Japanese blockchain developer Chainbow has recently launched a second layer protocol based on BSV. It is reported that Chainbow was established in 2018 and is committed to developing blockchain products, including digital currency wallets, payment services, and O2O platforms. NOTE The private information protocol supports CRUD (that is, create, read, and delete data and user permissions) to manage information on the blockchain. The platform also promotes data encryption and decryption as well as data sharing rules, permission verification, and data storage history records rules. In addition to the agreement, Chainbow also launched NoteSV, the first application built specifically for the platform, similar to existing password management tools such as Lastpass and 1Password. The technology includes password generation, password security, and two-step authentication.
