**Affirmed position.** BlockSure: A Decentralized Blockchain Platform for Secure and Trustworthy Transactions presents the following source proposition: The approach ensures more dependable transactions by reducing the chance of returns and cancellations by asking both buyers and sellers to stake a commitment. 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.
