Finite Fields in Cryptography: The Math That Makes Blockchain Security Possible (Part 2)

A prime field is a finite one with a prime number of elements.

It has specific rules for addition and multiplication, and each nonzero element in the field has an inverse.

The Math That Makes Blockchain Security Possible (Part 2)

Addition and multiplication operations are performed modulo p, that is, prime.

Prime fields A prime field is a finite one with a prime number of elements. It has specific rules for addition and multiplication, and each nonzero element in the field has an inverse. Addition and multiplication operations are performed modulo p, that is, prime.

Why This Matters for Blockchain Technology

Understanding Prime fields 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.
