A. 如何看待以太坊ETH2.0

我个人不是特别看好以太坊2.0。

以目前以太坊的发展情况来看，以太坊已经成为了世界上最大的一条公链，这点毫无疑问。伴随着以太坊得进一步发展，我们会发现区块链行业也取得了长足的进步。

一、我先讲一下关于目前以太坊的现状。

以太坊在这一次牛市中非常亮眼，换而言之，这一次的牛市就是因为以太坊上面的应用而拉起的。目前的以太坊有几个困境：第1个困境是交易费率太高，吓跑了很多人。第2个困境是交易速度太慢，网络拥堵问题非常严重。第3个困境是交易相对繁琐，其他公链显然要优于以太坊。这正是以太坊需要破局的地方，当以太坊升级到2.0以后，这些问题都会相应解决。

C. linux/centos如何查看网卡是100M还是1000M

可以使用ethtool命令进行查看，使用格式ethtool 网络接口名。

以下为例，eth0为网卡名，使用ifconfig查看当前使用的网卡。

Speed表示网卡带宽，Duplex表示工作模式，Supported link modes表示支持的工作模式。

(3)ETH全节点高度查看扩展阅读：

ethtool命令的其它用法：

1、查询网络端口位置：ethtool -p ethX

这个命令多用于管理多网口的服务器主机，由于背板的网络端口数量大，有时候不知道那个物理端口对应eth0或其他设备号，我们就可以使用这个命令来查询。

用法：ethtool -p eth0

效果：设备号eth0对应的物理端口的两个指示灯会闪烁

2、修改网络端口速率：ethtool -s

这个命令多用于手工设置网络速率，一般千兆网卡支持10|100|1000三个速率，单位是Mbps。

用法：ethtool -s eth0 speed 1000 plex full autoneg off

效果：将设备号eth0对应的物理端口设置为速率为1000Mbps，全双工工作模式，同时关闭自动协商。

D. 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。

F. WINDOWS下ETH本地节点挖矿

ETH 挖矿主要是使用显卡来挖矿。因此你需要一台拥有以下设备的PC：
显卡、主板、电源、CPU、内存、硬盘（推荐 60G 以上 SSD）、延长线、转接线等。
其中显卡决定挖矿的速度，主板、电源在很大程度上决定了矿机运行的稳定程度。

G. 什么是ETC/以太坊经典

以太经典（ETC）简史

以太经典始于一个不幸的事件。

2016年5月，去中心化自治组织(DAO)举行了一次代币销售，目标是建立一个基于区块链的风险投资，以资助Ethereum生态系统内未来的去中心化应用(DApps)。

基本上，DAO是一个去中心化方式运作的复杂的智能合约–当条件满足时自动在多方之间执行任务的计算机代码。

尽管其有着雄心勃勃的目标以及成功的代币销售，DAO的代码却有一个重大漏洞，使得攻击者可以从去中心化组织中窃取ETH。

攻击者在2016年6月利用这一漏洞，引发了臭名昭著的DAO黑客事件，恶意窃取了大约价值5000万美元的ETH。

毋庸置疑，DAO黑客事件曾震惊了Ethereum社区，也使得ETH价格从20美元跌至13美元。

在DAO黑客事件发生后，Ethereum社区不得不从三个选项中选择。

什么都不做，努力承受攻击带来的后果；或

启动软分叉，收回资金；或

部署一个硬分叉来恢复丢失的ETH。

软分叉和硬分叉都是重大的网络升级。然而，软分叉允许未升级的用户和升级后的用户相互交流，而硬分叉则不能向后兼容以前的版本。

由于开发人员意识到部署软分叉会使网络受到分布式拒绝服务（DDoS）攻击，Ethereum社区决定发起硬分叉，以恢复在DAO黑客攻击中损失的资金。

虽然这一方案得到了大多数人的支持，但Ethereum社区中的一小部分人却表示反对，他们认为 “代码即律法”，区块链网络应该是不可改变的。

由于双方未能在解决方案上达成一致，最终导致了Ethereum区块链的分裂。

那些试图找回丢失的ETH的人选择了硬分叉，开启了我们今天所熟知的Ethereum（ETH）区块链，而另一群人则留在了最初的Ethereum Classic（ETC）链上。

以太经典解决了那些问题？

以太经典（ETC）是一个允许开发者部署智能合约和DApps的区块链平台。

虽然这个功能与Ethereum（ETH）的功能相同，但ETC区块链有两个主要区别。

首先，Ethereum Classic社区反对篡改分布式账本，支持“区块链网络不能也不该被修改”的观点。

其次，虽然ETH总供应量没有硬性上限，但以太经典采用恒定供应的货币政策，最多允许创建2.3亿个ETC。

作为一个加分项，以太经典在去年启动了Atlantis硬分叉，以增加与Ethereum的交互性，并通过zk-SNARKS提高交易的隐私保护程度。

以太经典ETC推荐的交易平台

火币、OKEX、AAX等。

I. 虚拟货币ETH全部被买完了那么还有多少上涨空间

决定ETH等虚拟货币价格的有以下几个方面：1，使用频率，2，实际用途，3，参与买卖的人数。

至于还有多少上涨空间，以太坊目前价格为6600左右，前段时间由于使用以太坊私募频发，导致以太坊涨到了10000多，以太坊是智能合约，基于以太坊开发的各种代币不计其数，所以作为智能合约的底层公有链他的前景是随着区块链的热度而变化的，不过也正是由于前段时间，使得以太坊的缺点暴露出来，主链拥堵，手续费死贵等，发展已经接近于瓶颈，所以他的上涨空间在于开发者是否可以针对缺点改善主链环境，至于参与人数，现在不是大问题，多关注开发者目前的开发进度，专注于做事情的话，前途无量。

目前可以交易以太坊的网站有：BtcTrade国际站，火币，币安等

A. How to view Ethereum ETH2.0

I personally am not particularly optimistic about Ethereum 2.0.

Judging from the current development of Ethereum, there is no doubt that Ethereum has become the largest public chain in the world. As Ethereum develops further, we will find that the blockchain industry has also made great progress.

1. Let me first talk about the current status of Ethereum.

Ethereum is very prominent in this bull market. In other words, this bull market is caused by the applications on Ethereum. The current Ethereum has several dilemmas: The first dilemma is that the transaction fee is too high, which scares away many people. The second dilemma is that the transaction speed is too slow and the network congestion problem is very serious. The third dilemma is that transactions are relatively cumbersome, and other public chains are obviously better than Ethereum. This is where Ethereum needs to break. When Ethereum is upgraded to 2.0, these problems will be solved accordingly.

B. Bitcoin is now basically mining nodes, full nodes and spv nodes. Are the current nodes of Ethereum classified?

C. How to check whether the network card is 100M or 1000M in linux/centos

You can use the ethtool command to view it, using the format ethtool network interface name.

The following is an example. eth0 is the name of the network card. Use ifconfig to view the currently used network card.

Speed represents the network card bandwidth, Duplex represents the working mode, and Supported link modes represent the supported working modes.

(3) ETH full node height view extended reading:

Other uses of the ethtool command:

1. Query the network port location: ethtool -p ethX< /p>

This command is mostly used to manage server hosts with multiple network ports. Due to the large number of network ports on the backplane, sometimes we don’t know which physical port corresponds to eth0 or other device numbers, so we can use this command to query.

Usage: ethtool -p eth0

Effect: The two indicators of the physical port corresponding to the device number eth0 will flash

2. Modify the network port rate: ethtool -s

This command is mostly used to manually set the network rate. Generally, Gigabit network cards support three rates: 10|100|1000, and the unit is Mbps.

Usage: ethtool -s eth0 speed 1000 plex full autoneg off

Effect: Change the physical port corresponding to the device number eth0Set the rate to 1000Mbps, full-duplex working mode, and turn off auto-negotiation.

D. 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 through its dedicated cryptocurrency Ether (ETH). ) to handle peer-to-peer contracts.

Warm reminder:

E. What is the computing power of the entire ETH network today? How much

According to Spider Mining Pool data:
The computing power of the entire BTC network is 153.280EH/s, the mining difficulty is 21.72T, the current block height is 672055, and the theoretical income is 0.00000690/T/day.
The computing power of the entire ETH network is 418.403TH/s, the mining difficulty is 5380.94T, the current block height is 11923460, and the theoretical income is 0.00709464/100MH/day.
BSV’s entire network computing power is 0.544EH/s, the mining difficulty is 0.08T, the current block height is 675889, and the theoretical income is 0.0081/T/day.
The computing power of the entire BCH network is 1.596EH/s, the mining difficulty is 0.20, the current block height is 676209, and the theoretical income is 0.00056395/T/day.

F. ETH local node mining under WINDOWS

ETH mining mainly uses graphics cards to mine. Therefore, you need a PC with the following equipment:
Graphics card, motherboard, power supply, CPU, memory, hard drive (60G or above SSD recommended), extension cable, adapter cable, etc.
The graphics card determines the speed of mining, and the motherboard and power supply determine the stability of the mining machine to a large extent.

G. What is ETC/Ethereum Classic

A brief history of Ethereum Classic (ETC)

Ethereum Classic began with an unfortunate event.

In May 2016, the Decentralized Autonomous Organization (DAO) held a token sale with the goal of establishing a blockchain-based venture to fund future decentralization within the Ethereum ecosystem Applications (DApps).

Basically, a DAO is a complex smart contract that operates in a decentralized manner – computer code that automatically executes tasks between multiple parties when conditions are met.

Despite its ambitious goals and successful token sale, the DAO's code contained a major vulnerability that allowed attackers to steal ETH from decentralized organizations.

An attacker exploited this vulnerability to trigger the infamous DAO hacking incident in June 2016, maliciously stealing approximately $50 million worth of ETH.

There is no doubt that the DAO hacking incident shocked the Ethereum community and caused the price of ETH to fall from US$20 to US$13.

After the DAO hack, the Ethereum community had to choose from three options.

Do nothing and suffer the consequences of the attack; or

Initiate a soft fork and recover funds; or

Deploy a hard fork to Recover lost ETH.

Both soft forks and hard forks are major network upgrades. However, a soft fork allows non-upgraded users and upgraded users to communicate with each other, while a hard fork is not backwards compatible with previous versions.

As developers realized that deploying a soft fork would expose the network to distributed denial of service (DDoS) attacks, the Ethereum community decided to launch a hard fork to recover funds lost in the DAO hack.

Although this plan is supported by the majority of people, a small group of people in the Ethereum community are opposed. They believe that "code is law" and the blockchain network should be immutable. .

The failure of both parties to agree on a solution eventually led to the split of the Ethereum blockchain.

Those trying to recover their lost ETH opted for a hard fork, turning me onThe Ethereum (ETH) blockchain we know today, while another group stayed on the original Ethereum Classic (ETC) chain.

What problems does Ethereum Classic solve?

Ethereum Classic (ETC) is a blockchain platform that allows developers to deploy smart contracts and DApps.

While this functionality is identical to that of Ethereum (ETH), there are two main differences with the ETC blockchain.

First of all, the Ethereum Classic community opposes tampering with distributed ledgers and supports the view that "blockchain networks cannot and should not be modified."

Secondly, although there is no hard upper limit on the total supply of ETH, Ethereum Classic adopts a constant supply monetary policy, allowing the creation of up to 230 million ETC.

As a plus, Ethereum Classic launched the Atlantis hard fork last year to increase interactivity with Ethereum and improve the privacy protection of transactions through zk-SNARKS.

Recommended trading platforms for Ethereum Classic ETC

H. How to quickly identify the corresponding relationship between the network card ID and the physical network card (i.e. eth

How to quickly identify the corresponding relationship between the network card ID and the physical network card

I forgot to mark it when I moved it from a computer room. At this time, I still want to modify eth0 as the communication port. But it was troublesome to plug and unplug them one by one, so I wondered if there was a good way. After all, Linux is not as intuitive as Windows. You can see it by opening the network connection. At this time, a command like ethtool will be used. The command is explained in detail as follows:

-e displays EEPROM mp information, some network card drivers do not support this option
-E modifies the network card EEPROM byte
-k displays the status of the network card Offload parameter: on or off, including rx-checksumming, tx-checksumming wait.
-K modifies the status of the network card Offload parameter
-p is used to distinguish the physical location of the network card corresponding to different ethX. A common method is to make the LED on the network card port flash continuously; N indicates the continuous flashing of the network card. Time, in seconds.
-r If the status of the auto-negotiation module is on, restarts auto-negotiation
-S displays NIC- and driver-specific statistical parameters, such as the number of bytes received/sent by the network card, received/ The number of broadcast packets sent, etc.
-t Let the network card perform self-test, there are two modes: offline or online
-s Modify some configurations of the network card, including network card speed, simplex/full-duplex mode, mac address, etc.

I. All the virtual currency ETH has been bought, so how much room for growth is there

The following aspects determine the price of virtual currencies such as ETH: 1. Frequency of use, 2. Actual use, 3. The number of people participating in buying and selling.

As for how much room there is for growth, the current price of Ethereum is around 6,600. Some time ago, due to the frequent private placements using Ethereum, Ethereum rose to more than 10,000. Ethereum is a smart contract and is developed based on Ethereum. There are countless tokens in Ethereum, so its prospects as the underlying public chain of smart contracts change with the popularity of blockchain. However, it is precisely because of the shortcomings of Ethereum that the main chain was exposed some time ago. Congestion, excessive handling fees, etc., development is close to the bottleneck, so its upside lies in whether developers can improve the main chain environment according to the shortcomings. As for the number of participants, it is not a big problem now. Pay more attention to the current development progress of developers and focus on If you are good at doing things, your future is boundless.

The websites that can currently trade Ethereum are: BtcTrade International Station, Huobi, Binance, etc.
