In the world of cryptocurrencies, the term "hard fork" often carries a sense of legitimacy—implying an upgrade or evolution of an existing blockchain. But beneath the technical surface, a hard fork shares more in common with a newly created altcoin than many users realize. At its core, a hard fork is a new cryptocurrency launched through a backward-incompatible change, inheriting the transaction history of its predecessor but operating under new rules.
This article explores why hard forks should be viewed not as upgrades, but as altcoins by nature, and how their creation mirrors the launch mechanisms of other alternative digital currencies.
The Origins of Bitcoin and Its Legacy
Bitcoin, launched in January 2009, remains the first and longest-running cryptocurrency. Its blockchain—a distributed ledger tracking ownership across addresses—was designed with backward compatibility in mind. In theory, the original Bitcoin software could still validate today’s network, a testament to its stability and conservative development philosophy.
Unlike later digital currencies, Bitcoin had no direct predecessor. Every other cryptocurrency that followed, whether through innovation or imitation, exists in Bitcoin’s shadow. This foundational role makes Bitcoin unique: it wasn’t forked from anything. It began from zero.

What Defines an Altcoin?
From 2011 onward, numerous alternative cryptocurrencies—commonly called altcoins—emerged for various technical, economic, or ideological reasons. These include:
- Litecoin: Faster block times and a different hashing algorithm.
- Namecoin: Aimed at decentralized domain name registration.
- IxCoin: Featured a controversial premine, allocating coins to creators before public release.
Premine models often face criticism for unfair distribution, especially when large portions go to developers without public access. More transparent projects like Litecoin avoided premines entirely, announcing mining availability in advance to ensure fairness.
Another model, the developer tax, automatically directs a portion of block rewards to fund ongoing development. Zcash is one of the most well-known examples using this approach.
These altcoins share a common challenge: establishing value where none existed before. Since they don’t inherit trust or user base from an existing network, they must create both through marketing, community building, and utility.
The Rise of ICOs and Token Distribution
The introduction of Initial Coin Offerings (ICOs) around 2013—starting with Mastercoin (now Omni)—changed how new tokens entered the market. Projects like Ethereum, Maidsafe, and Factom used ICOs to raise capital by selling tokens early to investors.
ICOs function similarly to premines: they distribute tokens before network launch, often retaining significant allocations for teams and foundations. The raised funds support development and marketing, helping bootstrap adoption. In essence, ICOs are a financial mechanism for launching new digital assets with built-in initial distribution.
Understanding Hard Forks
A hard fork occurs when a blockchain undergoes a backward-incompatible protocol change. Nodes running the new software no longer accept blocks from older versions, effectively splitting the network into two:
- One chain continues with the original rules.
- The other operates under new consensus rules.
The most famous example is Bitcoin Cash (BCH), which forked from Bitcoin in August 2017. BCH kept Bitcoin’s transaction history but increased block size and altered signature hashing—changes that broke compatibility.
Despite sharing historical data, Bitcoin and Bitcoin Cash are now separate networks with distinct communities, miners, and values.
Hard Forks vs. Altcoins: A False Distinction
At first glance, hard forks seem different from altcoins because they “emerge” from existing blockchains. But structurally, they’re nearly identical:
- Both involve new software with altered consensus rules.
- Both require a starting state for their ledger.
- Both distribute coins to users based on prior holdings—or developer decisions.
In fact, a hard fork is simply an altcoin that uses the old chain’s ledger as its genesis state. Instead of starting from zero like Litecoin or distributing via ICO like Ethereum, it performs a snapshot of existing balances and launches a parallel system.
This method—sometimes called a "snapshot fork"—gives the illusion of continuity. But technically, it's a new cryptocurrency born with pre-distributed wealth matching the parent chain.
Consider Bitcoin Gold or Bitcoin Private: these forks combined Bitcoin’s ledger snapshot with additional allocations to developers—essentially replicating premine strategies used by traditional altcoins.
The Problem of Value Creation
All new cryptocurrencies face the same fundamental question: Why should this asset have value?
Altcoins attempt to answer this through utility (e.g., smart contracts on Ethereum), scarcity (e.g., Litecoin’s capped supply), or community (e.g., Dogecoin). ICOs rely on investor belief in future potential.
Hard forks sidestep this challenge by piggybacking on existing trust and distribution. By copying the parent chain’s ledger, they inherit perceived legitimacy and immediate exchange listings. But this doesn’t eliminate the need for long-term value justification.
As Jimmy Song points out: “They are essentially created out of thin air—so why would anyone give up something valuable for them?”

Ledger Initialization: A Missed Opportunity
One major inefficiency in most hard forks is their insistence on copying the entire transaction history—often over 150GB for Bitcoin—just to preserve balance records.
Technically, only the UTXO set (unspent transaction outputs) is needed to determine current ownership. Projects like BTX and BTCP have adopted this leaner approach, initializing their ledgers with just ~3GB of UTXO data.
This method reduces node storage requirements, speeds up synchronization, and lowers barriers to entry for new participants. Yet many hard forks avoid it—not for technical reasons, but political ones.
By preserving full history, chains like Bitcoin Cash or Ethereum Classic signal continuity with the past, reinforcing claims of being the “true” version. Abandoning old blocks might admit they are, in fact, new coins.
Ethereum Classic: A Case Study
After The DAO hack in 2016, Ethereum executed a hard fork to reverse stolen funds. Most of the community migrated to the new chain (ETH), while a minority continued on the original chain as Ethereum Classic (ETC).
This event proved that social consensus, not code or history, determines which chain survives. ETC wasn't technically superior—it was ideologically preferred by those who believed "code is law."
ETC also demonstrated that both chains can coexist, each functioning as independent cryptocurrencies with separate markets and development paths.
Hard Forks as Political Tools
Because hard forks allow rule changes without coordination across all stakeholders, they introduce subjectivity into what should be objective systems. Developers gain power to alter supply, reward structures, or even rewrite history—undermining decentralization.
Over time, frequent hard forks may lead to increased centralization, as only well-funded teams can manage complex upgrades and marketing campaigns needed to gain traction.
Moreover, each fork increases fragmentation:
- Users must manage multiple assets.
- Exchanges decide which chains to support.
- Miners choose where to allocate resources.

Conclusion: Hard Forks Are Altcoins
A backward-incompatible software update creates a new cryptocurrency—by definition. Whether labeled a “fork” or a “new coin,” the outcome is the same: two ledgers, two sets of rules, two markets.
Calling a hard fork an “upgrade” obscures its true nature. Like any altcoin:
- It requires new software.
- It establishes a new consensus mechanism.
- It distributes assets based on arbitrary criteria (often favoring insiders).
The only real difference is branding: hard forks inherit legacy credibility, making them appear more legitimate than standalone altcoins—even when their economic models are equally speculative.
As blockchain ecosystems evolve, users must recognize that not all forks are progress, and not all “upgrades” benefit decentralization. True innovation lies not in changing rules unilaterally, but in building systems resilient enough to endure them.
Frequently Asked Questions (FAQ)
Q: Is every hard fork considered an altcoin?
A: Yes—technically speaking, any backward-incompatible change creates a new cryptocurrency with its own rules and network. Even if it shares history with another chain, it functions independently.
Q: How do hard forks differ from soft forks?
A: Soft forks are backward-compatible updates; old nodes can still validate new blocks. Hard forks break compatibility, requiring all participants to upgrade or risk splitting off onto a separate chain.
Q: Can a hard fork succeed without community support?
A: No. Technical execution isn’t enough—adoption depends on miners, exchanges, wallets, and users accepting the new chain. Without broad consensus, the forked coin typically fails or has minimal value.
Q: Why do some hard forks keep full blockchain history?
A: To maintain the appearance of continuity and legitimacy. However, technically only unspent outputs (UTXOs) are necessary for balance validation.
Q: Are premines and developer taxes ethical in hard forks?
A: This is debated. While they fund development, they concentrate wealth among insiders. Transparency and fair distribution are key to long-term trust.
Q: Does inheriting Bitcoin’s ledger give BCH more value than other altcoins?
A: Not inherently. Value comes from utility, security, adoption—not historical data. Many successful altcoins started from scratch without copying existing chains.
