Raze Network is a Substrate-based cross-chain privacy protocol for the Polkadot ecosystem. It is building a Cross-chain Privacy Middleware for DeFi and Web3.0. It is a native privacy layer that can provide end-to-end anonymity for the entire DeFi and Web3.0 stack. The objective is to enable cross-chain privacy-preserving payment and trading systems while protecting the transparency of your assets and behaviors from surveillance. Eventually, Raze Network can anonymize all the cryptocurrencies across all chains. RAZE is the native utility token that is used for: RAZE token plays the role of the core utility in the Raze Network ecosystem. It can capture the values included below but not limited to: Privacy-Preserving: RAZE gives DeFi users the ability to move between applications and blockchains seamlessly while leaving no trace of trading history or interactions with applications. Governance and Voting: RAZE token holders can create and vote for proposals Intermediary of Exchange: RAZE token can be used for different services in the ecosystem. Token Burning: A certain percentage of transaction fees are burned in the form of RAZE tokens. Liquidity Reward: The market makers providing liquidity in pools will be rewarded with RAZE token. RAZE technical architecture includes: Raze Network will apply the Zether framework to build the second-layer decentralized anonymous payment module. It will be then imported as substrate-based smart contracts. It will have three technical modules: Mint: The mint module will convert a base token into its anonymized version Transfer: The transfer module is the one that enables the anonymous transfer of the anonymized token Redeem: The redeem module will convert the anonymized token back to its native form. To sum up, Raze uses public-key homomorphic encryption to ensure transaction details remain confidential and uses the "one-out-of-many" proof to hide the sender and receiver identities, and some other zero-knowledge proof schemes are also used to guarantee the payment consistency.
