BTC

比特币由中本聪(化名)创立于2009年,是一个点对点的数字货币系统,致力于重建具有隐私性和自治性的支付系统来避免银行和政府这些中间人的参与。 目的是允许个人和商户可以自由的“面对面”的直接交易。

比特币虽然只是支持脚本语言,但是其脚本语言实际上也可以实现比较丰富的场景,后续我也会更新关于比特币开发的相关教程;

Bitcoin, created in 2009 by Satoshi Nakamoto, is a peer-to-peer digital currency system that endeavors to re-establish both privacy and autonomy by avoiding the banking and government middlemen. The goal is to allow individuals and merchants to generate and exchange modern money directly

Ethereum

以太坊是一个开源的公开的基于区块链的分布式计算平台和操作系统,支持智能合约, 简单来说,比特币只支持脚本语言,而以太坊是图灵完备的,意思是开发者可以像开发传统软件一样开发基于区块链的项目,所以这也是为什么以太坊拥有完整的生态和众多开发者的原因;

后续我会发布的关于区块链开发的教程基本都是以以太坊为主;

以太坊通过基于交易的状态转移实现了改良版本的中本聪共识算法;

Ethereum is an open source, public, blockchain-based distributed computing platform and operating system featuring smart contract functionality. It supports a modified version of Nakamoto consensus via transaction-based state transitions.

Zcash

什么是Zcash? What is Zcash?

Zcash是由热爱比特币的密码学专家在2016年基于比特币源码创建的,加入了零知识证明; 实际上很多人误解比特币,比特币并不是真正的匿名支付,因为你可以从支付历史上清晰的看到从哪个账号转给哪个账号多少钱,这些都是完全公开的, 另外虽然只是一串地址,但是如果参与了交易所的交易,由于KNC要求,是可以追踪到某个人的真实信息的; 而Zcash则引入了另外一种方式,通过采用密码学的方式对支付记录进行了混淆,从而可以让支付路径无法被追踪(比如你网购了某些东西但是不想让别人知道你的真实信息),当然这也是很多政府可以容忍比特币但是不喜欢Zcash的原因;

Zcash is created in 2016 by cryptography experts who love bitcoin, but wanted the option to make transacgtions more private, so they took Bitcoin’s opensource code and enhanced it with a technology known as the “Zero-Knowledge Proof” Zcash and financial privacy Zcash was created because the team behind it believes that financial privacy is a fundamental human right. Learn why financial privacy is so important and how Zcash hopes to improve it.

Zcash的隐私性是怎么工作的? How does Zcash’s privacy work?

Zcash的“屏蔽”交易可以让你跟其他人转账但是不公开隐私的交易内容。Zcash有两种地址类型shielded地址和transparent地址, transparent地址是公开的,工作方式跟比特币地址一样,shielded地址则会隐藏交易信息,这依赖于零知识证明,零知识证明是密码学的突破, 大概意思就是我可以证明我知道某些事情但是不告诉你我具体知道什么,比如我可以证明我超过了18岁,但是不告诉你我的实际年龄;

Zcash’s shielded transactions let you exchange value without revealing your private financial information.

Basic Attention Token

BAT不仅是代币,brave也是我最喜欢的浏览器,屏蔽各种广告和js追踪,由javascript之父创建的brave,内置tor,正常浏览网页还可以赚取BAT:点击官方链接

Brave的使命是修复当今“被破坏的”web服务。 Brave is on a mission to fix what it believes is a broken web.

Brave和BAT:一种新的浏览方式 Brave and BAT: A new way to browse the web

Brave认为网上冲浪应该更快,更安全,更多隐私保护,并且没有广告的暴力植入。 Brave believes that surfing the web should be faster, more secure, and more private without intrusive ads.

Brave浏览器 The Brave web browser

Brave是一个免费的开源的web浏览器,屏蔽各种广告和js追踪,内置tor,正常浏览网页还可以赚取BAT:点击官方链接 Brave is a free, open-source web browser with several unique features.

BAT注意力币是如何工作的 How the Basic Attention Token works

BAT是基于以太坊的代币,当前的广告模式是,广告商找到百度谷歌这些搜索巨头,然后分发广告给网站等内容博主,然后搜索巨头从中获取巨额利益, 普通人被广告骚扰但是没有任何收益,内容博主也被剥削,BAT通过干掉中间商,让普通网友跟内容博主直接互动,普通网友通过浏览网站就可以获取BAT代币, 因为普通人花费了时间和注意力,所以这个叫做注意力代币,然后可以打赏给内容博主; The Basic Attention Token (BAT) is an Ethereum-based token that is designed to improve digital advertising on the web.

Stellar.XLM.

Stellar是一个连接银行、支付系统和用户的平台。 Stellar is a platform that connects banks, payment systems, and people.

什么是Stellar? What is Stellar?

什么是Stellar Lumens或XLM? What are Stellar Lumens (XLM)?

Stellar网络有自己的虚拟币:Stellar Lumens或XLM,目的是帮助基于Stellar网络的低费用的统一的支付。 The Stellar network has its own cryptocurrency, the Stellar Lumen. Lumens facilitate low-cost, universal payments on Stellar.

通过Stellar汇款 Sending remittances with Stellar

对于需要跨国给家人转账的用户来说,相对于传统的转账服务,Stellar提供了更便宜更快速的选择。 For people sending money to family members overseas, Stellar offers a cheaper, faster alternative to traditional money transfer services.

银行、企业和用户怎么使用Stellar How banks, businesses, & people use Stellar

Stellar允许银行、企业和用户将传统的资产比如美元欧元转成代币,这些代币可以通过Stellar网络迅速的在其他参与者之间转移和交换。 to issue, exchange and transfer tokens quickly and efficiently; Stellar lets banks, businesses, and people turn traditional assets, like dollars and euros, into tokens. These tokens can then be transferred and exchanged with any other participant on the Stellar network.

Stellar如何保护数字资产? How does Stellar protect digital assets?

Stellar上的数字资产是通过全球的去中心化的计算机网络节点运行Stellar的开源软件来保护的。这些计算机节点通过合作来验证交易的合法性并阻止非法交易。 Stellar的共识协议是基于可信节点的协作来确认交易,这个跟比特币是不同的,比特币是通过节点之间的挖矿竞争来确认交易。 Digital assets on Stellar are protected by a decentralized global network of computers running Stellar’s open source software. These computers cooperate to confirm legitimate transactions and prevent malicious ones. Stellar’s Consensus protocol relies on the coorperation of trusted nodes to confirm transactions

EOS
