Some embodiments include receiving, a request from the wireless client associated with the first mobile network to send a first value to a wireless client associated to a second mobile network, then checking at the first mobile network operator, if the first subscriber database includes the requested first value associated with the wireless client if the first subscriber database includes at least the requested first value associated with the wireless client associated with the first mobile network, and sending a message indicating the requested first value from the first mobile network operator to a second mobile network operator.

Techniques for providing a secure mesh network based on a cryptocurrency blockchain are provided. An electronic device can receive data from a mesh network to establish the device as a node on the mesh network. The established node can generate a cryptocurrency wallet that can be loaded with an amount of cryptocurrency. The established node can receive a payment for facilitating transfers on the mesh network including routing transactional or communication data. Public and/or private keys associated with the cryptocurrency wallets can be used to encrypt communications, thereby providing a secure mesh network. Further, the blockchain, which can be managed by one or more authorized nodes of the mesh network, can provide a payment system within the mesh network. The distributed nature of the mesh network allows it to operate securely without a central authority. In turn, the mesh network is more adaptable and flexible.

A system for performing transaction mixing between a plurality of users on a blockchain is provided. The blockchain may be, for example, the Bitcoin blockchain. The system is configured to carry out the steps of: (i) preparing a first commitment transaction arranged to transmit control of a resource from a source address of a first user to a receiving address of a second user; (ii) preparing a second commitment transaction arranged to transmit control of a resource from a source address of the second user to a receiving address of a further user; (iii) preparing a further commitment transaction arranged to transmit control of a resource from a source address of the further user to either: (a) a receiving address of the first user; or (b) a receiving address of a yet further user and repeating step (iii) until option (a) is performed to complete a transaction chain; and (iv) executing the transaction chain. At least one of the users is randomly chosen from the plurality.

Methods and systems are disclosed for enabling the creation of substitute low-value token creation, comprising providing software content to a content delivery network wherein, when transmitted to a user browser, the software content is configured to enable the user browser to create a substitute low-value token if a token service is unavailable, wherein the content delivery network is configured to provide the software content to at least one user browser, and receiving the substitute low-value token from a merchant system, the substitute low-value token having been generated by the user browser in response to the user browser being unable to obtain a low-value token from the token service.

A fork in a block chain data structure is identified, the block chain data structure including a first set of blocks each describing a respective transaction. The fork includes a first branch beginning with a first block and a second branch beginning with a different second block. The first branch includes a first set of blocks comprising at least the first block, and the second branch includes a second set of blocks including at least the second block. A determination is made, based on a consensus protocol, that the second branch is to be discarded. Accordingly, a meta block is generated to identify and describe the second branch. The meta block is to be included in a meta block chain data structure. The meta block chain data structure is separate from the block chain data structure and comprises meta blocks to record orphan branches of the block chain data structure.

A system and method for arbitrating a blockchain transaction enables a sender node and a receiver node to perform a transaction with a payment contract, and also record the transaction in the blockchain to protect the sender and receiver node from unfair practices; by preventing the receiver node from transferring received payments until a dispute resolution period that is preset by the sender node has expired. The transaction and payment contract are conducted with a payment condition-checking smart code that executes the transaction only when predetermined conditions have been met. The sender node and the receiver node can elect arbitrator nodes through a delegated proof of stake process. The arbitrator nodes verify the transaction, and review submitted arbitration applications. The arbitrator nodes create an arbitrator report recorded in the blockchain. If dissatisfied with the arbitration, a subsequent arbitration, or an offline dispute resolution node can be requested.
