Add Bitcoin Transaction Course Module

Course Title: Build and broadcast your own Bitcoin transaction Modules:

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.
