Understanding Tokenization

What is Tokenization?

Tokenization is the process of converting real-world assets like real estate, commodities, and intellectual properties into digital tokens on a blockchain. These tradable tokens represent ownership rights. This transformation enables fractional ownership, i.e. high-value assets can be divided into smaller and more affordable portions.

Benefits of Tokenization

  • Liquidity
    Tokenization improves liquidity by facilitating the trading of traditionally illiquid assets. Investors can now get their invested funds without waiting for lengthy settlement processes.
  • Fractional Ownership
    It makes investing more accessible and inclusive by enabling individuals to own a fraction of high-value assets.
  • Transparency
    Blockchain technology offers a transparent, immutable ledger that ensures the accuracy of ownership records.
  • Efficiency
    Tokenized assets can be exchanged 24/7, removing the need for intermediaries and speeding up transactions.

The Need for Compliance in Tokenization

Tokenization, no doubt, has gained important traction, however, it also presents a range of challenges.

Regulatory Challenges

  • Legal Frameworks
    Existing regulatory frameworks often struggle to adapt to the unique nature of tokenized assets. To ensure legal compliance, clear guidelines are essential.
  • Investor Protection
    Without adequate safeguards, investors risk falling into shady scams. To defend their interests, compliance measures are essential.
  • Market Integrity
    For long-term success in tokenized markets, maintaining trust and integrity is essential. An essential component of market integrity is regulatory compliance.

The Importance of Compliance

Compliance acts as a protective shield in the tokenization ecosystem. This will guarantee that tokenized assets adhere to applicable laws/regulations to safeguard the interests of investors and market participants. 

Compliance is an essential component of trust and is more than just a legal obligation. Investors need assurance that the environment in which their investments are made is safe and regulated. This trust forms the bedrock upon which the tokenization ecosystem can thrive.

ERC3643 stands out as a crucial standard that tackles compliance challenges head-on. It provides issuers with a framework for minting and managing identity-based permissions tokens, ensuring that only authorized users possess these tokens.

ERC3643 in a Nutshell

ERC3643 is a suite of smart contracts and not a single contract created to facilitate compliance tokenization. Further, these contracts create the backbone of identity-based permissions tokens by adding a layer of security and trust to the tokenization process.

What is ERC3648??

Previously known as the T-REX protocol, ERC-3643 protocol is an open-source suite of smart contracts enabling the issuance, management, and transfer of permissioned tokens.

The primary goal of ERC3643 is to facilitate compliance through the issuing of permissioned tokens based on identity. These tokens have a unique twist that only users who meet certain eligibility criteria are permitted to hold tokens. This eligibility is determined by verifying the digital identities of users, ensuring that compliance is embedded into the token itself.

The purpose of ERC3643 is to close the gap between the innovative potential of tokenization and the requirement for strict regulatory compliance.

The Components of ERC3643

There are several key components that work together to strengthen ERC3643. They are


ONCHAINID is a decentralized system acting as the foundation of ERC3643. Using ONCHAINID, users can create their self-sovereign identities on the blockchain. Most importantly, private data remains off-chain with trusted parties, preserving confidentiality. Identity proofs, in the form of data validations, are securely published on the blockchain, providing a trustworthy record of user identities.

ONCHAINID works by allowing users to establish their self-sovereign identities using blockchain technology. This protocol securely stores private data off-chain with trusted entities rather than storing it on the blockchain. Blockchain technology is used to record encrypted identity proofs that deliver a transparent validation of data authenticity.

Decentralized Identity System

This component stores the addresses of all trusted claim issuers associated with a specific token. These claim issuers are crucial in verifying user identities while also making sure that only eligible individuals hold the token.

Being a decentralized repository, Trusted Issuers Registry (TIR) is designed to store details pertaining to trusted issuers, including public information and accreditations. All data is compressed in the form of Verifiable Accreditations within the Trusted Issuers Registry. 

  • Claim Topics Registry
    A complete list of trusted claim topics related to the security token is kept up to date by the Claim Topics Registry. These claim topics outline the precise attributes and information that must be verified for compliance. It helps to create transparent methods for validating claims and improving accuracy across a range of applications, including academic achievements, professional certifications, etc. within the blockchain ecosystem.
  • Identity Registry
    All eligible users who are authorized to hold the token are listed in the Identity Registry. It serves as a single repository of identity contract addresses. Its primary function is to confirm user claims and make sure they adhere to the requirements for token ownership. Users store their identification credentials and data within a decentralized identity wallet application, and blockchain technology enables hassle-free verification without communicating with the credential issuer.

How ERC3643 Tokens Works

With the creation of tokens, ERC3643 sets out on its voyage. The components of the suite are used by asset issuers to mint identity-based permissioned tokens. These tokens represent a unique asset like real estate, goods, intellectual property and more. These tokens are intended to enforce compliance from the moment they are created, making sure that only eligible individuals are able to hold and transfer them.

How ERC3643 Works

The ONCHAINID component is an essential part of ERC3643. An investor’s digital identity is meticulously verified using ONCHAINID when they want to purchase these tokens. This decentralized identity system plays the role of a gatekeeper, ensuring that investors meet the eligibility criteria established for the token. To determine whether the investor is authorised to hold the specific asset-backed token, this verification is important.

ERC3643’s ability to enforce compliance at the level of smart contracts is one of its main strengths. The Compliance Smart Contract, operating independently, becomes the final arbiter when it comes to validating token transfer requests. It verifies that each transfer complies with the token’s set conditions and rules. This entails confirming the investor’s eligibility (through ONCHAINID) as well as the specific offering rules set for the token.

Practically, ERC3643 automates the compliance procedure, which is essential for providing safe and reliable transactions within the tokenized asset ecosystem. ERC3643 considerably reduces the risk of fraudulent activity by enforcing compliance at the smart contract level and ensures that only authorised investors can take part in the token economy.

Overall, ERC3643 stands out as a strong standard for asset tokenization because of its thorough and automated approach to compliance, providing a secure and effective way to handle and trade tokenized assets while maintaining regulatory compliance. This level of complexity in compliance is essential in building trust and confidence in the rapidly evolving world of blockchain-based finance and asset management.
