BIP 174 Partially Signed Bitcoin Transactions Support

Thanks in part to Andrew Chow for the work in GitHub for the code, BIP 174 PSBTS is now live in Bitcoin Core 0.17.0. This is an interchange format to work with Bitcoin transactions that are not yet fully signed. By using the partially completed work and relevant metadata the transaction can be signed. This is meant to simplify the process in which more than one party must work together to form a transaction.


  • Hardware Wallets
  • Multisignature Setups
  • CoinJoin Transactions


Now Non-HD Wallets Can be Upgraded to HD

BIP 32 Hierarchical Deterministic (HD) wallets have been supported by Bitcoin Core since version 0.13.0, however, older non-HD could not be converted. This changed today with Bitcoin Core 0.17.0, now non-HD wallets can be converted into HD wallets using a specific input in the command line. The notes say that a new backup must be made when upgrading the non-HD wallet to the HD wallet so keep this in mind when making this change.

HD Master Key Rotation

Now Bitcoin Core allows for the creation of new HD-seeds. Once a seed is re-created the wallet must be backed up.

Dynamic Loading and Creation of Wallets

No longer do you have to shut down your Bitcoin Core client to load or create a new wallet. Loading, creating or unloading a wallet can be done with a simple command. Currently, this feature is only available in the RPC interface.

Some GUI/Config Changes

There have been some changes in how the client looks and may take a small amount of time to get used to the changes.

Log Timestamp Format is Now ISO 8601

The new Bitcoin Core timestamp is now is ISO 8601. This means the date and time of each transaction now follow this format “2018-02-28T12:34:56Z”. This may be the least interesting of the updates but it is good to stay abreast to the latest updates in Bitcoin Core.

Dropped Support for Python 2

Support for Python 2 has been discontinued for all test files and tools.
