As the name suggests, duplication operations are used to duplicate stack items.
Items placed on the stack or removed from the stack also change incrementally with the mnemonic used; for example, DUP1 removes one item from the stack and places two items on the stack, whereas DUP16 removes 16 items from the stack and places 17 items.
A Complete Guide to Understanding This Blockchain Concept
Mnemonic Value POP PUSH Gas Description Used to duplicate the Nth stack item, where N is the D D U U P P 1 1 6 .
X and Y are the items removed and placed on the stack, respectively.
Why This Matters for Blockchain Technology
Understanding Duplication operations is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
