Questions & Answers

A blockchain is a decentralized digital ledger of transactions that is used to record data in a secure and tamper-proof manner. A blockchain consists of a series of “blocks,” which contain a list of transactions. Each block is linked to the previous one, creating a chain of blocks that cannot be altered without changing the entire chain. This means that once a transaction is recorded on the blockchain, it cannot be deleted or altered. Furthermore, entries are distributed among many different users and computers, with each user maintaining a copy of the ledger.

These aspects make the blockchain a powerful tool for recording and verifying data in a secure, trustworthy, and transparent way.

Crypto stamps use this technology to make their stamps tamper proof by linking the physical stamp with a digital token in the blockchain and therefore transferring the security aspects onto the physical product. To achieve this linkage between physical and digital components NFC technology and QR codes are used.

Near Field Communication (NFC) is a wireless technology standard that enables communication between two devices that are within close proximity of each other. The NFC technology opens up new possibilities for secure and easy verification of physical assets, such as collectables, artworks, and documents, in a world where the risk of counterfeiting is increasing.

With the crypto stamp, we’ve embedded encrypted NFC microchip that lets you verify the authenticity of your crypto stamp, by sending one-time messages that alters with each scan.

To use this NFC feature, simply activate the NFC function on your smartphone and hold your crypto stamp close to your device. Your smartphone will detect the NFC chip and will show you if the stamp is genuine.

An NFT, or non-fungible token, is a unique digital asset that represents ownership or proof of authenticity of a specific item, such as artwork, music, videos, or even stamps. Each NFT is unique and cannot be replicated. The ownership and transaction history of NFTs are recorded on a blockchain, providing a transparent and secure method of verifying their authenticity and ownership.

A crypto stamp is a physical stamp that is connected to a digital twin that is stored in the blockchain. This linkage provides complete traceability of all previous owners of the stamp, states its current ownership, makes it easily tradeable and proves its authenticity and uniqueness to ensure that buyers are getting genuine items.

Technically, the Guernsey Crypto Stamps are executed as blockchain tokens in the ERC721 standard, which is widely supported by many blockchain applications.

The Guernsey Crypto Stamps use the Polygon protocol, which was created to counteract issues with scalability and high transaction fees of other blockchain protocols. Polygon is often referred to as a “Layer-2 solution” because it operates on a separate blockchain network that is built on top of the Ethereum main chain. The Polygon network is designed to handle a large volume of transactions while maintaining low fees, while benefiting of Ethereum’s security and decentralization. This makes Polygon compatible with various NFT platforms such as OpenSea. Polygon utilizes the Proof-of-Stake consensus mechanism, which, in contrast to Proof-of-Work blockchains such as Bitcoin, is more environmentally friendly due to its lower energy consumption and reduced electronic waste production. Because of these sustainability and efficiency benefits, Guernsey Crypto Stamps use the Polygon network.

Both the digital part and the physical product were produced in Austria by the brand Stampfinity. Stampfinity is led by a printing company that specialises in special stamps such as crypto stamp. Further, Stampfinity developed all digital content and blockchain integrations for this project.

The total circulation of the first Guernsey Crypto Stamps are 15,000 stamps. This edition includes two variations “Nanny Goat” and “Billy Goat” with 7,500 stamps each.

To activate the NFT, simply scan the QR code on the back of the card with your mobile phone camera.

To transfer the NFT to another wallet, open the security label on the back of the crypto stamp. Scan the stamp using the NFC function or QR code, and then click on the “Transfer Info” button. Please scan the QR code below the label or type in the code [2] manually. Then enter the address of the wallet to which you want to transfer your NFT and confirm the transfer.

Metamask or Exodus are popular software wallets commonly used for managing Ethereum-based assets, including various ERC-20 tokens and decentralized applications (DApps).

Here’s a step-by-step guide on how to get a blockchain wallet using Metamask:

Install the Metamask Extension:

Visit the official Metamask website or go to the browser extension store (Chrome, Firefox, or Brave).

Download and install the Metamask extension for your preferred browser.

Set Up Your Wallet:

Click on the Metamask icon in your browser’s toolbar.

Follow the on-screen instructions to create a new wallet.

Generate and securely store a backup phrase (also known as a seed phrase). This phrase is crucial for recovering your wallet if you forget your password or lose access.

You can verify the authenticity of the stamp using the NFC scan function on your mobile phone. Activate the NFC-function in the settings of your Smartphone. Then hold it close to the stamp to scan it and open the pop-up message that appears.

Each NFT has a unique rarity, which is based on the attributes of the NFT. Each attribute has a rarity value. The rarity rating of the NFT is the combination of the rarity value of all its attributes.
