一文读懂DeFi衍生品市场六大方向及底层发展逻辑

全球市场将通过混合型智能合约无缝交互。

一文读懂Web3去中心化电子协议EthSign

3 月 9 日,Web3 基础设施初创公司 EthSign 宣布完成 1200 万美元种子轮融资,红杉资本、红杉印度、红杉中国均参与本轮融资,本轮融资由红杉印度和 Mirana Ventures 领投,Amber Group、Circle Ventures、NGC Ventures、HashKey Group 和 Matrixport 等参投。天使投资人包括 The Graph 业务负责人 Tegan Kline、Polygon 联合创始人 Sandeep Nailwal 等。EthSign 联合创始人 Potter Li 表示,本轮融资资金通过一个简单的协议筹集,用于未来代币( SAFT )销售。

EthSign 类似去中心化版本的 DocuSign,它允许用户以电子方式签署和管理协议。用户可以通过 MetaMask 等加密钱包登录 EthSign,上传文件并进行电子签名。

什么是EthSign?

现阶段,EthSign 3.0(PDF 签名)是一个完全无服务器的网站(http://ethsign.xyz),静态托管在 IPFS + Arweave 上,完全在用户的浏览器中运行。提供与 Web 2.0 电子协议签署平台相同的功能和用户体验,同时利用区块链的力量来提高透明度和安全性。根据路线图,EthSign 4.0测试版计划于今年第二季度推出。

EthSign 智能协议 (一文读懂DeFi衍生品市场六大方向及底层发展逻辑 ESA)是即将推出的可定制和可扩展的框架,它真正实现了“智能合约”的愿景。ESA 通过在现有法律强制执行之外或代替现有法律强制执行的情况下使用智能合约强制执行电子协议,从而使电子协议具有更严格的约束力。由 Chainlink 预言机和 Keepers 提供支持,ESA 的一个用例是由链上和/或链下条件触发的智能托管。ESA预计将于今年第三季度正式推出。

私钥管理

EthSign 允许用户使用不同的钱包登录,以便用户可以与现有的 DID 签署协议。但是如果我没有加密钱包怎么办?别担心,EthSign 还支持 Torus 和 Fortmatic 等平台,允许用户从现有身份(如电子邮件、Google 帐户、Twitter 帐户)生成私钥。

身份管理

EthSign 集成了以太坊名称服务 (ENS),使用户能够通过他们的 .eth 人类可读名称轻松地与 EthSign 交互

ENS 上的所有.eth 名称都是符合 ERC721的 NFT,用户可以更改地址、设置头像、添加其他联系人、在 ENS NFT 的元数据中定义子域。

智能合约平台

消除所有集中式服务器问题,EthSign 使用所有 EVM 兼容的区块链作为公共云。我们目前部署在 Ethereum、Polygon、Binance Smart Chain、Fantom、Moonbeam 和 Avalanche。

分布式存储

EthSign 将文件加密并存储到去信任的分布式网络中,支持 Filecoin、IPFS、Sia和 Arweave(默认)以及更多去中心化文件存储网络,EthSign 让用户能够根据自己的喜好选择哪个去中心化存储网络。

团队主要成员

项目由Jack Xu、Potter Li、Xin Yan联合创立。三位主要创始人员有丰富的区块链开发/投资经验。

Jack Xu,以太坊全栈开发人员,拥有丰富的 Solidity 经验。此前曾在通用汽车和富达投资等公司担任软件工程师。精通 Solidity、Swift、JavaScript、C++ 和 Java。南加州大学区块链辅修课程和各种计算机科学专业课程的助教。

Potter 一文读懂DeFi衍生品市场六大方向及底层发展逻辑 Li,Fundamental Labs 的前投资分析师,[email protected] 总裁,南加州大学首屈一指的学生运营的区块链组织,专注于教育、社区倡议和职业发展。

Xin Yan,Fundamental Labs 和火币集团的前高级投资经理和区块链工程师。专注于链上数据分析和智能合约设计。Xin Yan在 Web3 技术堆栈的底层基础架构方面拥有丰富的经验。

EthSign共有两轮融资历史,迄今为止的融资总资金达到 1265 万美元。

Chainlink的去中心化服务套件

Chainlink Open-source Standard

Chainlink的去中心化服务套件可以加速加密事实成为全球标准。

Chainlink Price Feeds

Chainlink Price Feeds

Chainlink Price Feeds目前覆盖了智能合约经济中大多数顶尖应用。

Chainlink Price Feeds通过一次函数调用就可以将智能合约接入最新的资产价格,并且可以以最快的速度将智能合约接入链下金融市场的各种资产数据,包括加密货币、稳定比、大宗商品、外汇和指数等。

Chainlink Price Feeds采用了安全的系统设计理念,比如多层数据聚合,多年来反复经受市场考验,包括闪电贷攻击、区块链网络拥堵等各种异常事件。Chainlink Price Feeds推动了DeFi发展到如今的规模。包括Aave、Compound和Synthetix在内的众多顶尖DeFi应用都通过Chainlink预言机可靠地接入外部喂价数据。

Chainlink储备金证明

Chainlink Proof of Reserve

Chainlink储备金证明可以实现可靠的自动化链上审计。

Chainlink VRF(可验证随机函数)

Chainlink VRF

Chainlink VRF生成了可验证的链上随机数,可以实现更公平透明的游戏体验。

Chainlink 一文读懂DeFi衍生品市场六大方向及底层发展逻辑 VRF是公平可验证的链上随机数来源,专门为智能合约应用所开发。开发者可以将Chainlink VRF作为防篡改的随机数生成器,用来创建动态NFT、公平的奖励池、治理机制或其他需要随机性的应用。

Chainlink VRF将区块数据(注:当请求发起时区块数据未知)与预言机节点预先提交的私钥结合,生成随机数以及加密证明。任何预言机节点、开发团队或外部方都无法篡改生成的加密证明。在本文截稿前,Chainlink VRF每月处理超过20万个随机数请求。

Chainlink Keepers

Chainlink Keepers

Chainlink Keepers为智能合约提供了安全的去中心化链下计算能力。

Chainlink Keepers是一个去中心化的交易自动化解决方案,为执行关键计算和DevOps操作提供了可靠方案。智能合约往往无法独自完成清算和限价单交易等计算和操作,而是需要采用去中心化且信任最小化的可靠模式代为完成。Chainlink Keepers采用了低成本且可验证的链下计算,以及受到经济激励的可靠节点网络,为用户提供去中心化的交易自动化服务。

Chainlink Keepers让智能合约可以执行某些计算操作,这些计算往往由于能力、成本和隐私等原因无法在链上直接执行。开发者无需亲自打造基础架构,而是可以将链下计算任务委托出去,并同时保障链下计算的去中心化水平和信任最小化保障与区块链保持同步。高级混合型智能合约的长期愿景是将部分代码放在一个Chainlink Keeper网络中执行,这个网络专门为智能合约而建立,并且只会在其中运行该智能合约的代码。

Chainlink Keepers and Smart Contract Security

Chainlink Keepers让开发者可以可靠、安全地将各个智能合约功能自动化。

跨链互操作性协议(CCIP)

Cross-chain Universe

跨链互操作性协议(CCIP)的目的是在数百个公链和联盟链网络之间打造通用的连接桥梁。

Cross-chain Tech Stack

跨链互操作性协议(CCIP)是开源技术栈的一部分,支持跨链数据和资产转移。

  • 共识和传输层——这是物理计算环境,其中Chainlink去中心化预言机网络(DON)采用升级版链下报告协议(OCR 2.0)达成共识,并保障消息协议可以持续、安全运行。
  • 消息传递层——CCIP是区块链互操作性的开源全局标准,智能合约可以采用通用的消息接口跨链发送消息和指令。
  • 跨链服务层——这一层负责打造基于CCIP的桥接工具,实现跨链通证转移和应用交互。可编程通证桥是基于CCIP打造的参考实现,开发者可以安全地跨链转移通证,并在目标链上触发可编程操作。换句话说,这些通证桥不仅可以转移通证,还可以同时发送指令。
  • 反欺诈网络层——这是一个独立的节点网络,网络中的节点与CCIP的节点无任何关联,这层网络公开透明,采用加密的去中心化手段监控、管理并规避任何关键风险。反欺诈网络监控消息传递、桥接系统以及所有CCIP和Chainlink用于跨链通信和通证转移的网络层活动,当检测到恶意行为时会自动暂停服务。
  • 应用和用户接口层:这层是跨链交互的应用和接口。部署接口无需许可,接口可以包含现有钱包、应用及平台等。

CoinMarketCap launches first crypto interest rates comparison product on site

PANews |2019-10-24 18:52

CoinMarketCap aims to democratize information related to interest rates, making it easy to find venues for earning and borrowing cryptoassets

NEW YORK, OCT 17, 2019 – CoinMarketCap , the world’s most used cryptocurrency information resource for cryptoassets and crypto exchanges, is announcing an entirely new addition to their site today. The new product, Interest by CoinMarketCap , ranks the most popular platforms for depositing and borrowing cryptoassets according to their interest rates.

Interest by CoinMarketCap is launching with 33 cryptoassets. Each cryptoasset is listed together with wallets, exchanges and decentralized finance platforms that provide interest products on that cryptoasset. Users can find corresponding annualized 一文读懂DeFi衍生品市场六大方向及底层发展逻辑 interest rates, minimum duration for deposit before realizing returns, start times of deposit offerings, as well as a description of each platform and its offerings.

“We are excited by the growing interest (pun intended) globally in the uses of cryptocurrencies beyond trading or holding them,” said Carylyne Chan, Chief Strategy Officer of CoinMarketCap, “With this product, we hope to create a one-stop resource for users to find out where to save, earn, borrow and margin-trade with their cryptocurrencies.”

In traditional finance, users deposit their money into banks in exchange for earning interest, and the banks in turn loan the funds to others and charge an interest for borrowing. This demand for funds from borrowers creates the opportunity for users to gain interest using the assets they own.

Likewise, in the cryptocurrency industry, there has been a rise of platforms that allow users to deposit their 一文读懂DeFi衍生品市场六大方向及底层发展逻辑 cryptoassets for a fixed period of time. The platforms go on to loan the deposited cryptoassets to companies and users who may use it for margin trading, hedging, or as working capital.

Additionally, Interest by CoinMarketCap includes Decentralized Finance (DeFi) platforms, where the platforms have no direct control over the assets deposited or loaned, and operates everything via smart contracts on the blockchain. This alleviates the centralized concerns around other platforms, but has the drawback of volatility in its interest rates. With the Interest product, CoinMarketCap hopes to provide more exposure to DeFi platforms, and make it simple for users to keep an eye on changes in interest rates on various DeFi platforms.

Against a backdrop of crypto financial applications and increasing trading activity in derivatives, CoinMarketCap believes that this product will address the interest of its users for quick information about interest rates. CoinMarketCap will continue to add useful features and details, such as each platform’s insurance scheme, licensing, regulatory environment, and more.

CoinMarketCap will also be launching more new products at its inaugural conference, The Capital, in Singapore on November 12-13.

During embargo time, you may take an early look at Interest here: https://beta-rates.coinmarketcap.com
