How does Solana work?

At its core, Solana is a network of computers (also called nodes) that work together to process transactions. Here's how it works:

Step 1: Transaction Initiation- You initiate an action, like sending SOL or interacting with a dApp (decentralised application), from your wallet.

Step 2: Validation by Validators- Your transaction is sent to Solana’s validators, which are independent computers that verify and confirm that the transaction is legitimate.

Step 3: Consensus and Confirmation- Validators reach consensus in less than a second, confirming your transaction and adding it to the blockchain.

Step 4: Instant Confirmation- Once confirmed, the transaction is immediately recorded on the blockchain, and the recipient sees the result in real-time.

This entire process takes mere seconds, allowing for near-instantaneous confirmation of transactions.

How to create your first wallet?

Setting up your Solana wallet is a simple four-step process:

Understanding Solana Transaction Fees

Transaction fees are a vital part of any blockchain network, and Solana has designed its fee structure to be both affordable and predictable. These fees are used to compensate validators, prevent network abuse, and prioritise transactions during high traffic periods. What sets Solana apart is its remarkably low transaction costs, which make it an attractive platform for both developers and users.

Solana’s Fee Structure
Solana has three main types of fees:

1. Base Fee: Every transaction on the Solana network pays a small base fee. This fee is set at 0.000005 SOL (5,000 lamports), which typically costs less than $0.0005 per transaction. This low cost ensures that even frequent or small transactions are viable.
2. Priority Fee: During busy times, users can opt to add a small priority fee to speed up their transactions. Even in high-demand periods, priority fees remain low, typically under $0.01. This ensures that users can still get their transactions processed quickly without paying excessive amounts.
3. Storage Rent: For creating new accounts, such as token accounts, Solana requires a small deposit (~0.002 SOL). This rent is refundable when the account is closed, preventing network spam and helping with efficient storage management.

Typical costs for different activities

Here are some common Solana transaction costs:

• Sending SOL or tokens: $0.0005
• Swapping tokens: $0.0005
• Buying an NFT: $0.0005 to $0.10
• Creating a token account: ~$0.20 (refundable)

For comparison, traditional payment systems often charge much higher fees, such as $15-$50 for wire transfers or $5-$10 for stock trades.

How Solana keeps fees low

Solana achieves low fees through its innovative design, including parallel processing and Proof of History (PoH). These mechanisms allow the network to process many transactions simultaneously without requiring extensive communication between validators. This design ensures that costs remain low, even as the network scales.
