2. 基本介绍:

由于区块链没办法获取外部信息,只能依靠预言机得到信息,所以区块链发展愈好,对预言机需求愈大, Band通过创建预言机平台以解决加密货币的“预言机问题(Oracle)”,该平台通过去中心化方式将其现实世界数据反馈给加密货币区块链上的 Dapps 和智能合约。

Band 项目在2019年二月份收到了由红杉印度领投的一轮种子轮融资,其中还包含了 币安,红杉印度等知名投资者。而这个项目也是红杉印度在区块链领域进行的唯一一个投资。

3. Band 技术特点

i.       融合 Web 2.0和Web 3.0

Web 2.0是「用户生成内容」由互联网单一实体(即单一互联网企业)控制的现状,由Google, 彭博等科技和媒体巨头搜集人们数据,如个人的搜索偏好记录、个人在网上的各种行为分析的数据等等。然后巨头们都建立了关于每个用户的认知文文件, 但是人们作为数据真正的主人却拿不到应属于自己的数据管理权和使用权,不能决定自己数据怎么用,而且没法获得数据带来的收入,用户数据安全、隐私、数据价值都广受威胁与忽视。

Web 3.0体系的设计使用户数据通过区块链平台改造后,使用权和管理权都将归属将于用户本身。简单来说,Web 3.0互联网的发展进入一个以用户为中心的基于区块链技术信任的网络。这意味着用户能够真正自己决定数据怎么用,比如用户可以自己授权某个机构或者公司使用自己的数据,但同时被授权方依赖数据创造的价值必须分配给相当一部分给数据的主人。

Web 3.0是未来的趋势, Web3.0的核心技术栈主要组件有:去中心化应用浏览器(Dapp Browser)、应用托管(Application Hosting)、查询图层(Query Layer)、状态转换机(State Transition Machine)、共识(Consensus)、对等网络层(P2P Layer)。其中查询层(Query Layer)代表项目为Chainlink和Band Protocol, Band Protocol为Web 3.0应用程序提供了一个安全的,与区块链无关的分布式预言机框架。

另外Band Protocol以 Layer 2 的形式为公链扩容。它允许去中心化应用将互联网上的现有数据进行利用,而无需可信任的中介。可以将API接口和现实世界的数据汇总连接到加密货币区块链上的Dapp和智能合约中。这意味Band在Web 2.0和Web 3.0的用例间架起一座桥梁。

而目前是最容易实现Web 3.0是dApp (去中心化应用)。dApp完全依靠智能合约自动运行,dApp可以在多方面应用,比如赌博的dApp, 在设计赌博游戏时,比如21点,开发者可以设计当玩家手牌大于庄家,而且少于22点时,玩家自动获得货币,反之失去货币。dApp的特色是不依赖任何中心化的服务器运作,可以全自动的运行,因此普通人士都可以开发dApp,而不需要支持高昂的服务器费用。因此dApp是推动Web3.0的重要引擎,而Band可以完全支持Web 2.0和Web 3.0的应用程序。

ii.     Band对应多条公链

Band Protocol的目标不只是帮助每一条链的开发者更容易的调用数据,更要去满足了整个区块链的生态系对于链下数据的需求,在调用可信数据时,现有预言机,如Chainlink,的作法是使用该预言机的代币来作为调用的手续费,而 Band 改善了这方面的体验,不论是对于开发者或是使用者,Band 将深度的与各大公链合作,部署可以使用该公链原生代币的预言机,举个例子来说,可以使用 ETH 来作为调用可信数据的手续费。并且在各种数据类型上面都进行了多项尝试,譬如说运动赛事的数据,金融数据,甚至是新闻信息的数据(CoinHatcher),都放入了开发者的文档让所有人可以在测试网上使用。

iii.    与多方合作

A.    Band Protocol 2021年4月 公告,宣布和 Google Cloud 达成直接合作,目前已将预言机系统整合到 Google BigQuery 上运行,可以立即,准确地分析财务时间序列数据。借助Band Protocol,Oracle数据可实时存储在Google Cloud Public Data上;可以构建传统的混合区块炼和云应用程序,以利用分散的oracle服务的独特数据馈送。使研究人员和开发人员能够将分散的oracle用于任何外部数据源或类型,而不管该应用程序是本机构建在区块链还是Web 2上。

B.    Finage与Band协议建立战略合作伙伴关系,为BandChain提供60,000多种资产的企业级市场数据,  Finage是领先的股票、外汇和加密货币企业级数据提供商Finage 为超过 17,500+的开发者、量化师、企业、大学、外汇公司和个人提供股票、外汇汇率和加密货币交易对的市场数据。其广泛的数据产品可以查询实时和历史数据集,如收盘价格、历史收盘数据、历史订单簿(L1 和 L2)、汇总、市场状态更新等,从而增加了 Band Protocol 预言机的产品和灵活性。

4. 持仓比例

A.    Band Protocol 2021年4月 公告,宣布和 Google Cloud 达成直接合作,目前已将预言机系统整合到 Google B截至5月4日,前10名大户持币占88.73%,前100名大户持币占98.58%,持币量集中,4月5日至5月4日,前10名大户持币减少, 一般用户增加, 流通量渐渐增加。于4月15日宣布与Google Cloud 达成直接合作,当天收盘上升18.75%。

I ain’t saying your content isn’t good.ain’t saying your content isn’t gooddon’t want to tell you how to run your blog, but what if you added a titleheadlinetitle that grabbed a person’s attention?maybe get a person’s attention?want more? I mean %BLOG_TITLE% is a little vanilla. You could look at Yahoo’s home page and watch how they createwrite news headlines to get viewers to click. You might add a related video or a related pic or two to get readers interested about what you’ve written. Just my opinion, it might bring your postsblog a little livelier.
