Ethereum transaction - <a href=以太坊eth交易”>

Ethereum transaction

On the Ethereum network we have two types of transactions:

  • Message calls
  • Contract creation

Transaction fields

Ethereum transaction - <a href=以太坊eth交易”>

Let’s go over transaction’s fields in a little more detail.

Nonce

Is a transaction count from the sender’s account. Every transaction that occurs needs to have a unique incrementing nonce. The first transaction you send from your account will have a nonce of zero.

Gas price

Is the price the sender is willing to pay per unit of a gas. Is a similar concept like miner fees in the Bitcoin. Ethereum uses gas to determine the reward miners received for executing contracts. The price set here is the incentive miners have to mine new transactions.

Gas limit

Specifies the maximum number of gas that the contract can spend. This is useful for a few reasons that we’ll go over it in a later section.

To

Specifies the recipient’s address.

Values

The amount of Ether you want send is shown in the value field.

Data, Init

Information used to record creation and execution of smart contrats.

Creating transactions

At this code I’ll make a transaction between two accounts. To do that, there’s a few main things that need happen.

First I need to bring in the dependencies and set up my connection between Web3 and Ganache.

web3.js

Makes possible the communication between an app and the ethereum blockchain.

Ganache

It’s a tool that allow us to use a local ethereum blockchain that preset 10 accounts with 100 ether each one.


以太坊eth网络上,我们有两种类型的事务:

以太坊eth交易

Ethereum transaction - <a href=以太坊eth交易”>

  • 消息调用
  • 合同创建

交易字段

让我们更详细地检查事务字段。

是发件人帐户中的交易计数。发生的每个事务都需要有一个唯一的递增nonce。您从帐户发送的第一笔交易的nonce为零。

现货

是发送方愿意为每单位天然气支付的价格。类似于BTC中的矿工费用。以太坊eth使用天然气来确定矿工因执行合同而获得的报酬。这里设定的价格是激励矿商挖掘新交易的动力。

天然气价格

指定合同可使用的最大天然气数量。这很有用,因为有几个原因,我们将在后面的一节中讨论。

天然气限额

指定收件人的地址。

要发送的乙醚量显示在值字段中。用于记录智能合同的创建和执行的信息。

在这段代码中,我将在两个帐户之间进行交易。要做到这一点,需要做一些主要的事情。

数据,初始化

首先,我需要引入依赖项,并在Web3和Ganache之间建立连接。

创建交易

使应用程序和以太坊eth区块链blockchain之间的通信成为可能。

这是一个允许我们使用本地以太坊eth区块链blockchain的工具,它预设了10个账户,每个账户100个以太坊eth
