There is provided a transaction system that includes a plurality of computing nodes that are mutually interconnected via a data communication network to exchange encrypted data therebetween. The transaction system employs a blockchain whose entries are recorded in a ledger. A directed acyclic graph (DAG) is utilized for defining relationships between blocks of the blockchain. The DAG comprises a plurality of proposed solutions to problems posed in the one or more smart contracts. Each of the one or more smart contracts includes machine-readable elements including at least one of: a data specification, an initial mining algorithm, an objective function for scoring the plurality of proposed solutions. The transaction system operates to cause the DAG to store temporary data and/or extended algorithm code used during an execution of a given transaction, wherein the temporary data and/or extended algorithm code stored in the DAG is to be removed once the execution of the given transaction is complete, further wherein the temporary data and/or extended algorithm code stored in the DAG is to be modified in response to new solutions arising during operation of the transaction system. The transaction system operates to accommodate a given smart contract defining a problem that is to be solved, giving a plurality of parties of the transaction system an opportunity to receive consideration when the problem is solved, and wherein the consideration is a quantity representing at least one of: an access to data storage, an access to data memory, an access to data communication system bandwidth, access to data communication channels or ports, data processor energy use, data processor energy dissipation, an access time taken by data processing resources during transactions, heat generation in computing hardware, cooling energy applied to computing hardware or any other measure associated with one or more CPU cycles.

Transaction system and method of operation thereof

Disclosed is a resource management system that maintains records relating to transactions associated with resources, wherein the system is implemented as a distributed ledger arrangement including data processing nodes that are coupled via a data communication network. The records are maintained in corresponding chains, wherein each chain includes a temporally defined sequence of verified entries and each entry defines corresponding transactions. When new entry is to be made to a given chain, information concerning the new entry is communicated to the data processing nodes for verification thereof. The system records the new entry when verified, to its corresponding given chain. The system includes a filter arrangement for limiting communication regarding the new entry to be made only to a subset of the data processing nodes of the system for verifying the new entry.

Resource management system and method of operation thereof

Disclosed is a data processing system that processes data therein and a method of using the data processing system. The data processing system includes a plurality of data processing nodes that are coupled together via a data communication network arrangement. The data processing system distributes a plurality of computing tasks across plurality of data processing nodes, wherein plurality of computing tasks are distributed according to a directed acyclic graph (DAG) allocation arrangement, wherein the DAG allocation arrangement employs consensus voting arrangement employing recursive elections of nodes or users of data processing system to control operation of the DAG allocation arrangement to incentivize participation of the plurality of data processing nodes to process the plurality of computing tasks and wherein the DAG allocation arrangement is associated with a ledger arrangement operable to control or record execution of the plurality of computing tasks.

Data processing system using directed acyclic graph and method of use thereof

Disclosed is a system having an input arrangement and an output arrangement. The system includes a plurality of data processing nodes to processes input data and generates output data, depending on operation of a distributed ledger arrangement to which an entry is added. A directed acyclic graph (DAG) is utilized to agree upon a set of data transactions required for adding the entry to the distributed ledger arrangement. The system employs decentralized beacon arrangement that randomly elects data processing nodes that operate to form consensus of entry to be added to the distributed ledger arrangement, pseudo-random number generator engine to rank the data processing nodes within the group; and control arrangement that enables the leading node to provide final proposal to be included in the DAG, wherein a remainder of the data processing nodes operate to notarize the final proposal to add the entry to the distributed ledger arrangement.
