Ruby Protocol is a data monetization framework based on functional encryption, supported by Polkadot. It designs and implements a fine-grained data monetization framework as a privacy layer for interacting with smart contract platforms. It can realize end-to-end encrypted data monetization on public blockchains (such as Ethereum, Polkadot) and decentralized data solutions (such as IPFS).RUBY is the native token of the Ruby protocol, which will play the role of governance and utility. RUBY plays a crucial role in ensuring network decentralization. The uses of RUBY include but are not limited to:Layout: All nodes need to pledge RUBY to ensure decentralization of the Ruby protocol.Governance: RUBY token holders can create proposals and vote. Token holders can vote on protocol upgrades and parameter changes.Rewards: RUBY serves as a reward for those who apply data monetization and provide liquidity.
