# Card Digitalization & Management

Tradible employs a secure system to ensure that each collectible card’s digital twin is seamlessly connected to its physical counterpart. Once a card is authenticated, a digital version is created and added to your Tradible collection, allowing for effortless management, trading, and tracking.

Our platform takes great care to ensure that each card’s digital representation remains synchronized with its physical version. This means that collectors can interact with their collections in a dynamic, real-time environment, enjoying the benefits of instant trading and transparent ownership. Whether you’re organizing your collection, making a trade, or reviewing its progress, every asset is securely managed on our platform, offering a reliable and enjoyable experience.

Tradible introduces a sophisticated Proof of Integrity system that guarantees each collectible card’s digital twin is verifiably linked to its physical counterpart. Our approach leverages the power of **Base's scalable and fast infrastructure** to ensure that every digital representation of a collectible card is secure, authentic, and tamper-proof.

**Asset Identity and Unique Fingerprints**

Every card stored in our vault is given a precise description along with a unique identification number. These identifiers help differentiate between similar items, especially when dealing with multiple copies of the same card. For graded cards that already have unique identifiers (such as PSA, Beckett, or others), these identifiers are used to form the fingerprint of the asset. For cards that don’t have pre-existing identifiers, Tradible assigns a unique ID and includes it in the image attached to the digital twin.

**Converting Fingerprints into a Proof of Integrity**

The fingerprint of an item, combining its unique ID and description, is encoded using a robust cryptographic function on **Base’s** infrastructure. This encoding process generates a unique digital string known as the Proof of Integrity, ensuring that every physical item remains connected to its digital twin.

Once the fingerprint is encoded, it is associated with the digital twin, guaranteeing that the information has not been altered. If the description or any part of the fingerprint is modified, the Proof of Integrity changes, making it clear that the item has been tampered with.

**How Proof of Integrity Ensures Tamper-Proof Collectibles**

The Proof of Integrity on Tradible guarantees the authenticity of the asset and prevents tampering with the information. The process includes the following elements:

• **Immutable Proof:** Once the Proof of Integrity is recorded in our system, it is final. No one can alter the data without it being detected.

• **Unique Fingerprint:** The unique fingerprint, linked directly to the physical card, is the only identifier that matches the Proof of Integrity, and no changes can be made to it without invalidating the link.

• **Security & Transparency:** The integrity of the card’s identity is ensured by using **Base’s** secure infrastructure, meaning that the digital twin of the card will always match the details of the physical card in our vault.
