This is a comprehensive breakdown of the “civil war” within the Bitcoin ecosystem. To make this accessible to an English-speaking audience, I have translated and adapted the content, ensuring the nuances of the “Small Block vs. Big Block” debate and the underlying philosophies are clear.
Bitcoin’s “Three Kingdoms”: The Battle Between BTC, BCH, and BSV
Years ago, as Bitcoin’s block capacity neared its limit, a long and chaotic debate over scaling erupted between miners, developers, and users. When consensus became impossible, a “hard fork” was the only remaining path.
In August 2017, BCH (Bitcoin Cash) split from BTC, increasing block size from 1MB to 8MB, claiming to be the true realization of Satoshi Nakamoto’s “Peer-to-Peer Electronic Cash System.” In November 2018, internal friction within BCH led to another split: the Bitmain-backed BCHABC (which retained the BCH name) and the nChain-backed BCHSV (now BSV).
Today, the ecosystem is a “Three Kingdoms” standoff: BTC (Digital Gold), BCH (Digital Cash), and BSV (The Global Ledger). Here is what they are fighting for and their respective outlooks.
01. The Three Contenders
BTC (Bitcoin)
The primary goal of BTC is to ensure a standard home computer can run a full node, keeping the network “decentralized” to the point of being unkillable. As long as one computer is running BTC, the network survives.
While this ensures maximum security, the 1MB “small block” limit and the rise of ASIC miners have made the dream of “home-computer mining” a relic of the past. In late 2017, transaction fees soared to dozens of dollars, and some transfers took weeks to confirm. Consequently, BTC pivoted away from being a daily currency toward becoming “Digital Gold”—a store of value that is “prestigious but hard to move.” The Lightning Network is BTC’s current hope for scaling, though it remains in its early stages of merchant adoption.
BCH (Bitcoin Cash)
BCH’s philosophy is to revive the “Electronic Cash” title of the original whitepaper. Its supporters argue that BTC’s capacity simply cannot handle the transaction volume required for a global payment system.
BCH is more “flexible” (or perhaps less ideologically rigid) than its rivals. It rejects BTC’s 1MB cap but doesn’t go for BSV’s “infinite” scaling. Its logic is: Scale when needed. While it has experimented with smart contracts (via Wormhole or Copernicus), those projects saw limited success. Recently, BCH has refocused on being a pure medium of exchange.
BSV (Bitcoin Satoshi Vision)
BSV’s core philosophy is “Locked Protocol + Free Market + Infinite Scaling.”
Unlike the others, BSV targets the To-B (Business) market. It aims to provide a stable, immutable global ledger for large corporations. To achieve this, it removed block size limits entirely, moving toward Gigabyte and eventually Terabyte-sized blocks. Its ultimate vision is the Metanet—an idea where the current internet becomes a “sidechain” of BSV. It aims to be “The One Chain to Rule Them All,” combining the functions of BTC, Ethereum, and IPFS.
02. The Root of the Conflict: What is “Value”?
The deepest divide lies in where the value of Bitcoin actually comes from.
• BTC & BCH: They view Bitcoin primarily as Money. Whether as a store of value (BTC) or a medium of exchange (BCH), its value comes from a decade of consensus and its “unkillable” nature.
• BSV: They argue that nothing becomes money just by being “scarce.” In history, things (like gold) had utility first, and then became money. BSV believes Bitcoin is the “wheel,” but the Global Ledger (Metanet) is the “car.” Bitcoin is merely the fuel (utility) for that ledger. Once the ledger provides value to the world’s data, the currency used to power it naturally gains value.
Furthermore, BSV embraces regulation. Unlike the “cypherpunk” or “anarchist” roots of BTC, BSV advocates for a world where “Code is Code, and Law is Law.” They believe the blockchain should be a transparent tool for legal commerce rather than a shield for “dark web” transactions.
03. The Survival Game: The “Halving” Clock
In the next 5 to 10 years, the current standoff will likely break. The reason lies in a famous quote from Satoshi Nakamoto:
“In a few decades when the reward gets too small, the transaction fee will become the main compensation for nodes. I’m sure that in 20 years there will either be very large transaction volume or no volume at all.”
As block rewards continue to halve, miners will eventually rely solely on transaction fees. Since all three use the SHA-256 algorithm, they are competing for the same pool of computing power (hashrate).
The Winning Conditions:
1. BTC:
• Advantage: Massive brand recognition and institutional “Digital Gold” status.
• The “Win” Factor: It must either maintain an incredibly high price to keep miners profitable or achieve mass adoption of the Lightning Network to generate enough on-chain fees.
2. BCH:
• Advantage: Strong support from mining giants like Bitmain.
• The “Win” Factor: It must prove it is a better “user experience” than the Lightning Network. If merchants don’t adopt BCH, its “Digital Cash” utility vanishes, and it won’t generate enough fees to sustain the network after the block rewards disappear.
3. BSV:
• Advantage: A massive portfolio of blockchain patents and a focus on enterprise applications.
• The “Win” Factor: It is not just competing with Bitcoin; it is competing with Ethereum, Cosmos, and Solana. Its success depends on whether big businesses choose its UTXO-based model over the Account-based models of other smart-contract platforms.
Summary: BTC is betting on scarcity, BCH is betting on payments, and BSV is betting on data. In the long run, only the chain that generates enough economic activity to pay its “security guards” (miners) will survive.
