Bitcoin
Bitcoin is a decentralized digital currency that was first described in a whitepaper published in 2008. It was created to allow individuals to make online payments directly to each other without the need for a financial institution to facilitate the transaction.
The concept of a decentralized electronic currency had been proposed before, but Bitcoin was the first to be put into practical use. It was launched in January 2009 and is based on a peer-to-peer network, which means that all transactions occur directly between users without the need for an intermediary.
Ethereum
Ethereum is a decentralized, open source blockchain 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.
Ripple(XRP)
Decentralized, open-source platform that enables fast and cheap transactions of cryptocurrencies and other digital assets. It is designed to be a global payment network that allows banks and financial institutions to send and receive payments in real-time, with low fees and without the need for a central authority.
The Ripple platform includes a native cryptocurrency called XRP, which is used to facilitate transactions on the network. XRP is known for its fast transaction speeds and low fees, and it is often used as a bridge currency to facilitate cross-border payments between different currencies.
Polygon (Matic)
Ethereum is a decentralized, open source blockchain 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.
Avalanche
Avalanche is a decentralized, open-source blockchain platform that is designed to be fast, secure, and scalable. It is built on a new consensus protocol called Avalanche, which is based on a novel concept called "sub chains" that allows for high levels of parallelization and enables the platform to process thousands of transactions per second. Avalanche also has a number of other features that make it well-suited for a variety of applications, including low transaction fees, fast finality times, and support for smart contracts. The platform is still relatively new and is actively being developed by a team of researchers and developers.
Dogecoin
Like other cryptocurrencies, Dogecoin is based on a decentralized network of computers that use cryptography to secure transactions and control the creation of new units. Dogecoin can be used to send money online, and it is often used for small transactions or as a tip or reward for content creators on social media platforms. Dogecoin has a high inflation rate and a large supply, which makes it less suitable for use as a store of value compared to other cryptocurrencies such as Bitcoin.
ADA
ADA is the native cryptocurrency of the Cardano blockchain, which is a decentralized, open-source platform for building and running smart contracts and decentralized applications (DApps).
Cardano was developed by the blockchain development firm Input Output Hong Kong (IOHK) and the Cardano Foundation, and it is designed to be a more secure and scalable platform than previous generations of blockchain technology.
ADA is used as a means of exchange on the Cardano network and can be used to send and receive value, as well as to participate in the governance of the network by staking ADA and voting on protocol updates. The total supply of ADA is capped at 45 billion coins, and the cryptocurrency is notable for its use of a proof-of-stake consensus algorithm, which is designed to be more energy-efficient than the proof-of-work algorithm used by Bitcoin and other cryptocurrencies.
Uniswap
users to buy and sell a wide range of cryptocurrencies in a trustless, decentralized manner. It is one of the leading DEXs in terms of trading volume and user adoption, and it is known for its ease of use and fast transaction speeds.
Uniswap uses a unique liquidity pool model to facilitate trades. When users want to buy or sell a cryptocurrency, they can do so directly with the liquidity pool, which consists of a mix of the two cryptocurrencies being traded. The price of the trade is determined by a mathematical formula that takes into account the supply and demand of the cryptocurrencies in the pool. This allows Uniswap to provide users with a fast and efficient way to buy and sell cryptocurrencies without the need for an order book or matching engine. Uniswap is a non-custodial exchange, which means that users are always in control of their own funds and do not need to trust a third party to hold or manage their assets.
