Ethereum Transaction Analysis: Understanding Open OP Codes
As a Python developer, you are likely to know the unique event form of Ethereum Blockchain. When dealing with events that contain non-standard TXs (transactions) and obscure op codes, they can be challenging to understand them.
In this article, we explore the world of Ethereum events and explore some examples of non-standard TX with unclear OP codes. We also offer explanations and insights that will help you better understand these mysterious blocks.
What is the event (TX) in Ethereum?
The event in the Ethereum block chain consists of several components:
- Title : The title includes metadata about the event, such as the sender’s public address, the recipient’s public address and the gas limit.
- Frame : The frame contains actual information that is transferred between accounts.
- Witness : A witness is a small added value to the body’s body to check its accuracy.
OP CODE UNDERSTAND
OP codes are an important part of Ethereum events. They represent the instructions that the Ethereum virtual machine (EVM) can be performed. Here are some general OP codes:
0x00: No activity
0x01: Push the constant
0x02: the push variable
0x03: CALL function
0x04: Reduce
0x05: Tell
0x06: Share
0x07: module
0x08: Get field compensation
0x09: Set field transfer
Examples of non-standard TX with unclear OP codes
Let’s take an example you presented:
Scriptpubkey:" ...
Txhash: 77822fd6665104119cb76352756dfc50da76a92d417ec1a12c518fad69 "
Here are some examples of non-standard TX with unclear OP codes that may give you a glimpse of this mysterious block:
- 0x00000001
: This op code is used to push the standard value into a stack. In this case, the value that represents the transactionhash (eg the hexadecimal presentation of the block number) is likely to be pushed.
- 0x00000004
: This op code is used to reduce one value from another. Operands are likely to be ignored as constant.
- 0x00000003
: This op code is used to invite the function. In this case, it is probably called thetx.origin ‘field, which contains information about the origin of the event.
insights and advice
When dealing with Nytandard TX: Eastern OP Codes, keep in mind:
- Always check the
scriptpubkey 'to understand what data is sent.
- To ensuretxhash` by checking its hexadecimal presentation or using an Eterscan -like tool.
- When working with events, it is necessary to understand roles and values.
By analyzing these examples and understanding OP codes, you are better equipped to combat more complex Ethereum events in your Python code. Good analysis!
