Problems solved by technology

This introduction necessarily requires network communication, and thus may have the side effect of exposing information about the originator of the transaction at the network layer (such as Internet Protocol (IP) address)

Embodiment Construction

[0040] In the present invention, the term "and / or" is intended to cover all possible combinations and sub-combinations of listed elements, including any one, any sub-combination, or all elements of the individually listed elements, without necessarily excluding other elements.

[0041] In the present invention, the phrase "at least one of ... or ..." is intended to cover any one or more of the listed elements, including any one, any subcombination, or all of the listed elements individually. Any other elements are not necessarily excluded, nor are all elements required to be included.

[0042] overview

[0043] Many blockchain-based systems are generally considered anonymous. For example, ledger systems such as Bitcoin are generally considered anonymous because Bitcoin allows parties to send and receive units of one or more commodities without requiring the parties to reveal personal or identifying information. However, such systems may be considered pseudo-anonymous, rather...

Abstract

A blockchain-implemented transaction from an originator node is to be broadcast. The originator node is communicatively coupled to proxy nodes. The method, implemented by a proxy node, includes: receiving a transaction including an input taking x+r units of computing resources, an output providing x units to the output address and another output providing d+r units to a 1-of-n multi-signature address unlockable by any one of a set of private keys associated the proxy nodes. The proxy node selects a quantity of computing resources, t units, to be allocated to the proxy node for broadcasting thetransaction and having it included in the blockchain and generates a further transaction taking d+r units sourced from the multi-signature address and an output providing t units to the proxy node. The proxy node broadcasts both transactions timed to permit their inclusion in the same block of the blockchain.

Description

technical field [0001] The present invention relates generally to network communications and cryptography, and more specifically, to the communications of blockchain transactions with blockchain networks and the encryption techniques used to conceal the origin of those communications. Hiding the identity of originator nodes associated with introducing transactions into a blockchain network enhances privacy and security. Background technique [0002] In this article, the term "Blockchain" is used to include all forms of computer-based electronic distributed ledgers. These electronic distributed ledgers include consensus-based blockchain and transaction chain technologies, permissioned and permissionless ledgers, shared ledgers, and variations thereof. While other blockchain implementations have been proposed and developed, the most widely known application of blockchain technology is the Bitcoin Ledger. Although reference is made to Bitcoin (Bitcoin) herein for purposes of ...
