The world of cryptocurrency is built upon innovation, forks, and differing visions for the future of digital money. Three major players that often cause confusion are Bitcoin (BTC), Bitcoin Cash (BCH), and Bitcoin SV (BSV). This article clarifies their origins, key differences, and core philosophies, while also exploring the unique case of Lightning Bitcoin (LBTC).
A Brief History of the Forks
The story begins with Bitcoin, the original cryptocurrency created by the pseudonymous Satoshi Nakamoto. As Bitcoin grew in popularity, a fundamental technical challenge emerged: scalability. The original 1MB block size limit began causing network congestion and higher transaction fees.
This debate on how best to scale Bitcoin led to its first major fork, creating Bitcoin Cash (BCH) on August 1, 2017. BCH increased the block size to 8MB to allow more transactions per block and keep fees low, positioning itself as "peer-to-peer electronic cash" as described in the original Bitcoin whitepaper.
However, the community behind BCH itself faced internal disagreements on its future direction. This led to a further split on November 15, 2018, resulting in two distinct chains:
- Bitcoin Cash ABC (BCH ABC): This chain continued under the BCH ticker.
- Bitcoin SV (BSV): The "SV" stands for "Satoshi Vision." This new chain, led by figures like Craig Wright, advocated for a return to what they believed was Bitcoin's original protocol and massively increased block sizes.
Key Differences Between BTC, BCH, and BSV
While all three share a common history, their paths have diverged significantly.
1. Bitcoin (BTC): The Digital Gold Standard
BTC is the original chain. Its development community prioritizes decentralization and security above all else.
- Philosophy: To be a secure, decentralized store of value—often called "digital gold."
- Scaling Solution: It implements second-layer solutions like the Lightning Network for fast, cheap micro-transactions, while keeping the main chain as a secure settlement layer.
- Block Size: Maintains a small block size (1MB segwit blocks, ~2-3MB with witness data) to ensure everyday users can run full nodes.
2. Bitcoin Cash (BCH): Peer-to-Peer Electronic Cash
BCH was born from the desire to prioritize Bitcoin's use as a medium for everyday transactions.
- Philosophy: To function as a scalable, low-fee electronic cash system for the world.
- Scaling Solution: Focuses primarily on on-chain scaling by significantly increasing the block size (now up to 32MB).
- Key Features: It includes features like simpler smart contract capabilities and has removed SegWit.
3. Bitcoin SV (BSV): The Satoshi Vision
BSV claims its goal is to restore Satoshi Nakamoto's original protocol and allow for massive enterprise-level scaling.
- Philosophy: To create a stable, massively scalable blockchain protocol that businesses can build upon, adhering to what they believe was Satoshi's original vision.
- Scaling Solution: Believes in unlimited on-chain scaling. BSV has tested and implemented extremely large block sizes (gigabytes in size) to handle vast amounts of data and transactions.
- Key Features: It aims for protocol stability and has restored certain script opcodes that were disabled in BTC and BCH.
What Is Lightning Bitcoin (LBTC)?
Lightning Bitcoin (LBTC) is another Bitcoin fork that occurred at block height 499,999. It is crucial not to confuse it with the Bitcoin Lightning Network, which is a second-layer solution for BTC.
LBTC's primary innovation is its consensus mechanism. It abandoned Bitcoin's Proof-of-Work (PoW) for a Delegated Proof-of-Stake (DPoS) model. This means:
- LBTC holders vote to elect 101 delegates to validate transactions and create new blocks.
- This system is designed to be faster and more energy-efficient than PoW, enabling higher transaction throughput.
- A key feature of LBTC is its focus on on-chain governance, allowing stakeholders to vote on protocol changes and development proposals directly.

Frequently Asked Questions
Q1: Are BCH and BSV the same as Bitcoin (BTC)?
No, they are not. While they forked from the original Bitcoin blockchain at different points in history, they are now entirely separate cryptocurrencies with their own independent networks, protocols, and development teams. They should not be considered the same as BTC.
Q2: Which one is the "real" Bitcoin?
This is a philosophical and technical debate. BTC is the original chain that has never undergone a hard fork that changed its core identity. BCH and BSV communities believe their versions better represent the original vision described in the Bitcoin whitepaper. From a market and consensus perspective, BTC (ticker: BTC) is widely recognized as Bitcoin.
Q3: What is the main goal of Bitcoin SV (BSV)?
The main goal of BSV is to create a stable and massively scalable blockchain protocol that can serve as a global enterprise data ledger and payment system. Its proponents believe this fulfills Satoshi Nakamoto's original vision for Bitcoin as outlined in the earliest versions of the software.
Q4: How does Lightning Bitcoin (LBTC) differ from the Lightning Network?
They are completely different. The Lightning Network is a Layer-2 protocol built on top of the Bitcoin (BTC) blockchain to enable fast payments. Lightning Bitcoin (LBTC) is a separate blockchain that uses a DPoS consensus model, and its name refers to its fast transaction speed, not to the Lightning Network technology.
Q5: What does "SV" stand for in Bitcoin SV?
"SV" stands for "Satoshi Vision," reflecting the project's goal to adhere to what it believes were the original intentions of Bitcoin's creator, Satoshi Nakamoto.
Q6: Is it possible for these chains to merge back together?
It is highly improbable. The forks were the result of fundamental, irreconcilable differences in technical direction and philosophy. Their codebases and communities have diverged significantly, making a reunion virtually impossible.
