愿景 使命 目标
1、若奔雷、席卷而来。区块链作为时代的标签,自中本聪2009年提岀比特币概念以来以区块链技术为基础的加密数字资产迅速发展,总市值一度逼近万亿美元。区块并不再遥远,已经来到触手可及的眼前,它是互联网的一部分,在交通、教育、医疗、衣业、产权、支付、生活服务等领域已经岀现诸多应用场景,区块链让互联网浪潮再次升级,并逐步深入到更多的创新领域.在数字货币领域。区块链并不仅仅是一种技术创新,其背后含的去中心化、去信任化思维更揭示了构建全新经济模式的可能。在价值赋权和转移领域,区块链技术因其公开透明、可追溯、不可篡改的特点,已经开始展现出巨大的优势,最终,它将帮助我们完成资产数字化这一价值迁移,实现对自身财富的真正掌控。
2、数字资产市场目前不光包括比特币、以太坊等传统数字资产,也包含了柚子(EOS)、瑞波(XRPV)、小蚁(NEO等各类代币,而这些代币的主流发行模式为众筹。众筹即是区块链项目首次发行代币,通俗的说就是募集比持币以太坊等通用数字币的行为,众筹作为一种融资形式,具有天然的高效性、便捷性和优越性,再加上互联网的技术优势,让数字货币成功打了金融世界的空间壁垒,让资产的管理不再受语言、肤色、国界的限制区块链领过众筹项目以网上公示的形式发布白皮书,通过数字货币进行融资。投资者通过钱包和签名即可实现投资过程安全方便,更无需签署任何协议。以上便利,自然为区块链众是供了生长发育的广阔空间。
3、葫芦宝将打造涵盖所有用户与所有应用场合的公有链以及链接各个企业联盟的私有链,并利用平台自行推出的数字货币葫芦资产( Gourd Assets,以下简称GAss)打通各金融机构、数字货币发行平台与投资人之间的鸿沟,解决目前金融市场、数字货币市场、移动支付而场的众多捅氚题,是区玞链最新级架构理忿指导下的一个有宝国乃至笙球性哑用玚景和雄伟理想蓝图的区块链项目。

1、gas是个度量单位:我们生活中有衡量长短的单位-米,时间单位分钟小时和天以及年以及汽车损耗的汽油的度量单位升……有了这些作为铺垫我们就好理解以太坊中的gas啦。
2、在交易过程中对于大家来书同样一个比特币或者ether折换成人民币在同一时刻应该是相同的,对于同一个交易大家挖矿时消耗的计算力是相同的。那么怎么将每一份计算力划分出来等价于一份以太坊的资源消耗呢?对了划分度量—gas。这个gas犹如我们的金钱中的圆角分的数量是个资源对应出来的个体—买衣服花了200块钱这个那么换算成就是我买衣服花了200个ether(当然了这个衣服太贵啦…)
3、gasPrice是整个网络公认动态调整的一个代表一个gas购买力的数据。还原到现实世界的一个例子就是:有车的朋友都会关注汽油价格的波动,一个100升的油箱在汽油是2￥/V的时候你加满需要200块钱,还原至以太坊就是我执行这个预算需要消耗100的算力每个算力需要2gas,那么每个gas的价格就是50啦。当然了这100个算力是燃烧人民币换来的,假设折合1000块钱吧此时我们的gasprice就是对应人民币就是500 ￥/gas。再假如1gas就是一个以太币的话,那么1以太币的价格就是500大洋啦
4、对于矿池中的交易数据需要旷工挖矿而旷工肯定是挑挑拣拣的啦—要么容易单位算力打包的多,要么总价贵,总之就是我要挑单位收益高的来。当然了系统也是这么设定的要不然大家都不钱系统怎么运行啊。
未来哪个行业发展前景好
1、Gauss是2017年德国 Gauss Lab 发起的项目,旨在使用跨链技术解决同构或异构数字资产的对接与交流问题,提升区块链的价值,促进区块链市场的统一和发展,从而实现区块链对商业形态的改革,引导区块链产业的大爆发。
2、2020年11月,Gauss提前完成了项目计划的第一阶段——建立Gauss net的基本服务层,构建和启动Guass net 主网,发布了初始版本的Gauss网络移动客户端。
3、2020年11月之后,Gauss开始了第二阶段的技术研发。Gauss的第二阶段比第一阶段增加了更多的基本模块以支持应用开发,特别是DeFi应用。这些新的模块包括多资产管理、Gauss-swap,多签账户等。Gauss计划与1-2个生态伙伴合作,使用这些模块开发应用,并在合适的阶段将源代码进行开源(预计在8月中下旬将会完成第二阶段的部署开发)。
4、Gauss的第三阶段开发任务目前已在计划中,预计将在2021年8月到2021年的12月,专注于Gauss跨链桥和中继链技术,完成Gauss与ETH,TRON等生态网络的连接,Gauss与Cosmos网络的连接等。

数据如何上传到区块链
1、geth Ubuntu 104 安装采用源码安装:GitHub上的说明如下GitHub 官方给出的 Ubuntu 系统安装geth同时需要提前安装好go安装go的参考博客go安装仅仅在用户的环境变量中配置了,即~/.bashrc文件中本次使用的gitclone 方式配置了 /etc/hosts文件,大大提高了下载速度,不然下载go-ethereum文件夹非常慢,去ip查询网址IPAddress查询gitclone.com ip地址,配置到 /etc/hosts文件末尾:# 199
