Ⅰ 虚拟币bid和ask是什么意思

bid是买单价格，ask是卖单价格，bid等于ask就是成交价格。
这是交易平台的专业术语，很容易理解。
现在的虚拟货币圈是乱草丛生，投资者需要擦亮自己的眼睛，尤其是对那些新生的虚拟货币，更要慎重，新生的币多为传销币。老牌的虚拟货币有比特币、瑞泰币、莱特币、以太坊等等。

Ⅱ 币圈内的一些专业术语是什么

26个区块链行业常用名词解释

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。

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

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？

Ⅲ 比特币是什么通俗解释

比特币的术语是“一种P2P形式的虚拟的加密数字货币，点对点的传输意味着一个去中心化的支付系统。”如果你不理解区块链技术也就无法理解比特币，如果对区块链不了解的朋友，可以看看我之前写的文章，区块链是什么？怎么通俗解释它？看完这三点你就明白了！下面通过一个小故事了解比特币。
假如有这样一个环境位，单位每个人都有一个公共账本，这个账本详细记录单位每一笔资金的明细，如果小王报销了200块钱的费用，每个人手里的账本都会自动出现小王因公外出单位支出200元的记录，这种情况下不可能出现假账了，因为信息都是透明的，不可能从中做手脚了。但是有一天每个人的手中的账本变成了一个软件，软件拥有不仅拥有记账功能，而且这个软件也可以用于转账支付，在这种环境下支付的虚拟货币称为比特币。这是对比特币最简单的解释，为了便于大家理解，某些地方说的不严谨，真正的比特币技术要复杂得多。

拓展资料：

比特币特点
1、不可重复性
例如你只有1比特币，你支付了别人1比特币，如果你在试图支付其他人1比特币就会失败，因为你支付完同时周围的节点会检查你实际上没有比特币了，并拒绝你这笔非法支付。这种不可复制性具有货币的属性，但可以很好解决现实生活中出现假币的问题，比特币不同于现实中的货币都是围绕银行进行的，而比特币是点对点交易的没有中心。
2、安全性
上面通过记账本比喻生动说明了比特币别于传统的货币最大特点，比特币不受任何人或任何组织的控制，数据在多台设备上完整又独立，安全性更有保证。
3、独特性
比特币独特性在于它是虚拟的货币，虽然现在只有很少一部分工作承认比特币是货币可用于支付，虽然它现在会不是真正的货币，但是毋庸置疑比特币是首次出现数字货币，这是这一点大大改变了世界。

Ⅳ 比特币专业术语中的“硬分叉”是什么意思

硬叉指的是对区块链网络协议的根本改变有效地导致两个分支，一个遵循先前的协议另一个遵循新版本

Ⅳ 币圈薄饼什么意思

币圈薄饼指的是PancakeSwap。去中心化交易所，从技术角度来看，去中心化交易所是通过链上的智能合约来实现交易的；从治理角度来看，去中心化交易所的治理带有开放和社区驱动的属性。
拓展资料
关于比特币
一、币圈指关注或者投资虚拟加密数字货币的人形成的圈子，大饼指的是比特币。比特币的概念最初由中本聪在 2009 年提出，是一种点对点，去中心化的数字资产。共2100万枚，预计2140年发行完毕，具有极强的稀缺性，不过国内不能进行比特币交易。 比特币支持全世界7*24小时交易，可以在任意一台接入互联网的电脑上买卖，不管身处何方，任何人都可以挖掘、购买、出售或收取比特币，并且在交易过程中外人无法辨认用户身份信息。
二、比特币具有的特点包括去中心化、无隐藏成本、专属所有权、跨平台挖掘等。由于比特币完全依赖P2P网络，无发行中心，所以外部无法关闭它，值得一提的是，比特币兑换现金的价格如过山车一般起伏，很多人投资时出现亏损。 比特币进行交易时和电子邮件的电子现金有很多的相似之处，交易比特币时双方需要“比特币钱包”和“比特币地址”。汇款方通过电脑或智能手机，按收款方地址将比特币直接付给对方。
三、比特币是股市中第一家上市的公司，中本聪属于该公司的创始人。中本聪家开发了比特币系统，中本聪作为其创始人，他自然能够获得更多的股份。比特币的总数将不会超过2100万，让我们假设比特币公司拥有2100万股。在中国投资圈里，有一个术语叫做““画大饼“”，也就是说，想要获得融资的人，将描述他们所做事情的巨大前景，让投资者相信他们的项目的潜力，然后从投资者那里得到真正的黄金白银。此过程称之为推出。 以此推算，融资者和投资者相继向其他投资者宣传其项目，方便继续退出。目前本世纪最大的饼属于比特币。

Ⅵ 币圈ifo是什么意思

所谓IFO（Initial Fork Offerings 首次分叉币发行），指的是基于比特币、以太坊等主流币种而进行的分叉，在这些主流币的原有区块链基础上，按照不同规则分裂出另一条链。由于持有比特币、以太坊等主流币种的人可以在IFO过程中获得分叉后的新币，因此IFO也被业内认为是一种新的虚拟货币融资手段。

在“币圈”，第一次IFO被认为是比特币分叉产生BCH（比特币现金）的过程。由于比特币是通过各个网络节点计算数据而产生的，而比特币区块大小只有1MB（相当于网络带宽），造成比特币交易拥堵而缓慢。2017年8月初，比特币被人以技术手段分叉，产生一种新的数字货币BCH，后者的区块大小为8MB，而且区块容量可调整，但在数量和算法方面仍和比特币保持一样，拥有比特币的人可按1：1的比例免费获得BCH。

由于比特币是开源的技术项目，且IFO不需要经过比特币开发团队的同意，所以只需在比特币的基础上分叉，并给拥有旧币种的人1：1发放新币种（这一过程也被业内称为“分糖果”）。这一过程，也被业内视为继ICO之后，另一种新的变相发行虚拟货币的方式。

BCH分叉成功后，越来越多新的虚拟货币通过IFO的方式产生了：BTG（比特币黄金）、BCD（比特币钻石）、SBTC（超级比特币）、LBTC（闪电比特币）、BTP（比特币白金）、BCK（比特币王者）、BTG（比特币上帝）

由于越来越多新的币种出现，币圈人士经常感慨“币圈一日，人间一年”。加密货币交易所排行网站CoinMarketCap显示，全球现有8100多个虚拟货币交易所，流通的虚拟货币近1500种。随着IFO等手段的逐渐普及，还将出现各种新的虚拟货币。

BCH等IFO项目的成功示范，以及ICO在国内被“一刀切”禁止的现实，让许多“币圈”新人也开始摩拳擦掌参与IFO。这类需求在无形中也催生了代写IFO商业计划书的服务。

在淘宝网上，有不少声称可以制作ICO 区块链白皮书的商家。一位淘宝店家的客服告诉中国青年报·中青在线记者，只要提供IFO项目的具体思路、团队介绍、“糖果”分配方案等资料，就可以代写完整的IFO项目白皮书，包括专业技术术语和图表，相应的服务费则需要数千元。“越要求真实，就越要提供更多的资料。”

Ⅶ 关于区块链行业的相关术语有哪些

1、实用令牌

6、公链

公共链是具有高度“公共性”的区块链，任何人都可以自由地参与网络。

术语用法示例

作为调解区块链之间数据交换的基础设施项目，将建立一种在公共区块链上交换数据的机制。

详细说明

在用于记录加密资产（虚拟货币）交易信息的区块链中，这是一种机制，用于由未指定数量的参与者在没有特定管理实体的情况下共识建立交易信息。防止伪造交易信息是非常安全的，但是它需要大量的计算，因此它的缺点是，在有很多参与者的情况下，完成交易需要花费很长时间。

7、可伸缩性问题

可伸缩性问题是指延迟事务处理的“可扩展性”问题。

术语用法示例

飙升的汽油价格突出了以太坊的可扩展性问题。

详细说明

由于区块链的性质，由于可在一个块中写入的交易数据量有限，因此处理延迟。汇款可能需要很长时间，这会导致更高的交易费用。比特币是诞生的第一个加密货币，已经被认为是一个特殊的问题，但是解决该问题的努力已得到实施，例如利用闪电网络等其他技术并开发新的区块链。

8、GAS费用

GAS费用是以太坊区块链上的（网络）交易费用。

术语用法示例

本周，在以太坊区块链上，尽管有少量汇款，但仍有多起高额天然气账单被支付的案例。

详细说明

用户指定金额的GAS费用是次要奖励。虚拟货币以太坊（ETH）用于付款。由于首先要处理费用较高的交易，因此GAS费用可能会随着交易数量的增加而增加。

9、流动性采矿（流动性采矿）

考虑到提供流动性（货币对），流动性挖掘是指除利息外还授予治理令牌，以吸引那些执行收益率制衡的人。

术语用法示例

流动性开采正在加速收益丰厚。

详细说明

在流动性挖掘中，通过将特定资产存储在流动性池中并提供交易者可以买卖的流动性，可以将当时的掉期费作为收入获得。这些流动性挖掘源于最大的去中心化交易所“ Uniswap”，并且诞生了许多流动性挖掘合同，例如Curve Finance和Balancer。

10、DeFi（分布式金融）

DeFi（去中心化金融）是指利用区块链并且在没有中央管理员的情况下提供的金融服务或系统。

术语用法示例

自2020年6月以来，DeFi市场发展迅猛。

详细说明

“分散式金融”的缩写。DeFi提供的金融服务包括发行稳定的硬币，借出货币和加密货币交易所。许多平台使用以太坊区块链。

11、PoS（权益证明）

PoS是一种共识算法，可让您根据自己拥有的虚拟货币的百分比（权益）批准和生成新区块的权利。

术语用法示例

以太坊联合创始人Vitalik Buterin表示，将ETH的共识算法从PoW迁移到PoS将改善安全性和扩展性。

详细说明

权益证明的缩写。还可以考虑虚拟货币的持有期。它诞生于“工作量证明（PoW）”共识算法的替代方案，该算法需要高性能的计算机来批准交易并消耗大量能量。如果批准，您可以收到新发行的虚拟货币作为奖励。

12、dApps

dApp是使用开源区块链开发的应用。

术语用法示例

韩国最大的三星电子应用商店“ Galaxy Store”已开始使用Tron的区块链处理dApp。

详细说明

“分散的应用程序”的缩写，在日语中称为“分散的应用程序”。一个主要功能是没有集中式管理员。最受欢迎的是以太坊区块链，正在开发诸如游戏和去中心化交易所（DEX）之类的应用程序。

Ⅷ 与加密货币（虚拟货币）采矿有关的相关术语有哪些

1、闪电网络

闪电网络是一种脱链技术，使用第2层消除了比特币的交易处理能力。

术语用法示例

加密货币交易所Bitfinex计划实施基于Tether的闪电网络（USDT）。

详细说明

如果引入了闪电网络（Lightning Network），则有可能在拥挤的区块链之外进行交易，从而加快交易速度并降低费用。如果可以加快交易速度并降低费用，则可以进行小额付款，这有望创造出新的产品和服务。

6、矿池

挖矿池是一个有组织的服务器，其创建目的是收集每个矿工的哈希值并在挖矿中进行协作。

术语用法示例

虚拟货币交易所Binance在采矿池中赚取的奖励可以由Binance直接进行交易。

详细说明

在规模至关重要的采矿业务中，多个矿工共同合作进行采矿的一种机制。奖励根据采矿的贡献支付。

7、半衰期

半衰期是指比特币等虚拟货币的采矿奖励（=新发行量）减少一半的时间。

术语用法示例

加密货币比特币（BTC）于2020年5月12日达到其第三个半衰期，采矿奖励从12.5 BTC降至6.25 BTC。

详细说明

许多虚拟货币具有防止通货膨胀的“发行限额”，并且每隔一定间隔的半衰期，新发行的发行量将减少一半。这也是虚拟货币特有的值得注意的事件，因为随着供应量的减少和价格趋于上涨，稀缺价值显着上升。

Ⅸ 比特币是什么 比特币的由来

1、比特币：

又称“比特金”，是一种网络虚拟货币，网民可以使用比特币购买一些虚拟物品，比如网络游戏当中的衣服、帽子、装备等，网民之间也有用来购买现实物品的情况。

2、比特币的由来:

比特币（BitCoin）的概念最初由中本聪在2009年提出，根据中本聪的思路设计发布的开源软件以及建构其上的P2P网络。比特币是一种P2P形式的数字货币。点对点的传输意味着一个去中心化的支付系统。

与大多数货币不同，比特币不依靠特定货币机构发行，它依据特定算法，通过大量的计算产生，比特币经济使用整个P2P网络中众多节点构成的分布式数据库来确认并记录所有的交易行为，并使用密码学的设计来确保货币流通各个环节安全性。

(9)比特币圈术语扩展阅读:

比特币的产生原理:

从比特币的本质说起，比特币的本质其实就是一堆复杂算法所生成的特解。特解是指方程组所能得到无限个（其实比特币是有限个）解中的一组。而每一个特解都能解开方程并且是唯一的。

以人民币来比喻的话，比特币就是人民币的序列号，知道了某张钞票上的序列号，就拥有了这张钞票。而挖矿的过程就是通过庞大的计算量不断的去寻求这个方程组的特解，这个方程组被设计成了只有 2100 万个特解，所以比特币的上限就是 2100 万。

Ⅹ 比特币相关的基础术语有哪些

比特币客户端（钱包）：是处理发送和接收比特币的软件。最流行的是从bitcoin官网下载的客户端。还有其他一些选择。
钱包：有两层含义，1、是指比特币客户端（客户端一般指桌面客户端；钱包一般指轻量级的客户端或在线钱包）；2、是指存储比特币地址和私钥的文件。
比特币地址：是一个诸如 “”的字符串，你可以从接收方获得。用客户端创建一个地址同时生成对应的私匙。
私匙：在比特币的背景下，私匙 是和对应地址相关联的（从技术上讲，地址是私钥 所对应的公钥 的哈希值），并且存储在底层，并允许您转移当前地址所拥有的比特币。请注意，因为Bitcoin的使用的ECDSA 加密算法，它能够生成从私钥生成对应的公钥和地址。
交易：交易是指一个通知整个比特币网络的信息，告诉全网交易的发生，允许接收者使用这些钱，防止发送者双重支付。

Ⅰ What do virtual currency bid and ask mean?

Bid is the buy order price, ask is the sell order price, and bid equal to ask is the transaction price.
This is a professional term for a trading platform and is easy to understand.
The current virtual currency circle is overgrown. Investors need to keep their eyes peeled, especially for new virtual currencies. Most of the new coins are pyramid schemes. The old virtual currencies include Bitcoin, Ritecoin, Litecoin, Ethereum, etc.

II What are some professional terms in the currency circle

Explanation of 26 common terms in the blockchain industry

1. Blockchain——Blockchain

p>

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

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 completion refers to the machine executionThe ability to perform calculations 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. This This means that users can access the new cryptocurrency system while using their existing assets.

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. PassHard forks often occur.

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 about the token, the token team will conduct frequent airdrops.

6. What is lock-up?

Lock position generally means that after investors buy and sell contracts, when the market trend is opposite to their own operations, they open a new position opposite to their original position. Its name is Butterfly Flying Double.

7. What is candy?

Cryptocurrency candies are digital coins that are distributed to users for free when various digital currencies are first issued and ICO. They are a kind of momentum and promotion for the project itself by the issuer of the virtual currency project.

Generally, hedging is to conduct two transactions at the same time that are related to the market, opposite in direction, of equal quantity, and with profits and losses offsetting. In the futures contract market, buy positions of the same quantity but in different directions. When the direction is determined, close the position in the opposite direction and retain the positive direction to gain profits.

12. What is a position?

Position is a market agreement that commits to buying and selling the initial position of a contract. Those who buy the contract are long and are in a position to expect an increase; those who sell the contract are short and are in a position to expect a decrease.

Ⅲ Popular explanation of what Bitcoin is

The term Bitcoin is “a virtual encrypted digital currency in the form of P2P. Point-to-point transmission means a decentralized payment system. ." If you don't understand blockchain technology, you won't be able to understand Bitcoin. If you don't understand blockchain, you can read the article I wrote before. What is blockchain? How to explain it in simple terms? You will understand after reading these three points! Let’s learn about Bitcoin through a short story.
If there is such an environment, everyone in the unit has a public ledger, which records the details of every fund in the unit. If Xiao Wang reimburses an expense of 200 yuan, the ledger in everyone's hand will automatically There is a record of Xiao Wang spending 200 yuan when he went out to work for work. In this case, there is no possibility of false accounts, because the information is transparent and there is no way to manipulate it. But one day the ledger in everyone's hands turned into a software. The software not only has accounting functions, but this software can also be used for transfer payments. The virtual currency paid in this environment is called Bitcoin. This is the simplest explanation of Bitcoin. In order to facilitate everyone's understanding, some places are not rigorous. The real Bitcoin technology is much more complicated.

Characteristics of Bitcoin
1. Non-repeatability
For example, if you only have 1 Bitcoin and you pay someone else 1 Bitcoin, if you are trying to pay someone else 1 Bitcoin will fail because after you pay, the surrounding nodes will check that you actually have no Bitcoin and reject your illegal payment. This non-replicability has the properties of currency, but it can well solve the problem of counterfeit currency in real life. Bitcoin is different from real currencies, which all revolve around banks, and Bitcoin has no center for peer-to-peer transactions.
2. Security
The above vividly illustrates the biggest feature of Bitcoin that is different from traditional currencies through the metaphor of a ledger. Bitcoin is not controlled by anyone or any organization, and the data is complete and independent on multiple devices. , security is more guaranteed.
3. Uniqueness
The uniqueness of Bitcoin is that it is a virtual currency. Although only a few works now admit that Bitcoin is a currency that can be used for payment. Although it is not a real currency now, there is no doubt that Bitcoin Coin was the first digital currency to appear, and it was this that changed the world significantly.

IV What is the meaning of "hard fork" in Bitcoin terminology

A hard fork refers to a fundamental change to the blockchain network protocol that is effective It leads to two branches, one following the previous protocol and the other following the new version

IV What does the currency circle pancake mean?

The currency circle pancake refers to PancakeSwap. From a technical perspective, decentralized exchanges implement transactions through smart contracts on the chain; from a governance perspective, the governance of decentralized exchanges is open and community-driven. .

About Bitcoin
1. The currency circle refers to the circle formed by people who pay attention to or invest in virtual encrypted digital currencies. The big pie refers to Bitcoin. The concept of Bitcoin was originally proposed by Satoshi Nakamoto in 2009. It is a peer-to-peer, decentralized digital asset. A total of 21 million coins are expected to be issued in 2140. They are extremely scarce, but Bitcoin transactions cannot be conducted domestically. Bitcoin supports 7*24-hour transactions around the world and can be bought and sold on any computer connected to the Internet. No matter where you are, anyone can mine, buy, sell or collect Bitcoin, and outsiders cannot during the transaction process. Identify user identity information.
2. The characteristics of Bitcoin include decentralization, no hidden costs, exclusive ownership, cross-platform mining, etc. Since Bitcoin completely relies on the P2P network and has no issuance center, it cannot be closed externally. It is worth mentioning that the price of converting Bitcoin to cash fluctuates like a roller coaster, and many people suffer losses when investing. There are many similarities between Bitcoin transactions and e-mail electronic cash. When trading Bitcoins, both parties need a "Bitcoin wallet" and a "Bitcoin address." The remitter pays Bitcoin directly to the other party according to the recipient's address through a computer or smartphone.
Three, Bitcoin is the first company listed on the stock market, and Satoshi Nakamoto is the founder of the company. Satoshi Nakamoto’s family developed the Bitcoin system. As its founder, Satoshi Nakamoto will naturally be able to obtain more shares. The total number of Bitcoins will not exceed 21 million, let us assume that the Bitcoin company owns 21 million shares. In Chinese investment circles, there is a term called "drawing a big pie", which means that people who want to obtain financing will describe the great prospects of what they are doing to convince investors of the potential of their projects, and then Get real gold and silver from investors. This process is called rollout. Extrapolating from this, financiers and investors successively promote their projects to other investors to facilitate further exits. The biggest pie of this century currently belongs to Bitcoin.

VI What does ifo mean in the currency circle?

The so-called IFO (Initial Fork Offerings) refers to the issuance of currencies based on mainstream currencies such as Bitcoin and Ethereum. Forks are based on the original blockchains of these mainstream currencies and split into another chain according to different rules. Because people who hold mainstream currencies such as Bitcoin and Ethereum can obtain new coins after the fork during the IFO process, IFO is also considered by the industry to be a new virtual currency financing method.

In the "currency circle", the first IFO is considered to be the process of Bitcoin forking to produce BCH (Bitcoin Cash). Since Bitcoin is generated by calculating data through various network nodes, and the Bitcoin block size is only 1MB (equivalent to network bandwidth), Bitcoin transactions are congested and slow. In early August 2017, Bitcoin was forked by technical means, resulting in a new digital currency BCH. The latter has a block size of 8MB and the block capacity is adjustable, but it is still the same as Bitcoin in terms of quantity and algorithm. Staying the same, people who own Bitcoin can get BCH for free at a 1:1 ratio.

Since Bitcoin is an open source technology project, and IFO does not need to be approved by the Bitcoin development team, it only needs to be forked on the basis of Bitcoin and give 1:1 to those who own the old currency. Issue new currencies (this process is also known in the industry as "candy distribution"). This process is also regarded by the industry as another new way to issue virtual currencies in disguised form after ICO.

After the successful BCH fork, more and more new virtual currencies have been produced through IFO: BTG (Bitcoin Gold), BCD (Bitcoin Diamond), SBTC (Super Bitcoin), LBTC ( Lightning Bitcoin), BTP (Bitcoin Platinum), BCK (Bitcoin King), BTG (Bitcoin God)

Due to the emergence of more and more new currencies, people in the currency circle often lament that “the currency circle One day, one year on earth.” According to CoinMarketCap, a cryptocurrency exchange ranking website, there are more than 8,100 virtual currency exchanges in the world, with nearly 1,500 virtual currencies in circulation. With the gradual popularization of IFO and other means, various new virtual currencies will also appear.

The successful demonstrations of IFO projects such as BCH, as well as the fact that ICOs are “one-size-fits-all” banned in China, have caused many newcomers in the “currency circle” to start gearing up to participate in IFOs. This kind of demand has also invisibly given rise to the service of ghostwriting IFO business plans.

On Taobao, there are many merchants who claim to be able to produce ICO blockchain white papers. A Taobao store customer service told China Youth Daily·China Youth Online reporter that as long as the specific ideas of the IFO project, team introduction, "candy" distribution plan and other information are provided, a complete IFO project white paper can be written, including professional technical terms and Charts and corresponding service fees cost thousands of dollars. "The more authenticity is required, the more information must be provided."

Ⅶ What are the relevant terms about the blockchain industry

1. Utility token

Utility token is A utility token that acts as a right to use a specific service.

Examples of term usage

Utility tokens are predicated on using a service.

Details

You can settle the price of goods and meals instead of cash, or you can access it by having cloud storage. For utility tokens, classification of audit reports is not required.

6. Public chain

A public chain is a highly "public" blockchain where anyone can freely participate in the network.

Examples of term usage

As an infrastructure project that mediates the exchange of data between blockchains, a mechanism for exchanging data on a public blockchain will be established.

Details

In a blockchain used to record transaction information for crypto assets (virtual currencies), this is a mechanism used by an unspecified number of participants to Consensus builds transaction information without a specific governing entity. It is very safe to prevent forgery of transaction information, but it requires a lot of calculations, so its disadvantage is that it takes a long time to complete the transaction when there are many participants.

7. Scalability problem

Scalability problem refers to the "scalability" problem that delays transaction processing.

Examples of term usage

Spiking gas prices have highlighted Ethereum’s scalability issues.

Details

Due to the nature of blockchain, there are processing delays due to the limited amount of transaction data that can be written in a block. Sending money can take a long time, which results in higher transaction fees. Bitcoin, the first cryptocurrency to be created, has been recognized as a special problem, but efforts to solve it have been implemented, such as leveraging other technologies such as the Lightning Network and developing new blockchains.

8. GAS fee

GAS fee is the (network) transaction fee on the Ethereum blockchain.

Examples of term usage

This week, there were multiple cases of high gas bills being paid on the Ethereum blockchain despite small remittances.

Details

The user-specified amount of GAS fee is a secondary reward. The virtual currency Ethereum (ETH) is used for payments. Because transactions with higher fees are processed first, GAS fees may increase as the number of transactions increases.

9. Liquidity Mining (Liquidity Mining)

Considering the provision of liquidity (currency pairs), liquidity mining refers to the granting of governance tokens in addition to interest to attract those who implement yield checks and balances .

Examples of term usage

Liquidity mining is accelerating and profitable.

Details

In liquidity mining, by storing a specific asset in a liquidity pool and providing liquidity that traders can buy and sell, the swap fee at the time can be used as Income earned. These liquidity mining originated from the largest decentralized exchange "Uniswap", and many liquidity mining contracts were born, such as Curve Finance and Balancer.

10. DeFi (Distributed Finance)

DeFi (Decentralized Finance) refers to financial services or systems that utilize blockchain and are provided without a central administrator.

Examples of term usage

Since June 2020, the DeFi market has developed rapidly.

Details

Abbreviation for "decentralized finance". Financial services provided by DeFi include issuing stable coins, lending currencies, and cryptocurrency exchanges. Many platforms use the Ethereum blockchain.

11. PoS (Proof of Stake)

PoS is a consensus algorithm that gives you the right to approve and generate new blocks based on the percentage (stake) of the virtual currency you own.

Examples of term usage

Ethereum co-founder Vitalik Buterin said that moving ETH’s consensus algorithm from PoW to PoS will improve security and scalability.

Details

Abbreviation for Proof of Stake. You can also consider the holding period of the virtual currency. It was born as an alternative to the “Proof-of-Work (PoW)” consensus algorithm, which requires high-performance computers to approve transactions and consumes large amounts of energy. If approved, you can receive newly issued virtual currency as a reward.

12. dApps

dApp is an application developed using open source blockchain.

Examples of term usage

South Korea’s largest Samsung Electronics app store “Galaxy Store” has started using Tron’s blockchain to process dApps.

Details

Abbreviation for "decentralized application", also known as "decentralized application" in Japanese. A major feature is that there is no centralized administrator. The most popular is the Ethereum blockchain, which is developing applications such as gaming and decentralized exchanges (DEX).

Ⅷ What are the related terms related to cryptocurrency (virtual currency) mining?

1. Lightning Network

Lightning Network is an off-chain technology that uses Layer 2 to eliminate Bitcoin’s transaction processing capabilities.

Examples of term usage

Cryptocurrency exchange Bitfinex plans to implement a Tether-based Lightning Network (USDT).

Details

If the Lightning Network is introduced, it will be possible to conduct transactions outside of crowded blockchains, resulting in faster transactions and lower fees. If transactions can be made faster and fees lower, micropayments can be made, which promises to create new products and services.

6. Mining Pool

A mining pool is an organized server created to collect the hashes of each miner and collaborate in mining.

Examples of term usage

Rewards earned in the mining pool by the virtual currency exchange Binance can be traded directly by Binance.

Details

In mining operations where scale is critical, a mechanism for multiple miners to work together to mine. Rewards are paid based on mining contributions.

7. Half-life

Half-life refers to the time when the mining rewards (=new issuance) of virtual currencies such as Bitcoin are reduced by half.

Examples of term usage

The cryptocurrency Bitcoin (BTC) reached its third half-life on May 12, 2020, with the mining reward dropping from 12.5 BTC to 6.25 BTC.

Details

Many virtual currencies have "issuance limits" to prevent inflation, and every half-life at certain intervals, the amount of new issuances will be reduced by half. This is also a noteworthy event unique to virtual currencies, as scarcity value increases significantly as supply decreases and prices tend to increase.

Ⅸ What is Bitcoin? The Origin of Bitcoin

1. Bitcoin:

Also known as “Bitcoin”, it is an online virtual currency that netizens You can use Bitcoin to purchase some virtual items, such as clothes, hats, equipment, etc. in online games. Some netizens also use it to purchase real items.

2. The origin of Bitcoin:

The concept of Bitcoin (BitCoin) was first proposed by Satoshi Nakamoto in 2009, and was designed and released based on Satoshi Nakamoto’s ideas open source software and the P2P network built on it. Bitcoin is a P2P form of digital currency. Peer-to-peer transmission means a decentralized payment system.

Unlike most currencies, Bitcoin does not rely on the issuance of a specific monetary institution. It is generated through a large number of calculations based on a specific algorithm. The Bitcoin economy uses a distributed database composed of many nodes in the entire P2P network to confirm All transactions are recorded, and cryptographic design is used to ensure the security of all aspects of currency circulation.

(9) Extended reading of terms in the Bitcoin circle:

The origin of Bitcoin:

Starting from the essence of Bitcoin, the essence of Bitcoin is actually It is a special solution generated by a bunch of complex algorithms. A special solution refers to a set of infinite (in fact, Bitcoin is finite) solutions that can be obtained by a system of equations. And every special solution can solve the equation and is unique.

Using RMB as an analogy, Bitcoin is the serial number of RMB. If you know the serial number on a certain banknote, you own the banknote. The mining process is to continuously seek special solutions to this system of equations through a huge amount of calculations. This system of equations is designed to have only 21 million special solutions, so the upper limit of Bitcoin is 21 million.

X What are the basic terms related to Bitcoin

Bitcoin client (wallet): It is the software that handles sending and receiving Bitcoins. The most popular one is the client downloaded from the bitcoin official website. There are some other options.
Wallet: has two meanings, 1. It refers to the Bitcoin client (the client generally refers to the desktop client; the wallet generally refers to the lightweight client or online wallet); 2. It refers to the storage of Bitcoin addresses. and private key files.
Bitcoin address: is a string such as "" that you can get from the recipient. Use the client to create an address and generate the corresponding private key.
Private key: In the context of Bitcoin, the private key is associated with the corresponding address (technically, the address is the hash value of the public key corresponding to the private key), and is stored at the bottom and Allows you to transfer Bitcoins owned by your current address. Please note that because Bitcoin uses the ECDSA encryption algorithm, it is able to generate the corresponding public key and address from the private key.
Transaction: A transaction refers to a message that notifies the entire Bitcoin network of the occurrence of a transaction, allowing the recipient to use the money and preventing the sender from double-spending.
