Embodiment Construction

[0061] blockchain network

[0062] first reference Figure 1A , Figure 1A An exemplary blockchain network 100 associated with a blockchain is shown in block diagram form. A blockchain network can be a public blockchain network, which is a peer-to-peer open membership network in which anyone can join without invitation or consent from other members. Distributed electronic devices running instances of the blockchain protocol under which the blockchain network 100 operates may participate in the blockchain network 100 . Such distributed electronic devices may be referred to as nodes 102 . The blockchain protocol can be, for example, the Bitcoin protocol.

[0063] The electronic devices that run the blockchain protocol and form the nodes 102 of the blockchain network 100 can be various types of devices, for example, computers such as desktop computers, laptop computers, tablet computers, servers, such as smart phones, etc. Mobile devices, wearable computers such as smart watch...

Abstract

There may be provided a blockchain-implemented security method. It may be implemented using a blockchain network. Embodiments of the blockchain-implemented security method involve a first party and asecond party. The blockchain-implemented security method generates a plurality of n cryptographic locks based on combinations of encrypted versions of a first plurality of n secrets generated by the first party and encrypted versions of a second plurality of n secrets generated by the second party. One secret belonging to the first plurality of n secrets generated by the first party is randomly selected. And a cryptographic key that unlocks a particular cryptographic lock of the plurality of n cryptographic locks is generated, wherein the particular cryptographic lock corresponds to the randomly selected one secret belonging to the first plurality of n secrets generated by the first party.

Description

technical field [0001] The present invention relates generally to distributed systems, and more particularly to methods and systems for improving the reliability and availability of cryptographically enforced assets, including cryptocurrencies, maintained on blockchains. Background technique [0002] In this document, we use the term "blockchain" to include all forms of electronic, computer-based distributed ledgers. They include, but are not limited to, 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. While reference may be made to Bitcoin herein for convenience and illustrative purposes, it should be noted that the present invention is not limited to use with the Bitcoin blockchain and that alternative blockchain implementations and protocols...
