Bitcoin is a decentralized digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: transaction management and money issuance are carried out collectively by the network.
The original Bitcoin software by Satoshi Nakamoto was released under the MIT license. Most client software, derived or "from scratch," also use open source licensing.
Ripple provides global financial settlement solutions to enable the world to exchange value like it already exchanges information – giving rise to an Internet of Value (IoV). Ripple solutions lower the total cost of settlement by enabling banks to transact directly, instantly and with certainty of settlement. Banks around the world are partnering with Ripple to improve their cross-border payment offerings, and to join the growing, global network of financial institutions and market makers laying the foundation for the Internet of Value.
Ripple is a venture-backed startup with offices in San Francisco, New York, London, Mumbai, Sao Paulo and Sydney. As an industry advocate for the Internet of Value, Ripple sits on the Federal Reserve’s Faster Payments Task Force Steering Committee and co-chairs the W3C’s Web Payments Working Group.
Zcash is a new blockchain and cryptocurrency which allows private transactions (and generally private data) in a public blockchain. This allows businesses, consumers, and new apps to control who gets to see the details of their transactions, even while using a global, permission-less blockchain.
Zcash is a privacy-focused blockchain and cryptocurrency that was developed in response to bitcoin’s flaws. It uses the same algorithm as bitcoin but improves upon it by enabling semi-transparent processing. In simple words, this means that it eschews the radical transparency of bitcoin’s blockchain for a more nuanced implementation. In this implementation, user transaction data is revealed selectively.
Monero is the leading cryptocurrency with a focus on private and censorship-resistant transactions. Most existing cryptocurrencies, including Bitcoin and Ethereum, have transparent blockchains, meaning that transactions are openly verifiable and traceable by anyone in the world. Furthermore, sending and receiving addresses for these transactions may potentially be linkable to a person's real-world identity. Monero uses cryptography to shield sending and receiving addresses, as well as transacted amounts.
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. This enables developers to create markets, store registries of debts or promises, move funds in accordance with instructions given long in the past (like a will or a futures contract) and many other things that have not been invented yet, all without a middleman or counterparty risk.
The project was bootstrapped via an ether presale in August 2014 by fans all around the world. It is developed by the Ethereum Foundation, a Swiss non-profit, with contributions from great minds across the globe.
The mission of the Stellar Development Foundation (SDF) is to promote global financial access, literacy, and inclusion. SDF accomplishes this by expanding worldwide access to low-cost financial services through the development and maintenance of technology and partnerships.
SDF’s vision is an open and affordable financial system where people of all income levels can access simple-to-use, secure, and low cost financial services. SDF also aims to empower developers with useful technology to create financial products and services for their communities.
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.
TRON is dedicated to building the infrastructure for a truly decentralized Internet. The Tron Protocol, one of the largest blockchain-based operating systems in the world, offers scalable, high-availability, and high-throughput support that serves as the foundation for all decentralized applications in the TRON ecosystem. It also provides better compatibility for Ethereum smart contracts through an innovative, pluggable smart contract platform.
