⑴ 比特币跟区块链是什么关系

可以参看下我自己写的文章

三分钟告诉你什么是区块链！

区块链，让全名参与记账，全名记账更稳定，由于系统中并没有特定记账人，系统中任意节点失联或者被摧毁都不会影响系统的运行。（你是否曾经上某个网页遇见错误404代码？）全名记账更安全！系统规定相同数量最多的账本是真账本，少部分和其他不一致的账本即为假账本，这让具有足够多节点的区块链很难被攻击或者被篡改，这些节点分布在互联网的任意角落，除非你是上帝能够控制全世界大部分电脑否则无法篡改。因此区块链被认为有史以来最安全的数据管理方式。全名记账更高效，由于没有中心化的中介机构存在，完全通过预先设定的程序自动运行能够极大降低成本和提高效率并且确保账本记录过程和内容公开透明。

比特币，只是区块链技术方案在支付领域的一个实验性应用，区块链还可以用于更广阔的领域比如医疗、物联网、安全认证、社交以及人工智能等领域都有它的身影。

《经济学人》称区块链为”信任的机器”，认为它对于全球金融甚至是社会结构都会产生巨大且深远的影响。如果用一句话总结，区块技术是在多方无需互信环境下通过密码学技术让系统中所有参与方协作记录日志方式。

这，就是区块链！

⑵ 区块链和比特币是什么关系

很多人有一个误解以为比特币就是区块链，其实是非常错误的。比特币只是区块链技术的一种应用，把区块链比作互联网，比特币只是其中的一个APP，区块链的应用场景还非常非常大。推荐到千聊或喜马拉雅上学习 gojoy区块链网上大学的区块链商业革命，这些讲的很透彻又通俗易懂！

⑶ 区块链和比特币的区别是什么

‍‍‍‍

周边有不少朋友，提起区块链，就认为是比特币。这其实是有失偏颇的。就像：说起木头来，就认为是桌子一样。

其实比特币和区块链根本不是一个东西，区块链只是比特币背后的核心实现技术。区块链不仅可以应用于比特币，还可以应用于电子票据、股权登记、奢侈品跟踪防伪等多个领域。

比特币，作为无核心机构管理、分布式自主运营的系统，经过长达7年多的稳健运行，成功的实现了数字货币的全球支付和流通功能，充分体现了区块链技术独特优势。

总体来说,比特币是区块链的一种成功应用,也是第一条稳健运行的区块链。

未来随着区块链研究的不断深入和社会资本的不断推动，作为一种基础的应用技术，区块链必将在社会的各个行业中发挥更加重要的作用。

⑷ 区块链和比特币之间是什么关系

区块链技术是比特币的底层技术，也是比特币的核心与基础架构。比特币一直在没有任何中心化机构运营和管理的情况下运行，后来比特币技术被抽象提取出来，称之为区块链技术，或者分布式账本技术。

(4)比特币和区块链合约扩展阅读：

区块链技术应用于数字货币的弊端：

一是“去中心化”没有流通管理机构。区块链技术本质上是个分布式数据库系统，逻辑结构为单向链表，设计模式基于P2P网 络，这就决定了基于区块链技术的虚拟货币没有统一的中心管控系统。

二是数量供给难以有效调控。基于区块链技术的虚拟货币发行量是固定的，而根据费雪方程，全社会一定时期一定价格水平下的总交易量与所需要的名义货币量具有一定比例关系，而恒定的货币量显然不能满足不断增长的社会商品价格总额要求。

三是“挖矿机制”难以创造公认价值。比特币本身没有价值，也没有国家信用支撑。有观点认为，“通过不断消耗算力与能源为虚拟货币注入价值”，但为寻找一个符合要求的hash值而消耗百万亿次计算，这显然不是最有效率的选择。

四是生产者和先期持有者易获高额“铸币税”。任何一种基于区块链技术的虚拟货币，在其发展的初始阶段都为少数人持有。以比特币为例，最初比特币只是少数人游戏的产物，2010年5月发生的第一次比特币购物是1万BTC购买了25美元的比萨饼，同年7月完成的第一笔比特币交易是0.04美元/BTC。

⑸ 区块链和比特币是什么关系

区块链技术是比特币的底层技术，在早期并没有太多人注意到比特币的底层技术。但是当比特币在没有任何中心化机构运营和管理的情况下，在多年里非常稳定的运行，并且没有出现过任何问题。所以被很多人注意到。

⑹ 比特币与区块链什么关系

简单来说：

1、比特币是一种数字货币，区块链是一种技术。

2、区块链是比特币的底层技术，而比特币则是区块链技术的第一个应用；作为国家支持并大力发展的区块链技术未来将广泛应用于各行各业。

3、区块链技术并不是一种新技术，而是一种思维新逻辑，只不过把很多之前并不相关的算法技术重新排列组合在一起而已。

4、区块链，就是一个区块和一个区块相连接，成千上万个区块就形成了一条链；而要连接下一个区块，就需要计算出算法答案（挖矿），而挖矿的奖励就是比特币。

⑺ 比特币，区块链和ICO分别是什么 有什么区别

比特币是中本聪于2009年提出的一种虚拟数字货币，特点是没有中心化的发行机构，总量固定，为2100万枚，而且不是一次性发行，需要由矿工挖矿产生。由于是去中心化的结构，信任就需要依靠密码学和共识机制技术来达到。
区块链是比特币衍生出来的一种通用技术，它实现了去中心化的数据库模型，比特币可以规为区块链1.0，因为它没有智能合约的概念。区块链关键技术就包括密码学加解密和共识机制，区块链一般是用来和具体业务逻辑相结合，这就需要依赖智能合约了，智能合约提供了不受人为干扰的执行模式。
ICO首次币发行，源自股票市场的首次公开发行（IPO）概念，是区块链项目首次发行代币，募集比特币、解决以太坊等通用数字货币的行为。

⑻ 区块链和比特币有什么区别

区块链是技术，比特币是虚拟货币。
区块链技术是一种去中心化的共识机制，来维护一个完整的、分布式的、不可篡改的账本数据库的技术。它能够让区块链中的参与者在无需建立信任关系的前提下实现一个统一的账本系统。
未来区块链会应用于任何领域，给人类生活带来极大影响。区块链技术被视为下一代价值互联网的主要协议之一，任何缺乏信任的生产生活领域，区块链技术都将有用武之地。从数字货币到证券与金融合约、医疗、游戏、人工智能、智能合约、物联网、身份验证、资产交易、电子商务、社交通讯、文件储存等等领域都可以进行广泛应用。
医疗方面
用区块链技术对个人医疗记录进行保存，就有了个人医疗的历史数据，可以理解为区块链上的电子病历。未来看病或对自己的健康做规划就有数据可供使用，而这个数据真正的掌握者是患者自己，而不是医院或某个第三方机构。另外，这些数据有很强的隐私性，使用区块链技术也有助于保护患者隐私。
支付系统
与现有的传统支付体系相比，区块链技术能够避开繁杂的系统，在交易双方之间直接进行，不涉及中间机构，即使部分网络瘫痪也不会影响整个系统运行。这种方式有着低价、迅速的特点，而且无需中间手续费。
银行业
作为一种数字化，安全防干扰的账户，区块链实现了银行业的核心功能：即价值的安全储存和转移中心。国际上一些嗅觉较为敏锐的银行已开始积极筹谋，投身区块链研究和应用大军中，以期在未来的激烈竞争中获取主动权。
区块链身份认证
区块链具有人人都可查阅的特性，每个人都可以在任何一个有网络的地方，查询区块信息，高透明的特性也让区块链充满魅力。未来身份证和户口本基本不需要了，因为每一个身份信息都可以写入区块链里，当需要验证信息的时候，只需要查阅就可以找到。
选举
基于在区块链上的投票交易，可以确认没有票被修改或删除，不会有不正当投票。
房地产
区块链技术可改变房地产市场的运作方式，它能合并许多复杂的流程和房地产公司通常要处理的事例，加快交易进程、减少欺诈行为，为每一个参与者提供更透明、安全的交易。提供了一个途径去实现无纸化和快速交易的需求。
证券发行与交易
一般股票等证券交易出现各类错误的概率过高，需要人工纠错，因而延长了交易结算所需的时间。通过分布式账本进行交易，可以实现整个流程的自动化，提高安全性和效率。交易方身份、交易量等信息被实时记录在区块链上，加上公开透明、可追踪的系统。有利于证券发行者和监管部门进行市场维护，可减少暗箱操作、内幕交易等的发生。
区块链在相对封闭、存在多方信任问题，以及承载价值传递的场景中，有着独特的技术优势，也展示出独特的魅力，具有很大的应用想象空间。在当前阶段，区块链在部分场景中很值得探索。

⑼ 比特币与区块链有什么关系

比特币的横空出世，让一项新技术——区块链，走入大众视野。比特币和区块链到底 有什么关系呢？最简单的理解就是：区块链是比特币的底层技术，比特币是区块链的第一 代应用，所以我们常常看到有这样一种说法，说“比特币代表着区块链 1.0 时代”。

比特币被视为区块链技术的第一代应用，也是其代码测试最彻底的一项应用。但是， 如果没有比特币，可能现在不会有这么多人知道区块链这个事情。可以说，比特币让区块 链这门技术的“曝光率”大大提高。

之后，人们逐渐发现，区块链的应用价值远不止比特币这一种，而是能够应用到许多 行业，解决许多行业的痛点；而区块链的思想还能为金融领域提供许多借鉴，这才是区块 链真正爆发的原因。

⑴ What is the relationship between Bitcoin and blockchain

You can refer to the article I wrote myself

I will tell you what blockchain is in three minutes!

Blockchain allows full names to participate in bookkeeping, and full-name bookkeeping is more stable. Since there is no specific bookkeeper in the system, any node in the system loses contact or is blocked. Destroying it will not affect the operation of the system. (Have you ever encountered an error 404 code on a certain webpage?) Full-name accounting is safer! The system stipulates that the ledger with the largest number of the same number is the true ledger, and a small number of ledgers that are inconsistent with others are false ledgers. This makes it difficult for a blockchain with enough nodes to be attacked or tampered with. These nodes are distributed in any corner of the Internet. Unless you are God and can control most of the computers in the world, you cannot tamper with them. Therefore, blockchain is considered the most secure way of data management ever. Full-name accounting is more efficient. Since there is no centralized intermediary agency, fully automatic operation through preset programs can greatly reduce costs and improve efficiency, and ensure that the accounting recording process and content are open and transparent.

Bitcoin is just an experimental application of blockchain technology solutions in the payment field. Blockchain can also be used in broader fields such as medical care, Internet of Things, security authentication, social networking, and artificial intelligence. It has its presence in every field.

"The Economist" calls blockchain a "trust machine" and believes that it will have a huge and far-reaching impact on global finance and even social structure. To sum up in one sentence, block technology is a way for all participants in the system to collaborate and record logs through cryptography technology in an environment where multiple parties do not need mutual trust.

This is the blockchain!

⑵ What is the relationship between blockchain and Bitcoin?

Many people have a misunderstanding that Bitcoin is blockchain, but this is actually very wrong. Bitcoin is just an application of blockchain technology. Blockchain is compared to the Internet. Bitcoin is just one of the APPs. The application scenarios of blockchain are still very, very large. It is recommended to go to Qianliao or Ximalaya to study the blockchain business revolution of gojoy Blockchain Online University. These lectures are very thorough and easy to understand!

⑶ What is the difference between blockchain and Bitcoin?

‍‍‍‍

There are many friends around me who think of blockchain as Bitcoin. This is actually biased. Just like: when we talk about wood, we think of it as a table.

In fact, Bitcoin and blockchain are not the same thing at all. Blockchain is just the core implementation technology behind Bitcoin. Blockchain can be applied not only to Bitcoin, but also to electronic bills, equity registration, luxury goods tracking and anti-counterfeiting, and many other fields.

Bitcoin, as a system without core institutional management and distributed autonomous operation, has successfully realized global payment and digital currency after more than 7 years of stable operation. The circulation function fully reflects the unique advantages of blockchain technology.

Generally speaking, Bitcoin is a successful application of blockchain and the first blockchain to operate stably.

In the future, as blockchain research continues to deepen and social capital continues to promote, as a basic application technology, blockchain will play a more important role in various industries in society.

⑷ What is the relationship between blockchain and Bitcoin?

Blockchain technology is the underlying technology of Bitcoin and is also the core and infrastructure of Bitcoin. Bitcoin has been operating without any centralized organization operation and management. Later, Bitcoin technology was abstracted and called blockchain technology, or distributed ledger technology.

(4) Extended reading on Bitcoin and blockchain contracts:

Disadvantages of applying blockchain technology to digital currencies:

< p>First, "decentralization" does not have a circulation management agency. Blockchain technology is essentially a distributed database system, the logical structure is a one-way linked list, and the design model is based on P2P network, which determines that virtual currencies based on blockchain technology do not have a unified central management and control system.

Second, quantity supply is difficult to effectively control. The issuance amount of virtual currency based on blockchain technology is fixed. According to the Fisher equation, the total transaction volume of the whole society at a certain price level in a certain period has a certain proportional relationship with the required nominal currency amount, and a constant currency amount is obviously It cannot meet the ever-increasing total price requirements of social commodities.

Third, the “mining mechanism” is difficult to create recognized value. Bitcoin itself has no value and is not supported by national credit. Some people believe that "injecting value into virtual currency by continuously consuming computing power and energy", but consuming trillions of calculations to find a hash value that meets the requirements is obviously not the most efficient option.

Fourthly, producers and early holders can easily obtain high "seigniorage". Any virtual currency based on blockchain technology is held by a small number of people in the initial stage of its development. Take Bitcoin as an example. Initially, Bitcoin was just a product of a few people’s games. The first Bitcoin purchase that occurred in May 2010 was a $25 pizza purchased with 10,000 BTC. The first Bitcoin transaction was completed in July of the same year. It is $0.04/BTC.

⑸ What is the relationship between blockchain and Bitcoin?

Blockchain technology is the underlying technology of Bitcoin. In the early days, not many people paid attention to the underlying technology of Bitcoin. But when Bitcoin is operated and managed without any centralized organization, it has been operating very stably for many years and hasAnd there have been no problems. So it was noticed by many people.

⑹ What is the relationship between Bitcoin and blockchain?

In simple terms:

1. Bitcoin is a digital currency, and blockchain is a technology.

2. Blockchain is the underlying technology of Bitcoin, and Bitcoin is the first application of blockchain technology; as a state-supported and vigorously developed blockchain technology, it will be widely used in the future All walks of life.

3. Blockchain technology is not a new technology, but a new logic of thinking. It just rearranges and combines many previously unrelated algorithmic technologies.

4. Blockchain is a block connected to a block. Thousands of blocks form a chain. To connect the next block, you need to calculate the algorithm. The answer (mining), and the reward for mining is Bitcoin.

⑺ What are the differences between Bitcoin, blockchain and ICO

Bitcoin is a virtual digital currency proposed by Satoshi Nakamoto in 2009. It is characterized by no center. It is a specialized issuing institution with a fixed total amount of 21 million pieces. It is not a one-time issuance and needs to be mined by miners. Since it is a decentralized structure, trust needs to rely on cryptography and consensus mechanism technology to achieve it.
Blockchain is a general technology derived from Bitcoin. It implements a decentralized database model. Bitcoin can be classified as blockchain 1.0 because it does not have the concept of smart contracts. The key technologies of blockchain include cryptography encryption and decryption and consensus mechanism. Blockchain is generally used to combine with specific business logic, which requires reliance on smart contracts. Smart contracts provide an execution mode that is free from human interference.
ICO initial coin offering, derived from the concept of initial public offering (IPO) in the stock market, is the first act of a blockchain project to issue tokens, raise Bitcoin, and solve general digital currencies such as Ethereum.

⑻ What is the difference between blockchain and Bitcoin?

Blockchain is technology and Bitcoin is virtual currency.
Blockchain technology is a decentralized consensus mechanism that maintains a complete, distributed, and non-tamperable ledger database. It allows participants in the blockchain to implement a unified ledger system without establishing a trust relationship.
In the future, blockchain will be applied in any field and will have a great impact on human life. Blockchain technology is regarded as one of the main protocols for the next generation of value Internet. Blockchain technology will be useful in any area of ​​production and life that lacks trust. It can be widely used in fields ranging from digital currency to securities and financial contracts, medical treatment, games, artificial intelligence, smart contracts, Internet of Things, identity verification, asset trading, e-commerce, social communication, file storage and other fields.
Medical aspects
Using blockchain technology to save personal medical records, you will have historical data of personal medical care, which can be understoodFor electronic medical records on the blockchain. Data will be available for future medical treatment or health planning, and the real owner of this data is the patient himself, not the hospital or a third-party organization. In addition, these data have strong privacy, and the use of blockchain technology can also help protect patient privacy.
Payment System
Compared with the existing traditional payment system, blockchain technology can avoid complicated systems and conduct transactions directly between the two parties without involving intermediaries. Even if part of the network is paralyzed, it will not Will affect the operation of the entire system. This method is low-cost, fast, and requires no intermediate handling fees.
Banking
As a digital, secure and tamper-proof account, blockchain realizes the core function of the banking industry: a secure storage and transfer center for value. Some banks with a keen sense of smell in the world have begun to actively plan and join the blockchain research and application army, hoping to gain the initiative in the fierce competition in the future.
Blockchain Identity Authentication
Blockchain has the feature that everyone can check it. Everyone can query block information anywhere there is a network. The highly transparent feature also makes the block The chain is full of charm. In the future, ID cards and household registration books will be basically unnecessary, because every identity information can be written into the blockchain. When you need to verify information, you only need to look it up to find it.
Election
Based on voting transactions on the blockchain, it can be confirmed that no votes have been modified or deleted, and there will be no improper votes.
Real Estate
Blockchain technology can change the way the real estate market operates. It can merge many complex processes and cases that real estate companies usually deal with, speed up transaction processes, reduce fraud, and provide benefits for every participant. Provide more transparent and secure transactions. Provides a way to achieve paperless and fast transaction needs.
Securities issuance and trading
General stock and other securities transactions have a high probability of various errors, requiring manual error correction, which prolongs the time required for transaction settlement. Transactions through distributed ledgers can automate the entire process and improve security and efficiency. The identity of the transaction party, transaction volume and other information are recorded on the blockchain in real time, coupled with an open, transparent and traceable system. It is conducive to market maintenance by securities issuers and regulatory authorities, and can reduce the occurrence of black-box operations, insider trading, etc.
Blockchain has unique technical advantages, shows unique charm, and has great application imagination in scenarios where it is relatively closed, has multi-party trust issues, and carries value transfer. At the current stage, blockchain is worth exploring in some scenarios.

⑼ What is the relationship between Bitcoin and blockchain?

The emergence of Bitcoin has brought a new technology, blockchain, into the public eye. What is the relationship between Bitcoin and blockchain? The simplest understanding is: blockchain is the underlying technology of Bitcoin, and Bitcoin is the first generation application of blockchain, so we often see such aThere is a saying that "Bitcoin represents the blockchain 1.0 era."

Bitcoin is regarded as the first generation application of blockchain technology, and it is also the application with the most thorough code testing. However, without Bitcoin, not so many people may know about blockchain now. It can be said that Bitcoin has greatly increased the “exposure” of blockchain technology.

Afterwards, people gradually discovered that the application value of blockchain is far beyond Bitcoin, but can be applied to many industries and solve the pain points of many industries; and the idea of ​​blockchain can also Providing many references for the financial field is the reason why blockchain really explodes.
