May 10, 2017 at 9:33 comment added Edmund Edgar It's probably mostly because these systems are ported from public blockchains. In a public blockchain empty blocks help by extending the number of confirmations of transactions in previous blocks, making them less likely to be reversed. And there are nearly always transactions in any case, and even if there weren't the miner would still want their block reward. On private blockchains they're arguably less useful - I know of one implementation, Hydrachain, that only makes blocks if there are transactions.
