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

4.4.1 Release Notes

Syscoin Core version 4.4.1 is now available from:

This is a hot fix release for users of Syscoin Core on OSX ARM M1/M2 and Windows:

  1. Non-supported geth systems like arm OSX M1/M2 should not run geth at all and shouldn’t stop at blocks that require NEVM
  2. Prune was being enabled on some systems by default which disabled governance which led to coinbase-pays-too-much error which we fixed
  3. Windows installer puts binaries in a new location (daemon directory) and we correctly look for sysgeth there on startup You should just install and run, if you were previous stuck on a block you can reindex to fix.

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