0000 The present technology can provide decentralized security and data management using a decentralized system to generate a cryptography key for decrypting data and using a smart contract to determine access to the cryptography key. The system obtains a request associated with a cryptography key (e.g., a request to decrypt data), and the request indicates the user's identity, a smart contract, and the identity of the key. The system checks a smart contract on a blockchain to determine whether the access conditions are satisfied for the smart contract. When access is authorized, the system generates a derived, cryptography key using a threshold of independent parties (e.g., key servers and/or members of a multi-party computation (MPC) committee). Threshold cryptography can be used in which t-out-of-n independent parties are required to generate the derived key.

0000 A system and method for autonomous smart-contract-enforced dual-ledger state management of blockchain-based digital instruments. A smart contract module deployed on a permissioned blockchain network mints digital instruments each comprising on-chain metadata encoding an instrument-type identifier, a jurisdiction identifier, a maturity-condition set, a transaction-cycle counter, and a redemption-state flag. A dual-account ledger enforced by smart contract state variables maintains a first sub-ledger for active instrument circulation and a second sub-ledger for independent accumulation of transaction-derived value, wherein the segregation between sub-ledgers prevents accrual obligations from depleting active circulation liquidity at the protocol layer without human administrative intervention. A geofencing enforcement module validates each proposed transfer against permitted geographic jurisdictions using cross-source consistency analysis of a plurality of location-related inputs and prevents blockchain confirmation of transfers that fail jurisdictional validation. A transaction-processing module increments an on-chain cycle counter upon each qualifying transfer and allocates transaction-derived value to the second sub-ledger. Upon autonomous determination that all encoded maturity conditions are satisfied, the smart contract executes an atomic burn-to-unlock operation comprising token destruction, redemption-state flag transition, and second-sub-ledger balance release

A blockchain-based digital token system enables state governments to transform government-issued fiscal incentives into geo-fenced, multi-cycle digital tokens. Each token is minted on a permissioned blockchain, pegged at a one-to-one ratio to a fiat currency, and backed by a state-managed reserve account. Tokens are issued in a non-redeemable state and must complete a configurable number of validated transactions within an authorized geographic boundary before becoming eligible for redemption. A geo-fencing module performs two-point authentication for each transaction by verifying merchant identity against a registry and comparing cryptographically signed location data against permissible geographic regions. A smart contract engine increments a usage counter for each validated transaction and updates the token to a redeemable state upon meeting the threshold. Users interact through a dual-compartment digital wallet displaying non-redeemable and redeemable tokens separately. Upon redemption, tokens are permanently burned to maintain supply alignment with the fiat reserve.

The present application relates to a computing power asset management method, a computing power asset management apparatus, and a computer device. An on‑chain terminal can perform computing power measurement on the basis of a computing power asset provided by a computing power asset supplier, so as to determine a corresponding measurement result, and generate a corresponding asset identifier on the basis of the measurement result. When on‑chain data comprising the measurement result and the asset identifier is stored on a chain, an asset permission query instruction is sent to a blockchain network node, so that the blockchain network node polls a transaction state. When it is polled that there is on‑chain data of which the transaction has been completed, the blockchain node sends authorization information and a deployment instruction of a computing power purchaser of the on‑chain data to the on‑chain terminal. The on‑chain terminal can receive the authorization information and the deployment instruction issued by the blockchain network node, and in response to the deployment instruction, deploy the authorization information to the corresponding computing power asset, so that the computing power purchaser can log in and use the computing power asset on the basis of the authorization information.

Data backups are performed in multiple blockchain environments. Digital pictures, movies, computer files, apps, and any other electronic data may be automatically backed-up, or duplicated, to multiple blockchain networks. First, an electronic data is written to a first blockchain network. A second, different, blockchain network is automatically selected based on many factors and/or parameters. Then, the electronic data is written to the second blockchain network. Still more duplicate copies of the electronic data may be redundantly written to third, fourth, and more blockchain networks. Any of the blockchain networks may send a confirmation that confirms the duplicate copy was written. One or more cryptographic proofs may be generated to prove the duplicate copies were stored to the multiple blockchain networks.
