Ethereum: Looking for comprehensive documentation for Solidity-generated bytecode

Ethereum: Complete documentation for the housing code generated by Solidity

As a developer working with blockchain platforms based on Ethereum, it is necessary to have a solid understanding of the structure of the bait generated by the fortress. The aim of this documentation is to provide an exhausting guide with the identification and analysis of the various OPCode and the structures used in the Solidity Code.

Introduction

Solide is a university programming language used to write smart blockchaine ethereum contracts. When compiling the rigidity code in the Bytecode, the Ethereum (EVM) virtual machine (EVM) translates it into a native machine code that can be performed by the Ethereum network. Bajtecode is then performed by nodes or scripts operating in the network.

Understand Opcodes

In solidity, the Opcode is the instructions that are carried out during the compilation and implementation of the Intelligent Code. There are several types of opcodes, each of which serves a specific goal:

  • Load

    : Loads memory data in the variable.

  • Store : stores data in memory or storage slot.

  • BIP32 : Create a few elliptical keyboards of the Digital Signature Courbe (ECDSA) and store it on blockchain.

  • BIP44 : Create a private key to the pseudorand (PRF) function from the seminal sentence.

  • Call : You are calling another contract or function in the same address area.

Structures

Solide also uses several structures to represent data, especially at:

1

  • INT8 ,
    UINT8 ,
    INT16 A
    UINT16

    : Representation of full values ​​8 -bit.

  • String : Presents the Character Chain.

OPCODES common in Sotionity

Here is an overview of certain common opcodes found in Bytecode generated solidity:

  • 0x01 (Loading) : Loads a variable with a given memory name.

  • 0x02 (storage) : stores data in memory or storage slot.

  • 0x04 (BIP32) : Create an ECDSA private key and saves it on blockchain.

  • 0x05 (BIP44) : Create a private key PRF from the seed sentence.

  • 0x06 (call) : You call another contract or function in the same address area.

Analyze the fits generated using Solidity

During the analysis of the apartment generated by solidness, the following factors should be considered:

1

  • Switching of the context : Recognition when the context is switched (for example between contract calls or access to memory).

  • Data types : Identification of data types used in variables, such as Int8,uint8 etc.

Proven procedures

To make your analysis more efficient and more efficient:

1.

  • Implement the correspondence of models : Identify models in open and structures to simplify the analysis.

  • Consider the architecture of the contract : Understand how data is orbited between contracts to optimize analysis.

By following this guide, you will be able to fully understand the complexity of the bytecode generated by solidness and improve your analytical skills when you work with Ethereum Blockchain platforms.

Code Examples

Here are some examples of the code to illustrate key concepts:

  • “Address”: Pragma Solidity ^ 0.8,0; Public address myadress = 0x1234567890123456789012345678901234567890;

  • Int8and uint8:octet myint8 = 1; uint32 myuint8 = 256;

  • String: string mystring = “hello, world!”; “

Be sure to consult the official Solidey documentation, where you will find more information about the use of OPCODE and the structure of the structure. Good analysis!
