US 2021/0281579 A1 · SYSTEMS AND METHODS FOR HYBRID BLOCKCHAIN CONTROL

Abstract

Various embodiments of the present application are directed towards systems and methods for hybrid blockchain control. According to some embodiments a method for hybrid blockchain control, an update to a distributed blockchain is received from a blockchain system. The blockchain system includes multiple nodes individually storing copies of the distributed blockchain and individually updating the copies by a consensus process. A determination is made as to whether the distributed blockchain has been fraudulently modified based on the received update. In response to determining the distributed blockchain has been fraudulently modified: 1) a corrective block is disseminated to the blockchain system to trigger the consensus process on the nodes; and 2) a predefined override in the consensus process is invoked to update the copies of the distributed blockchain in a manner that bypasses an illegitimate block. Further, the predefined override is invoked while the consensus process processes the corrective block.

Claims20

Dependent claims

A method comprising:

generating an override block, wherein the override block comprises an override value associated with an override function and further comprises an override secret matched with the override value by a one-way function;
disseminating the override block to a blockchain system, wherein the blockchain system includes multiple computer nodes individually storing copies of a distributed blockchain and individually updating the copies by a consensus process, and wherein the disseminating invokes processing of the override block by the consensus process on the computer nodes;
and
invoking an override in the consensus process to perform the override function on the computer nodes, wherein the override is invoked by a matching combination of override value and override secret while the consensus process processes the override block.

1 more element

A system comprising:

a connection module configured to, by at least one or more electronic processors, receive a first block from a blockchain system, wherein the blockchain system includes multiple computer nodes individually storing copies of a distributed blockchain and individually updating the copies by a consensus process;
and
a consensus module configured to, by the at least one or more electronic processors, perform the consensus process on the first block, wherein the performing of the consensus process comprises determining whether the first block invokes an override in the consensus process and, in response to determining the first block invokes the override, updating a local copy of the distributed blockchain to bypass a second block in the distributed blockchain.
