Welcome to Module 2-Course 2 of Mission Web3!

In this module, we will provide you with a comprehensive understanding of on-chain transactions, gas fees, and common web3 slang.

What is an On-Chain Transaction?

An on-chain transaction refers to a transaction that is recorded and validated on the blockchain network.

It is important to note that any and all transaction needs to be processed and confirmed by the blockchain network, which involves being added to a block and included in the blockchain's ledger.

This ensures the transparency and security of your transaction, as it is recorded on a decentralized network.

What Are Gas Fees?

Gas fees are the costs associated with performing transactions or executing smart contracts on a blockchain network.

In simpler terms, when you want to do something on the blockchain, like sending cryptocurrency or interacting with a decentralized application (DApp), you need to pay a small amount of cryptocurrency as a fee for that action to be processed by the network.

This fee is called a gas fee.

The more complex or demanding your transaction is, the more Gas it needs to complete. So, if you want your transaction to happen quickly, you might need to pay a higher Gas fee to give it a little boost.

Gas Fees Are Important Because:

  • Resource Allocation: They prevent the network from being overwhelmed by resource-intensive operations, ensuring fair access for everyone.

  • Security: By requiring a cost for each action, it prevents spam and malicious attacks on the network.

  • Incentives: Miners or validators who process transactions and smart contracts are rewarded with these gas fees, incentivizing them to participate in the network's maintenance.

It's worth noting that gas fees can vary widely based on network congestion.

During busy times, when many people are using the blockchain, gas fees can rise significantly.

This has led to discussions around scalability and the development of solutions to reduce gas costs.

Web3 Slang

In the web3 space, there is a unique vocabulary and set of terminologies, often referred to as "slang," that are commonly used.
