Bitcoin

Bitcoin is a cryptocurrency and worldwide payment system. It is the first decentralized digital currency, as the system works without a central bank or single administrator. The network is peer-to-peer and transactions take place between users directly, without an intermediary. These transactions are verified by network nodes through the use of cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin was invented by an unknown person or group of people under the name Satoshi Nakamoto and released as open-source software in 2009.


Ethereum

Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. These apps run on a custom built blockchain, an enormously powerful shared global infrastructure that can move value around and represent the ownership of property.


Ripple

Ripple is a real-time gross settlement system (RTGS), currency exchange and remittance network by Ripple. Also called the Ripple Transaction Protocol (RTXP) or Ripple protocol it is built upon a distributed open source Internet protocol, consensus ledger and native cryptocurrency called XRP (ripples). Released in 2012, Ripple purports to enable "secure, instantly and nearly free global financial transactions of any size with no chargebacks." It supports tokens representing fiat currency, cryptocurrency, commodity or any other unit of value such as frequent flier miles or mobile minutes. At its core, Ripple is based around a shared, public database or ledger,[6] which uses a consensus process that allows for payments, exchanges and remittance in a distributed process.


Bitcoin Cash

The Bitcoin scalability debate led to the cryptocurrency split on August 1, 2017. A chain coming out of the split and setting its block size limit to eight megabytes to increase the number of transactions its ledger can process is called Bitcoin Cash (BCH). The rule change increasing the bitcoin block size limit of one megabyte to eight megabytes is classified as a hard fork.


Cardano

Cardano is home to the Ada cryptocurrency, which can be used to send and receive digital funds. This digital cash represents the future of money, making possible fast, direct transfers that are guaranteed to be secure through the use of cryptography.

Cardano is more than just a cryptocurrency, however, it is a technological platform that will be capable of running financial applications currently used every day by individuals, organisations and governments all around the world. The platform is being constructed in layers, which gives the system the flexibility to be more easily maintained and allow for upgrades by way of soft forks. After the settlement layer that will run Ada is complete, a separate computing layer will be built to handle smart contracts, the digital legal agreements that will underpin future commerce and business. Cardano will also run decentralised applications, or dapps, services not controlled by any single party but instead operate on a blockchain.


Litecoin

Litecoin is a peer-to-peer Internet currency that enables instant, near-zero cost payments to anyone in the world. Litecoin is an open source, global payment network that is fully decentralized without any central authorities. Mathematics secures the network and empowers individuals to control their own finances. Litecoin features faster transaction confirmation times and improved storage efficiency than the leading math-based currency. With substantial industry support, trade volume and liquidity, Litecoin is a proven medium of commerce complementary to Bitcoin.


NEM

NEM’s blockchain platform was designed and coded from the ground up for scale and speed. NEM’s permissioned private blockchain delivers industry-leading transaction rates for internal ledgers. And its revolutionary consensus mechanism and the Supernode program ensure that NEM’s open, public blockchain can grow without ever compromising throughput or stability.


Stellar

Stellar is a distributed, hybrid blockchain that is fully open-source. It is infrastructure that exists to facilitate cross-asset transfers of value, including payments. With just one integration into the Stellar Network, you will join an open, global financial network where all actors – be they people, payment networks, or banks – have equal access and economic participation.


IOTA

IOTA is an open-source distributed ledger (cryptocurrency) focused on providing secure communications and payments between machines on the Internet of Things. Using directed acyclic graph (DAG) technology instead of the traditional blockchain, IOTA's transactions are free regardless of the size of the transaction, confirmation times are fast, the number of transactions the system can handle simultaneously is unlimited, and the system can easily scale. IOTA was founded in 2015 by David Sønstebø, Sergey Ivancheglo, Dominik Schiener, and Dr. Serguei Popov.


TRON

TRON is a blockchain-based decentralized protocol that aims to construct a worldwide free content entertainment system with the blockchain and distributed storage technology. The protocol allows each user to freely publish, store and own data, and in the decentralized autonomous form, decides the distribution, subscription and push of contents and enables content creators by releasing, circulating and dealing with digital assets, thus forming a decentralized content entertainment ecosystem.
