Digital Twin Token

Introduction

The Digital Twin Token (DTT®) is the cornerstone of Magma's platform, representing a unique digital asset for each building. It serves as a unified reference point and a single source of truth for all stakeholders involved in the building’s lifecycle. By leveraging blockchain technology, the DTT® ensures that every piece of information attached to it is secure, traceable, and immutable. The DTT® is designed to address the challenges of property assessment, information asymmetry, sustainability, and illiquidity that plague the real estate industry.

Characterisitcs

The DTT® is a dynamic non-fungible token (NFT) minted on the blockchain, ensuring that each building has a unique digital identity. The NFT nature of the DTT® means it is a singular, non-replicable token that stores valuable metadata about the building. The token includes key architectural, structural, contractual, and financial data.

Moreover, the DTT® can store continuously updated information about the building, such as maintenance logs, insurance documents, and other relevant materials. By using EVM blockchains, the DTT® benefits from a robust and scalable infrastructure, that is efficient in energy use.

Token Standard

The Digital Twin Token (DTT®) is built using the ERC-1155 token standard, a multi-token standard that enables both fungible and non-fungible tokens to coexist within a single smart contract. This choice of standard allows for a flexible and efficient approach to managing the unique digital identity of each building and theirs components.

How it Works

Every contribution to the DTT® follows a controlled verification flow to guarantee data integrity, traceability, and correct anchoring to the token:

1. Upload & Hashing

When a stakeholder uploads a document, metadata, or any data entry, it is immediately hashed by the platform. This hash provides an immutable fingerprint of the information from the moment of upload.

2. Review & Validation

Assigned validators are notified and review the submission. They can validate the data or reject it with a mandatory explanation.

3. Minting & Attachment to the DTT®

After the data has been validated, the Owner or Asset Manager must mint (meaning update) the DTT® to attach the hashes. The data's hash is not part of the DTT® until this minting step is completed.

• Only after minting does the validated file become cryptographically anchored to the DTT®.

• Any subsequent change requires a new upload (producing a new hash), revalidation, and another mint/update to attach the new hash.

This workflow ensures: the platform captures an immutable fingerprint at upload; only validated items are eligible to be anchored; and the Owner/Asset Manager controls when validated data is cryptographically attached to the building’s DTT®.
