# 🔗 Solana vs Other Chains — Practical Blockchain Integration Series

Welcome to an open-source deep dive into **how building on Solana** compares with other blockchains like **EVM (Ethereum, BSC, Polygon)**, **Aptos**, **Cardano**, **Bitcoin**, **Near**, and **Sui**.

> 🤔 Is Solana easy or complex to build on? How does it really compare with other ecosystems in terms of cryptography, wallet creation, and transaction flow?

This repo explores that question—**one module at a time**, with working code examples and architecture comparisons across chains.

## 🧠 Must-Read Before Diving In

Before diving into the code, I *highly* recommend reading this article:  
**👉 [Understanding Elliptic Curve Digital Signature Algorithm (ECDSA, EdDSA, etc.)](https://2finance.medium.com/understanding-elliptic-curve-digital-signature-algorithm-ecdsa-secp256k1-and-eddsa-curve25519-56ff82fc4f74) **

It gives essential context on **cryptographic key generation**, helping you understand **why each chain behaves the way it does** under the hood.

## 🚀 Modules (More Coming Soon)

### 1. **🧪 Create Wallet (Compare: Solana vs Others)**

This module shows how wallet keypairs are generated on each chain using their SDKs.  
We compare:
- Keypair structure (private/public)
- Underlying cryptographic curves (e.g., secp256k1 vs ed25519)
- Output format differences
- Ease of use & abstraction level

#### 📂 Structure:
```bash
create_wallet/
├── sol.ts                 # Solana wallet creation using @solana/web3.js
├── other_chains/
│   ├── evm.ts             # EVM wallet using viem
│   ├── aptos.ts
│   ├── bitcoin.ts
│   ├── cardano.ts
│   ├── near.ts
│   ├── sui.ts

📊 Summary Table

Step	💠 EVM (via viem)	🟣 Solana (via @solana/web3.js)
1. Generate Keypair	generatePrivateKey() (32-byte secp256k1)	Keypair.generate() (64-byte ed25519)
2. Derive Address	From key → EVM checksum address	From publicKey → base58 address
3. Output Secret/Private	Returns raw 32-byte hex	Returns 64-byte (public + private) in hex

2. 📥 Import Wallet — "One mnemonic to rule them all..."

Inspired by the timeless words of Tolkien:

"One mnemonic to rule them all, one mnemonic to find them, One mnemonic to bring them all, and in the blockchain bind them."

This module will showcases:

• How to derive wallets from a mnemonic phrase
• Differences in derivation paths (BIP44, SLIP-0010, etc.)
• Unique behaviors in chains like Solana (ed25519) vs EVM (secp256k1)

🌐 Why This Repo?

Let’s be honest—Solana gets a lot of attention, but many devs still ask:

"Is it really worth the hype?"
"How does it stack up against EVM or Aptos or Cardano?"

This repo exists to answer those questions with code, not opinions.

Here’s the thing:
✅ Solana isn’t just fast—it’s architecturally different.
✅ Transactions are parallelized, not sequential.
✅ The keypair system is compact and insanely efficient.
✅ Fees are almost nonexistent, yet you get finality in seconds.
✅ It’s built for performance, not just compatibility.

But—every chain has its strengths.
That’s why we’re doing real side-by-side comparisons: wallet creation, signing, transactions, and more.

Whether you're a dev exploring Solana or building cross-chain apps, this repo helps you truly understand the "why" behind the "wow".
