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.

A computerized platform enables secure, policy-compliant creation, governance, and monetization of digital artifacts produced by AI-driven “persona” agents in regulated domains (e.g., healthcare, finance). For each agent session, a federated compliance-token generator issues a cryptographically signed token embedding the full delegation chain, credential lineage, real-time policy snapshot, monetization rules, expiration and revocation data. As artifacts or workflows cross organizational or jurisdictional boundaries, a token inheritance module can subdivide, transfer, renew, or revoke the token while appending each event to an immutable, cryptographically linked audit trail. Every agent output is encapsulated as a digitally signed artifact that is indelibly linked to its originating compliance token and enriched with provenance, consent, and service metadata. A permissioned blockchain (or sharded distributed ledger) functions as an asset registry that immutably stores artifacts, tokens, and chronological records of creation, access, transfer, consent change, and policy updates. A smart-contract monetization engine allocates revenue or royalties based on artifact usage and institutional agreements, writing each billing event atomically to the ledger. Collectively, the system delivers continuous end-to-end traceability, privacy preservation, and automated financial settlement across diverse institutional boundaries.

Systems and methods are directed to optimizing a security and recoverability trade-off generally associated with cryptocurrency master key storage. Exemplary embodiments provide a biometrically derived cryptographic seed using a measurement of one or more scale invariant biometric attributes associated with a user. The measured user biometric data is then processed into a repeatable biometric identifier and formatted into a (biometric) cryptographic seed, for derivation of a master extended private key, which may be stored in an HD wallet or used dynamically to conduct a blockchain transaction. The biometric seed and master key generation process may be facilitated by a mobile application responsive to a readout of biometric data from sensors integrated/associated with the mobile device. The captured biometric data may be cryptographically combined with a user-inputted password and/or an authentication data record wirelessly retrieved from an OTP card, to generate a cryptographic seed with greater security attributes.
