In cryptography, a certificate authority or certification authority (CA) is an entity that issues digital certificates. A digital certificate certifies the ownership of a public key by the named subject of the certificate. This allows others (relying parties) to rely upon signatures or on assertions made about the private key that corresponds to the certified public key.
Chain reorganization is a client-local phenomenon where a client discovers a new difficultywise-longest well-formed blockchain which excludes one or more blocks that the client previously thought were part of the difficultywise-longest well-formed blockchain, resulting on orphan blocks.
The change in blockchain is when the client generates a new Bitcoin address, and sends the difference back to this address. When the output of a transaction is used as the input of another transaction, it must be spent in its entirety. Sometimes the coin value of the output is higher than what the user wishes to pay. In this case, the client generates a new Bitcoin address, and sends the difference back to this address. This is known as change.
Proprietary software, also known as non-free software, is computer software for which the software's publisher or another person reserves some rights from licensees to use, modify, share modifications, or share the software.
Coin is a cryptocurrency with its own blockchain, usually created by developers from scratch or by forking. You can also find the term “altcoin”, which implies an alternative coin, that is any coin that is not Bitcoin. Bitcoin is the best example of a coin. Bitcoin is not only the world's first cryptocurrency but also the world's first blockchain.
Coin burn is a term meaning the intentional riddance of a certain number of cryptocurrency items to ensure its stable work, rate normalization or create a new cryptocurrency.
The coinbase is the content of the 'input' of a generation transaction. While regular transactions use the 'inputs' section to refer to their parent transaction outputs, a generation transaction has no parent, and creates new coins from nothing. The coinbase can contain any arbitrary data.
Cold storage in the context of Bitcoin refers to storing Bitcoins offline and spending without the private keys controlling them ever being online. This resists theft by hackers and malware, and is often a necessary security precaution especially dealing with large amounts of Bitcoin. For example, a Bitcoin exchange which offers an instant withdrawal feature, and might be a steward over hundreds of thousands of Bitcoins. To minimize the possibility that an intruder could steal the entire reserve in a security breach, the operator of the website keeps the majority of the reserve in cold storage, or in other words, not present on the web server or any other online computer. The only amount kept on the server is the amount needed to cover anticipated withdrawals in one day.
A command-line interface (CLI) processes commands to a computer program in the form of lines of text. The program which handles the interface is called a command-line interpreter or command-line processor. Operating systems implement a command-line interface in a shell for interactive access to operating system functions or services.
