Hi team,

I found an unexpected behavior when running the Midnight Indexer on two different servers.

Both servers:

• run the same version of the Indexer
• use identical configs (same environment, same chain, same docker compose profile, same settings)
• connect to the same network
• are syncing without errors

However, when I compare the Postgres databases, I see that the blocks table has different author values for the same block height between the two servers.

Specifically:

• hash,protocol_version, parent_hash and timestamp fields same data
• but the author field is different between the two machines

❓ My question:

• Why can this field differ?
• Where exactly does the author value come from (which part of the node / protocol / metadata)?
• Is there documentation explaining this field and how it is derived?

Thanks for your guidance!
