Proposal of a Service Model for Blockchain-Based Security Tokens

·

Blockchain technology has revolutionized the way we think about ownership, investment, and asset management. One of the most promising applications of this innovation is the concept of security tokens—digital representations of real-world assets that are issued, managed, and traded on blockchain networks. Unlike traditional cryptocurrencies such as Bitcoin or Ethereum, security tokens are backed by tangible or intangible assets like real estate, art, intellectual property, or even future revenue streams. This article explores a comprehensive service model for blockchain-based security tokens, outlining its structure, key stakeholders, operational workflows, and essential security requirements.

The global market for tokenized assets is projected to reach $10 trillion by 2030, signaling a massive shift toward decentralized, transparent, and accessible financial systems. To support this transformation, a robust and secure service model is essential—one that ensures regulatory compliance, protects user privacy, prevents fraud, and promotes widespread adoption.


Understanding Security Tokens and Asset Tokenization

Asset tokenization refers to the process of digitally representing ownership of an asset by breaking it into smaller, tradable units on a blockchain. Each unit, known as a security token, represents a share in the underlying asset's value and confers rights such as profit-sharing, voting, or redemption.

This model enables fractional ownership, meaning investors can purchase small portions of high-value assets—such as a $1 million building—with as little as $10. This democratizes access to alternative investments previously limited to institutional players or high-net-worth individuals.

Key Stakeholders in the Security Token Ecosystem

The proposed service model involves several interconnected roles, each critical to ensuring the integrity, functionality, and security of the system:

Each stakeholder plays a vital role in maintaining trust and efficiency across the ecosystem.


The Lifecycle of a Security Token

Unlike utility tokens or cryptocurrencies, security tokens follow a structured lifecycle that includes five distinct phases:

  1. Issuance: The issuer creates tokens based on asset value and distributes them to investors via blockchain transactions.
  2. Distribution: Tokens are allocated proportionally to investors who have contributed funds through the TSP.
  3. Usage/Trading: Holders can trade tokens on exchanges or transfer them directly on-chain.
  4. Storage: Tokens may be held long-term in personal wallets or entrusted to custodians.
  5. Revocation: Once the asset’s lifecycle ends (e.g., property sold or project completed), tokens are permanently retired by transferring them to a designated revocation wallet.

This revocation phase is unique to security tokens and ensures no residual claims exist after asset fulfillment.


How Investment in Tokenized Assets Works

Let’s walk through a practical scenario:

  1. An asset owner registers a property valued at $100,000 with a TSP.
  2. The TSP divides the asset into 1,000 security tokens priced at $100 each.
  3. An investor purchases one token ($100), gaining 0.1% ownership.
  4. The TSP instructs the issuer to mint the token on-chain.
  5. Upon successful issuance verified via blockchain data, the TSP pays the asset owner.
  6. If the property generates rental income or is later sold at a profit, dividends are distributed proportionally to token holders.

This process enables micro-investing while maintaining legal and financial accountability.


Trading Security Tokens: Interoperability and Compliance

Security token exchanges must support multiple transaction types:

To ensure regulatory compliance:

Interoperability between exchanges—even those without native security token wallets—enables broader market access and deeper liquidity pools.

Addressing Security Threats in the Model

While the benefits are substantial, several risks must be mitigated:

Common Security Threats


Essential Security Requirements

To counter these threats, the following safeguards are recommended:

1. Separation Between Issuer and TSP

Ensures independent verification of issuance and revocation volumes—preventing over-issuance or incomplete revocations.

2. Separation Between Issuer and Exchange

Allows exchanges to audit token supply independently, reducing risk of market manipulation.

3. Wallet Segregation & Audit Logs

Custodians must maintain separate wallets per holder and log all transfers with digital signatures for non-repudiation.

4. Data Encryption

Use AES-128, SHA-256, and TLS protocols to encrypt stored and transmitted PII in TSPs and exchanges.

5. Decentralized Identity (DID)

Enable users to authenticate using self-sovereign identities without exposing sensitive data—reducing exposure points for PII breaches.

6. Investment Protection Mechanisms

TSPs should verify asset valuations via third-party appraisals and hold investor funds in segregated accounts with regulated financial institutions.


Frequently Asked Questions (FAQ)

Q: What makes security tokens different from regular cryptocurrencies?
A: Security tokens represent ownership in real-world assets and are subject to securities regulations, unlike decentralized cryptocurrencies like Bitcoin which function more as digital cash or speculative assets.

Q: Can anyone invest in tokenized assets?
A: Yes—fractional ownership allows small investments (as low as $5–$10), making high-value assets accessible to retail investors globally.

Q: How are profits distributed to token holders?
A: Profits from asset management (e.g., rent, sales proceeds) are distributed proportionally based on token holdings, typically through smart contracts.

Q: Are security tokens reversible once revoked?
A: No—once revoked (e.g., after asset sale), tokens are sent to an unspendable address and cannot be reissued or transferred again.

Q: Is blockchain necessary for this model?
A: Absolutely. Blockchain provides immutable record-keeping, transparency, traceability, and automation through smart contracts—critical for trust and scalability.

Q: How do regulators monitor security token activity?
A: Regulators can run nodes on permissioned blockchains to view issuance/revocation logs and receive audited trade reports from exchanges in real time.

Future Outlook and Standardization Efforts

The proposed service model is being considered for standardization under ISO/TC 307, focusing on blockchain and distributed ledger technologies. Additionally, South Korea’s Telecommunications Technology Association (TTA PG502) is developing localized security guidelines.

As technology evolves, further enhancements will focus on:

Private enterprises will eventually adopt this framework through technology licensing, paving the way for a new era of inclusive, efficient, and secure digital asset markets.

By combining innovation with strong governance, blockchain-based security tokens have the potential to redefine global finance—one tokenized asset at a time.
