1. Introduction to Bitcoin Transactions

• Objective: Provide a foundational understanding of Bitcoin transactions.
• Topics:
  [x] What is a Bitcoin transaction?
  [x] UTXO (Unspent Transaction Output) model.
  [x] Transaction inputs and outputs.
  [x] Transaction IDs and Hashing.
• Resources
  [x] https://learnmeabitcoin.com/technical/transaction/#structure
  [x] https://github.com/bitcoinbook/bitcoinbook/blob/develop/ch06_transactions.adoc#transactions
• Exercise: Create a simple visualization of a Bitcoin transaction, showing inputs, outputs, and the UTXO model.

2. Understanding Transaction Structure

• Objective: Dive deeper into the structure of a Bitcoin transaction.
• Topics:
  [x] Detailed breakdown of a transaction: Version, Inputs, Outputs, Locktime.
  [x]The role of scripts: ScriptSig and ScriptPubKey.
  [x] How transaction data is serialized.
• Resources
  [x] https://learnmeabitcoin.com/technical/transaction/#structure
• Exercise: Write a parser in your preferred programming language that reads and outputs the basic structure of a raw Bitcoin transaction (Version, Inputs, Outputs, Locktime).

3. Parsing Transaction Inputs

• Objective: Focus on the details of transaction inputs.
• Topics:
  [x] Structure of a transaction input.
  [x] Previous transaction hash, output index, scriptSig, sequence.
  [x] How inputs reference UTXOs.
• Resources
  [x] https://learnmeabitcoin.com/technical/transaction/input/
  [x] https://learnmeabitcoin.com/technical/transaction/input/scriptsig/
• Exercise: Extend your parser to extract and display detailed information about each input in a transaction.

4. Parsing Transaction Outputs

• Objective: Focus on the details of transaction outputs.
• Topics:
  [x] Structure of a transaction output.
  [x] Value and scriptPubKey.
  [x] Understanding P2PKH (Pay-to-PubKey-Hash) and other output types.
• Resources
  [x] https://komodoplatform.com/en/academy/bitcoin-script/
• Exercise: Extend your parser to extract and display detailed information about each output in a transaction.

5. Understanding Bitcoin Scripts

• Objective: Introduce students to Bitcoin's scripting language.
• Topics:
  [x] What is Bitcoin Script?
  [x] Commonly used opcodes.
  [x] How scripts are used in locking and unlocking transactions.
• Resources
  [x] https://wiki.bitcoinsv.io/index.php/Opcodes_used_in_Bitcoin_Script
  [x] https://komodoplatform.com/en/academy/bitcoin-script/
• Exercise: Extend your parser to have a simple script parser that can identify and parse common script types (e.g., P2PKH).

6. Constructing a Simple Transaction

• Objective: Guide students through creating a Bitcoin transaction.
• Topics:
  [x] Selecting UTXOs to spend.
  [x] Creating inputs and outputs.
  [x] Signing the transaction.
  [x] Serializing the transaction.
• Resources
  [x] https://www.ssldragon.com/blog/sha-256-algorithm/
• Exercise: Extend your code to construct a simple Bitcoin transaction from scratch using the parsed data from the previous exercises.

7. Transaction Signing

• Objective: Understand how Bitcoin transactions are signed.
• Topics:
  [x] Private keys and digital signatures.
  [x] How signatures are used to validate inputs.
  [x] Creating a valid transaction signature.
• Exercise: Extend your code to implement transaction signing and verify the signature against the input script.

8. Broadcasting a Transaction

• Objective: Learn how to broadcast a Bitcoin transaction to the network.
• Topics:
  [x] How transactions propagate through the Bitcoin network.
  [x] Tools and APIs for broadcasting transactions.
  [x] Exercise: Broadcast the transaction created in the previous exercise using a testnet or local Bitcoin node.

9. Advanced Transaction Types

• Objective: Explore more complex Bitcoin transaction types.
• Topics:
  [x] Multi-signature transactions.
  [x] P2SH (Pay-to-Script-Hash) transactions.
  [x] Segregated Witness (SegWit) transactions.
• Exercise: Write code to construct and parse one of these advanced transaction types.
