Introduction to our commented Bitcoin source code section
Below you’ll find the main commented Bitcoin source code sections (sorted by section name and filename). Core amount.h – Defines the CAmount typedef, implements minimum and maximum valid amount range check. base58.cpp – The encoding function used for Bitcoin addresses. Base58 removes some potentially ambiguous characters from Base64 so Bitcoin addresses can be written down […]
Proof of Location (PoL) Summary [Cryptocurrency consensus mechanisms]
In a Proof of Location consensus algorithm, users’ geospatial coordinates are accounted for as proof of value. This kind of algorithm is usually employed in cryptocurrency geomining systems. In a geomining application, users earn rewards for being at a certain place at a certain time. If, for example, a company wished to gather participants for […]
bitcoind.cpp – Commented Bitcoin source code
As mentioned in the Bitcoin-Qt commented source code post, there are several approaches one can take to step into the Bitcoin source in approximately the same order as it runs. For instance, tests are a great source of tiny example programs. Then there’s the ubiquitous Bitcoin-Qt client and, of course, bitcoind. All are good options […]
ELI5 PSBT – Partially Signed Bitcoin Transactions
Trustless operation is one of the key concepts behind cryptocurrencies. The idea is that you should not have to personally meet, or trust your peers, in order to perform successful transactions. Experienced crypto users may take this concept for granted, but come to think of it – every real world transaction before cryptocurrencies came about […]
Concepts In This Page
Bitcoin is the world's first viable decentralized cryptocurrency. It was released on January 2009 by Satoshi Nakamoto.
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.
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.
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.
A distributed ledger is a decentralized financial database with data stored across multiple locations.
Hal Finney was a cryptographer who pioneered the development of Bitcoin. Finney received the first ever Bitcoin transfer.
