Data Storage Solutions refer to the various methods and technologies employed to store data on public blockchains. Given the limitations of on-chain storage, such as scalability and cost, this feature encompasses both layer-2 solutions, which enhance blockchain capacity by processing transactions off the main chain, and off-chain alternatives that allow for the management of large datasets without congesting the blockchain. These solutions aim to provide efficient, secure, and cost-effective ways to handle data while maintaining the integrity and transparency of blockchain technology.
