❶ 什么是热钱包和冷钱包

热钱包是指以任何方式连入互联网的钱包。例如，在币安创建帐户并向个人钱包发送资金时，采用的就是币安的热钱包。这些钱包的设置相当简单，资金也可以快速存取，便于交易者和其他高频用户使用。

❷ 比特币冷钱包和热钱包有什么区别币包怎么样

比特币冷钱包是指用户帐号和个人密钥分开存放的一种比特币存放方式。
热钱包通常是指比特币在线钱包，用户个人帐号及密码信息全部存放在一个网络平台上面；网站平台为用户提供安全。
币包是一家专业提供比特币钱包服务的网站平台，有冷钱包和热钱包两咱存储方式；总体来说，用户评价还是不错的。

❸ 什么是冷钱包

通俗来说冷钱包就是将数字货币进行离线下储存的钱包，玩家在一台离线的钱包上面生成数字货币地址和私钥，再将其保存起来。而冷钱包是在不需要任何网络的情况下进行数字货币的储存，因此黑客是无法进入钱包获得私钥的。

❹ 数字货币钱包的分类

通俗来说区块链钱包就是用来存储数字货币的，实际上，区块链钱包存储的并不是数字货币，而是存储密钥（私钥和公钥）的工具，有了密钥就可以拥有相应地址上的数字货币的支配权，利用区块链钱包中生成的数字货币收款地址，可以接受他人给你转账的数字货币，也可以把你所拥有的数字货币转账给其他人

数字货币钱包的分类：

大体上可分为两大类，热钱包（在线钱包）和冷钱包（离线钱包）

一、热钱包

热钱包又称在线钱包，包含轻钱包和重钱包（全节点钱包），需保持连网上线的钱包，可以直接进行交易操作。

1、轻钱包：

不储存完整的区块链，只保存和自已相关的数据。它的体积小，可以在手机、电脑、网页等运行。

优缺点：不占用内存、支持多种数字资产、用户体验好、新手上手快，但交易验证稍慢

2、重钱包（全节点钱包）

维护着全部的区块链数据，完全去中心化，同步所有数据。具有更好的隐私性、可以在本地验证交易数据的有效性。

优缺点：具有更好的隐私性、验证信息更快速，但每次使用都需要前需要同步数据，占用很大的硬盘空间，不支持多种数字货币交易。

二、冷钱包

冷钱包就是不连网的钱包，也叫离线钱包；比如专业的硬件设备，或者将私钥（助记词）写在纸上。

1、硬件钱包

硬件钱包即是用专业的硬件存储数字货币，将数字资产私钥单独储存在一个芯片中，与互联网隔离，即插即用。

2、纸钱包

把私钥写在纸上存储，再删除

冷钱包的优缺点：

相对比较安全，但创建钱包和交易都非常麻烦，对于新手来说操作比较困难，钱包价格都相对昂贵，一般从几千到上万元不等。如果没有太大额的数字资产，可以不用考虑

一般推荐新手使用轻钱包，轻钱包操作简单易上手，个人使用过的极客钱包(geekwallet)

简单便捷的轻钱包，支持比特币（BTC）、莱特币（LTC）、以太坊（ETH）、EOS、USDT等主流数字货币资产的存储与管理。

采用BIP44助记词、本地私钥、离线签名等安全机制，以及手机、电脑双备份策略，彻底解决被黑客攻击、感染病毒、手机丢失、遗忘助记词等各种方式导致的数字货币资产丢失，为用户提供线上多链数字资产一站式管理服务。平台还有跳骚市场，可以进行实物资产上链的代币买卖。

❺ 想了解一下区块链钱包，有人可以介绍下吗

你好。
普通投资者和用户能使用钱包达成什么需求的操作。
想到钱包，你会想到什么？
1、热钱包、冷钱包、观察钱包。——实现一个钱包最基础的功能：存储。
2、不同公链的dApp入口。——持币者通往各个公链的dApp的入口。
3、闪兑、进入交易所直接交易、变现。——数字资产的交易、变现。
4、关注行情——看资讯，了解币价。
是的，这些功能，有些区块链钱包都已经实现了。会让人有种“小小的钱包，大大的世界”的感觉。用户想在区块链世界完成的动作，在钱包里基本都能解决了。
可以拿我常常使用的Tokenpocket钱包为例。
一、如何理解热钱包、冷钱包、观察钱包？
热钱包：就是在线钱包，联网钱包。方便提币，也可以随时查看钱包资产情况，余额、交易记录等。
冷钱包：就是离线钱包，既然是离线的不联网的钱包，那当我有转账、提币需求时如何实现呢？就用观察钱包。
观察钱包：观察冷钱包的资产情况，协助将冷钱包的资产完成提币操作的钱包。
二、TP SDK集成TRON
TokenPocket最新版TP SDK现已支持TRON,也就是说当波场公链上的独立dApp接入TokenPocket SDK后，可以实现TRON授权登陆、数据签名、Token转账、交易签名等操作。
这样的话，大大加速了TRON独立dApp的发展。
三、资产归集功能
我们通常存在这样的现象：每个人都拥有多个账号，而这些账号里又都有同一个token，想把这些不同账号上的同一资产归集到一起就需要资产归集这个功能。
这里存在一个问题：你各个账号的密码如果都一样，那么授权一次即可。如果密码都不同，那就需要每次都授权。
注意：在归集操作完成前，请不要关闭或者退出归集界面以防出错。
四、体验各个公链上丰富多彩的dapp
在TP界面，选择TRON分类，即可进入Tron Dapp页面。玩各种Dapp，或者进入其他公链，比如EOS，井通等。
钱包还有更多功能，等待进一步挖掘。

❻ 币圈内的一些专业术语是什么

1、Blockchain——区块链

区块链是分布式数据存储、点对点传输、共识机制、加密货币算法等计算机技术的新型应用模式。是一个共享的分布式账本，其中交易通过附加块永久记录。

2、Block——区块

在比特币网络中，数据会以文件的形式被永久记录，我们称这些文件为区块。一个区块是一些或所有最新比特币交易的记录集，且未被其他先前的区块记录。

3、Node——节点

由区块链网络的参与者操作的分类帐的副本。

4、去中心化

去中心化是一种现象或结构，必须在拥有众多节点的系统中或在拥有众多个体的群中才能出现或存在。节点与节点之间的影响，会通过网络而形成非线性因果关系。

5、共识机制

共识机制是通过特殊节点的投票，在很短的时间内完成对交易的验证和确认；对一笔交易，如果利益不相干的若干个节点能够达成共识，我们就可以认为全网对此也能够达成共识。

6、Pow——工作量证明

Proofof Work，是指获得多少货币，取决于你挖矿贡献的工作量，电脑性能越好，分给你的矿就会越多。

7、PoS——权益证明

Proofof Stake，根据你持有货币的量和时间进行利息分配的制度，在POS模式下，你的“挖矿”收益正比于你的币龄，而与电脑的计算性能无关。

8、智能合约

智能合约是一种旨在以信息化方式传播、验证或执行合约的计算机协议。智能合约允许在没有第三方的情况下进行可信交易，这些交易可追踪且不可逆转。

9、时间戳

时间戳是指字符串或编码信息用于辨识记录下来的时间日期。国际标准为ISO 8601。

10、图灵完备

图灵完成是指机器执行任何其他可编程计算机能够执行计算的能力。

11、Dapp——去中心化应用

是一种开源的应用程序，自动运行，将其数据存储在区块链上，以加密货币令牌的形式激励，并以显示有价值证明的协议进行操作。

12、DAO——去中心化自治组织

可以认为是在没有任何人为干预的情况下运行的公司，并将一切形式的控制交给一套不可破坏的业务规则。

13、PrivateKey——私钥

私钥是一串数据，它是允许你访问特定钱包中的令牌。它们作为加密货币，除了地址的所有者之外，都被隐藏。

14、PublicKey——公钥

是和私钥成对出现的，公钥可以算出币的地址，因此可以作为拥有这个币地址的凭证。

15、矿机

尝试创建区块并将其添加到区块链上的计算设备或者软件。在一个区块链网络中，当一个新的有效区块被创建时，系统一般会自动给予区块创建者（矿机）一定数量的代币，作为奖励。

16、矿池

是一个全自动的挖矿平台，使得矿机们能够贡献各自的算力一起挖矿以创建区块，获得区块奖励，并根据算力贡献比例分配利润（即矿机接入矿池—提供算力—获得收益）。

17、公有链

完全开放的区块链，是指任何人都可读取的、任何人都能发送交易且交易能获得有效确认的、全世界的人都可以参与系统维护工作，任何人都可以通过交易或挖矿读取和写入数据。

18、私有链

写入权限仅面向某个组织或者特定少数对象的区块链。读取权限可以对外开放，或者进行任意程度地限制。

19、联盟链

共识机制由指定若干机构共同控制的区块链。

20、侧链

楔入式侧链技术（pegged sidechains），它将实现比特币和其他数字资产在多个区块链间的转移，这就意味着用户们在使用他们已有资产的情况下，就可以访问新的加密货币系统。

21、跨链技术

跨链技术可以理解为连接各区块链的桥梁，其主要应用是实现各区块链之间的Atom交易、资产转换、区块链内部信息互通，或解决Oracle的问题等。

22、硬分叉

区块链发生永久性分歧，在新共识规则发布后，部分没有升级的节点无法验证已经升级的节点生产的区块，通常硬分叉就会发生。

23、软分叉

当新共识规则发布后，没有升级的节点会因为不知道新共识规则下，而生产不合法的区块，就会产生临时性分叉。

24、Hash——哈希值

一般翻译做”散列”，也有直接音译为”哈希”的。简单的说就是一种将任意长度的消息压缩到某一固定长度的消息摘要的函数。

25、主链

主链一词源于主网（，相对于测试网），即正式上线的、独立的区块链网络。

对币圈“行话”还不了解的小伙伴，赶快来学习一下：

1、法币是什么？

法币是法定货币，是由国家和政府发行的，只有政府信用来做担保，如人民币、美元等等。

2、token是什么？

token，通常翻译成通证。Token是区块链中的重要概念之一，它更广为人知的名字是“代币”，但在专业的“链圈”人看来，它更准确的翻译是“通证”，代表的是区块链上的一种权益证明，而非货币。

Token的三个要素

一是数字权益证明，通证必须是以数字形式存在的权益凭证，代表一种权利、一种固有和内在的价值；

二是加密货币，通证的真实性、防篡改性、保护隐私等能力由加密货币学予以保障；

三是能够在一个网络中流动，从而随时随地可以验证。

3、建仓是什么？

币圈建仓也叫开仓，是指交易者新买入或新卖出一定数量的数字货币。

4、梭哈是什么？

币圈梭哈就是指把本金全部投入。

5、空投是什么？

空投是目前一种十分流行的加密货币营销方式。为了让潜在投资者和热衷加密货币的人获得代币相关信息，代币团队会经常性地进行空投。

6、锁仓是什么？

锁仓一般是指投资者在买卖合约后，当市场出现与自己操作相反的走势时，开立与原先持仓相反的新仓，又称对锁、锁单，甚至美其名曰蝴蝶双飞。

7、糖果是什么？

币圈糖果即各种数字货币刚发行处在ICO时免费发放给用户的数字币，是虚拟币项目发行方对项目本身的一种造势和宣传。

8、破发是什么？

破指的是跌破，发指的是数字货币的发行价格。币圈破发是指某种数字货币跌破了发行的价格。

9、私募是什么？

币圈私募是一种投资加密货币项目的方式，也是加密货币项目创始人为平台运作募集资金的最好方式。

10、K线图怎么看？

K线图（Candlestick Charts）又称蜡烛图、日本线、阴阳线、棒线、红黑线等，常用说法是“K线”。它是以每个分析周期的开盘价、最高价、最低价和收盘价绘制而成。

11、对冲是什么？

一般对冲是同时进行两笔行情相关、方向相反、数量相当、盈亏相抵的交易。在期货合约市场，买入相同数量方向不同的头寸，当方向确定后，平仓掉反方向头寸，保留正方向获取盈利。

12、头寸是什么？

头寸是一种市场约定，承诺买卖合约的最初部位，买进合约者是多头，处于盼涨部位；卖出合约为空头，处于盼跌部位。

13、利好是什么？

利好：指币种获得主流媒体关注，或者某项技术应用有突破性进展，有利于刺激价格上涨的消息，都称为利好。

14、利空是什么？

利空：促使币价下跌的消息，如比特币技术问题，央行打压等。

15、反弹是什么？

币价在下跌趋势中因下跌过快而回升的价格调整现象。回升幅度小于下跌幅度。

16、杠杆是什么？

杠杆交易，顾名思义，就是利用小额的资金来进行数倍于原始金额的投资，以期望获取相对投资标的物波动的数倍收益率，抑或亏损。

❼ 关于币圈，有哪些是需要我们了解的

如果你刚刚入坑币圈，正欲入手数字货币，别着急，先静下心来看一看下面的内容，我猜一定会对你有所帮助。

一、什么是数字货币钱包
很多人说，数字货币钱包就是用来装数字货币的，通俗来讲这样理解没有问题，但实际上，数字货币钱包装的并不是数字货币，而是装密钥（私钥和公钥）的工具，有了密钥就可以拥有相应地址上的数字货币的支配权，利用钱包中生成的数字货币收款地址，可以接受他人给你转账的数字货币，也可以把你所拥有的数字货币转账给其他人。通俗来讲可以理解为用来存储和交易数字货币。

二、数字货币钱包的结构
1、地址：
钱包地址是一串字符串，作用是用来转账，钱包地址可以理解成银行卡卡号，可以告诉任何人，知道你钱包地址的任何人都可以给你的钱包地址转数字货币，不同的数字货币地址也是不同的，比如eos和btc的地址并不一样。
2、私钥
私钥是由系统根据用户环境中的随机因数，通过密码学算法生成的随机数。可以把它看成是银行卡密码，每次交易，付款方必须出具私钥，以及私钥产生的签名。
3、公钥
公钥是由私钥生成的，和私钥成对儿出现，公钥可以算出地址，主要用来生成地址。
4、密码
在创建钱包时，需要设置一个密码，密码的使用主要是：1.转账时的支付密码；2.导入钱包时需要验证密码。密码是用户主动设置的，但是安全性远低于私钥。密码主要起到双重保护的作用。
5、助记词
助记词是私钥的另一种表现形式，功能等同于私钥，助记词一般为12-15个或更多个英文单词组成，通过助记词就能找到私钥，还原钱包，因此助记词很重要，大多数钱包会提示用户备份助记词，以便恢复钱包。

三、数字货币钱包的分类
大体上可分为两大类，热钱包（在线钱包）和冷钱包（离线钱包）
（一）热钱包：
又称在线钱包，包含轻钱包和重钱包（全节点钱包），需保持连网上线的钱包，可以直接进行交易操作。
1、轻钱包：
不储存完整的区块链，只保存和自已相关的数据。它的体积小，可以在手机、电脑、网页等运行。
优缺点：不占用内存、支持多种数字资产、用户体验好、新手上手快，但交易验证稍慢

2、重钱包（全节点钱包）
维护着全部的区块链数据，完全去中心化，同步所有数据。具有更好的隐私性、可以在本地验证交易数据的有效性。
热钱包的优缺点：具有更好的隐私性、验证信息更快速，但每次使用都需要前需要同步数据，占用很大的硬盘空间，不支持多种数字货币交易。
（二）冷钱包：
冷钱包就是不连网的钱包，也叫离线钱包；比如专业的硬件设备，或者将私钥（助记词）写在纸上。
1、硬件钱包
硬件钱包即是用专业的硬件存储数字货币，将数字资产私钥单独储存在一个芯片中，与互联网隔离，即插即用。
2、纸钱包
把私钥写在纸上存储，再删除

冷钱包的优缺点：相对比较安全，但创建钱包和交易都非常麻烦，对于新手来说操作比较困难，钱包价格都相对昂贵，一般从几千到上万元不等。如果没有太大额的数字资产，可以不用考虑。

四、如何选择数字货币钱包
轻钱包使用起来更简单便捷，一般都支持多币种，一般适合新入币圈的小白或交易和存储量不大的用户使用。比如极客钱包（geekwallet）
硬件钱包不联网，安全性更高，但操作相对复杂，一般适合交易和存储量比较大的用户。

五、使用数字货币钱包时的注意事项

1、保管好密码，一旦丢失，不能找回。不过可以通过助记词重置密码（前提是安全保管好助记词）。
2、保管好私钥，私钥拥有者才是比特币真正的拥有者。
3、保管好助记词，一但别人拿到这个助记词，别人就能把助记词对应钱包内的区块链资产全部转走。

❽ 什么是区块链数字资产冷钱包、热钱

比特币钱包有很多种形态，如PC或手机钱包客户端、在线网页钱包、甚至是记录了比特币私钥的小本本（纸钱包）或者大脑（脑钱包）。你可以根据需求来选择适合自己的钱包。

比特币钱包按照私钥的存储方式，可以分为冷钱包、热钱包两种。

01、冷钱包是指网络不能访问到你私钥的钱包。

冷钱包往往依靠“冷”设备确保比特币私钥的安全，比如不联网的电脑、手机、写着私钥地址的小本本等。冷钱包避免了被黑客盗取私钥的风险，但是可能面临物理安全风险，比如电脑丢失损坏等。

02、热钱包是指互联网能购访问你私钥的钱包。

热钱包往往是在线钱包的形式。使用热钱包时，最好在不同平台设置不同密码，且开启二次认证，以确保自己的资产安全。

钱包其实就是“私钥、地址和区块链数据的管理工具”。

❾ 什么是比特币热钱包

是指在线的钱包，使用比特币热钱包的用户一般不直接持有比特币钱包私钥，即使持有私钥也是储存在网络上的私钥。因此它就存在被黑客攻破和盗窃的风险。但相应的，因为比特币热钱包始终连接着网络，所以它就能够以更为快捷的速度为用户提供比特币存取服务。

❿ 冷钱包、热钱包分别是什么东西啊

冷钱包就是等于把你的私钥和网络隔绝了，现在冷钱包也可以放卡里面，更安全，我用的就是酷宝冷钱包

❶ What are hot wallets and cold wallets

Hot wallets refer to wallets that are connected to the Internet in any way. For example, when you create an account on Binance and send funds to your personal wallet, you use Binance’s hot wallet. These wallets are fairly simple to set up and funds can be accessed quickly, making them easy for traders and other high-frequency users to use.

❷ What is the difference between Bitcoin cold wallet and hot wallet? What about the currency wallet?

Bitcoin cold wallet refers to a Bitcoin storage method in which user accounts and personal keys are stored separately. .
Hot wallets usually refer to Bitcoin online wallets. Users’ personal account and password information are all stored on a network platform; the website platform provides users with security.
Bibao is a website platform that specializes in providing Bitcoin wallet services. It has two storage methods: cold wallet and hot wallet; overall, user reviews are good.

❸ What is a cold wallet?

In general, a cold wallet is a wallet that stores digital currency offline. Players generate digital currency addresses and private keys on an offline wallet. , and then save it. Cold wallets store digital currency without any network, so hackers cannot enter the wallet to obtain the private key.

❹ Classification of digital currency wallets

In general, blockchain wallets are used to store digital currencies. In fact, blockchain wallets do not store digital currencies, but It is a tool for storing keys (private keys and public keys). With the key, you can have control over the digital currency at the corresponding address. Using the digital currency payment address generated in the blockchain wallet, you can accept others to give you You can also transfer the digital currency you own to others

Classification of digital currency wallets:

It can be roughly divided into two categories, hot wallets ( Online wallet) and cold wallet (offline wallet)

1. Hot wallet

Hot wallet is also called online wallet, including light wallet and heavy wallet (full node wallet), which need to be connected Online wallets can directly perform transaction operations.

1. Light wallet:

Does not store the complete blockchain, but only saves data related to itself. It is small in size and can be run on mobile phones, computers, web pages, etc.

Advantages and disadvantages: Does not occupy memory, supports a variety of digital assets, good user experience, quick to get started with novices, but transaction verification is slightly slow

2. Heavy wallet (full Node wallet)

Maintains all blockchain data, is completely decentralized, and synchronizes all data. It has better privacy and can verify the validity of transaction data locally.

Advantages and disadvantages: It has better privacy and faster verification of information, but it requires data synchronization before each use, takes up a lot of hard drive space, and does not support multiple digital currency transactions.

2. Cold wallet

A cold wallet is a wallet that is not connected to the Internet, also called an offline wallet;For example, professional hardware equipment, or writing the private key (mnemonic phrase) on paper.

1. Hardware wallet

Hardware wallet uses professional hardware to store digital currency, and stores the private key of digital assets separately in a chip, which is isolated from the Internet and is plug-and-play. .

2. Paper wallet

Write the private key on paper and store it, then delete it

Advantages and disadvantages of cold wallet:

It is relatively safe, but it is very troublesome to create a wallet and make transactions. It is difficult for novices to operate. Wallet prices are relatively expensive, generally ranging from a few thousand to tens of thousands of yuan. If you don’t have a large amount of digital assets, you don’t need to consider it.

It is generally recommended for novices to use light wallets. Light wallets are simple and easy to use. I have personally used geekwallet

A simple and convenient light wallet that supports the storage and management of mainstream digital currency assets such as Bitcoin (BTC), Litecoin (LTC), Ethereum (ETH), EOS, and USDT.

Using BIP44 mnemonic phrases, local private keys, offline signatures and other security mechanisms, as well as dual backup strategies for mobile phones and computers, to completely solve various problems such as being attacked by hackers, infected with viruses, losing mobile phones, forgetting mnemonic phrases, etc. To prevent the loss of digital currency assets caused by various methods, we provide users with one-stop management services for online multi-chain digital assets. The platform also has a flea market, which allows for the purchase and sale of tokens with physical assets on the chain.

❺ I would like to know about blockchain wallet, can someone introduce it?

Hello.
What operations can ordinary investors and users use the wallet to achieve.
When you think of a wallet, what comes to mind?
1. Hot wallet, cold wallet, observation wallet. ——Realize the most basic function of a wallet: storage.
2. dApp entrances to different public chains. ——The entrance for currency holders to dApps on various public chains.
3. Flash swap, enter the exchange for direct trading and cash out. ——Transaction and realization of digital assets.
4. Pay attention to the market - read the information and understand the currency price.
Yes, some blockchain wallets have already implemented these functions. It will give people a feeling of "small wallet, big world". The actions that users want to complete in the blockchain world can basically be solved in the wallet.
You can take the Tokenpocket wallet that I often use as an example.
1. How to understand hot wallet, cold wallet and observation wallet?
Hot wallet: It is an online wallet, an online wallet. It is convenient to withdraw coins, and you can also check the wallet assets, balance, transaction records, etc. at any time.
Cold wallet: It is an offline wallet. Since it is an offline wallet that is not connected to the Internet, how can I achieve it when I need to transfer or withdraw money? Just watch your wallet.
Observation wallet: A wallet that observes the assets in the cold wallet and assists in withdrawing the assets from the cold wallet.
2. TP SDK integrates TRON
The latest version of TokenPocket TP SDK now supports TRON, which means that when an independent dApp on the Tron public chain is connected to the TokenPocket SDK, it can realize TRON authorized login, data signature, Token transfer, transaction signature, etc. operate.
In this case, the development of TRON’s independent dApp will be greatly accelerated.
3. Asset aggregation function
We usually have this phenomenon: everyone has multiple accounts, and these accounts all have the same token, and they want to pool the same assets on these different accounts To bring them together, the function of asset aggregation is needed.
There is a problem here: if the passwords for each of your accounts are the same, you only need to authorize them once. If the passwords are different, you need to authorize each time.
Note: Please do not close or exit the collection interface before the collection operation is completed to prevent errors.
4. Experience the colorful dapps on each public chain
In the TP interface, select the TRON category to enter the Tron Dapp page. Play various Dapps, or enter other public chains, such as EOS, Jingtong, etc.
The wallet has more functions, waiting for further exploration.

❻ What are some professional terms in the currency circle

1. Blockchain——Blockchain

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. is a shared distributed ledger where transactions are permanently recorded through appended blocks.

2. Block——Block

In the Bitcoin network, data will be permanently recorded in the form of files. We call these files blocks. A block is a set of records of some or all of the latest Bitcoin transactions that have not been recorded by other previous blocks.

3. Node - A copy of the ledger operated by participants in the blockchain network.

4. Decentralization

Decentralization is a phenomenon or structure that must appear or exist in a system with many nodes or in a group with many individuals. The influence between nodes will form a non-linear causal relationship through the network.

5. Consensus mechanism

The consensus mechanism is to complete the verification and confirmation of transactions in a very short time through the voting of special nodes; for a transaction, if the interests are irrelevant If several nodes can reach a consensus, we can think that the entire network can also reach a consensus on this.

6. Pow - Proof of Work

Proof of Work refers to how much currency you get, depending on the workload you contribute to mining. The better the computer performance, the more money will be allocated to you. There will be more mines.

7. PoS——Proof of Stake

Proof of Stake is a system for allocating interest based on the amount and time you hold the currency. In POS mode, your "mining" income is proportional to your currency age, and is proportional to the computer has nothing to do with computing performance.

8. Smart Contract

Smart contract is a computer protocol designed to spread, verify or execute contracts in an information-based manner. Smart contracts allow trusted transactions to be made without third parties, which are traceable and irreversible.

9. Timestamp

Timestamp refers to a string or encoded information used to identify the recorded time and date. The international standard is ISO 8601.

10. Turing completeness

Turing completeness refers to the ability of a machine to perform any calculation that any other programmable computer can perform.

11. Dapp - decentralized application

It is an open source application that runs automatically and stores its data on the blockchain in the form of cryptocurrency tokens. Form incentives and operate with a protocol that displays proof of value.

12. DAO - Decentralized Autonomous Organization

It can be thought of as a company that operates without any human intervention and hands all forms of control to a set of uncontrollable entities. Broken business rules.

13. PrivateKey - Private Key

A private key is a string of data that allows you to access a token in a specific wallet. They, as cryptocurrencies, are hidden except from the owner of the address.

14. PublicKey——Public key

It appears in pairs with the private key. The public key can calculate the address of the currency, so it can be used as a certificate for owning the address of the currency.

15. Mining machine

A computing device or software that attempts to create blocks and add them to the blockchain. In a blockchain network, when a new valid block is created, the system will generally automatically give the block creator (mining machine) a certain number of tokens as a reward.

16. Mining pool

It is a fully automatic mining platform that allows miners to contribute their own computing power to mine together to create blocks and obtain block rewards. And the profits are distributed according to the proportion of computing power contribution (that is, the mining machine is connected to the mining pool - provides computing power - obtains income).

17. Public chain

A completely open blockchain refers to a fully open blockchain that can be read by anyone, anyone can send transactions, and transactions can be effectively confirmed. People around the world can participate in system maintenance, and anyone can read and write data through transactions or mining.

18. Private chain

A blockchain where write permission is only for a certain organization or a specific few objects. Read permissions can be open to the outside world, or restricted to any degree.

19. Alliance chain

The consensus mechanism is a blockchain jointly controlled by a number of designated institutions.

20. Sidechains

Pegged sidechains technology will enable the transfer of Bitcoin and other digital assets between multiple blockchains, which means that users Using their existing assets, they can access the new cryptocurrency system.

21. Cross-chain technology

Cross-chain technology can be understood as a bridge connecting various blockchains. Its main application is to realize Atom transactions, asset conversion, and partitioning between blockchains. Information exchange within the blockchain, or solving Oracle problems, etc.

22. Hard fork

The blockchain has a permanent divergence. After the new consensus rules are released, some nodes that have not been upgraded cannot verify the blocks produced by the upgraded nodes. Usually a hard fork happens.

23. Soft fork

When the new consensus rules are released, nodes that have not been upgraded will produce illegal blocks because they do not know the new consensus rules, which will cause Temporary forks.

24. Hash——Hash value

Generally translated as "hash", there are also direct transliterations as "hash". Simply put, it is a function that compresses a message of any length into a message digest of a fixed length.

25. Main chain

The term main chain comes from the main network (relative to the test network), which is an independent blockchain network that is officially online.

For those who don’t understand the “jargon” of the currency circle, come and learn it quickly:

1. What is legal currency?

Legal currency is legal tender, issued by the country and the government, and is only guaranteed by government credit, such as RMB, US dollars, etc.

2. What is token?

Token, usually translated as pass. Token is one of the important concepts in the blockchain. It is more commonly known as "token", but in the eyes of professional "chain circle" people, its more accurate translation is "pass", which represents the area. A proof of stake on the blockchain, not a currency.

The three elements of Token

The first is digital proof of rights and interests. The token must be a certificate of rights and interests in digital form, representing a right and an inherent and intrinsic value;

The second is cryptocurrency. The authenticity, tamper resistance, privacy protection and other capabilities of the token are guaranteed by cryptography;

The third is the ability to flow in a network, so that It can be verified anytime and anywhere.

3. What is position building?

Building a position in the currency circle is also called opening a position, which refers to a trader’s new purchase or sale of a certain amount of digital currency.

4. What is stud?

Cryptocurrency stud means investing all the principal.

5. What is an airdrop?

Airdrops are currently a very popular cryptocurrency marketing method. In order to provide potential investors and people who are passionate about cryptocurrency with information related to the token, the token team will regularlyairdrop.

6. What is lock-up?
