Understanding the Problem and Possible Solutions

The provided configuration file is set to index transactions every 1, which means that bitcoind will periodically scan its blockchain for un-indexed transactions. However, if you’re trying to verify or audit your wallet without any of these un-indexed transactions being mined, this could be causing issues.

What Causes Un-Indexed Transactions?

Un-indexed transactions are those that have not yet been mined and are not part of the current block’s transaction list. These are often referred to as “pending” transactions.

Possible Solutions

1. Indexing Un-Indexed Transactions with txindex=0

You can set txindex to a value other than 1. For example, setting it to 0 means that bitcoind will only scan its blockchain for un-indexed transactions every block.

bitcoin.conf

#txindex=0

However, this solution may not be suitable if you need to verify or audit your wallet without any of the un-indexed transactions being mined. In such cases, setting txindex to 1 might still cause issues.

2. Using a Different Indexing Method

You can use txindex=0 along with txindex=0 and then periodically scan for unindexed transactions using other methods such as getunspentrawtransaction(0) or getindex(). However, this method involves additional complexity and is more likely to cause issues than the original solution.

bitcoin.conf

txindex=1

txindex=0

3. Removing Un-Indexed Transactions from the Blockchain

One potential issue with using txindex=0 or setting it in conjunction with other indexing methods is that bitcoind may remove un-indexed transactions from your blockchain to prevent them from being mined. This can be done by adding txindex=0 and then periodically scanning for unindexed transactions.

bitcoin.conf

txindex=1

getspendtransaction(0)

However, this solution requires that you have a large amount of unused data on your blockchain to scan through. It’s also worth noting that removing un-Indexed transactions will prevent them from being mined in the future.

Conclusion

The provided configuration file is set to index all transactions, which means bitcoind will periodically scan its blockchain for un-indexed transactions every 1 block. If you’re trying to verify or audit your wallet without any of these un-indexed transactions being mined, setting txindex=0 may cause issues.

To solve this problem, consider using a different indexing method, such as getunspentrawtransaction(0) and scanning for un-indexed transactions periodically, or removing unused data from the blockchain to prevent it from being mined.
