Bitcoin Whitepaper - TLDR

A newcomer-friendly summary of the original Bitcoin whitepaper. Read this first, then open the full PDF when you want the details.

TLDR

  • Bitcoin is electronic cash without a central authority.
  • Transactions are grouped into blocks and chained together.
  • Proof-of-work makes it expensive to rewrite history.
  • Nodes follow the longest valid chain as the source of truth.
  • Supply issuance is fixed and decreases over time.
  • Incentives reward miners for securing the network.

Problem

Digital payments rely on trusted intermediaries. Bitcoin removes the need for that trust.

Solution

A public ledger with proof-of-work makes double spending economically impractical.

Outcome

A decentralized, predictable monetary system that anyone can verify.
