Bitcoin White Paper Translated into Plain English

Explore how a peer-to-peer digital cash uses digital signatures and a proof-of-work blockchain to prevent double spending. Miners lock blocks to form a chain; the longest chain proves transaction order.

Explain the flaws of trust-based online payments and the need for cryptographic peer to peer system. Show how double spending is prevented with a distributed timestamp system that orders transactions.

Describe how a digital coin forms a chain of signatures using the hash of the previous transaction and the next owner's public key, enabling verification and preventing double spending.

Shows how a time stamp server creates a timestamp by hashing a group of items and publicly publishing the hash, linking each timestamp to the previous one in a chain.

Explain how proof-of-work enables a distributed time stamp system by solving for a magic number that yields a hash with zeros and locks each block with the previous hash.

Broadcast new transactions to all nodes as miners perform proof-of-work to mine blocks and validate transactions, preventing double spending, while the longest-chain rule determines the valid history.

Miners compete to add blocks, earning the coinbase reward in the first transaction and thereby securing the network through the block incentive, which later shifts to inflation-free transaction fees.

Reclaim disk space by pruning block transactions using a Merkle tree, storing only root hashes, and downloading the tree to verify the longest chain while compacting older branches.

Explore simplified payment verification, which verifies transactions using only block headers and the merkle root tied to the longest chain, while full nodes securely verify the full blockchain.

Discover how Bitcoin combines and splits value using multi-input and multi-output transactions, typically yielding a payment to the receiver and change to the sender, supporting privacy.

Explain how traditional banks protect privacy by centralizing information, while Bitcoin privacy uses anonymous public keys to show transactions without revealing owners and suggests new key pairs per transaction.

Explain how an attacker might outrun the honest bitcoin network using a binomial random walk and gambler's ruin, and how wait times reduce double-spend risk.

We propose a system for electronic transactions without trust or a third party, using a peer-to-peer network with a public history and proof of work to prevent double spending.
