Bit Cloud refers to a decentralized storage solution that utilizes blockchain technology to securely store and manage data. It allows users to store files across a network of computers, ensuring that data is not held in a single location, which enhances security and reliability. This technology is often associated with cryptocurrency and distributed ledger systems, as it leverages the same principles of decentralization and transparency. By using smart contracts, users can automate processes related to data storage and access, making it a flexible option for individuals and businesses looking to safeguard their information.
