Bitcoin’s journey since its inception has been marked by innovation, adoption, and—perhaps most notably—division. Forks, both hard and soft, have played a pivotal role in shaping the cryptocurrency landscape. From the landmark BTC-BCH split in 2017 to the ongoing debates within the BCH community, blockchain evolution often comes at the cost of consensus. As whispers of another potential BCH fork emerge, it's time to revisit the history, mechanics, and implications of these digital schisms.
The Origins of Bitcoin Forks
At the heart of every fork lies a disagreement—a divergence in vision among developers, miners, and users about how the network should evolve. In Bitcoin’s early days, Satoshi Nakamoto imposed a 1MB block size limit to prevent spam attacks and ensure network stability. While effective initially, this constraint soon became a bottleneck as user adoption grew.
With only about 7 transactions per second (tps) possible under the 1MB limit, transaction queues lengthened and fees rose. The solution? Blockchain scalability. But even agreeing on how to scale proved divisive.

This fundamental debate over Bitcoin scalability led to the first major split in 2017.
The 2017 Split: Birth of Bitcoin Cash (BCH)
On August 1, 2017, the Bitcoin network underwent a hard fork, resulting in two separate chains: Bitcoin (BTC) and Bitcoin Cash (BCH). Unlike a soft fork, which maintains backward compatibility, a hard fork creates an entirely new chain that operates under different rules.
The primary motivation behind BCH was increasing block size—from 1MB to 8MB (later increased further)—to enable faster and cheaper transactions. Proponents believed this aligned more closely with Satoshi’s original vision of peer-to-peer electronic cash.
However, critics argued that larger blocks compromised decentralization by making it harder for regular users to run full nodes. This ideological rift marked the beginning of recurring tensions within the broader Bitcoin ecosystem.
The 2018 War: BCH Divides Into BCHA and BSV
Just over a year later, in November 2018, Bitcoin Cash faced another crisis. A power struggle erupted between two factions:
- Bitcoin ABC (now BCHA) – backed by mining giant Bitmain and developer吴忌寒 (Jihan Wu)
- Bitcoin SV (BSV) – championed by Craig Wright (self-proclaimed "Satoshi") and Calvin Ayre
The conflict centered around protocol changes proposed by Bitcoin ABC, including re-introducing certain opcodes and adjusting block processing rules. BSV supporters viewed these changes as deviations from original Bitcoin principles.
What followed was a hash war—a costly battle for mining dominance. Miners poured resources into supporting their preferred chain, driving up difficulty and energy consumption. Ultimately, both chains survived, but BCH’s market value plummeted—dropping over 40% in three weeks. Even BTC felt the ripple effects, falling more than 30%.
This event underscored a harsh truth: forks are not just technical events—they are economic and psychological shocks.
Is Another BCH Fork Coming in 2025?
History may be repeating itself. In recent developments, a new contender has emerged: BCH Node (BCHN). Launched in early 2025 by Freetrader, an early BCH contributor, BCHN opposes the Infrastructure Funding Plan (IFP) introduced by Bitcoin ABC.
Under IFP, 8% of mining rewards are redirected to fund development efforts. While intended to ensure long-term sustainability, many in the community see it as centralized control creeping into a decentralized system.
Freetrader and allies argue that development should be funded voluntarily—not mandated through miner taxation. Their alternative, BCHN, runs without IFP, promoting what they call “true decentralization.”
So Who’s Winning This Time?
Current indicators suggest BCHN holds significant momentum:
- Mining Support: In the last 1,000 blocks analyzed, BCHN mined 743 compared to just 8 by Bitcoin ABC.
- Market Price: On major exchanges like CoinEx, BCHN trades at over 13 times the price of BCHA.
- Community Sentiment: Western communities largely favor BCHN; Chinese communities remain neutral but watchful.
While exchanges have yet to officially recognize either chain as the Bitcoin Cash, widespread node adoption and miner support make BCHN the frontrunner.

Hard Fork vs Soft Fork: What’s the Difference?
Understanding the types of forks is crucial for grasping their impact:
Hard Fork
- Introduces incompatible changes to the protocol
- Results in two separate chains after activation
- Requires all participants to upgrade
- Often leads to new cryptocurrencies (e.g., BCH from BTC)
Soft Fork
- Implements backward-compatible upgrades
- Old nodes can still validate new blocks (though with limited functionality)
- Maintains a single chain
- Less disruptive but offers limited long-term scalability
In essence, hard forks drive innovation through division, while soft forks promote unity through compromise—but neither solves underlying governance issues.
Impact of Forks on Markets and Trust
Every fork carries consequences beyond code:
- Price Volatility: Uncertainty triggers sell-offs; speculative traders exploit price swings.
- Network Security Risks: Split hash power weakens protection against attacks.
- User Confusion: Non-technical holders struggle to manage multiple assets post-fork.
- Erosion of Trust: Repeated splits challenge perceptions of stability and decentralization.
The repeated fracturing of communities raises deeper questions: Can a decentralized system survive constant internal conflict? Does frequent forking undermine faith in Bitcoin’s foundational principle—consensus?
Frequently Asked Questions (FAQ)
Q: What happens to my coins during a fork?
A: If you hold BCH before the split, you typically receive an equal amount of both resulting tokens. However, actual distribution depends on exchange policies and wallet support.
Q: How do I know which chain is legitimate?
A: There’s no central authority. Legitimacy is determined by community consensus, mining power, exchange listings, and node adoption.
Q: Are forks good or bad for crypto?
A: They’re double-edged swords. Forks allow innovation and ideological freedom but can fragment ecosystems and reduce security.
Q: Can a fork be reversed?
A: No. Once a fork occurs and transactions are confirmed on both chains, it becomes permanent unless both sides agree to merge—a near-impossible scenario.
Q: Should I invest in both forked coins?
A: Only after thorough research. One chain may survive long-term; others may fade due to lack of support.
Q: How do exchanges handle forks?
A: Most pause deposits/withdrawals until the outcome is clear. They then list the dominant chain and may distribute secondary tokens later.
Final Thoughts: Consensus in Crisis
Forks are symptoms of a living, breathing ecosystem—one where debate and dissent are natural. Yet too many splits risk turning vibrant communities into battlegrounds.
As we look ahead to potential developments in 2025, one thing remains clear: the strength of any blockchain lies not in its code alone, but in the shared belief of those who sustain it.
Whether BCHN or BCHA prevails, the real winner will be determined not by developers or miners—but by users voting with their nodes, wallets, and wallets.
