Well from my four year experience with DPoS it seems to me to be the playground of blockchain technology compared to proof of work chains. There are too many reasons and not enough interest to bother explaining here. My powering down on both HIVE and STEEM should indicate the opinion of one that has been involved in crypto since 2012 or a bit before.

You may be interested in another serious vulnerability being worked on in my lab for witnesses of on DPoS social media blockchains. It is being demonstrated in my recent post of images being posted directly to the blockchain itself in base64 format.

More information will be forthcoming, on this account, of how to unencode such images for those not familiar with base64 encryption.
