The present disclosure relates to systems (102) and methods for enabling privacy and transparency in electoral bonds using cryptography and blockchain. The cryptographic scheme is incorporated to enable donors privacy and citizens right to information in the electoral bond process. The proposed system (102) leverages cryptographic primitives such as zero-knowledge proof and homomorphic encryption simultaneously. The zero-knowledge proof enables verifiable computation which lets users perform computations privately and prove the validity of the same using zero-knowledge proof. The homomorphic encryption lets participants perform computations on encrypted data. System (102) leverages smart contracts to ensure the transparency of the functionality thereby further strengthening the trust in the system.

This invention pertains to the fields of distributed ledger, cryptocurrency, and decentralized physical infrastructure network. It solves the problems of the blockchain trilemma and cryptocurrency's lack of a real-world value that is recognizable to the mainstream population. Those two problems have prevented any cryptocurrency from gaining mass adoption. The Golf Ledger is distributed across a network of computers that are installed at up to 40,000 golf courses to leverage the existing decentralization of the world's golf courses and their ownership entry barrier and therefore does not need to sacrifice scalability for decentralization and security. The Golf Token as the native cryptocurrency of the Golf Ledger network is rewarded to golf courses for their contributing more and more computing resources to make the network more scalable. Their customers can use the Golf Token to pay golfing fees and get a discount, which is an obvious real-world value.

The present application discloses a data processing method, which is applied to a blockchain management system. The system comprises a first client, a second client, and a blockchain network, and a first smart contract is deployed on a plurality of chain nodes in a network. The method comprises: a first client uses a fully homomorphic public key issued by a sub-key group to encrypt first data, and then sends transaction information to a chain node, wherein the transaction information comprises a ciphertext of the first data; the chain node records the ciphertext of the first data in a blockchain ledger, and declares, by means of the first smart contract, that a data type of the ciphertext of the first data is a fully homomorphic ciphertext; and a second client sends an operation request to the chain node. The chain node performs a fully homomorphic operation on the ciphertext of the first data on the basis of the first smart contract and a fully homomorphic evaluation key issued by the sub-key group, and records the homomorphic operation result in the blockchain ledger. Thus, the security of data having high security requirements is guaranteed on the premise of not sacrificing the availability and operability of on-chain data.
