Syscoin Core 4.4.1
Syscoin Core installation binaries can be downloaded from syscoincore.org 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:
- Non-supported geth systems like arm OSX M1/M2 should not run geth at all and shouldn’t stop at blocks that require NEVM
- Prune was being enabled on some systems by default which disabled governance which led to coinbase-pays-too-much error which we fixed
- 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
