Blue provides a series of digital currency tools based on the Ethereum network, such as developer tools, client software and user guides. Through components such as the Blue Protocol, Blue SDK, Blue Wallet, and Blue Standard, protect user funds, improve user experience, ensure the security of digital assets, and help the Ethereum network and cryptocurrencies in general thrive.
By holding a certain number of Blue tokens determined by the platform in real time, any Ethereum wallet can access Blue protocol functions completely free of charge. This applies to the Blue wallet, any wallet that uses the Blue SDK, transactions that use the Blue SDK, and any supported Dapp. The Blue token system contains a cryptographic signature and associated metadata modified by the nonce, so that changes to the threat definition are unlikely to attack the security model of the token.
