// 4096 unconfirmed messages (no any scientific justification for that - it just looks large
|
||||
// enough). And then we can't have more than 4096 relayers. E.g. for 1024 relayers is (using

// `RocksDbWeight`):
|

//
|

// `1024 * (8_000_000 + db read + db write) = 1024 * (8_000_000 + 25_000_000 + 100_000_000) =
