Understanding the problem and possible solutions

The provided configuration file is configured to index transactions every 1, which means that bitcoind will periodically scan its blockchain for unindexed transactions. However, if you try to verify or audit your wallet without any of these unindexed transactions being mined, this can cause problems.

What causes unindexed transactions?

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

Possible solutions

1. Index unindexed 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 unindexed transactions each block.

bitcoin.conf
#txindex=0

However, this solution may not be suitable if you need to verify or audit your wallet without any unindexed transactions being mined. In such cases, setting txindex to 1 may still cause problems.

2. Using an alternate indexing method

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

bitcoin.conf
txindex=1
txindex=0

3. Removing unindexed transactions from the blockchain

A potential problem with using txindex=0 or setting it in conjunction with other indexing methods is that bitcoind may remove unindexed transactions from your blockchain to prevent them from being exploited. This can be done by adding txindex=0 and then periodically checking for unindexed transactions.

bitcoin.conf
txindex=1
getunspentrawtransaction(0)

However, this solution requires that you have a large amount of unused data on your blockchain to analyze. It should also be noted that removing unindexed transactions will prevent them from being exploited in the future.

Conclusion

The provided configuration file is configured to index all transactions, which means that bitcoind will periodically scan its blockchain for unindexed transactions every block. If you are trying to verify or audit your wallet without any of these unindexed transactions being mined, setting txindex=0 may cause problems.

To resolve this issue, consider using an alternate indexing method, such as getunspentrawtransaction(0) and periodically scanning for unindexed transactions, or removing unused data from the blockchain to prevent it from being mined.
