Cash is physical form of a currency, such as banknotes or coins.
A ledger maintained by a centralized agency (such as a bank) that records all financial transactions.
Central Processing Unit, also known as a processor or CPU, is defined as the “brains” of the computer, coordinating different components running on a computer. CPU clock speed is measured in gigahertz or GHz for short.
The concept of centralization relates to the distribution of power and authority in an organization or a network. When a system is centralized, it means that the planning and decision-making mechanisms are concentrated at a particular point within the system.
Chain Split is another term used to describe Fork and is accordingly a situation where a blockchain splits into two separate chains. Chain Splits generally happen in the crypto world when new governance rules are built into the blockchain’s code.
Bitcoin transactions are made up of inputs and outputs, in a system called Unspent Transaction Output. When you send bitcoins, you can only send them in a whole output, and the rest are sent back as change.
A demand made by a credit-card provider for a retailer to make good on the loss on a fraudulent or disputed transaction, reversing said payment or money transfer after it was authorized.
The name given to the algorithm that encrypts and decrypts information.
The best approximation of the number of coins that are circulating in the market and in the general public’s hands.
Software that can access and process blockchain transactions on a local computer. A common application of this is a cryptocurrency software wallet.
Refers to the closing price; similar to the same term used in financial stocks.
Mining with remote processing power rented from companies operating outfits in countries like Iceland, where the electricity is abundant and cost-efficient, and the ambient temperature is cold year-round. Another term for this is mining contract.
A person or entity that has partial control and access over a cryptocurrency wallet.
Coin is a cryptocurrency or digital cash that is independent of any other blockchain or platform. The key feature of a coin is that of a currency, and the term may also be used to describe a cryptocurrency asset that is not a token.
First designed in the Bitcoin system, a coinbase is a compulsorily-included transaction on a block, the output of which directs where to send the mining reward. In the Bitcoin system, the coinbase has a 100-byte size input, where messages can be attached or used as an extra nonce.
Offline storage of cryptocurrencies, typically involving hardware non-custodial wallets, USBs, offline computers, or paper wallets
A cryptocurrency wallet that is in cold storage, i.e. not connected to the internet.
A transaction is only confirmed when it is included in a block on the blockchain, at which point it has one confirmation. Each additional block is another confirmation. Different exchanges require a different number of confirmations to consider a cryptocurrency transaction final.
Consensus is achieved when all participants of the network agree on the order and content of blocks and transactions contained in those blocks.
A privately-owned and -operated blockchain in which a consortium shares information not readily available to the public, while relying on the immutable and transparent properties of the blockchain.
A correction is a (usually negative) reverse movement of at least 10% in a cryptocurrency or general market, to adjust for over- or under-valuations.
The use of another party’s computer to mine cryptocurrency without their consent.
Cryptoassets leverage cryptography, consensus algorithms, distributed ledgers, peer-to-peer technology and/or smart contracts to function as a store of value, medium of exchange, unit of account, or decentralized application.
A cryptocurrency is a digital medium of exchange using strong cryptography to secure financial transactions, control the creation of additional units, and verify the transfer of assets.
Cryptographic hashes produce a fixed-size and unique hash value from variable-size transaction input. The SHA-256 algorithm is an example of a cryptographic hash function.
A field of study and practice to secure information, preventing third parties from reading information to which they are not privy.
Usually referring to the storage of keys, in relation to wallets or exchanges, a custodial set-up is one in which private keys are being held by the service provider while they provide a login account.
An activist who advocates for the mass adoption and use of strong cryptographic solutions and privacy-enhancing technologies to enact social and political progress.
