In the world of cryptocurrencies, bitcoin is the most popular and widely used. Bitcoin Core is the official reference client for the Bitcoin network, a software application that implements the Bitcoin protocol. Output Script Descriptors are a feature in Bitcoin Core that makes it easier to work with complex transaction types. However, there’s a common question that has come up in the Bitcoin community, which is Why does listdescriptors produce different XPub keys for a brand new wallet in Bitcoin Core?
The basics of ListDescriptors
Output script descriptors in Bitcoin Core are a way to describe a set of output scripts using a concise syntax. This syntax is used to generate a list of potential output scripts, which can then be used to generate both public and private keys. ListDescriptors is a way to define a set of descriptors using a single string that can be used to generate multiple keys.
The syntax for ListDescriptors is quite simple. It starts with a base descriptor that defines the type of keys to be generated. This base descriptor can be followed by additional descriptors that modify the behavior of the base descriptor. These additional descriptors can be used to add constraints, such as requiring that a key be derived from a particular branch of a tree.
XPub keys and list descriptors
XPub keys are advanced public keys used to create hierarchical deterministic wallets (HD wallets). These keys are generated from a master seed that is used to derive a hierarchy of child keys. These child keys can be used to generate new Bitcoin addresses that can be used to receive payments.
When using ListDescriptors to generate XPub keys for a new wallet in Bitcoin Core, the keys generated may be different from what you expect. This is because the keys are generated based on the derivation path used by the wallet. The derivation path is a set of rules that determine how child keys are derived from the parent key.
For example, if you use the default derivation path in Bitcoin Core, the XPub keys generated will be different from those generated using the derivation path used by any other wallet software. This is because different wallets may use different derivation paths, resulting in different XPub keys being generated.
Why ListDescriptors produce different XPub keys for a brand new wallet in Bitcoin Core
The reason why ListDescriptors returns different XPub keys for a brand new wallet in Bitcoin Core is that the keys are generated based on the derivation path used by the wallet. This derivation path is determined by the software used to create the wallet, as well as any additional parameters specified when creating the wallet.
For example, if you create a new wallet using Bitcoin Core and specify a custom derivation path, the XPub keys generated will be different from those generated using the default derivation path. This is because the derivation path is used to generate the keys, and different derivation paths will result in different keys being generated.
Another factor that can affect the generation of XPub keys using ListDescriptors is the version of Bitcoin Core you are using. Different versions of the software may use different default derivation paths, which may result in different XPub keys being generated.
Conclusion
In conclusion, ListDescriptors are a powerful feature in Bitcoin Core, making it easier to work with complex transaction types. However, the generation of XPub keys using ListDescriptors can be affected by a number of factors, including the derivation path used by the wallet and the version of Bitcoin Core being used. It’s important to understand these factors when working with ListDescriptors in Bitcoin Core to ensure that the keys generated are the ones you expect.
FAQs
What are Output Script Descriptors in Bitcoin Core?
Output Script Descriptors in Bitcoin Core are a feature that makes it easier to work with complex transaction types. They allow users to define a set of output scripts using a concise syntax, which can then be used to generate both public and private keys.
What are XPub keys?
XPub keys are extended public keys that are used in the creation of hierarchical deterministic wallets (HD wallets). They are generated from a master seed, which is used to derive a hierarchy of child keys. These child keys can be used to generate new Bitcoin addresses, which can be used to receive payments.
How are XPub keys generated using ListDescriptors?
XPub keys are generated using ListDescriptors by defining a set of descriptors using a single string, which can be used to generate multiple keys. The syntax for ListDescriptors is relatively simple, and starts with a base descriptor that defines the type of keys to be generated. This base descriptor can be followed by additional descriptors, which modify the behavior of the base descriptor.
Why does ListDescriptors yield different XPub keys for a brand new wallet in Bitcoin Core?
ListDescriptors yield different XPub keys for a brand new wallet in Bitcoin Core because the keys are generated based on the derivation path used by the wallet. This derivation path is determined by the softwareused to create the wallet, as well as any additional parameters that are specified during the creation of the wallet. Different wallets may use different derivation paths, which can result in different XPub keys being generated.
How can the generation of XPub keys using ListDescriptors be influenced?
The generation of XPub keys using ListDescriptors can be influenced by a number of factors, including the derivation path used by the wallet, the version of Bitcoin Core being used, as well as any additional parameters specified during the creation of the wallet.
What is the default derivation path used by Bitcoin Core?
The default derivation path used by Bitcoin Core is m/0’/0′. This derivation path is used to generate XPub keys for new wallets by default. However, users can specify a custom derivation path during the creation of a new wallet, which will result in different XPub keys being generated.
How can users ensure that the XPub keys generated using ListDescriptors are the ones they expect?
Users can ensure that the XPub keys generated using ListDescriptors are the ones they expect by understanding the factors that can influence their generation. This includes understanding the derivation path used by the wallet, the version of Bitcoin Core being used, and any additional parameters that are specified during the creation of the wallet.
