① 从本质上讲区块链技术中的智能合约是做什么的

就是一段状态转移代码。
比如我的账户A 有100块钱。运行合约B后，变成了80块钱。这个合约就是将100这个状态转换成了80。合约本身也是一个帐户，外部的时间（交易，事件）也能触发状态转移。

② 智能合约是什么

智能合约"(smart contract)这个术语至少可以追溯到1995年，是由多产的跨领域法律学者尼克·萨博(Nick Szabo)提出来的。他在发表在自己的网站的几篇文章中提到了智能合约的理念。他的定义如下:
"一个智能合约是一套以数字形式定义的承诺(promises)，包括合约参与方可以在上面执行这些承诺的协议。"
让我们更加详细地探讨他的定义的意思。
承诺
一套承诺指的是合约参与方同意的(经常是相互的)权利和义务。这些承诺定义了合约的本质和目的。以一个销售合约为典型例子。卖家承诺发送货物，买家承诺支付合理的货款。
数字形式
数字形式意味着合约不得不写入计算机可读的代码中。这是必须的，因为只要参与方达成协定，智能合约建立的权利和义务，是由一台计算机或者计算机网络执行的。
更进一步地说明:
(1)达成协定
智能合约的参与方什么时候达成协定呢?答案取决于特定的智能合约实施。一般而言，当参与方通过在合约宿主平台上安装合约，致力于合约的执行时，合约就被发现了。
(2)合约执行
"执行"的真正意思也依赖于实施。一般而言，执行意味着通过技术手段积极实施。
(3)计算机可读的代码
另外，合约需要的特定"数字形式"非常依赖于参与方同意使用的协议。
协议
协议是技术实现(technical implementation)，在这个基础上，合约承诺被实现，或者合约承诺实现被记录下来。选择哪个协议取决于许多因素，最重要的因素是在合约履行期间，被交易资产的本质。
再次以销售合约为例。假设，参与方同意货款以比特币支付。选择的协议很明显将会是比特币协议，在此协议上，智能合约被实施。因此，合约必须要用到的"数字形式"就是比特币脚本语言。比特币脚本语言是一种非图灵完备的、命令式的、基于栈的编程语言，类似于Forth。

③ 以太坊智能合约是什么

以太坊是一个分布式的计算平台。它会生成一个名为Ether的加密货币。程序员可以在以太坊区块链上写下“智能合约”，这些以太坊智能合约会根据代码自动执行。

以太坊是什么？
以太坊经常与比特币相提并论，但情况却有所不同。比特币是一种加密货币和分布式支付网络，允许比特币在用户之间转移。

相关：什么是比特币？它是如何工作的？

以太坊项目有更大的目标。正如Ethereum网站所说，“以太坊是一个运行智能合约的分布式平台”。这些智能合约运行在“以太坊虚拟机”上，这是一个由所有运行以太网节点的设备组成的分布式计算网络。

“分布式平台”部分意味着任何人都可以建立并运行以太坊节点，就像任何人都可以运行比特币节点一样。任何想要在节点上运行“智能合约”的人都必须向Ether中的这些节点的运营商付款，这是一个与以太坊相关的加密货币。因此，运行以太网节点的人提供计算能力，并在以太网中获得支付，这与运行比特币节点的人提供哈希能力并以比特币支付的方式类似。

换句话说，虽然比特币仅仅是一个区块链和支付网络，但以太坊是一个分布式计算网络，其区块链可以用于许多其他事情。以太坊白皮书中提供了详细信息。

以太是什么？
以太网是与以太坊区块链相关的数字标记（或者说就是加密货币）。换句话说，以太是代币，以太坊是平台。但是，现在人们经常交替使用这些术语。例如，Coinbase允许你购买以太坊代币（Ethereum），即代表以太币代币。

这在技术上就是“altcoin”，这实际上意味着一个非比特币加密货币。和比特币一样，Ether也受到分布式区块链支持 - 在这种情况下是以太坊区块链。

想要在以太坊区块链上创建应用程序或以太坊智能合约的开发人员需要以太网代币来支付节点来托管它，而基于以太坊的应用程序的用户可能需要以太网来支付这些应用程序中的服务费用。人们也可以在以太坊网络之外销售服务，并接受以太网支付，或者可以在交易所以现金形式出售以太币代币 - 就像比特币一样

④ 比特币合约交易什么意思

合约交易是对比特币莱特币期货合约交易的统称。
2013年6月，796交易所在比特币业内率先开发出了比特币周交割标准期货—T+0双向交易虚拟商品作押易货合约（合约交易）。
合约交易的出现结束了此前比特币不能做空的历史，开启了比特币衍生品市场发展繁荣的序幕。

⑤ 区块链技术中的智能合约是什么

重庆金窝窝网络分析：智能合约功能是指电子合约与区块链技术结合，合约条款以计算机语言而非法律语言记录，当一个预先编好的条件被触发时，智能合约执行相应的合同条款。

⑥ 比特币ETH是什么意思

比特币是BTC，而ETH是以太坊。
比特币（Bitcoin）的概念最初由中本聪在2008年11月1日提出，并于2009年1月3日正式诞生[1]。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。
以太坊（英文Ethereum）是一个开源的有智能合约功能的公共区块链平台，通过其专用加密货币以太币（Ether，简称“ETH”）提供去中心化的以太虚拟机（EthereumVirtualMachine）来处理点对点合约。

① Essentially, what does a smart contract in blockchain technology do

It is a piece of state transfer code.
For example, my account A has 100 yuan. After running contract B, it becomes 80 yuan. This contract converts the state of 100 into 80. The contract itself is also an account, and external times (transactions, events) can also trigger state transfers.

② What is a smart contract?

The term "smart contract" dates back to at least 1995 and was coined by Nick Szabo, a prolific interdisciplinary legal scholar. ). He mentioned the concept of smart contracts in several articles published on his website. His definition is as follows:
"A smart contract is a set of promises defined in digital form. Includes an agreement on which the parties to the contract can execute these commitments. "
Let's explore what his definition means in more detail.
Commitments
A set of commitments refers to the (often mutual) rights and obligations agreed upon by the parties to a contract. These commitments define Understand the nature and purpose of the contract. Take a sales contract as a typical example. The seller promises to deliver the goods, and the buyer promises to pay a reasonable price.
Digital form
Digital form means that the contract must be written in a computer-readable format in the code. This is necessary because as long as the participants reach an agreement, the rights and obligations established by the smart contract are executed by a computer or computer network.
Further explanation:
(1 ) reaches an agreement
When do the participants of a smart contract reach an agreement? The answer depends on the specific smart contract implementation. Generally speaking, when the participants commit to the execution of the contract by installing the contract on the contract host platform, The contract is discovered.
(2) Contract execution
The true meaning of "execution" also depends on implementation. Generally speaking, execution means active implementation through technical means.
(3) Computer-readable code
In addition, the specific "digital form" required by the contract is very dependent on the protocol that the parties agree to use.
Protocol
The protocol is a technical implementation (technical implementation), on this basis On, the contractual promise is fulfilled, or the fulfillment of the contractual promise is recorded. Which agreement is chosen depends on many factors, the most important of which is the nature of the assets being traded during the performance of the contract.
Again, take the sales contract as an example. Assume that the parties agree to pay the price in Bitcoin. The protocol chosen will obviously be the Bitcoin protocol, on which the smart contract is implemented. Therefore, the "digital form" that the contract must use is BitcoinCoin scripting language. The Bitcoin Script Language is a non-Turing complete, imperative, stack-based programming language similar to Forth.

③ What is the Ethereum smart contract?

Ethereum is a distributed computing platform. It generates a cryptocurrency called Ether. Programmers can write "smart contracts" on the Ethereum blockchain, and these Ethereum smart contracts automatically execute based on the code.

What is Ethereum?
Ethereum is often compared to Bitcoin, but the situation is different. Bitcoin is a cryptocurrency and distributed payments network that allows Bitcoins to be transferred between users.

Related: What is Bitcoin? How does it work?

The Ethereum project has bigger goals. As the Ethereum website says, "Ethereum is a distributed platform for running smart contracts." These smart contracts run on the “Ethereum Virtual Machine,” a distributed computing network made up of all devices running Ethereum nodes.

The “distributed platform” part means that anyone can set up and run an Ethereum node, just like anyone can run a Bitcoin node. Anyone who wants to run "smart contracts" on a node must pay the operators of these nodes in Ether, a cryptocurrency associated with Ethereum. So someone running an Ethereum node provides computing power and is paid in Ether, similar to how someone running a Bitcoin node provides hashing power and is paid in Bitcoin.

In other words, while Bitcoin is just a blockchain and payments network, Ethereum is a distributed computing network whose blockchain can be used for many other things. Details are provided in the Ethereum white paper.

What is ether?
Ether is the digital token (or cryptocurrency) associated with the Ethereum blockchain. In other words, Ether is the token and Ethereum is the platform. However, people now often use these terms interchangeably. For example, Coinbase allows you to buy Ethereum, which stands for Ethereum tokens.

This is technically an "altcoin", which actually means a non-Bitcoin cryptocurrency. Like Bitcoin, Ether is also supported by a distributed blockchain - in this case the Ethereum blockchain.

Developers who want to create an application or Ethereum smart contract on the Ethereum blockchain will need Ether tokens to pay nodes to host it, while users of Ethereum-based applications may Ethernet is required to pay for services in these applications. People can also sell services outside the Ethereum network and accept Ether payments, or Ethereum tokens can be sold for cash on exchanges - just like Bitcoin

④What does Bitcoin contract trading mean?

Contract trading is the collective name for Bitcoin Litecoin futures contract trading.
In June 2013, 796 Exchange took the lead in the Bitcoin industry to develop the Bitcoin weekly delivery standard futures-T+0 two-way trading virtual commodity pledged barter contract (contract transaction).
The emergence of contract trading ended the previous history that Bitcoin could not be shorted, and opened the prelude to the development and prosperity of the Bitcoin derivatives market.

Chongqing Jinwowo Network Analysis: The smart contract function refers to the combination of electronic contracts and blockchain technology. The contract terms are recorded in computer language rather than legal language. When a pre-programmed condition is triggered When the smart contract executes the corresponding contract terms.

⑥ What does Bitcoin ETH mean?

Bitcoin is BTC, and ETH is Ethereum.
The concept of Bitcoin was first proposed by Satoshi Nakamoto on November 1, 2008, and was officially born on January 3, 2009[1]. The open source software designed and released based on Satoshi Nakamoto's ideas and the P2P network built on it. Bitcoin is a P2P virtual encrypted digital currency. Peer-to-peer transmission means a decentralized payment system.
Ethereum (English Ethereum) is an open source public blockchain platform with smart contract functions. It provides a decentralized Ethereum Virtual Machine (EthereumVirtualMachine) through its dedicated cryptocurrency Ether (ETH). ) to handle peer-to-peer contracts.
