You are right. It should be possible to run hived on lower end machines with pruned block_log.
I should have probably mentioned that as well. Thanks.
I remember not being able to run hived with 8gb of ram but I think that was building from the source. I didn't think about it that much as with this one I was aiming for seed nodes and I don't think running a public seed node without the block_log would be that beneficial. But for other uses, it is valid.
