Nikhil Chandhok, CTO of Circle, detailed ARK's technical differentiators, including permissionless contract deployment despite a permissioned validator set, upcoming beta support for post-quantum signatures, and a privacy sector enabling users to switch between public and private transactions seamlessly using the same wallet interface.
“the deployment of contracts is not permission. Like so anybody can come deploy. You don't need a developer key from us. You don't need like you don't need to sign up a circle. So in that way, it is very much permissionless deployment.”
“We announced that we're going to be doing post-quantum signatures. It should launch in beta. very soon.”
“What we want to do is do something as simple as like you toggle a switch and you can take a transaction that was going to be a public transaction and make it a private transaction. So you can have a mix of both public and private transactions using the same wallet interface. That's unique.”
