Bitcoin and Satoshi Nakamoto Glossary

Clear definitions for the technical and historical terms used in Satoshi identity research, with special attention to what each term can—and cannot—prove.

Evidence note: the identity of Satoshi Nakamoto remains unproven. This site distinguishes documented facts from interpretation and speculation.

Bitcoin
A peer-to-peer electronic cash system and open monetary network introduced in the 2008 whitepaper published under the name Satoshi Nakamoto.
Satoshi Nakamoto
The pseudonym used by Bitcoin’s creator or creators. It does not refer to the smallest bitcoin unit in this context.
satoshi (sat)
The smallest commonly recognized unit of bitcoin: one hundred-millionth of one bitcoin. The lowercase term honors the creator’s pseudonym.
Bitcoin whitepaper
The nine-page paper describing a peer-to-peer electronic cash system that uses a chain of proof-of-work records to address double spending without a trusted financial intermediary.
Blockchain
A linked history of transaction blocks. In Bitcoin, nodes validate blocks under shared consensus rules rather than relying on a central ledger operator.
Proof of work
A mechanism requiring computational work to propose blocks. Bitcoin uses it to order transactions and make revision of the chain costly.
Genesis block
The first block in the Bitcoin blockchain, created on 3 January 2009. It is also called block zero.
Private key
A secret number used to authorize spending. Control of an early key linked convincingly to Satoshi could provide important evidence, but provenance still matters.
Digital signature
A mathematical proof that a message was authorized using a private key, verifiable with the corresponding public key.
Cypherpunk
A person or movement advocating the use of cryptography and privacy-enhancing technology to produce social and political change.
Hashcash
Adam Back’s proof-of-work anti-spam system. A version of Hashcash is cited in the Bitcoin whitepaper and influenced Bitcoin mining.
b-money
Wei Dai’s proposal for an anonymous, distributed electronic cash system. It is cited in the Bitcoin whitepaper.
Bit Gold
Nick Szabo’s proposal for digital scarcity based on computational work and linked records. It preceded Bitcoin but was not Bitcoin.
Double spending
The risk that the same digital value is spent more than once. Bitcoin’s consensus and transaction-history design addresses this without a central clearing party.
Mining
The process by which participants perform proof of work, propose valid blocks, and may receive newly issued bitcoin plus transaction fees.
Stylometry
The statistical study of writing style. It can compare vocabulary, syntax, punctuation, and other features, but results depend heavily on corpus quality and comparison design.
Patoshi pattern
A debated mining-pattern analysis used to estimate how many early blocks may have been mined by one dominant miner, sometimes attributed to Satoshi. It is an inference, not an identity label embedded in the blockchain.
Cryptographic proof
Evidence that can be verified mathematically, such as a valid signature. It can prove control of a key, but the historical ownership of that key must still be established.
