Le Guide Complet De La Blockchain Ethereum En 2022

Blockchain est actuellement  l' un des mots-clés les plus recherchés  par Google  , et beaucoup d'entre vous ont déjà entendu parler de Bitcoin ou d' Ethereum. Toutes ces crypto-monnaies sont basées sur cette technologie appelée  Blockchain.

Qu'est-ce que la blockchain

La blockchain  est l'une des meilleures inventions technologiques du 21ème siècle. Le cerveau derrière la Blockchain  est une personne ou un groupe de personnes connu sous le pseudonyme de  Satoshi NakamotoLa blockchain  permet à l'information numérique d'être distribuée mais pas copiée et décentralisée. En conséquence, la technologie blockchain a créé un nouveau type d'Internet.

Tutoriel sur la blockchain Ethereum

Nous utiliserons  Ethereum Blockchain  pour démarrer notre programmation et comprendre les différentes bibliothèques qui l'entourent. Dans ce didacticiel, nous voyons le langage que nous utiliserons pour commencer le développement dans la Blockchain Ethereum et comment nous pouvons créer un serveur et récupérer les données dans la page Web. Après cela, nous approfondirons les tutoriels suivants. Ce n'est qu'un aperçu de base d' Ethereum .

Étape 1 : Installez les packages.

Tout d'abord, nous allons créer un dossier de projet, et dans celui-ci, nous allons créer un  fichier package.json  en tapant la commande suivante. Ensuite, vous devez avoir Node.js  installé sur votre machine.

 

npm init

Il créera un  fichier package.json  . Installez maintenant le package suivant.

npm install --save-dev nodemon

Lorsque nous enregistrons le fichier serveur Node.js, il redémarre automatiquement le serveur, nous n'avons donc pas besoin de redémarrer le serveur manuellement.

 

Maintenant, nous allons installer le  framework web express node.js  en tapant la commande suivante.

npm install --save express

OK, créez un dossier appelé public  dans le répertoire racine, et dans ce dossier, créez un fichier HTML  appelé  index.html.

Notre  fichier package.json  ressemble à ceci.

{
  "name": "ethereum-blockchain",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "nodemon server"
  },
  "author": "KRUNAL LATHIYA",
  "license": "ISC",
  "devDependencies": {
    "nodemon": "^1.14.11"
  },
  "dependencies": {
    "express": "^4.16.2"
  }
}

Maintenant, créez un  fichier server.js  dans le dossier racine et écrivez le  code du serveur node.js. 

// server.js

const express = require('express');
let app = express();
const PORT = 3000;

app.get('/', function(req, res){
   res.sendFile(__dirname + '/public/index.html');
});

app.listen(PORT, function(){
   console.log('Server is started on port:',PORT);
});

Étape 2 : modifiez le fichier index.html.

Nous devons faire une  requête ajax  au  serveur nodej.js  pour afficher les données sur la page Web. Pour envoyer la requête  ajax  , nous pouvons utiliser jQuery, axios ou  fetch  library. Mais pour le moment, nous allons utiliser  du javascript simple  pour créer et envoyer la  requête AJAX.

<!DOCTYPE html>
<html lang="en">
<head>
   <meta charset="UTF-8">
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <meta http-equiv="X-UA-Compatible" content="ie=edge">
   <title>Ethereum Blockchain Tutorial</title>
</head>
<body>
   <p id="blockchain">Ethereum tutorial</p>
   <button onclick="EthereumServer()">Connect to the Ethereum</button>
</body>
<script>
   function EthereumServer()
   {
      alert('blockchain');
   }
</script>
</html>

Ici, je viens de tester la  fonction onclick  , et maintenant dans cette fonction, nous devons envoyer une requête ajax à un serveur node.js.

<!DOCTYPE html>
<html lang="en">
<head>
   <meta charset="UTF-8">
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <meta http-equiv="X-UA-Compatible" content="ie=edge">
   <title>Ethereum Blockchain Tutorial</title>
</head>
<body>
   <p id="blockchain">Ethereum tutorial</p>
   <button onclick="EthereumServer()">Connect to the Ethereum</button>
</body>
<script>
   function EthereumServer()
   {
      var xhttp = new XMLHttpRequest();
      xhttp.onreadystatechange = function() {
         if (this.readyState == 4 && this.status == 200) {
         document.getElementById("blockchain").innerHTML = this.responseText;
         }
      };
      xhttp.open("GET", "/blockchain", true);
      xhttp.send();
   }
</script>
</html>

Dans le  fichier server.js  .

// server.js

const express = require('express');
let app = express();
const PORT = 3000;

app.get('/', function(req, res){
   res.sendFile(__dirname + '/public/index.html');
});

app.get('/blockchain', function(req,res){
   res.json('ethereum request got it');
})

app.listen(PORT, function(){
   console.log('Server is started on port:',PORT);
});

Étape 3 : Installez la pile blockchain.

Nous avons besoin de deux choses.

  1. réseau testrpc
  2. web3

We need to install testrpc globally in our system. It will work as a virtual blockchain network in our memory. We can play around with this, and when we get ready for production, we will use the actual ethereum blockchain to develop decentralized apps. (DApps)

We need to install testrpc globally, so type the following command in your terminal.

npm install -g ethereumjs-testrpc

After installing the package, you can now see how it looks like by typing the following command.

testrpc

 

chaîne de blocs Ethereum

You can see here; it has its network and some test accounts to work with. We will fetch the accounts and display them on the front end. So first, we need to communicate the testrpc network with our node.js application.

Step 4: Install web3.js

Nous devons installer la version 1.0.0 du  web3. Tapez donc la commande suivante dans votre terminal.

npm install web3

Maintenant, incluez ceci dans notre  fichier server.js  .

// server.js

const express = require('express');
let app = express();
const PORT = 3000;

const Web3 = require('web3');
let web3 = new Web3();


app.get('/', function(req, res){
   res.sendFile(__dirname + '/public/index.html');
});

app.get('/blockchain', function(req,res){
   res.json('ethereum request got it');
});

app.listen(PORT, function(){
   console.log('Server is started on port:',PORT);
});

Nous pouvons appeler des méthodes de fournisseurs sur la classe  web3  comme suit.

Si nous voulons savoir quels fournisseurs ont l'habitude de communiquer avec le testrpc, alors console.log  les fournisseurs.

console.log(Web3.providers);

Cela nous donnera trois types de fournisseurs.

  1. CIB
  2. HTTP
  3. WebSocket

Nous utiliserons le fournisseur HTTP puisque testrpc l'utilise et s'exécutera sur le port :  8545

Nous pouvons donc récupérer les comptes de l'application testrpc à node.js.

//server.js

const Web3 = require('web3');
let web3 = new Web3();

web3.setProvider(new Web3.providers.HttpProvider('http://localhost:8545'));

web3.eth.getAccounts(function(err, res){
   console.log(err, res);
});

Il donnera un tableau de comptes. Le premier argument est une erreur. Dans ce cas, il est nul et le deuxième argument est un tableau de comptes.

Touches finales

Notre  fichier server.js  final ressemble à ceci. N'oubliez pas que nous devons faire fonctionner deux serveurs à la fois.

  1. testrpc
  2. node.js

Si l'un d'eux est arrêté, tout notre système plantera. Ainsi, les réseaux blockchain ne s'arrêteront jamais et fonctionneront indéfiniment en temps réel. Ainsi, dans ce réseau, des blocs seront ajoutés à l'avenir. Plus de blocs sont ajoutés, et plus le réseau sera sécurisé.

// server.js

const express = require('express');
let app = express();
const PORT = 3000;

const Web3 = require('web3');
let web3 = new Web3();

web3.setProvider(new Web3.providers.HttpProvider('http://localhost:8545'));

app.get('/', function(req, res){
   res.sendFile(__dirname + '/public/index.html');
});

app.get('/blockchain', function(req,res){
   web3.eth.getAccounts(function(err, accounts){
      if(err == null) res.send(JSON.stringify(accounts));
   });
});

app.listen(PORT, function(){
   console.log('Server is started on port:',PORT);
});

Ainsi, enfin, dans le frontend, lorsque vous cliquez sur le bouton, le tableau des comptes s'affiche. En effet, ces comptes se trouvent dans le réseau Ethereum et nous avons réussi à connecter notre application node.js au réseau Ethereum.

Blockchain Certification | Blockchain Training Course | Blockchain Council

In all the market sectors, Blockchain technology has contributed to the redesign. The improvements that were once impossible have been pushed forward. Blockchain is one of the leading innovations with the ability to influence the various sectors of the industry. It also has the ability to be one of the career-influencing innovations at the same time. We have seen an increasing inclination towards the certification of the Blockchain in recent years, and there are obvious reasons behind it. Blockchain has everything to offer, from good packages to its universal application and futuristic development. Let’s address the reasons why one should go for Blockchain certification.

5 advantages of certification by Blockchain:

1. Lucrative packages- Everyone who completes their education or upskills themselves wants to end up with a good bundle, not only is one assured of a good learning experience with Blockchain, but the packages are drool-worthy at the same time. A Blockchain developer’s average salary varies between $150,000 and $175,000 per annum. Comparatively, a software developer gets a $137,000 per year salary. For a Blockchain developer, the San Francisco Bay area provides the highest bundle, amounting to $162,288 per annum. There’s no point arguing that learning about Blockchain is a smart decision with such lucrative packages.

2. Growing industry- When you select any qualification course, it becomes important that you choose a growing segment or industry that promises potential in the future. You should anticipate all of these with Blockchain. The size of the blockchain market is expected to rise from USD 3.0 billion in 2020 to USD 39.7 billion by 2025. This will see an incredible 67.3 percent CAGR between 2020-2025. To help business processes, several businesses are outsourcing Blockchain technologies. This clearly demonstrates that there will be higher demand in the future for Blockchain developers and certified Blockchain professionals.

3. Universal application- One of the major reasons for the success of Blockchain is that it has a global application. It is not sector-specific. Blockchain usage cases are discovered by almost all market segments. In addition, other innovations such as AI, big data, data science and much more are also supported by Blockchain. It becomes easier to get into a suitable industry once you know about Blockchain.

**4. Work protection-**Surely you would like to invest in an ability that ensures job security. You had the same chance for Blockchain. Since this is the technology of the future, understanding that Blockchain can keep up with futuristic developments will help in a successful and safe job.

**5.**After a certain point of your professional life, you are expected to learn about new abilities that can help enhance your skills. Upskilling is paramount. Upskilling oneself has become the need for the hour, and choosing a path that holds a lot of potential for the future is the best way to do this. For all computer geeks and others who want to gain awareness of emerging technology, Blockchain is a good option.

Concluding thoughts- opting for Blockchain certification is a successful career move with all these advantages. You will be able to find yourself in a safe and secured work profile once you have all the knowledge and information. Link for Blockchain certification programme with the Blockchain Council.

A Quick Guide: Ethereum VS Ethereum Classic

Ethereum Classic (CRYPTO: ETH) and Ethereum (CRYPTO: ETH) are two cryptocurrencies that use the Ethereum blockchain (CRYPTO: ETC).

But why do two cryptocurrencies have the same name?

Yes, something significant occurred. There was a time when the Ethereum ecosystem was all-encompassing. Following one of the most high-profile events in cryptocurrency history, a hard fork occurred, resulting in two competing blockchain network implementations.

Ethereum Classic is an older Ethereum version that implemented smart contracts using a Proof-Of-Work platform. Following a blockchain hack, Ethereum focused on the code that converts smart contract execution from Proof-of-Work to Proof-of-Stake in order to protect against future attacks.

Are you interested in learning more about Ethereum programming? The easiest way to get started is to take Ethereum certification courses.

The Differences Between Ethereum and Ethereum Classic

Ideological
The immutability of blockchains is something Ethereum does not believe in. Supporters of this perspective argue that people should not be allowed to change the blockchain on their own whims; otherwise, the blockchain would be susceptible to human corruption.

Ethereum’s creators built the platform with this in mind. This is Ethereum Classic’s basis, and the ecosystem’s creators agree.

According to ETH supporters, the Hard Fork was needed in order to be fair. It refunded those who had lost their Ether and devalued the tokens stolen by the hacker.

Value
The value of ETC has risen to 15 times that of ETH. One of the key reasons for this is that ETH is backed by a number of powerful members of the crypto community and is continually updated.

Although ETC has a low market capitalization, it has recently gained the support of a number of powerful individuals.

Potential
It’s debatable if ETC will succeed. Some argue that ETC has no future and that the majority of its members are scammers, while others believe it has a bright future. We don’t know if ETC would extend.

On the other hand, several experts assume that after Bitcoin, ETH would be the first cryptocurrency to hit $10,000. This is a tremendous achievement that reflects ETH’s immense ability. It’s now increasingly growing, with regular updates.

Characteristics
This is another area where the distinction between ETH and ETC is too clear. ETH has received support from the Enterprise Ethereum Alliance (EEA), a group of over 200 businesses working to incorporate blockchain for smart contracts in Fortune 500 companies.

The EEA includes companies such as JP Morgan, ING, Microsoft, and Toyota, to name a few. Every day, ETH receives many updates, helping it to stay on top of the industry and its demands.

The bulk of ETH’s alerts, on the other hand, are inaccessible to ETC. As a consequence, in terms of functionality and quality, it falls far behind.

Wrapping up
In other words, there will never be an agreement on which of these two is superior. On the one side, there’s the immutability theory, and on the other, there’s the theory of continuous growth. When you learn more about blockchain and its concepts, you’ll see how complicated this subject is.

Careers in ethereum development are on the rise, and blockchain has forever transformed the face of the technology sector. Start the journey to become an ethereum blockchain developer with the Blockchain Council!

Swarm, IPFS and BigchainDB: Comparing Data Storage and Decentralization

Data and content management are two of the main capabilities in many of the real-world business applications, such as information portals, Wikipedia, and ecommerce and social media applications.

There is no exception in the decentralized world. During the EVM discussion, we briefly looked at the EVM capability for storing data on Ethereum.

Although it is convenient, it is not generally intended to be used for data storage. It is very expensive too. There are a few options application developers can leverage to manage and access decentralized data and contents for decentralized applications, including Swarm (the Ethereum blockchain solution), IPFS and BigchainDB (a big data platform for blockchain). We will cover them in the rest of this section.

Swarm

Swarm provides a content distribution service for Ethereum and DApps. Here are some features of Swarm:

·    It is a decentralized storage platform, a native base layer service of the Ethereum web 3 stack.

·    It intends to be a decentralized store of Ethereum’s public record as an alternative to an Ethereum on-chain storage solution.

·    It allows DApps to store and distribute code, data, and contents, without jamming all the information on the blockchain.

Imagine you are developing a blockchain-based medical record system, you want to keep track when the medical records are added, where the medical records are recorded, and who has accessed the medical records and for what purpose. All these are the immutable transaction records you want to maintain in the blockchain. But, the medical records themselves, including physician notes, medical diagnosis, and imaging, and so on, may not be suitable to be stored in the Ethereum blockchain. Swarm or IPFS are best suited for such use cases.
