How to explain Bitcoin Whitepaper to a 8 year old kid - Part 6

Simplified Payment Verification (SPV)
Not everyone needs to carry the whole blockchain. With SPV, your phone only keeps the block headers — tiny summaries of each block. Your wallet can ask full nodes: "Whats the longest chain right now?"
How It Stays Safe
Each new block added on top makes your transaction safer. Thats why people say: "Wait for 6 confirmations before considering a Bitcoin payment final."
Combining and Splitting Value
In Bitcoin, money lives in many little coins. Each transaction takes some coins in and sends new ones out. You can combine small coins or split big ones easily — just like breaking a $100 bill into five $20s.
In short:
- 💼 SPV lets you use Bitcoin without storing everything.
- 🌳 You only need block headers and a Merkle branch.
- 🔢 Bitcoin transactions have inputs and outputs.
- 💸 You can combine small coins or split big ones easily.
