Our off-chain storage exists because non-transaction data, with personal information, shouldn’t be stored in blockchain technology.
A few of the obvious advantages of storing pictures, contracts, PDFs, and documents are:
• It’s faster. The transactions are recorded instantly, without having to wait for the network confirmations.
• It’s cheaper. Transactions done off-chain are less expensive.
• It’s more private. These transfers are not visible on the public blockchain.
