Bitcoin Rescanning with Bitcoin Core 28: A Guide

Introduction

Bitcoin Core 28 is the latest version of the open-source Bitcoin client software, released in June 2022. One of the key features of Bitcoin Core 28 is its improved performance and efficiency compared to previous versions. However, this new version also introduces some changes that may require manual intervention to achieve similar results as re-indexing.

Rescanning: What is it?

Rescanning, also known as rebalancing or rescanning, is a process in Bitcoin where the blockchain is updated to ensure that all transactions are properly recorded and reflected on the network. This involves verifying and synchronizing the entire transaction history, which can be time-consuming for some users.

Why Rescanning May Not Work with Bitcoin Core 28

Bitcoin Core 28 has made several changes to its rescanning process, including:

• Improved Disk Scheduling

  : The new disk scheduling algorithm used by Bitcoin Core 28 provides improved performance and efficiency for rescanning operations.

• New Block Format: Bitcoin Core 28 uses a new block format that is more efficient than the previous one, reducing the amount of data transferred during the rescanning process.

Rescanning with Bitcoin Core 28: Alternatives to Reindexing

While re-indexing may still be the recommended approach for most users, there are a few alternatives you can try if you encounter issues:

Option 1: Manual Rescanning

If you want to manually rescan your Bitcoin wallet and ensure that all transactions are being recorded correctly, you can use a combination of the bitcoin-cli command-line tool and downdog software.

Here’s how:

• Download and install the downdog software from [the official website](

• Run the downdog software on your local computer, giving your Bitcoin Core 28 wallet file as input.

• The downdog software will create a new rescan directory and update all transactions in your wallet to reflect on the network.

Option 2: Use the bitcoin-cli command

You can also use the bitcoin-cli command line tool to manually rescan your Bitcoin wallet. Here’s how:

• Run the bitcoin-cli command with the following options:

rescan  --format=

Replace with the path to your Bitcoin Core 28 wallet file, and with one of the following formats: blockchain, db, or json.

Option 3: Use a Third-Party Tool

If you want a more automated approach, you can use a third-party tool like [BTCRescan](

These tools allow you to rescan your Bitcoin wallet and update all transactions to reflect on the network. However, they may require additional configuration and settings.

Conclusion

While reindexing is still the recommended approach for most users, there are alternative methods available if you are having trouble with the new Bitcoin Core 28 reindexing process. Using a combination of bitcoin-cli commands or third-party tools, you can manually reindex and ensure that your Bitcoin wallet is properly updated to reflect the network.

It is important to note that manual reindexing may not be suitable for all users, especially those with large wallets or complex transaction histories. In such cases, reindexing may still be the best option.
