比特幣是一個點對點的電子現金系統，旨在通過快速支付、小額費用、隱私和高交易能力（大交易能力）成為健全的全球貨幣。就像實物貨幣，比如一張美元鈔票，被直接傳遞給被支付的人一樣，比特幣的現金支付也直接從一個人發送給另一個人。作為一種去中心化的加密貨幣，比特幣現金不需要可信的第三方，也不需要中央銀行。與傳統的法定貨幣不同，比特幣現金並不依賴於銀行和支付處理器等貨幣中間商。政府或其他中央集公司不能審查交易。同樣，資金也不能被沒收或凍結——因為金融第三方無法控製比特幣現金網絡。

以太坊經典幣(ETC)是2016年7月推出的以太坊(ETH)的一個硬幣分支。它的主要功能是作為一個智能契約網絡，能夠托管和支持分散的應用程序(DApps)。自推出以來，以太坊經典一直試圖區別於以太坊，隨著時間的推移，這兩個網絡的技術路線圖彼此之間的距離越來越遠。在一次重大的黑客事件導致360萬的ETH被盜竊後，以太坊經典首先著手保護現有的以太坊區塊鏈的完整性。

比特幣是一種去中心化的加密貨幣，最初在2008年的一份白皮書中，由一個人或一群人使用化名中本聰來描述。不久之後，它於2009年1月推出。比特幣是一種點對點的在線貨幣，這意味著所有交易都直接發生在平等獨立的網絡參與者之間，不需要任何中介允許或便利他們。根據中本聰自己的話，比特幣的創建是為了允許「在線支付可以從一方直接發送到另一方，而無需通過金融機構。在BTC之前有一些類似的概念，但比特幣是第一個實際使用的加密貨幣。

Tezos is a blockchain network that’s based on smart contracts, in a way that’s not too dissimilar to Ethereum. However, there’s a big difference: Tezos aims to offer infrastructure that is more advanced — meaning it can evolve and improve over time without there ever being a danger of a hard fork. This is something that both Bitcoin and Ethereum have suffered since they were created. People who hold XTZ can vote on proposals for protocol upgrades that have been put forward by Tezos developers.This open-source platform bills itself as “secure, upgradable and built to last” — and says its smart contract language provides the accuracy that is required for high-value use cases. According to Tezos, its approach means that it is futureproof and will “remain state-of-the-art long into the future,” meaning it can embrace developments in blockchain technology.The technology underpinning Tezos was first proposed in a white paper that was released in September 2014. After a series of delays, the Tezos mainnet launched four years later.

Uniswap is a popular decentralized trading protocol, known for its role in facilitating automated trading of decentralized finance (DeFi) tokens.An example of an automated market maker (AMM), Uniswap launched in November 2018, but has gained considerable popularity this year thanks to the DeFi phenomenon and associated surge in token trading.Uniswap aims to keep token trading automated and completely open to anyone who holds tokens, while improving the efficiency of trading versus that on traditional exchanges.Uniswap creates more efficiency by solving liquidity issues with automated solutions, avoiding the problems which plagued the first decentralized exchanges.In September 2020, Uniswap went a step further by creating and awarding its own governance token, UNI, to past users of the protocol. This added both profitability potential and the ability for users to shape its future — an attractive aspect of decentralized entities.

Ethereum is a decentralized open-source blockchain system that features its own cryptocurrency, Ether. ETH works as a platform for numerous other cryptocurrencies, as well as for the execution of decentralized smart contracts.Ethereum was first described in a 2013 whitepaper by Vitalik Buterin. Buterin, along with other co-founders, secured funding for the project in an online public crowd sale in the summer of 2014. The project team managed to raise $18.3 million in Bitcoin, and Ethereum’s price in the Initial Coin Offering (ICO) was $0.311, with over 60 million Ether sold. Taking Ethereum’s price now, this puts the return on investment (ROI) at an annualized rate of over 270%, essentially almost quadrupling your investment every year since the summer of 2014.The Ethereum Foundation officially launched the blockchain on July 30, 2015, under the prototype codenamed “Frontier.” Since then, there has been several network updates — “Constantinople” on Feb. 28, 2019, “Istanbul” on Dec. 8, 2019, “Muir Glacier” on Jan. 2, 2020, “Berlin” on April 14, 2021, and most recently on Aug. 5, 2021, the “London” hard fork.Ethereum’s own purported goal is to become a global platform for decentralized applications, allowing users from all over the world to write and run software that is resistant to censorship, downtime and fraud.

Enjin Coin is a project of Enjin, a company that provides an ecosystem of interconnected, blockchain-based gaming products. Enjin's flagship offering is the Enjin Network, a social gaming platform through which users can create websites and clans, chat, and host virtual item stores.Enjin allows game developers to tokenize in-game items on the Ethereum blockchain. It uses Enjin Coin, an ERC-20 token, to back the digital assets issued using its platform, meaning that items can be bought, sold and traded with real-world value.Enjin Coin was first announced in July 2017, and it launched on the Ethereum mainnet in June 2018.

Decentraland (MANA) defines itself as a virtual reality platform powered by the Ethereum blockchain that allows users to create, experience, and monetize content and applications.In this virtual world, users purchase plots of land that they can later navigate, build upon and monetize.Decentraland was launched following a $24 million initial coin offering (ICO) that was conducted in 2017. The virtual world launched its closed beta in 2019 and opened to the public in February 2020. Since then, users have created a wide range of experiences on their parcels of LAND, including interactive games, sprawling 3D scenes and a variety of other interactive experiences.Decentraland uses two tokens: MANA and LAND. MANA is an ERC-20 token that must be burned to acquire non-fungible ERC-721 LAND tokens. MANA tokens can also be used to pay for a range of avatars, wearables, names, and more on the Decentraland marketplace.
