PoSIGN consensus is achieved through the interactions between a system of real and virtual
node networks in constant communication, ensuring precise, rapid, signature-verified transactions .

In other words: Faster, stronger, more secure. You can read this article for some more information

This is from an interview with lead developer Borzalom :

Q2: Explain the Proof of Signature (PoSIGN) consensus algorithm. What are its benefits over Proof of Work or Proof of Stake algorithms? Why is it desirable?

A: The first thing that he talked about here is that Proof of Signature is green, it’s a very environmentally friendly algorithm like Proof of Stake as many of you know. We talk a lot about this in the slack and also on the forum about the different size laptops for example or different computers that are needed to run a STATIC node. We have explained that you can use an older machine and it doesn’t take a lot of power. This very good because as he’s talking about the Proof of Work miners for example they’re very energy intensive and we are not. That’s a very important thing for people to realize; then he moved on to the security so Proof of Signature is much stronger and more secure than Proof of Work because each Proof of Signature miner is trusted and audited so in this sense it’s better for the business environment than Proof of Stake or proof of work where miners are unknown. XBY wants to be a real business solution. peers and miners have to be non anonymous and we have to know who they are. That’s part of the trust factor that we have here at XBY, so all the static node miners are well known and they trust each other just like in the real business world … that’s a big key.
