Bitcoin Testnet Files Documentation: Burn Transactions and Headers

This document provides descriptions of two key test files used in Bitcoin-related testing, particularly for validating burn transactions and block headers in the context of BitcoinExchange logic. These files support various test scenarios involving the Bitcoin testnet.

bitcoin_testnet_blocks_containing_burn.txt

Purpose: Contains Bitcoin testnet blocks that include "burn" transactions. Burn transactions are defined as those sending funds to the testnet burn address (a designated address for permanently removing bitcoins from circulation, often used in testing or protocol mechanisms).
Usage: These blocks and their corresponding transactions are referenced in various tests that exercise the BitcoinExchange logic. This allows for simulation of real-world scenarios involving burn operations, such as validating transaction finality, exchange rate impacts, or blockchain integrity checks.

This file is essential for unit and integration tests where the presence of burn transactions in blocks needs to be verified, ensuring the exchange logic handles such irreversible operations correctly without errors or exploits.

bitcoin_testnet_headers_for_burn.txt

Purpose: Contains block headers associated with the blocks mentioned in bitcoin_testnet_blocks_containing_burn.txt, as well as headers for a large section of blocks before and after these specific blocks. This provides contextual chain data for comprehensive testing.
Usage: These headers are used for testing various scenarios related to BitcoinExchange transaction validation. For example, testing when a burn transaction does not have enough proof-of-work (PoW) accumulated on top of it to be considered valid, or simulating chain reorganizations around burn events.

This file enables edge-case testing, such as insufficient work validation, header chain integrity, and exchange-specific rules for confirming transactions in a testnet environment. It supports scenarios where headers are fetched or validated independently of full blocks.

Note: These files are typically used in a development or testing environment for Bitcoin software, such as custom exchanges or wallets. Ensure compliance with Bitcoin testnet guidelines and handle data securely to avoid any real-network implications.
