Asset txns vs empty txns

Question

Does the mining operation distinguish txns in which a asset is affected vs txns in which there isn't any asset transfer?

Are the non-asset transfer txns any less secure(can data in it be altered?)  than a txn which has a asset transfer?

Answer 1

There is no difference in these two types of transactions from the perspective of mining or security in the blockchain. In either case a transaction is just a lump of data that gets embedded in a block (after being verified for validity).
