XPChain Core version 0.17.0-2 is now available from:

This is a new minor version release, with various bugfixes and translation updates.

Please report bugs using the issue tracker at GitHub:

How to Upgrade

If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/XPChain-Qt (on Mac).


XPChain Core is extensively tested on multiple operating systems using the Linux kernel, macOS 10.10+, and Windows 7 and newer (Windows XP is not supported).

XPChain Core should also work on most other Unix-like systems but is not frequently tested on them.

Notable changes

New RPC for listing states of minting

The listmintings RPC lists data of unspent transaction outputs (UTXO) and the states of minting, including coin-age of the UTXO, the probability of minting, and the expected amounts of the reward, which were displayed only in Qt wallet. You can filter the result similarly to listunspent, as well as by a minimum or maximum of coin-age.

Missing records in Minting tab

Some of the records of states of minting didn't show up in Minting tab when a transaction had two or more outputs to your addresses, because the record of one in the table overwrote those of the others. Now this is fixed so that you can see the complete list of the states.

St13runtime_error in minting

Your wallet sometimes caused EXCEPTION: St13runtime_error and failed to mint a new block when trying to create a block with one of your UTXOs. The function of proof-of-stake has been so fully refactored that this error will never cause.

GUI changes

  • In Minting tab, the setting for displaying probability within 90 days is replaced by that for within 60 days.
