Syscoin Core 4.4.2

Syscoin Core installation binaries can be downloaded from and the source-code is available from the Syscoin Core source repository.

4.4.2 Release Notes

Syscoin Core version 4.4.2 is now available from:

Hot Fix for the following issues:

  • coincontrol issues not selecting the right amounts and crashing if using the “use available balance” button
  • presync looping (i think was geth in invalid state, so we just disable geth connection for the sync)
  • sendrawtransaction (for sys burn to nevm we skip the max burn check). This should fix pali/blockbook
  • gobject_prepare fix which wasn’t signing before sending the transaction. Useful for people creating governance proposals
  • Large rollback on nevm fix, which causes general issues related to pruning PoDA when transaction is removed from mempool as a “reorg”, we shouldn’t do this because upon subsequent block validation the block will not validate.

Note: Masternode operators should upgrade their sentinel to v4.4.0

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/Syscoin-Qt (on Mac) or syscoind/syscoin-qt (on Linux).

If you are upgrading from a version older than 4.2.0, PLEASE READ:


Syscoin Core is supported and extensively tested on operating systems using the Linux kernel, macOS 10.15+, and Windows 7 and newer. It is not recommended to use Syscoin Core on unsupported systems.

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

From Syscoin Core 4.4.0 onwards, macOS versions earlier than 10.15 are no longer supported.



Thanks to everyone for the continued support of Syscoin
