Cryptocurrencies

Bitcoin (abbreviation: BTC; sign: ₿) is the first decentralized cryptocurrency. Based on a free-market ideology, bitcoin was invented in 2008 when an unknown person published a white paper under the pseudonym of Satoshi Nakamoto. Use of bitcoin as a currency began in 2009, with the release of its open-source implementation. From 2021 to 2025, El Salvador adopted it as legal tender currency before revoking it. As bitcoin is pseudonymous, its use by criminals has attracted the attention of regulators, leading to its ban by several countries.

A blockchain is a distributed ledger with growing lists of records (blocks) that are securely linked together via cryptographic hashes. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree, where data nodes are represented by leaves). Since each block contains information about the previous block, they effectively form a chain (viz. linked list data structure), with each additional block linking to the ones before it. Consequently, blockchain transactions are resistant to alteration because, once recorded, the

Monero (; abbreviation: XMR) is a blockchain-based cryptocurrency which is private, untraceable, fungible, and decentralized.

Dogecoin features the face of Kabosu from the "doge" meme as its logo and namesake. It was introduced on December 6, 2013, and quickly developed its own online community, reaching

Cryptojacking is the act of exploiting a computer to mine cryptocurrencies, often through websites, against the user's will or while the user is unaware. One notable piece of software used for cryptojacking was Coinhive, which was used in over two-thirds of cryptojacks before its March 2019 shutdown. The cryptocurrencies mined the most often are privacy coins—coins with hidden transaction histories—such as Monero and Zcash.

Cryptoeconomics is an evolving economic paradigm for a cross-disciplinary approach to the study of digital economies and decentralized finance (DeFi) applications. Cryptoeconomics integrates concepts and principles from traditional economics, cryptography, computer science, and game theory disciplines. Just as traditional economics provides a theoretical foundation for traditional financial (a.k.a., Centralized Finance or CeFi) services, cryptoeconomics provides a theoretical foundation for DeFi services bought and sold via fiat cryptocurrencies, and executed by smart contracts.
