Systems and methods are provided for minting payment tokens to conduct transactions within a blockchain-based supply chain payment network. The payment tokens can be pegged to fiat currency or digital currency. The payment tokens can be minted by a computing system that is a node in the blockchain-based supply chain payment network. A number of payment tokens to be provided to a network participant as payment can be determined. The network participant can be a supplier associated with the blockchain-based supply chain payment network. The number of payment tokens can be provided for deposit in a digital wallet associated with the network participant as payment. The cryptocurrency tokens can be redeemed as fiat or digital currency.

Methods and systems for automated digital asset transfer are provided. In one aspect, the method can include receiving, by a user interface, configuration parameters comprising an indication of a user wallet address and an indication of a beneficiary wallet address, wherein the user wallet address and the beneficiary wallet address correspond to a blockchain, wherein the user wallet address comprises one or more digital assets. The method can include causing generation, based on the configuration parameters, of a smart contract configured to transfer the one or more digital assets from the user wallet address to the beneficiary wallet address based on a time period of inactivity at the user wallet address. When the time period of inactivity exceeds a threshold time period, the smart contract can be configured to transfer the one or more digital assets from the user wallet address to the beneficiary wallet address.

Disclosed herein are methods, systems, and devices for integration of electric vehicle (EV) charging with virtual reality (VR) environments and/or augmented reality (AR) environments. In one embodiment, a programmatic method includes receiving a presence indication of an EV user within a proximity of an EV charger during a current charging session of an EV and providing a token to a user account associated with the EV user in response to receiving the presence indication.

According to one embodiment, a method, computer system, and computer program product for fractional NFT trading marketplace is provided. The embodiment may include minting a mark associated with an entity as a fractional non-fungible token by a creator with ownership or authority over the mark, where the creator establishes a plurality of parameters during the minting. The embodiment may also include processing one or more purchases of one or more fractions of the fractional non-fungible token by one or more individuals from the creator.

A method for establishing a business is provided. The method includes selling an asset that is to be stored in an electronic device and providing an insurance policy against malicious tampering of the electronic device that results in at least a partial loss of the asset.

A replicated service comprises N replicas deployed on compute nodes of a computer network, wherein the N replicas are each configured to vote on a proposed transaction output by a leader of the N replicas and certify the proposed transaction upon receiving qr*N first votes, where qr is a fractional value between 0 and 1 that represents a quorum required for certification. A method of approving a transaction in the replicated service includes receiving certifications from the N replicas, determining whether or not the certifications are received from at least qr*N replicas during a time period equal to 2*Δ, where Δ represents a network delay between two compute nodes of the computer network, and transmitting an approval of the transaction to the replicas for recording by the replicas upon determining that at least qr*N certifications have been received at the end of the time period equal to 2*Δ.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for allocating resources are provided. One of the methods includes receiving a first request from a first client for accessing a server, wherein the first request includes token information corresponding to resource information of a second client; determining, according to the token information included in the first request, the resource information of the second client corresponding to the token information; receiving resource allocation information from the first client; and allocating resource according to the resource allocation information from the first client and the resource information of the second client.
