This is where most people stop learning — but not you.
Today we dive into one of the more technical areas of Bitcoin.
It might seem complex at first, but understanding this gives you confidence and clarity.
Let’s break it down simply.
📦 Think of Bitcoin as a digital notebook
This notebook records every transaction on the network — forever.
But who writes the pages?
Enter the:
-
Mempool
-
Blocks
-
Miners
🕒 What is the mempool?
The mempool is like the waiting room at a post office.
When you send Bitcoin:
-
It enters the mempool
-
It waits to be picked by a miner
-
Higher-fee transactions are processed first
Miners select the most profitable transactions to include in the next block.
🔍 What is a block?
A block is like a full page of recent transactions.
Roughly every 10 minutes, a new block is added to the blockchain — the permanent public ledger.
⛏️ What do miners actually do?
Miners are like digital notaries or postal clerks:
-
They gather unconfirmed transactions from the mempool
-
Compete to solve a math puzzle (called proof-of-work)
-
The first to solve it:
-
Adds the block to the blockchain
-
Earns newly minted Bitcoin
-
Plus transaction fees
-
📜 Why does it matter?
-
Security: Transactions become tamper-proof
-
Decentralization: Anyone can mine — there’s no central authority
-
Stability: One block every ~10 minutes keeps the system running smoothly
Summary
✅ The mempool is Bitcoin’s transaction waiting room
✅ A block is a new page in the ledger
✅ Miners confirm and secure every transaction
Coming up tomorrow
We’ll explore how miners are rewarded, and what happens when the Bitcoin supply slows down.
Yes — we’re talking about the halving.
