When dealing with cryptocurrencies such as bitcoin, privacy is always a top priority. One of the ways to achieve privacy is through the use of addresses. Bitcoin addresses are used to send and receive Bitcoin payments. However, not all bitcoin address information is appropriate for public consumption. Some of the fields returned by getaddressinfo are not intended for public use. In this article, we will discuss the non-public fields returned by getaddressinfo and how to use them to enhance your privacy.
Understanding getaddressinfo
getaddressinfo is a Bitcoin Core RPC command used to get information about a Bitcoin address. The command returns a JSON object with various fields such as address, balance, and unconfirmed balance. These fields are intended for public use and are commonly displayed on blockchain explorers and similar services.
However, there are other fields returned by getaddressinfo that are not intended for public use. These fields contain sensitive information that should only be accessed by the owner of the address. These non-public fields include
Non-public fields returned by getaddressinfo
hdmasterkeyid
This field contains the identifier of the HD (Hierarchical Deterministic) master key used to generate the address.This field is not intended for public use as it can be used to derive all the child keys of the master key, which could compromise the security of the address.
Label
This field contains the user-assigned label for the address. While this information may not be sensitive, it is not intended for public consumption as it may reveal the identity of the address owner.
resolvable
This field indicates whether or not the private key for the address is known. This information is sensitive because it can be used to access the funds in the address.
Witness Program
This field contains the witness program used to generate the SegWit address. This information is not intended for public use as it can be used to reverse engineer the private key of the address.
Privacy enhancement with non-public fields
While the non-public fields returned by getaddressinfo are not intended for public use, they can be used to enhance privacy. For example, the hdmasterkeyid field can be used to identify all addresses derived from the same HD master key. This can be useful for creating a more private payment network, since all addresses in the network can be traced back to a single HD master key.
Similarly, the Label field can be used to group addresses for easier management and accounting. This can be useful for businesses that deal with a large number of addresses.
The solvable field can also be used to enhance privacy by identifying addresses with unknown private keys. These addresses can be considered more private because they cannot be accessed without the unknown private key.
Finally, the witness_program field can be used to identify SegWit addresses. SegWit addresses are more private than legacy addresses because they use a different transaction format that allows for more efficient use of block space. By identifying SegWit addresses, users can ensure that they are using the most private address format available.
Conclusion
In summary, the non-public fields returned by getaddressinfo contain sensitive information that is not intended for public consumption. However, these fields can be used to enhance privacy by providing additional information about the address. It is important to understand which fields are sensitive and which are not in order to ensure that your bitcoin address information is kept private and secure. By using the non-public fields returned by getaddressinfo, users can take their privacy to the next level and ensure that their Bitcoin transactions are as private as possible.
