Ⅰ Hard forks in the blockchain, what does Ethereum Classic ETC mean

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 capital 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 among multiple parties when conditions are met.

Despite its ambitious goals and successful token sale, the DAO’s code has a major vulnerability that allows attackers to steal ETH from the decentralized organization.

The attacker exploited this vulnerability in June 2016, leading to the infamous DAO hack, which maliciously stole approximately $50 million worth of ETH.

There is no doubt that the DAO hack shocked the Ethereum community and caused the price of ETH to drop from $20 to $13.

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

• Do nothing and try to bear the consequences of the attack;

• Start a soft fork and recover funds;

• p>

• Deploy a hard fork to recover lost ETH.

Soft forks and hard forks are both major network upgrades. However, soft forks allow non-upgraded users and upgraded users to communicate with each other, while hard forks are not backward compatible with previous versions.

As developers realized that deploying a soft fork would expose the network to a Distributed Denial of Service (DDoS) attack, the Ethereum community decided to initiate a hard fork to recover funds lost in the DAO hack.

While this proposal is supported by the majority, a small minority in the Ethereum community is opposed, arguing that “code is law” and that blockchain networks should be immutable .

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

Those who were trying to get back their lost ETH opted for a hard fork that opened the Ethereum (ETH) blockchain as we know it today, while another group stayed behind in the original Ethereum Classic ( ETC) on the 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), the ETC blockchain has two main differences.

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, while there is no hard cap on the total supply of ETH, Ethereum Classic adopts a constant supply monetary policy that allows a maximum of 230 million ETC to be created.

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

The recommended trading platform for Ethereum Classic ETC: Huobi, OKEX, AAX, etc.

Ⅲ What is the difference between Gikee, a blockchain data monitoring tool, and searchain?

In fact, gikee and searchain are both tools for monitoring data on the chain, and they both check ETH and ERC20 . However, there are still many differences between the two. The biggest difference is that gikee is the world’s first APP, and seachain is the PC side. In addition, as an APP, gikee has a change reminder, and can receive information reminders on the chain in real time. Therefore, I personally think that gikee is relatively more convenient.

IV What is the Ethereum of the platform project in the blockchain

Ethereum, Ethereum, ETH for short. At the end of 2013, Vitalik released the Ethereum white paper, and in July 2014, the pre-sale of Ethereum began. At that time, people in the circle called this kind of token issuance “coin crowdfunding”. Through the 42-day pre-sale, the Ethereum team raised more than 30,000 bitcoins through the pre-sale of 60,102,216 ethers; in addition, the early contributors who participated in the development before the pre-sale and the developers who have been engaged in the project research for a long time are respectively based on ether9.9% of the total coin offering will be allocated. So when Ethereum was officially released, there were more than 72 million ETH. After the Ethereum pre-sale is over, the proof-of-work mechanism PoW is used for mining, and the miners are rewarded every year according to 26% of the total issuance at that time. In October 2014, Ethereum reduced the block production time from 60 seconds to 12 seconds, and it is currently stable at 15 seconds, and each block rewards 5 ETH.
Although the PoW mining mechanism is adopted, the block generation mechanism of Ethereum is still different from that of Bitcoin. Due to the short block time of Ethereum, it is easy to form orphan blocks in Ethereum, which refers to blocks that are not on the longest chain. Bitcoin’s orphan blocks do not have any block rewards, but in Ethereum, orphan blocks can be referenced, and the referenced orphan blocks are called “uncle blocks”, and the data they package is also recorded in the block. in the chain. Unlike Bitcoin, Ethereum’s uncle blocks are rewarded, and each uncle block can be rewarded with a maximum of 4.375 ETH.
Ethereum is a programmable, Turing-complete blockchain development platform, equivalent to a decentralized global computer. On a programming system, there are usually some compiled and executed virtual machines to support. JAVA has JVM, and in Ethereum, there is also the virtual machine EVM of Ethereum, which can execute arbitrarily complex algorithm code. Developers can use existing programming languages ​​such as JavaScript or Python to create their desired applications on Ethereum. Through the virtual machine of Ethereum, you can easily issue digital assets, write smart contracts, build and run decentralized applications, and establish decentralized autonomous organizations.
Ether (ETH) is also known as the fuel within Ethereum. Unlike currency digital assets, Ethereum is used to pay for smart contracts in addition to transfers.
In order to avoid rubbish contracts and rubbish applications on the Ethereum blockchain, to build and run smart contracts on Ethereum, you must pay for smart contracts in ETH. For example, to transfer your newly created digital assets on the Ethereum blockchain, you need to pay the handling fee in ETH, not your newly created digital assets.

Ⅳ What is Ethereum and what is the relationship between Ethereum and blockchain

What is Ethereum:

Ethereum is a technology based on Bitcoin and concepts applied to computer innovation. Ethereum itself copied many of Bitcoin’s technology to maintain the computer platform. Blockchain technology is one of them.
The Ethereum platform can safely run any program the user wants.

Advantages of Ethereum over other altcoins

Before the emergence of Ethereum, there were already some digital currencies imitating Bitcoin. However, these projects themselves have certain shortcomings, and can only support one or several specific applications at the same time. (A better digital currency trading platform is in “Bihui”)

However, the reason why Ethereum can surpass the limitations of these previous projects is because of the core idea of ​​Ethereum.

What Ethereum wants to implement is a blockchain protocol with a built-in programming language. Since the programming language is supported, theoretically any blockchain application can be defined in this language, and then used as a An application that runs on top of the Ethereum blockchain protocol.

Ethereum is designed to be flexible and adaptable.

Ethereum aims to set the strengths of blockchain technology, in order to add the advantages of blockchain, such as decentralization, openness and security, to almost all computing fields .

Blockchain applications of Ethereum

Ethereum has many blockchain applications, such as digital applications of gold and stocks, financial derivatives applications, DNS and digital applications certification, etc.

Ethereum has more than 100 blockchain applications implemented by many startups.

Ethereum is also closely watched by some financial institutions, banking consortia (such as R3), and large companies like Samsung, Deloitte, RWE, and IBM, which has also spawned a number of initiatives such as simplifying And blockchain applications such as automated financial transactions, merchant loyalty index tracking, gift cards designed to decentralize electronic transactions, and more.

The relationship between Ethereum and blockchain:

Ethereum is a programmable blockchain.

Instead of giving users a set of pre-defined actions (such as bitcoin transactions), Ethereum allows users to create complex actions at their own will.

In this way, Ethereum can be used as a platform for many types of decentralized blockchain applications, including but not limited to cryptocurrencies.

Like other blockchains, Ethereum has a peer-to-peer network protocol. The Ethereum blockchain database is maintained and updated by numerous nodes connected to the network. Each network node runs an Ethereum simulator and executes the same instructions. Therefore, people sometimes refer to Ethereum figuratively as”World Computer”.

Ⅵ Who knows what is the copyright principle of authenticating videos and pictures on the blockchain

Basically the principle is the same, take Baopin.com as an example, Baopin.com video block Chain authentication is actually a DApp. It first takes a screenshot of the key frame per minute of the video, then transcodes it into a string of unique numbers, and uploads it to the Ethereum blockchain.

VII What are the current problems of the Ethereum blockchain ETH

There are three major problems that the Ethereum blockchain currently exposes, and its founder Vitalik Buterin has been unable to interpret it for a long time. The first is the overall low performance and TPS of the Ethereum blockchain; the second is that the resources are not isolated. The incident of the CryptoKitties virtual cat once occupied 20% of the traffic of the entire Ethereum, which directly caused the users of the Ethereum network to be unable to develop timely. Transactions are the biggest pain point of non-isolation of resources; the third problem lies in the manifestation of Ethereum’s governance structure. Blockchain is a decentralized distributed ledger. Since Ethereum’s past, the founder team has dominated its network development, which is too central. The ETH, ETC, ETF and other forks have appeared in the current Ethereum, and the Ethereum community is currently in a divided governance state. In the eyes of Ma Haobo, founder and CEO of “aelf”, the various ills that are currently occurring in the Ethereum network are unacceptable. Therefore, the positioning of “aelf” was born to target the next-generation decentralized underlying computing platform of Ethereum, focusing on solving the current problems of insufficient performance, non-isolation of resources, and governance structure in Ethereum.

VIII What should I do if I want to invest in the blockchain Bitcoin Ethereum

If you want to invest, it is recommended to consider whether you are optimistic about this industry, because digital currencies such as Bitcoin , in fact, it has no real value, only collection value, all the speculation prices are relatively high, if you plan to invest, you must first choose a reliable old platform with a good reputation, so that at least money will not disappear out of thin air, you can see The two companies, AEX and Huobi, have been in business for more than 6 years, and their reputation has been good. For long-term investment, you can go to AEX for currency management

Ⅸ What is Ethereum and what is the relationship between Ethereum and blockchain

Ⅸ h2>

Ethereum is also a product of Blockchain 2.0, which is an open and complete solution for smart contracts. Bitcoin is the most important application of blockchain 1.0, and it completes currency and payment transactions well. But when we need to record and transfer more complex asset types, we need the third step – a more powerful scripting system – to eventually become Turing complete (capable of running any currency, protocol and blockchain). Ethereum is a blockchain-based project that aims to provide a Turing-complete scripting language and a Turing-complete platform.

Blockchain 1.0 mainly refers to Bitcoin, Blockchain 2.0 extends to all assets, while Blockchain 3.0 goes beyond currency, beyond the financial field, and even beyond the commercial field, extending to In all fields, it penetrates into all aspects of our lives, including politics, social interaction, education, medical care, etc. According to the predictions and ideas of people in the industry, the blockchain 3.0 era will be realized in the next five years. At that time, the blockchain will become as recognized and accepted by all the public as the Internet, thus completely subverting our lives.

McKinsey & Company submitted a blockchain technology report to the U.S. Federal Insurance Advisory Committee, which called 2009 to 2016 the “Dark Ages”, arguing that all blockchain solutions during this period Based on Bitcoin, the new era of blockchain will begin in 2016. By then, the application of blockchain will become unprecedentedly widespread. To apply a quote from the McKinsey report: Based on the current speed of blockchain development, we believe that blockchain solutions may realize their full potential in the next 5 years.
