Bitcoin Cash BCH
A carrier spirit with a big cargo box on its back, hauling cheap, fast payments
🎭 A quick-footed payments offshoot that split from the original Bitcoin, cheaper and faster, thanks to a wider cargo box
💬 “Same parents as ₿, same rulebook. We just couldn't agree on one thing: how big the box should be. So I packed my bags. Watch how much I can carry now! 📦💨”
- The coin that broke away from Bitcoin over one stubborn argument: block size.
- Bitcoin kept its box at 1MB. This one made it 8MB, then 32MB, chasing cheap everyday payments.
- Under the hood it's a near-twin of Bitcoin: same PoW, same SHA-256, same 21-million cap.
📖 The Story
This story isn't really about one coin. It's about a family that couldn't stop arguing. Bitcoin (₿) carried everything in a small cargo box, just 1MB wide. That was fine when only a handful of people lined up. But the crowd grew, the line stretched, and to jump ahead you had to wave a fatter fee. “Sending a coffee's worth of money shouldn't cost more than the coffee,” some of them muttered.
One camp wanted to fix this by keeping the box small and building clever side-channels on top. The other camp had a blunter idea: make the box bigger. Neither side budged. So on August 1, 2017, at block 478,558, the big-box camp walked out and started fresh. Everyone holding Bitcoin woke up with an equal pile of this new coin, BCH, sitting beside it at 1:1. Its box went straight to 8MB, then 32MB the next year. The rivalry had a name now, and a question that still annoys both sides: which one is the real Bitcoin?
Here's the twist. The breakaway coin couldn't stop arguing either. On November 15, 2018, its own family fractured over the exact same fight, “32MB is enough” against “push it to 128MB.” The 32MB side stayed Bitcoin Cash; the rest became Bitcoin SV. So this carrier learned the family lesson the hard way: the thing that made it leave home is the same thing that splintered its house.
📊 Stats
🧩 How it works
Bitcoin Cash works in almost exactly the same way as Bitcoin. The proof-of-work (PoW), where computers solve hard math problems to lock the ledger, and the SHA-256 lock used in that math, both are the same as the original. The one big difference is the size of the cargo box (the block). A bigger box can hold more transactions at once, which is meant to shorten the line and lower fees.
🌗 Light & Shadow
- Where Bitcoin keeps transactions tight in a 1MB box, this one's 32MB box means fees stay low and confirmations come fast
- It inherited Bitcoin's 21-million cap, so it can't be printed without limit (same halving roughly every four years)
- It runs the same battle-tested PoW and SHA-256 engine as the coin it left, so nothing exotic is bolted on
- Picking a fight with Bitcoin is a losing brand war: it sits far below the original in recognition and market cap, forever answering the ‘real Bitcoin’ question
- The same stubbornness that birthed it tore it apart again in 2018, a reminder that this community fractures when it disagrees
- A bigger box means a heavier ledger, so critics worry everyday computers may struggle to run a full node (the old decentralization-vs-throughput tradeoff)
🧬 Evolution Lineage
Bitcoin Cash is a child that split from Bitcoin (₿) as a hard fork on August 1, 2017. Then on November 15, 2018, Bitcoin SV (BSV) split off from Bitcoin Cash, making BCH and BSV siblings that share the same parent.
※ Bitcoin SV (BSV) isn't in the codex yet (coming soon).

❓ FAQ
- What is Bitcoin Cash?
- It's a coin that split off from Bitcoin (a hard fork) on August 1, 2017. It made the ‘block’ cargo box bigger so it could pack in more transactions at once, aiming to be a cheaper, faster ‘digital cash’.
- How is it different from Bitcoin?
- Proof-of-work (PoW), SHA-256, and the 21-million supply cap are exactly the same as Bitcoin. The biggest difference is block size. While Bitcoin's was 1MB, Bitcoin Cash started at 8MB and grew it to 32MB in 2018, so it could pack in more transactions more cheaply.
- Is Bitcoin Cash also capped at 21 million?
- Yes. Just like Bitcoin, its maximum supply is fixed at 21 million coins. It also has the same ‘halving’, roughly every four years (every 210,000 blocks) the amount of newly created coins is cut in half.
- And what is Bitcoin SV (BSV)?
- On November 15, 2018, the Bitcoin Cash camp disagreed again and split once more. The side that kept 32MB stayed Bitcoin Cash (BCH); the side that wanted to grow it to 128MB became Bitcoin SV (BSV). So BCH and BSV are ‘siblings’ that share the same parent.
