Also, as stated, I'm not a marketeer so you reading too much into a cheesy tagline shows me you fail to actually pull out content from posts well. You asked to describe what dpow was without using stake... in simplest terms with an albeit cheesy slogan, that's its selling point. For projects that lack the infrastructure to adequately protect their chain, for a relatively small price, they can prevent attack by periodic snapshots to the longest, most secure ledger in the world. While not backed up directly, we can say with the transitive property that they ultimately exist on the BTC ledger because the ultimate hash encompasses those chains. Finally, I wasn't aware that Tether secured blockchains from attack. Thanks for the info. /s
