Buying and selling blockchain-based goods with traditional currencies

Buying and selling blockchain-based goods with traditional currencies

Glossary of important terms

Blockchain: A decentralized, immutable ledger of transactions recorded in chronological order in “blocks”, with each block cryptographically linked to the previous block.

Cryptocurrency: A digital or virtual currency that uses cryptography to secure transactions and control the creation of additional currency units. Bitcoin and Ethereum are examples of cryptocurrencies.

Smart contract: A piece of code stored on a blockchain that automatically performs actions when predefined conditions are met. Smart contracts can be used to automate agreements to buy and sell goods or services.

Fiat currency: A legal currency issued by a government, such as the dollar, euro, or yen.

Crypto exchange: A platform where users can buy and sell cryptocurrencies.

Blockchain wallet: A digital wallet used to store cryptocurrencies.

Blockchain-based goods: Digital assets stored on a blockchain that can be bought and sold with cryptocurrency.

Pre-purchase: Purchasing a good or service before a purchase request is received.

Escrow: A service that holds an asset on behalf of another person.

Trust period: A period of time that must pass before a user is allowed to access or withdraw an asset.

Minting: Creating a new blockchain-based good on a blockchain.

Main Concepts

Challenges: Traditionally, purchasing blockchain-based goods requires users to set up a cryptocurrency wallet and use a cryptocurrency exchange, which is complex for the average user.

Solution: The patent proposes a system that enables users to purchase blockchain-based goods with fiat currency using traditional payment methods such as credit or debit cards without directly interacting with cryptocurrencies.

Process:

Sellers list blockchain-based goods on a blockchain smart contract platform.

Buyers select a product and pay with fiat currency.

The system funds the buyer's purchase using pre-purchased cryptocurrency reserves or real-time purchases of cryptocurrency through an exchange.

Smart contract execution transfers ownership of the goods to the buyer.

If the buyer does not have a cryptocurrency wallet, the system can provide a temporary wallet or escrow the item.

Benefits:

Simplifies the blockchain-based goods purchase process for the average user.

Promotes the adoption of blockchain-based goods by providing familiar payment methods.

Eliminates the need for buyers to set up cryptocurrency wallets by providing temporary wallets or escrow services.

Other Features:

The system can support auctions and fixed-price goods.

Sellers can choose to receive payment in cryptocurrency or fiat currency.

The system can maintain independent cryptocurrency reserves based on buyer and seller characteristics.

Answer

The traditional purchase process requires users to set up a cryptocurrency wallet and create an account on a cryptocurrency exchange, which is complicated and time-consuming for the average user.

This system eliminates the need for these steps by allowing users to pay with fiat currency using traditional payment methods such as credit or debit cards. The system handles all necessary cryptocurrency transactions on behalf of the user.

The system converts the fiat currency payments received into the corresponding cryptocurrency amount, which is used to execute the purchase of goods through smart contracts.

The cryptocurrency reserve system is a pool of cryptocurrency held by the system to fund purchases made using fiat currency. This ensures fast transactions because the system does not have to purchase cryptocurrency from an exchange for every purchase.

The system can generate a temporary wallet for the buyer or hold the item in escrow on the buyer's behalf until they choose to transfer it to their own wallet.

Sellers can choose to receive payment in cryptocurrency (such as Ethereum) or fiat currency, which provides them with flexibility.

The system is often faster than the traditional purchase process because it streamlines the payment process and eliminates delays by using cryptocurrency reserves or purchasing in real time through exchanges.

Pre-purchasing refers to the system purchasing blockchain-based items before receiving a purchase request. This ensures the availability of the item and allows for faster delivery of the item to the buyer.

The system builds trust between buyers and sellers by handling all necessary cryptocurrency transactions and utilizing smart contracts to ensure transparent and secure transfer of ownership of the item.

The advantages of the system include increased convenience, faster transaction speeds, and wider adoption. However, potential disadvantages include the system's reliance on centralized entities to manage cryptocurrency reserves and potential fees associated with fiat and cryptocurrency transactions.
