Off-chain storage refers to the practice of storing data outside of a blockchain. While blockchains are primarily used for transaction records and smart contracts, they can become slow and costly when dealing with large amounts of data.In contrast, off-chain storage allows users to keep larger files, such as images, videos, or extensive records, in more scalable solutions like centralized servers, decentralized networks, or cloud storage services. This approach can enhance efficiency by reducing the burden on the blockchain, which can lead to faster transaction times and lower fees. After storing data off-chain, references or hashes of that data can be recorded on the blockchain to maintain integrity and ensure authenticity. By balancing the load between on-chain and off-chain solutions, users can enjoy the benefits of blockchain technology while mitigating its limitations, making it a practical choice for applications that require data-heavy operations.
