CryptoKitties 背后的开发人员对以太坊感到沮丧，并着手解决他们遇到的技术问题。 在这样做的过程中，他们创建了一个新的区块链，专为他们帮助普及的应用程序而设计。 Flow 游乐场于 2020 年推出，使开发人员能够创建和交易不可替代的代币 (NFT)

Cosmos 是一个项目，旨在创建一个由开源工具联合起来的加密网络网络，以简化它们之间的交易。 这种对可定制性和互操作性的关注是 Cosmos 与其他项目的不同之处。

Polygon（Matic Network）是第一个结构良好、易于使用的以太坊扩展和基础设施开发平台。它的核心组件是Polygon SDK，这是一个模块化、灵活的框架，支持构建多种类型的应用程序。

Chiliz是同名的马耳他金融科技提供商在体育和娱乐领域领先的数字货币。它运营基于区块链的体育娱乐平台Socios，使用户能够参与他们喜爱的体育品牌的治理。 Socios.com的多个粉丝令牌就是一个例子。对于体育俱乐部和协会，粉丝代币提供了一种与粉丝联系并解锁新收入来源的方式。

比特币硬币是一个点对点的电子现金系统，旨在通过快速支付、小额费用、隐私和高交易能力（大交易能力）成为健全的全球货币。就像实物货币，比如一张美元钞票，被直接传递给被支付的人一样，比特币的现金支付也直接从一个人发送给另一个人。作为一种去中心化的加密货币，比特币现金不需要可信的第三方，也不需要中央银行。与传统的法定货币不同，比特币现金并不依赖于银行和支付处理器等货币中间商。政府或其他中央集公司不能审查交易。同样，资金也不能被没收或冻结——因为金融第三方无法控制比特币现金网络。

以太坊经典币(ETC)是2016年7月推出的以太坊(ETH)的一个硬币分支。它的主要功能是作为一个智能契约网络，能够托管和支持分散的应用程序(DApps)。

自推出以来，以太坊经典一直试图区别于以太坊，随着时间的推移，这两个网络的技术路线图彼此之间的距离越来越远。

在一次重大的黑客事件导致360万的ETH被盗窃后，以太坊经典首先着手保护现有的以太坊区块链的完整性。

比特币是一种去中心化的加密货币，最初在2008年的一份白皮书中，由一个人或一群人使用化名中本聪来描述。不久之后，它于2009年1月推出。

比特币是一种点对点的在线货币，这意味着所有交易都直接发生在平等独立的网络参与者之间，不需要任何中介允许或便利他们。根据中本聪自己的话，比特币的创建是为了允许“在线支付可以从一方直接发送到另一方，而无需通过金融机构。”

在BTC之前有一些类似的概念，但比特币是第一个实际使用的加密货币。

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.
