Next, we see that this ledger is cryptographically-secure, which means that cryptography has been used to provide security services which make this ledger secure against tampering and misuse.
These services include non-repudiation, data integrity, and data origin authentication.
Why It’s Nearly Impossible to Hack
You will see how this is achieved later in , Symmetric Cryptography which introduces the fascinating world of cryptography.
Why This Matters for Blockchain Technology
Understanding Cryptographically-secure 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.
