Cryptography

Cryptography is the cornerstone of cryptocurrencies. Bitcoin was made possible by well known cryptographic mechanisms that were assembled by Satoshi Nakamoto in a very creative way.

Although cryptography has been in use for thousands of years, only now has it become a household name due to the popular exposure brought by cryptocurrencies.

Although the subject of highly technical mathematical studies, here we approach crypto from the end user’s perspective, using accessible language and easy to understand concepts.

SHA256 - SHA256 is an encryption routine which produces a unique and irreversible digest for a given message.
shafs
Quantum Cryptography - The field of cryptography which leverages quantum physics as its underlying computing model.
Bitcoin - Bitcoin is the world's first viable decentralized cryptocurrency. It was released on January 2009 by Satoshi Nakamoto.
Bitcoin Puzzle - A Bitcoin Puzzle is a cryptographic puzzle which carries Bitcoin as a reward. Those able to break the cryptography obtain access to the private key needed to unlock the Bitcoin.
Consensus Mechanism - A process or system by which multiple parties are able to reach consensus. In the context of cryptocurrencies, it's the process which allows for everyone to agree on everyone else's money balance. E.g. Bitcoin employs Nakamoto consensus via PoW mining.
Digital Money - A concept of value exchange that does not require physical tokens (coins or paper cash) to be used in order to trade. Cryptocurrencies are a type of digital money.
Distributed Ledger - A distributed ledger is a decentralized financial database with data stored across multiple locations.
