Every 10 minutes on average, a new block is added to the Bitcoin blockchain. Let's explore how this process works.

The Block Creation Process:

1. Transaction Pool: Unconfirmed transactions wait in the mempool 2. Block Assembly: Miners select transactions to include 3. Mining Competition: Miners race to find a valid hash 4. Block Discovery: A miner finds the solution 5. Propagation: The new block spreads across the network 6. Verification: Nodes validate the block 7. Chain Extension: The block is added to the blockchain

Block Rewards:

•Miners receive newly created Bitcoin (currently 6.25 BTC)
•Plus all transaction fees from included transactions
•Block reward halves every 210,000 blocks (≈4 years)
