BLOCKCHAIN-IMPLEMENTED METHODS AND SYSTEMS FOR AUTHORISATION BASED ON BILINEAR MAP ACCUMULATORS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240022425 titled 'BLOCKCHAIN-IMPLEMENTED METHODS AND SYSTEMS FOR AUTHORISATION BASED ON BILINEAR MAP ACCUMULATORS

Simplified Explanation

The invention described in this patent application relates to distributed ledger technologies, specifically consensus-based blockchains. It involves computer-implemented methods for locking and unlocking transaction inputs and outputs using a blockchain network. The invention utilizes a group of entities that form a group, and membership in this group can be proven using an accumulation tree. The accumulation tree can be generated using various methods, including those that involve a central authority or a decentralized protocol. One key aspect of this invention is that parties can unlock transaction outputs based on group membership without revealing their identity.

  • The invention relates to distributed ledger technologies, specifically consensus-based blockchains.
  • It describes computer-implemented methods for locking and unlocking transaction inputs and outputs.
  • The invention is implemented using a blockchain network.
  • A group of entities forms a group, and membership can be proven using an accumulation tree.
  • Various methods are described for generating the accumulation tree, including those involving a central authority or a decentralized protocol.
  • Parties can unlock transaction outputs based on group membership without revealing their identity.

Potential Applications:

  • Secure and private transactions within a group or network.
  • Identity verification and authentication without revealing personal information.
  • Supply chain management and tracking.
  • Financial transactions and smart contracts.
  • Voting systems and governance.

Problems Solved:

  • Maintaining privacy and confidentiality in transactions.
  • Ensuring secure and tamper-proof record-keeping.
  • Verifying group membership without disclosing individual identities.
  • Enabling trust and consensus in decentralized networks.
  • Improving efficiency and transparency in various industries.

Benefits:

  • Enhanced privacy and security in transactions.
  • Reduced reliance on centralized authorities.
  • Increased trust and transparency in decentralized networks.
  • Improved efficiency and cost-effectiveness in various processes.
  • Potential for innovation and new business models.


Original Abstract Submitted

the invention relates to distributed ledger technologies such as consensus-based blockchains. computer-implemented methods for locking and unlocking transaction inputs and outputs are described. the invention is implemented using a blockchain network. a group of entities form a group in with membership may be proven using an accumulation tree. a variety of methods are described for generating the accumulation tree, including methods that use a central authority and methods that use a decentralized protocol in place of the central authority. in various implementations, parties are able to unlock transaction outputs that are based on group membership without revealing their identity generally.
