Objectives and Topics

The primary objective of this thesis is to assess the technical feasibility of utilizing blockchain technology—specifically smart contracts on the Ethereum platform—to facilitate the issuance and trading of corporate bonds without the need for traditional intermediaries. The study explores how core bond mechanisms can be mapped onto programmable smart contracts while adhering to established token standards.

• Blockchain technology integration in financial markets
• Technical design of smart contracts for fixed-interest corporate bonds
• Implementation of the ERC20 standard for security tokens
• Development and testing in the Remix Integrated Development Environment (IDE)
• Simulation of bond issuance, coupon payments, and secondary market trading

Excerpt from the Book

Summary of Chapters

1 Introduction: Provides an overview of the disruptive potential of blockchain in finance and outlines the motivation for developing a bond-focused smart contract.

2 Smart Contracts: Explores the conceptual foundations of smart contracts, the Solidity language, and the importance of the ERC20 token standard.

3 Corporate Bonds: Details the economic mechanics of fixed-interest corporate bonds and the mathematical logic behind valuation and cash flow.

4 Requirements for the Smart Contract: Defines the specific technical requirements for the contract, including issuance parameters and transaction types.

5 Remix: Introduces the Remix IDE as the development environment and explains its primary features for compiling and testing contracts.

6 The Bond Token Smart Contract: Presents the source code and functionality of the contract, explaining how data is stored and how logic is executed.

7 Simulations: Documents two practical scenarios testing the contract’s issuance and trade functionality to verify successful implementation.

8 Evaluation of the smart contract: Discusses the results of the simulations, identifies limitations in Solidity, and addresses future research needs regarding automation and regulation.

Frequently Asked Questions

What is the fundamental focus of this thesis?

This thesis investigates the technical realization of issuing and trading corporate bonds on the Ethereum blockchain, aiming to remove the reliance on central intermediaries.

What are the primary themes discussed?

The work covers blockchain fundamentals, smart contract programming in Solidity, financial modeling of corporate bonds, and the application of standardized token frameworks (ERC20).

What is the core research goal?

The goal is to determine the feasibility of creating a functioning smart contract that handles bond lifecycle events, such as issuance, coupon payment, and redemption.

Which scientific methods are employed?

The author uses a constructive development approach, programming the contract in Solidity and validating its functionality through simulated scenarios in the Remix IDE.

What topics are covered in the main section?

The main part encompasses the theoretical grounding, technical requirement analysis, code documentation, and the execution of simulations to verify the contract's logic.

Which keywords define this work?

Core keywords include Blockchain, Ethereum, Smart Contracts, Corporate Bonds, ERC20, and Tokenization.

How does the contract handle bond coupon payments?

The contract includes specific functions that allow the issuer to transfer coupon interests to investor accounts based on their registered token holdings.

What is the significance of the "Simulation two" chapter?

Simulation two focuses on secondary market trading, verifying that the smart contract can handle the transfer of bond tokens between two investors and manage compensation adjustments.

What does the author identify as a major limitation of Solidity?

The author highlights the lack of native support for fixed-point decimals, which makes high-precision financial calculations complex and potentially error-prone without specific workarounds.

Are legal implications included in the study?

No, the thesis focuses strictly on the technical implementation of the smart contract; legal and regulatory requirements for offering such financial products were excluded.
