A computer-implemented method of purchasing gifts includes under control of one or more configured computing systems, selecting a gift item desired by a gift recipient, maintaining a list for the gift recipient that includes the selected gift item, and assigning a sales price to the selected gift item on the list. On a visual display, a processor is used for dividing the selected gift item into two or more gift parts that are available for individual purchase by gift contributors. The selected gift item is divided into the two or more gift parts on the visual display by showing a boundary on the visual display that defines a bounded area, showing the selected gift item on the visual display, inside the bounded area and surrounded by the boundary, and generating at least one dividing line inside the bounded area that divides the bounded area into two or more individual sections that are visible on the visual display, whereby each of the gift parts is located inside a different one of the individual sections. A monetary value is assigned to each of the respective gift parts that is less than the sales price assigned to the selected gift item. Gift contributors can purchase at least one of the gift parts at the monetary value assigned thereto and leave comments that are unique to the gift part.

Systems and methods include a group fund processor having a communications interface that receives account data associated with a primary account from a device over a network, creates a group fund account, and associate one or more limits with the group fund account, an alert interface that transmits an electronic invitation including a description of a first amount to an invited user and receives a response from the invited user to the at least one invitation, wherein the response includes account data associated with a respective group member account of the invited user; and an account processor that links the group fund account to the primary account, and links respective group member account of the invited user to the group fund account so that the first amount is transferred from the respective group member account of the invited user to the group fund account.

A method includes selectably controlling a power supply from a solar Direct Current (DC) power system and an Alternating Current (AC) power system to a computing system including one or more data processing device(s) using an electronic control system, and continuously updating, through a computing power management system associated with the electronic control system, a power consumption requirement of execution of a high computational workload through the one or more data processing device(s) based on analyzing prior energy usage/production and/or predicted energy usage/production relevant to the execution of the high computational workload. The method also includes optimizing the power supply from the solar DC power system to the one or more data processing device(s) using the computing power management system based on the continuously updated power consumption requirement of the execution of the high computational workload.

A method includes selectably controlling a power supply from a renewable energy source based power system and an AC power system and/or a DC power system to a cryptocurrency system including a number of mining servers using an electronic control system, and continuously updating, through a mining node power management system associated with the electronic control system, a power requirement of mining a specific type of cryptocurrency through the cryptocurrency system based on analyzing statistically predicted patterns of energy usage and production relevant to the mining of the specific type of cryptocurrency in accordance with utilizing a predicted energy consumption pattern provided through the mining node power management system. The method also includes optimizing the power supply from the renewable energy source based power system to the number of mining servers using the mining node power management system based on the continuously updated power requirement of the mining.

Transaction-enabled methods for providing provable access to a distributed ledger with a tokenized instruction set for polymer production processes are described. A method may include accessing a distributed ledger comprising an instruction set for a polymer production process and tokenizing the instruction set. The method may further include interpreting an instruction set access request and providing a provable access to the instruction set. The method may further include providing commands to a production tool of the polymer production process and recording the transaction on the distributed ledger.

A method of transferring cryptocurrency credits employs leaf blocks to transfer cryptocurrency credits which are settled by cryptocurrency through blockchain transaction(s). It comprises: maintaining two types of accounts—one for cryptocurrency and the other for cryptocurrency credits; creating at least a leaf block, by a sending financial institution, containing a plurality of business transactions that intend to transfer customers' cryptocurrency credits to customers at a receiving financial institution; calculating a mathematical summary of said leaf block; creating at least a blockchain transaction tying to said leaf block through said mathematical summary serving as a settlement to said leaf block; submitting said blockchain transaction to a blockchain; sharing said leaf block with the receiving financial institution; accessing said leaf block by the receiving financial institution, validating it and crediting transaction amounts in it to corresponding customer accounts at the receiving financial institution. A system configured to implement said method.

A collaborative ordering and payment method comprising: (a) generating a bill number; (b) ordering one or more items associated with the bill number, wherein the one or more items are ordered by a plurality of users; (c) dividing the ordered items among the plurality of users and calculating an amount owed by each user; and (d) processing payment by one or more of the users to fulfill a total amount owed.

Based on detecting a selection, by a first user, of a group payment option on a merchant interface, the computer system launches a user selection user interface that includes one or more user selection interface elements that correspond to one or more users associated with the first user. Based on detecting a selection of one or users, the computer system launches a group payment user interface that includes one or more payment allocation user interface elements that corresponds to a payment allocation for the selected users. Based on detecting a confirmation of a first payment allocation plan, the computer system processes a payment for the purchase and further transmits invoices to the selected users which include an allocated payment amount.

A system and a method for tracking repayment status of a transaction split across multiple systems is disclosed. In some examples, a system is configured to receive a notification of a transaction that has occurred with a merchant for a transaction account. The system is configured to initiate a split of the transaction based at least in part on a selection of a user interface element and display a user interface for identifying a selection of a peer-to-peer system for a selected contact of the transaction. A funds request is transmitted and includes an identifier for the selected contact at the peer-to-peer system. A user interface is displayed provides a repayment status for the fund request transmitted for the identifier.
