Bitcoin Lightning Hold Invoices for Zero Trust Authentication

The patent replaces traditional software-based authentication mechanisms (usernames, passwords, API tokens) with a cryptographic proof-of-work system based on Bitcoin technology. This substitution introduces computational difficulty as a barrier to brute force attacks, where attackers must solve cryptographic puzzles rather than simply guessing credentials. The proof-of-work requirement transforms authentication from a simple credential check into a computationally intensive process that deters automated attacks while maintaining user convenience through one-time token generation.

The patent implements disposable one-time authentication tokens generated via Bitcoin's cryptographic functions. Each token is valid for a single authentication attempt and then becomes obsolete. This eliminates the need for users to remember complex passwords, as each authentication credential is automatically generated, used once, and discarded. The cryptographic nature of these tokens provides security equivalent to complex passwords while maintaining user convenience through automated generation and single-use validity.

The patent replaces the account suspension mechanism with a proof-of-work requirement for each authentication attempt. Instead of penalizing users by locking accounts, the system requires all authentication attempts (including those from legitimate users experiencing issues) to satisfy a cryptographic puzzle. This substitution eliminates false positive lockouts while maintaining security, as the computational difficulty serves as a universal barrier that is easy for legitimate users to clear but prohibitively expensive for automated attack tools.

The patent replaces IP-based rate limiting with cryptographic proof-of-work verification for each authentication attempt. This substitution eliminates the fundamental flaw in rate limiting where multiple legitimate users sharing an IP address are incorrectly penalized. The proof-of-work mechanism evaluates each authentication attempt independently based on cryptographic difficulty rather than source IP, allowing unlimited attempts from shared IPs while still preventing brute force attacks through computational cost. The system counts authentication attempts based on cryptographic verification rather than network origin.

The patent leverages Bitcoin's existing cryptographic infrastructure to provide authentication functionality without requiring separate token generation and management systems. Bitcoin's cryptographic functions (SHA-256 hashing, private/public key pairs, transaction signing) serve multiple purposes: they secure the blockchain network, enable financial transactions, and provide authentication credentials. This multi-functionality eliminates the need for dedicated one-time token systems with their associated registration complexity, as Bitcoin's existing mechanisms can be directly applied to authentication without additional infrastructure.
