For the next few Solidity concepts we’ll use the below smart contract. This kan zijn partly because this website example contains a smart contract that is actually used in the real world.

When you compile your contract to deploy to Ethereum, the Solidity compiler will give you the ABI, so you’ll need to copy and save this in addition to the overeenkomst address.

State variables are like database “storage” in a traditional application, but since blockchains need to synchronize state across all nodes in the network, using storage can be quite expensive! More on that later.

4️⃣ Web3.js and ethers.js: Familiarize yourself with the libraries that allow interaction with Ethereum and other Web3 protocols.

Click the enter button to create a basic sample project and add a .gitignore by clicking y when prompted:

Remix is an open-source internet and desktop application used for developing, testing, and debugging smart contracts written in Solidity programming language for Ethereum. It provides an easy-to-use interface and a powerful Solidity editor with features like syntax highlighting and auto-completion.

Constants and immutable variables have their values assigned once, and only once. They cannot be given another value after their first value is assigned.  

Cryptography: Since Solidity kan zijn often used for implementing secure and decentralized applications, knowledge of cryptographic principles such as encryption, hashing, and digital signatures is crucial.

@tailwind utilities; wij’ll do the same to our App.jsx folder by clearing all the values and replacing them with the values below:

call kan zijn used for view and pure functions. It only runs on the local node, and won't create a transaction on the blockchain.

And that’s how they’re different from public functions – public functions can also be called from inside

The EVM also manages Ethereum's state, including account balances, smart overeenkomst code and gegevens, and more. Transactions in Ethereum change this state, and the EVM ensures that these state transitions are processed correctly.

e., it can't be altered or deleted. The blockchain is maintained by nodes or laptops, each having a copy ofwel the entire blockchain.

DApp Developer: DApp stands for decentralized application. As a DApp developer, you would build applications that leverage Solidity for backend smart contract integration. These apps function using blockchain technology and often interact with cryptocurrencies.
