[BUG]Persistent Sync Errors due to Invalid Transaction Proof Verification in xelis_daemon #93

Closed Aljebaay closed 2 months ago

Aljebaay commented 2 months ago

Describe the bug The xelis_daemon exhibits repeated synchronization issues, specifically showing errors related to "Invalid transaction proof: proof verification failed" during the blockchain sync process. This occurs consistently with various peers and prevents successful data synchronization.

Version used 1.14.0-7056f59

To Reproduce Steps to reproduce the behavior:

  1. Start the daemon with the following command: xelis_daemon.exe --allow-boost-sync
  2. Observe the logs as it attempts to sync with peers.
  3. The error appears intermittently during the sync process, particularly noted in the peer-to-peer synchronization phase.

Expected behavior I expected the daemon to sync without any issues and validate transaction proofs correctly without resulting in synchronization failures.

Additional context The issue has been persistent despite attempts to restart the daemon and verify network settings. Here are some relevant log excerpts showing the error:

Hello this is a known bug,

try « pop_blocks 10 » in the daemon to delete the last 10 blocks and it will try to sync again. You may have to do it multiple times based on which peer he will select to sync with.
