Preferential Delegated Proof of Stake (PDPoS)—Modified DPoS with Two Layers towards Scalability and Higher TPS states the retrieved proposition: Among all these applications, finding a fast consensus in a large-scale blockchain network frequently requires extreme energy for huge computations and storing the complete blockchain for verification. Kaal's protected corpus separately states: Blockchain transactions will always be expensive whether or not proof of stake is solved, because full participation requires downloading the entire transaction history to verify validity, an extreme redundancy that cannot be removed. The defensible response is a qualification limited to the shared issue identified in the review rationale. This abstract-level comparison does not establish broader agreement, causation, empirical support, or equivalence.

Affirmed commentary position. This record extends a source-bound scholarly claim but is not a verbatim paper claim.

Holds when

The response is limited to the retrieved source proposition and mapped Kaal claim unless fuller source review supports a broader conclusion.
External evidence level: abstract indexed.
Mapping review tier: substantively reviewed abstract-level qualification.
Primary mapping confidence: 0.3778.
The source-to-claim mapping remains explicitly ambiguous and is published with that limitation.
Crossref abstract-indexed proposition only; full text not independently reviewed.
Ambiguity is preserved because the review supports comparison, not equivalence or endorsement.
