A cryptocurrency is a type of digital token that relies on cryptography for chaining together digital signatures of token transfers, peer-to-peer networking and decentralization. In some cases a proof-of-work scheme is used to create and manage the currency.
Cryptocurrencies allow electronic money systems to be decentralized; systems include:
- Bitcoin, the first cryptocurrency, a peer-to-peer electronic monetary system based on cryptography.
- Ethereum, an open-source, public, blockchain-based distributed computing platform featuring smart contract (scripting) functionality.
- Bitcoin Cash, a 2017 fork of bitcoin; main differences from bitcoin are larger blocks, different difficulty adjustment algorithm, and lack of Segregated Witness.
- IOTA, an open-source distributed ledger and an electronic monetary system designet for the Internet of Things. It uses a directed acyclic graph (DAG) instead of a blockchain.
- Ripple monetary system, a monetary system based on trust networks.
- Litecoin, originally based on the bitcoin protocol, intended to improve upon its alleged inefficiencies. Faster block times and different mining algorithm compared to bitcoin.
- Dash, originally based on the bitcoin protocol, it offers the option of instant and private transactions. It is a Decentralized Autonomous Organization.
- Hatch, a 2018 fork of Dash.
- NEM, a peer-to-peer electronic monetary system and a blockchain platform which allows for storing digital assets.
- NEO, an open-source, public, blockchain-based distributed computing platform featuring smart assets contract functionality.
- Monero, an open source cryptocurrency created in April 2014 that focuses on privacy, decentralisation and scalability.
- Zcash, a cryptocurrency that offers privacy and selective transparency of transactions.
- Dogecoin, a Litecoin-derived system meant by its author to reach broader demographics.
- NXT, conceived as flexible platform to build applications and financial services around.
- Zcoin, a privacy centric cryptocurrency that utilized the zerocoin protocol.
