The invention relates to distributed ledge technologies such as consensus-based blockchains. Computer-implemented methods for a secure random number generation within blockchain scripts are described. The invention is implemented using a blockchain network, which may be, for example, a Bitcoin blockchain. A first transaction that includes a puzzle is validated at a node in a blockchain network, with the first transaction being associated with a digital asset, and with a solution to the puzzle being indeterminable at a time of validation of the first transaction. A pseudorandom number, based at least in part on a solution to the puzzle that is included in a second transaction, is generated at least in part by validating the second transaction, the second transaction created to transfer control of the digital asset associated with the first transaction. Control of the digital asset is transferred based at least in part on the pseudorandom number.

0000 A secure cryptocurrency system comprising a tamper-resistant hardware device that generates dynamic passwords at predetermined time intervals while maintaining encrypted storage of authentication credentials. The device integrates multiple biometric sensors including fingerprint, retinal scan, and heartbeat pattern recognition to provide multi-modal authentication that eliminates static password vulnerabilities. The system stores devices in secure vault facilities at financial institutions with controlled access, creating “multiple redundancies across different locations” for continuity. A biometric fusion processor generates unified authentication decisions based on user-configurable security thresholds, implementing “tiered security” that varies access permissions based on cryptocurrency transaction amounts. The device includes fail-safe mechanisms that automatically disable upon tampering detection. Dynamic passwords display temporarily before automatically hiding, enabling “checking account functionality” through banking infrastructure integration while maintaining offline security.

Systems and methods of processing a payment. A server receives a collect request with a virtual account number and payment value from a merchant. The server uses the virtual account number to locate a certified master public key via a blockchain mapping. It sends a payment authorization request to the user's mobile app, receives an authorization, and processes the transaction on the blockchain using a token tied to fiat currency. Upon completion, the server notifies the merchant and initiates settlement between the user's issuer bank and the merchant's acquirer bank, converting between fiat and the in-network token as needed.

A management server checks an update command of a blockchain at each predetermined time (100 to 106), and in a case where the update command is checked when the predetermined time elapses, generates a transaction based on the update command (108, 112) and adds the transaction to the blockchain (114). On the other hand, in a case where the update command is not checked even after the predetermined time elapses, the management server generates a dummy transaction (108, 110), and performs a process of adding the generated dummy transaction to the blockchain (114).

An autonomous distributed wise area network (AD-WAN) includes several nodes, where each node connects a local area network to an open wide area network, and provides tunnels over the open wide area network to other nodes in the AD-WAN so that computing resources behind each node can communicate as if they were located on a common intranet. Each node has a blockchain wallet and receives updates to a private permissioned blockchain ledger for that AD-WAN. The updates are provided by a control node. Set up, and subsequent change to the AD-WAN are commenced via a customer portal which provides order information to the control node, where the control node processes the order information and generates a blockchain update that informs the affected nodes in the AD-WAN as to what changes are to be made.
