Logging Operations: A Complete Guide to Understanding This Blockchain Concept

Logging operations provide opcodes to append log entries on the substate tuple’s log series field.

There are four log operations available in total, and they range from value 0x0a to 0xa4.

A Complete Guide to Understanding This Blockchain Concept

Mnemonic Value POP PUSH Gas Description 375, Used to append log record with N topics, where N is the 750, number corresponding to the LOG opcode used.

For example, LOG0 means a log record with no topics, and LOG4 LOG0 .

X and Y represent the LOG4 …0xa4 items removed and placed on the stack, respectively.

X 1500, and Y change incrementally, starting from 2, 0 up to 6, 0 according to the LOG operation used.

Why This Matters for Blockchain Technology

Understanding Logging 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.
