When is Blockchain Needed presents the following source proposition: This reputation has been attributed to its properties of allowing data to be shared across a large network of untrusted entities without relying on a trusted third party. This proposition is pertinent to Kaal's source-bound claim that A malicious party using Sybil accounts cannot be prevented from cloning the structure of a successful proof of stake blockchain at far lower cost than cloning a proof of work chain, leaving a new user unable to distinguish the truly decentralized chain from a clone that has manufactured even more tokens. The authors answer that this is resolved off chain, by a trusted user interface, as with cloned web pages. The proposed response is an extension: the relationship should remain limited to the retrieved source proposition and the mapped Kaal claim unless fuller source review supports a broader conclusion.
