data storage options database and blockchain are architecturally different and come with their own sets of advantages, vulnerabilities, and challenges. data storage is based on client-server-based architecture and can function in small and large scale environments.

blockchain storage is decentralized storage based on a peer-to-peer network of a distributed ledger. each block stores the hashed information from the previous block, secured by cryptographic security. data is stored in uniform-sized blocks that can be traced back to the first block.

blockchain has no controlling infrastructure and is completely decentralized. it is composed of unbreakable rules and laws which don’t require regulation. data breaches are grave- they can cause damage to intellectual property and make clients lose trust in an organization. in the blockchain, trust in the network is the only factor in transaction and data storage.

blockchain and databases are susceptible to data theft and have vulnerabilities. public and private blockchains run the risk of 51 percent attack by a group of miners who control more than 50 percent of the hashing rate of the network. data backups are threatened by malware, but they become more vulnerable to attacks when data volume becomes large enough to be scalable.
