The Bitcoin Enigma
The provided text is from bitcoin.org and a Wikipedia entry on Satoshi Nakamoto, the pseudonymous creator of Bitcoin. It details Nakamoto's development of Bitcoin, including the creation of the blockchain and the release of the Bitcoin software. The entry extensively explores the speculation surrounding Nakamoto's true identity, listing numerous potential candidates and examining the evidence for and against each. Finally, it briefly mentions Nakamoto's impact on popular culture and provides references and external links for further information.

Satoshi Nakamoto and the Bitcoin White Paper: A Study Guide
What is Satoshi Nakamoto's primary contribution to the world?
Nakamoto is credited with inventing Bitcoin, the first decentralized cryptocurrency, and implementing the blockchain technology that underpins it. The creation of Bitcoin offered a novel approach to digital currency, bypassing traditional financial institutions.
Briefly explain the problem of "double-spending" in digital currency and how Nakamoto's system addresses it.
Double-spending is the risk of using the same digital currency more than once. Nakamoto's system solves this through a peer-to-peer network that uses a public ledger (the blockchain) to track all transactions, ensuring that each coin is only spent once.
Describe the role of "proof-of-work" in the Bitcoin network.
Proof-of-work is a computational challenge that requires miners to solve complex problems to add new blocks of transactions to the blockchain. This process secures the network by making it extremely difficult for malicious actors to alter or counterfeit transactions and incentivizes participation.
What is the significance of the "genesis block" in Bitcoin?
The genesis block is the first block in the Bitcoin blockchain, marking the inception of the network. It contained a message referring to a newspaper headline about bank bailouts, interpreted as commentary on traditional financial systems and also served as a timestamp.
Why is Nakamoto's identity a subject of speculation, and what clues have led to various theories?
Nakamoto’s identity has remained a mystery, fueling endless speculation. Clues such as writing style, computer code comments, and language use have led people to hypothesize that Nakamoto was of British, U.S. or European descent instead of the Japanese man he claimed to be.
Who is Hal Finney, and how is he connected to Bitcoin and the mystery of Nakamoto's identity?
Hal Finney was a cryptographic pioneer and the first person to use Bitcoin after Nakamoto. He received the first Bitcoin transaction and was speculated to be Nakamoto, due to his involvement, proximity to a man named Dorian Nakamoto, and stylistic similarities between his and Nakamoto's writings.
What was Newsweek's controversial claim about Dorian Nakamoto in 2014?
In 2014, Newsweek identified Dorian Prentice Satoshi Nakamoto, a Japanese-American man, as the creator of Bitcoin. However, he vehemently denied the claim, which was later backed up by a message posted by the pseudonymous Satoshi on the P2P Foundation account.
Explain the significance of the UK High Court's ruling in the case involving Craig Wright in 2024.
In 2024, the UK High Court ruled definitively that Craig Wright was not Satoshi Nakamoto, citing that he was not the author of the white paper, nor did he create or operate under the Nakamoto pseudonym. The court further accused Wright of forging documents and lying to the court extensively and repeatedly.
What does the Bitcoin white paper propose for electronic transactions?
The Bitcoin white paper proposes a peer-to-peer electronic cash system that does not rely on trust or a third party. It suggests that cryptographic proofs and a blockchain timestamp system can allow for direct transactions between parties.
According to the white paper, how is privacy maintained in the Bitcoin system?
The white paper explains that privacy in the Bitcoin system is maintained by keeping public keys anonymous. Transactions are public, but the identities of the parties involved are not directly linked, similar to the data released by stock exchanges.

Glossary of Key Terms
Bitcoin: A decentralized digital currency based on blockchain technology that allows peer-to-peer transactions without intermediaries.
Blockchain: A public, distributed, and immutable ledger that records all Bitcoin transactions in a series of blocks linked together by cryptography.
Cryptocurrency: A digital or virtual currency that uses cryptography for security, operating independently of a central bank.
Decentralization: The absence of central control or authority, with power distributed among many participants.
Digital Signatures: A mathematical scheme for demonstrating the authenticity of a digital message or document.
Double-Spending: The potential for a digital currency to be spent more than once, which Bitcoin's blockchain is designed to prevent.
Genesis Block: The first block in the Bitcoin blockchain, marking its launch.
Hash: A cryptographic function that converts data into a fixed-size string of characters; used in blockchain to link blocks together and ensure data integrity.
Merkle Tree: A tree-like data structure where each leaf node is labeled with a hash of a data block, and each non-leaf node is labeled with the hash of the labels of its children.
Nonce: An arbitrary number used in cryptography to ensure that the same input does not produce the same output; used in Bitcoin's proof-of-work process.
Peer-to-Peer (P2P): A decentralized network where participants communicate and transact directly without a central authority.
Proof-of-Work (PoW): A mechanism in blockchain technology that requires participants to solve complex computational puzzles to validate transactions and add new blocks to the chain, securing the network.
Pseudonym: A fictitious name used by an individual for purposes such as online identity or anonymity, in this case, Satoshi Nakamoto.
SHA-256: A specific hash algorithm used in Bitcoin for proof-of-work and transaction verification.
Timestamp Server: A system that establishes when a piece of data existed, creating an auditable and immutable record of events; used in Bitcoin via the blockchain to time transactions.
Transaction Fee: A charge associated with making a transaction that serves as an incentive for miners.
White Paper: A document that provides an in-depth explanation of a project or concept, in this case Bitcoin.
