Blockchain storage is a way of saving data in a decentralized network which utilizes the unused hard disk space of users across the world to store files. BitTorrent (Token: BTT), a decentralized file-sharing protocol; Arweave (Token: AR), a new type of storage that backs data with sustainable and perpetual endowments; Crust Network (Token: CRU), a decentralized storage network that supports multiple storage layer protocols; Siacoin (Token: SC), a decentralized storage solution for the post-cloud world; Storj (Token: STORJ), a decentralized cloud storage platform for node operators and developers; Bluzelle (Token: BNT), a dPoS decentralized database that enables dapps to store data; Lambda (Token: LAMB), a secure, reliable, and scalable decentralized storage network. These projects are alternatives to centralized cloud storage and can solve many problems such as data privacy, security and manipulation. Their tokens are also performing well in the crypto market recently.
