A Blockchain is a constantly growing ledger that keeps a permanent record of all the transitions that have taken place in a secure and immutable way. It can be used for the secure transfer of money, assets, contracts, etc. A main key feature of blockchain technology is to secure all the records without requiring a third-party intermediary such as a bank or government.
Let’s breakdown the definition :
Ledger: It is a file that is constantly growing.
Permanent: It means once the transaction goes inside a blockchain, you can put up it permanently in the ledger.
Secure: Blockchain securely placed information. It uses very advanced cryptography to make sure that the information is locked inside the blockchain.
Chronological: Chronological means every transaction happens after the previous one.
Immutable: It means as you build all the transactions onto the blockchain, this ledger can never be changed.
Need of Blockchain
Blockchain technology has become popular because of the following:
Time reduction: Blockchain can allow the quicker settlement of trades. It does not take a lengthy process for verification, settlement, and clearance. It is because a single version of agreed-upon data is available between all stakeholders that why it takes less time.
Unchangeable Transactions: Blockchain registers transactions in a chronological order that certifies all operations in a proper way. When a new block is added to the ledgers, it cannot be removed or modified it’s immutable.
Reliability: Blockchain certifies and verifies the identities of each interested party. This removes double records, reducing rates, and accelerates transactions.
Security: Blockchain uses advanced cryptography to make sure that the information is locked inside the blockchain. It uses distributed Ledger technology where each party holds a copy of the original chain, so the system remains operative, even a large number of other nodes fall.
Collaboration: It allows each party to transact directly with each other without requiring a third-party intermediary like a bank or government.
Decentralized: It is Decentralized because there is no central authority supervising anything. There are standards rules on how every node exchanges blockchain information. This method ensures that all transactions are validated or secure, and all valid transactions are added one by one.
Let’s understand the Blockchain Developers
There are two types of blockchain developers:
1. Core blockchain developers
These developers are mainly responsible for building Decentralized Applications (DApp) Back-end (main engine) (Dapps). Examples include Ethereum, Bitcoin, and Cardano Blockchains.
2. Blockchain software developers
These Blockchain developers are mainly responsible for designing and building the front-end of Dapps. The web and mobile interfaces that users interact with. Most blockchain developers fall under this category.
Blockchain Development Platform
- Hyperledhet: An umbrella project of open-source blockchain to build an industry-grade blockchain app
- Etherum: A decentralized public platform that runs decentralized apps or dApps
- Stellar: It is an open platform for building a financial product that connects people.
- EOS: EOS is a decentralized blockchain, which can process fast free transitions.
- Corda: It is an open-source blockchain platform for businesses.
Libraries and frameworks for blockchain development
1. Web3.js: It’s a collection of libraries that allows you to interact with the Ethereum node either remotely or locally using HTTP, Websocket, or IPC.
2. React.js: It’s a javascript library that enables programmers to build beautiful user interfaces. You can use any other framework as well.
3. Ethers.js: It is a collection of libraries that allows you to interact with the Ethereum blockchain and its ecosystem.
4. Metamask: It is a Cryptocurrency wallet and a browser extension that allows a user to buy, store, and swap tokens on the Ethereum blockchain or any other blockchain.
5. Node.js: JavaScript runtime environment that executes javascript code outside a web browser. Decentralized applications(DApp) usually use node.js to interact with smart contracts and public nodes.
6. Ganache: This library is used for Ethereum blockchain development. It enables developers to develop, deploy, and test decentralized applications(DApps) in a safe and deterministic environment without interacting with the main Ethereum blockchain.
Which programming languages are best for blockchain?
- Solidity: This programming language is used for creating Ethereum smart contracts.
- 2. Javascript: This is used primarily for creating user interfaces.
- Go and C++: These languages are used by the blockchain core developers to build the back-ends of blockchain systems.
- Haskell: This programming language is used by core blockchain developers in building the Cardano blockchain.
What are blockchain apps or DApps?
DApps are decentralized applications. A Blockchain has no server that plays the role of an intermediary between users that exchange messages, money, or data. This opens lots of possibilities for many companies that’s why Blockchain application development is relevant for so many businesses.
What are the Benefits of Blockchain apps?
Easy Transactions: These apps takes only five minutes to set up a blockchain wallet and allow users to buy things with the cryptocurrency without any charges
Great cryptocurrency exchange experience: Buy and sell cryptocurrencies in a more convenient way via a mobile app
High Security: All the data is decentralized and each member of the network has a copy of all chains so it is fully secure with the hackers.
Key Industries for DApps:
- Games Industry
- Exchanges
- Wallets
- Finance services
- Healthcare
- Music industry
- Real estate
