rule entirely.

When a significant portion of a network’s nodes adopt different software rules—especially during a hard fork—the blockchain splits into two parallel chains. One follows the new rules; the other maintains the old. In this case, BCHN preserved the pre-fork economic model, while BCH ABC introduced the new funding mechanism.
Market Reaction and Exchange Support
In the days leading up to the fork, Bitcoin Cash prices dropped sharply. Data from CoinDesk 20 showed the price falling to **$237.54**, down 7.5% from a recent high of $256.82. Market volatility around forks is common, as uncertainty about chain viability and token distribution leads to sell-offs.
However, confidence in BCHN grew rapidly post-fork due to strong miner support and widespread exchange endorsements. Most major cryptocurrency exchanges—including OKX, Kraken, and Bitfinex—announced they would recognize BCHN as the legitimate continuation of Bitcoin Cash and retain the “BCH” ticker for it.
This decision effectively sidelined BCH ABC in terms of market relevance. Without sufficient hashpower or exchange backing, a blockchain struggles to maintain security, liquidity, and user adoption—three pillars critical to long-term survival.
Will BCH ABC Survive?
For any blockchain to remain functional, it must attract consistent mining power to validate transactions and prevent attacks like double-spending. In the absence of such support, the chain risks becoming stagnant or even disappearing entirely.
As of now, BCH ABC has failed to gain meaningful hashpower, raising serious doubts about its longevity. While it technically exists, its lack of miner participation means few transactions are being processed, and its network difficulty adjustments may not be sufficient to sustain regular block production.
In contrast, BCHN has demonstrated resilience, with multiple consecutive blocks mined and growing consensus among developers, miners, and exchanges.

Frequently Asked Questions (FAQ)
Q: What caused the Bitcoin Cash split in 2020?
A: The split was triggered by a disagreement over the “Coinbase Rule,” which would redirect 8% of mining rewards to fund BCH ABC development. BCHN rejected this as a “miner tax,” leading to a hard fork.
Q: Which chain is considered the real Bitcoin Cash?
A: The majority of exchanges and miners recognized Bitcoin Cash Node (BCHN) as the legitimate continuation of Bitcoin Cash, assigning it the original “BCH” ticker symbol.
Q: Did BCH ABC disappear after the fork?
A: While BCH ABC still exists technically, it failed to attract sufficient hashpower or exchange support, rendering it largely inactive and irrelevant in practice.
Q: How do hard forks affect cryptocurrency prices?
A: Hard forks often cause short-term price drops due to uncertainty. However, if one chain gains clear dominance—like BCHN did—price stability typically returns as confidence rebuilds.
Q: Can users claim new coins after a Bitcoin Cash fork?
A: Yes, users who held BCH before the fork were entitled to claim an equal amount on both chains—provided they controlled their private keys and used compatible wallets.
Q: Why is miner support so important after a fork?
A: Miners secure the network by validating transactions. Without enough hashpower, a blockchain becomes vulnerable to attacks and cannot process transactions reliably.
The Bigger Picture: Governance in Decentralized Networks
This split highlights a recurring challenge in decentralized ecosystems: how to fund development without compromising decentralization. While developer funding is essential for innovation, mechanisms like mandatory redistribution raise concerns about centralization and fairness.
The rejection of the miner tax suggests that the Bitcoin Cash community values miner autonomy and open competition over directed funding models. It also reinforces a broader trend in crypto: communities tend to resist changes perceived as enriching insiders at the expense of participants.
Looking ahead, future upgrades will likely face intense scrutiny. Any proposal affecting economic incentives must achieve broad consensus—or risk another divisive fork.

Conclusion
The 2020 Bitcoin Cash split into BCHN and BCH ABC was more than just a technical divergence—it was a referendum on governance, fairness, and community control. With overwhelming miner and exchange support, BCHN emerged as the dominant chain, while BCH ABC faded into obscurity due to lack of adoption.
For investors and users, this event serves as a reminder: in cryptocurrency, code is law—but consensus is power. Understanding how forks work, what drives them, and which chains survive is crucial for navigating this dynamic space safely and strategically.
