The problem it solves
Current grading processes lack transparency and can lead to mistrust among collectors. This service aims to provide verified, traceable grading results.
How it makes money
Charge a fee for grading services, with additional fees for premium tracking features and historical data access on the blockchain.
Skills you need
Blockchain technology expertise, knowledge of card grading, software development, and regulatory compliance.
The market, and why this works now
Blockchain Grading leverages Ethereum's smart contracts to ensure transparent and verifiable grading processes for trading cards. A potential first-revenue move is to partner with the r/TradingCards subreddit, offering exclusive promotions to users who utilize the grading service. A key risk involves the initial capital required for software development and compliance with regulations surrounding digital asset tracking, which may strain resources during the early stages of the business.
