The BPX Chain mainnet is experiencing a serious outage. This morning, after reaching block height 412026, most Beacon Chain nodes stopped generating and validating new blocks, leading to a sudden drop in block rate to one block every few minutes.

All we know at this moment is that certain conditions triggered a bug that caused persistent inoperability (remaining after restarting the client) of all nodes running on Windows systems. Since Windows nodes make up the majority of the BPX Chain netspace, they are all offline, leaving the blockchain significantly weakened. Other nodes with different operating systems are still operational but struggling with excessively high difficulty, which impacts performance and stability.

While the root cause of the outage is not yet known, a temporary fix is available. Affected nodes can regain functionality by replacing their blockchain database with a file from another node that has synchronized beyond block 412026.

To apply the workaround, follow these steps:

  1. Stop the Beacon Client
  2. Download the blockchain database synchronized to the post-outage state:

    Alternatively:
    💾 https://download.bpxchain.cc/blockchain_v1_mainnet.sqlite
  3. Replace the file located at C:\Users\???\.bpxchain\beacon\db\blockchain_v1_mainnet.sqlite with the downloaded one.
  4. Start the Beacon Client

We are actively investigating the root cause of this issue and will release a fixed client as soon as possible. A detailed case analysis will follow once the issue is resolved. Stay tuned for further updates.
