- 12. Blockchain ● Distributed ledger with lists of records (blocks) linked together. ● Operates on a peer-to-peer network. ● Every node (participant) has a copy of entire ledger. ● Once a transaction is recorded, it cannot be altered.

Bitcoin ● Decentralized Digital Asset ● Introduced in 2009 by an anonymous group of developers using the name Satoshi Nakamoto ● Operates on a decentralized network ● Transactions recorded on a public ledger called the blockchain. ● Offers a potential alternative to traditional banking systems.

- 27. Mempool - Bitcoin Explorer ● short for "memory pool" ● Enables to view real-time and historical information about a node's mempool ● Visualize its transactions ● search and view those transactions ● Free and Open Source Software ● Self hosted-No trusted third party
- 29. ● Forecasted or Projected Blocks-blocks in process of being mined ● Confirmed Blocks-mined blocks (Transaction successfully added to blockchain)
- 30. Block height : position of a block within the chronological sequence of blocks in blockchain Average Fee rate paid per block Range of fee paid by users Total amount of Bitcoin in transaction Total number of transaction Time when transaction confirmed Group of miners mined the block
- 31. Block
- 32. Expected and Actual Block ● Mempool monitors mempool view, running Bitcoin Core's algorithm every 2 seconds. ● Snapshot of expected block saved at new block mining, serving as next block's template.
- 33. ● Highlighted transactions convey various heuristics: ○ Added: Blue for transactions prioritized by the miner or accepted out-of-band. ○ Recently Broadcasted: Dark pink for transactions first seen within 3 minutes of block mining. ○ Marginal Fee: Darkened for low-end feerate transactions displaced from blocks. ○ Removed: Bright pink for transactions intentionally excluded from blocks.
- 34. Transactions
- 36. Empty Blocks
- 37. Genesis Block
- 39. Activity 1 ● Get the number of Empty Blocks in last 12 hours ● From the pools ranking find the number of blocks mined by F2Pool ● Find the block number having the highest transactions in last 1 hour and get the nonce value for it
- 40. Activity 2 ● Identify the size of the 'Bitcoin Pizza Day' transaction ● Determine the fees paid to the miner ● Find the timestamp of the transaction ● Locate the transaction ID ● How many Bitcoins were exchanged for the two pizzas ● Calculate the current value of those Bitcoins today
- 41. Activity 3 ● Find the block number of the third Bitcoin halving ● Analyze block sizes before and after the third halving ● Get no. of transactions in the third halving block ● Determine the miner reward in the third halving block.
