• DEFINATION?
• What is mining? Why mining is required? Nonce basics ? None advanced?
• When a miner successfully finds the correct nonce, they create a new block with all the selected transactions, a reference to the previous block (creating the blockchain), and other necessary data. then each time they creting new block then?
• Here miners only finding correct nonce then when they check this transaction is correct or not ?

Sure! Here's a concise summary of the lesson on Ethereum Transactions and Gas (post-EIP-1559):

🧾 Ethereum Transactions & Gas — Summary

🔍 Key Concepts:

1. Wei & Gwei:
   • 1 Gwei = 1,000,000,000 Wei
   • 1 ETH = 1,000,000,000 Gwei
2. Transaction Fee = Gas Used × Gas Price
   • Gas Price = Base Fee + Priority Fee (Tip to miner)

⛽ Gas Breakdown:

• Gas Limit:

  Max gas a user is willing to allow for a transaction (set manually in MetaMask > Advanced > Edit Gas Limit)

• Base Gas Fee (post EIP-1559):

  • Dynamic (increases/decreases based on block congestion)
  • Burned to reduce supply and curb inflation

• Max Gas Fee:

  The maximum a user is willing to pay per gas unit.

• Max Priority Fee:

  The tip paid to miners to encourage faster inclusion.

• Block Confirmations:

  Number of blocks added after the one containing your transaction. More = higher certainty.
