🔍 What is UTXO?

Unspent Transaction Output (UTXO) is the foundation of Bitcoin’s transaction system, keeping track of unspent cryptocurrency after each transaction. Think of it as getting change after a cash purchase — the leftover balance becomes spendable for future transactions. 💰

🔗 How Does UTXO Work?
Bitcoin uses the UTXO model instead of a traditional account balance system. Every transaction consists of inputs (spent coins) and outputs (remaining coins). The blockchain tracks these outputs, ensuring security and preventing double spending.

Benefits of UTXO:

• Enhanced privacy & security 🔐 — addresses track transactions, not users.

• Prevents double spending — each UTXO can only be used once.

• Lower fees over time — UTXO consolidation groups small balances into larger ones, reducing future costs.

⚠️ Limitations of UTXO:

• Frequent consolidation needed, leading to extra transaction fees. 💸

• More complex to understand compared to account-based models like Ethereum.

• Less fungibility, making transactions harder to manage.

🚀 Why Does UTXO Matter?
The UTXO model ensures Bitcoin’s security, privacy, and decentralization, setting it apart from Ethereum’s account-based system. While it has some inefficiencies, it remains a key innovation in blockchain technology. 🔥
