# 302.1 Lesson - peer2Peer

**Screen:** peer2Peer

**Headline:** Peer-to-Peer Network

**Reward:** 2

**Text:** To solve the earlier mentioned issues of centralization and possible double spends, Satoshi invented a solution based on a decentralized network of nodes.

Nodes are computers that are in constant contact with each other. This by itself is nothing new. The internet itself has a similar infrastructure of interconnected nodes.

All bitcoin nodes, however, store a copy of the ledger of all transactions in the history of the Bitcoin network.

This new, decentralized form of bookkeeping, called blockchain, was first successfully implemented in Bitcoin and is extremely resistant to tampering.

## QUIZ

**Question:** Which technology did Satoshi implement to solve issues of centralization and double spends?

**Answer:** The blockchain

**Feedback:** Correct! Satoshi was the first to successfully implement the blockchain - a concept first described in 1991 by Stuart Haber and W. Scott Stornetta. It's a decentralized form of bookkeeping that is resistant to tampering and allows users to make and verify transactions without the need for a central authority

**Correct:** true

**Answer:** The internet

**Feedback:** No. The internet is a global network of interconnected computers, but it was not invented by Satoshi and does not solve issues of centralization and double spends. Try again

**Correct:** false

**Answer:** A decentralized network of nodes

**Feedback:** A decentralized network of nodes is an important part of Bitcoin, but it does not solve issues of centralization and double spends by itself. Try again!

**Correct:** false

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://earn.blink.sv/chapter-302-bitcoin-how-does-it-work/302.01-lesson-peer-2-peer.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
