What are Smart Contracts?

A smart contract is code on the blockchain that runs automatically when conditions are met—like a trustless program no one can tamper with.

no backend, no database.

It’s like an open API that runs forever.

Smart contracts = the building blocks of Web3.

This is what Web3 is about: code as trust.

No banks. No middlemen. Just logic on-chain.

What is Layer 2?

Layer 2 is built on top of Layer 1 to make blockchains faster and cheaper. It processes transactions off-chain, then settles them on the main chain.

Examples:

•Polygon – Scales Ethereum

•Optimism – Faster Ethereum smart contracts

•Lightning Network – Instant Bitcoin payments

What is Layer 1 Blockchain?

Layer 1 is the core blockchain network where transactions happen and get finalized. It runs its own rules (consensus mechanism) and hosts smart contracts and dApps directly on-chain.

Examples:
Bitcoin (BTC) – Digital money on a secure, decentralized network.

Ethereum (ETH) – Smart contract pioneer.

Solana (SOL) – Fast and scalable Layer 1.
Avalanche (AVAX) – Eco-friendly and high-speed chain.

Types of Blockchains: Layer 1 vs Layer 2.

In the fast-evolving world of blockchain, not all chains are created equal. Some serve as the foundation of an ecosystem, while others are built on top to enhance performance. This brings us to two crucial terms: Layer 1 and Layer 2 blockchains.

How to Get Started as a Blockchain Developer in 2025

Blockchain is reshaping industries beyond crypto — finance, health, governance, and more. If you want to become a Blockchain developer in 2025, here’s a clear roadmap to guide your journey.

1: Learn the Fundamentals
Understand what blockchain is: blocks, chains, hashing, immutability, consensus.

Learn the difference between public, private, and consortium blockchains.

Explore core concepts like wallets, gas, nodes, and smart contracts.

Conclusion: Which Should You Build On?

Choose Solana if:

You need high throughput and low fees.

Your app is speed-critical (e.g., games, real-time platforms).

You’re comfortable with Rust or want to explore new territory.

Choose Ethereum if:

You want wide adoption and community support.

You’re building DeFi or need robust composability.

You prefer using Solidity and a mature dev ecosystem.

Solana vs Ethereum: Which One Should You Build On?...

2. Fees🤔

Ethereum: High and volatile gas fees (especially during congestion)

Solana: Average transaction fee is ~$0.00025
Low-cost dApps (NFTs, microtransactions, DeFi) thrive on Solana.
