An initial transaction is generated representing a forecasted demand for material needed to manufacture equipment via a supply chain. The initial transaction is added to a blockchain for access by entities in the supply chain comprising at least a subset of one or more supply entities, one or more material distribution entities, and one or more manufacturing entities. In one or more examples, the steps may be performed by an OEM blockchain node that accesses any transactions added by the various entities on the blockchain node and limits access to transactions on the blockchain by the various entities. Further, the initial transaction may be a main transaction and a transaction representing a commitment by one of the supply entities may be a sub-transaction of the main transaction, and the sub-transaction is closed in the blockchain upon the request for payment for the committed material or payment of the request.

A server computer system, comprises a processor; a communications module coupled to the processor; and a memory coupled to the processor, the memory storing instructions that, when executed, configure the processor to receive, via a user interface displayed on a client device, a signal including a request to transfer data; identify, based on the request to transfer data, a particular data record for receiving the data; determine, based on the particular data record, that a real-time transfer protocol is available to complete the transfer; and in response to determining that the real-time transfer protocol is available to complete the transfer, send, to the client device, a signal enabling a selectable option on the user interface to complete the transfer using the real-time transfer protocol.

The present disclosure discloses a method, device and node apparatus for blockchain permission control. The method comprises: receiving target information sent by a node apparatus; acquiring an account address of a configured account of the node apparatus; acquiring, according to the account address, from a predetermined block stored with the account address and an account permission corresponding to the account address, the account permission corresponding to the account address; and processing the target information according to the account permission accordingly. In the present disclosure, node apparatuses are configured with corresponding accounts, and performing permission control on the accounts can restrict permissions of different node apparatuses so as to ensure security and privacy of blockchain data.

A system and method of optimizing cryptographic mining yields includes analyzing, by a cryptocurrency mining selection system, data associated with factors of interest for one or more cryptocurrencies using machine learning algorithms. Data that is determined to be predictive of the future value of newly mined tokens is used to determine which tokens will have the highest and lowest future values. Based on the predicted value of tokens in the future and the current value of those tokens for each cryptocurrency, the system outputs one or more instructions to buy tokens in cryptocurrencies predicted to increase in value, to sell tokens in cryptocurrencies predicted to decrease in value, and to instruct associated cryptocurrency mining hardware to switch to generating new tokens in one or more selected cryptocurrencies to maximize yields.

In a method and computer system adapted for performing digital asset donation transactions for nonprofit organizations (NPOs), at least one of one or more computing devices ingests digital donation assets from one or more donors intended for a NPO, and then tokenizes the ingested digital donation assets using stablecoin to provide tokenized assets. The tokenized assets are then processed for transfer via ACH to the NPO.

Child/family support payments are made on a multilayered consortium ledger network using blockchain, IoT, and other technologies to expedite the process and disbursement of child/family support payments. The multilayered consortium ledger network may cater to local and/or global child support agencies and/or local and global Parties/Parents/family members who elect to send child/family support payments to their family(ies) outside the traditional child support agencies/district attorney offices. The plurality of technologies used support payments made/received using, but not limited to, domestic/foreign fiat, cryptocurrency, tokens, an/or native tokens.

A system supports asset transfers among blockchains of differing distributed ledger technologies using interop circuitry. The interop circuitry may receive asset permissions from origin and target participant circuitry. The asset permissions may support transfer of an asset from an origin blockchain to a target blockchain. The interop circuitry, acting on behalf of the origin and target participant circuitry, locks an asset on the origin blockchain. Then the interop circuitry creates the asset on the target blockchain. The locking of the asset on the origin blockchain may prevent a double-expend opportunity, where the asset can be redeemed on the origin blockchain and on the target blockchain.

A system supports symmetric release of cryptologically-locked asset transactions. A leading exchange party and a reciprocal exchange party establish, at least in part, a peer challenge in a pre-exchange proposal. The reciprocal party uses the peer challenge to lock a cryptologically-locked asset transaction. The solution to the peer challenge corresponds to an exchange key controlled by the leading exchange party. After establishment of the cryptologically-locked asset transaction, the leading party may request that exchange logic initiate release of the cryptologically-locked asset transaction. In response to the request, the exchange logic may execute a symmetric release of the exchange key and/or signature to the reciprocal exchange party and cryptologically-locked asset transaction (such that the asset is transferred to the leading exchange party).

A system, method, apparatus, and computer software for conducting real-time cross-network counterparty-secure exchange-party-free crypto currency payments, trade, and exchange. The system includes decentralized processing computers operating together peer-to-peer in communication with multiple crypto currency blockchain networks via an internet connection. The method includes requesting a sell or a buy of a Face Value denoted as dx; publishing the request to a market network; accessing transaction data stored in multiple blockchain networks, each of the multiple blockchain networks being different from each other; quoting a value for settlement of the request denoted as dy; verifying the value as according to a predetermined protocol; issuing transactions to effect the request; and producing a trading report. By providing a generalized cryptographic security system, a real-time multiple-access exchange-party-free counterparty-secure exchange is made possible offering a huge market extremely valuable features that are not currently available to crypto currency exchange system users.

A computer-implemented includes sending a public key associated with a particular node in a cyclically-ordered set of nodes participating in a blockchain network to an initiator node; receiving, by the particular node from a node immediately previous to the particular node in the cyclically-ordered set, a first value based on public keys associated with each node from the particular node through to the initiator node; determining a locking value based on the first value and the public key associated with the particular node; and preparing using the locking value, a transaction arranged to transmit control of a resource from a source address associated with the particular node to a receiving address of a node immediately subsequent to the particular node. The control of the resource is to be transmitted responsive to satisfaction of an execution condition including supply of an unlocking value corresponding to the locking value.
