TRANSACTION PROPOSAL METHODS AND CONSENSUS NODES IN BLOCKCHAIN SYSTEMS, AND BLOCKCHAIN SYSTEMS

Resumen de: US2025392486A1

Described is blockchain system transaction proposal applied to any target consensus node that has blockchain system transaction proposal permission. The blockchain system includes a plurality of consensus nodes that have transaction proposal permission. Local transaction pools of the consensus nodes include duplicate transactions. A digest value of a transaction maintained in a local transaction pool is calculated. An arithmetic operation is performed on the digest value and a predetermined value. Based on an operation result of the arithmetic operation, determining whether the target consensus node has transaction proposal permission for the transaction. If the target consensus node has transaction proposal permission for the transaction, the transaction is added to a pending-consensus transaction set proposed by the target consensus node for a pending-consensus target block.

SOFTWARE ARCHITECTURE FOR EFFICIENT BLOCKCHAIN TRANSACTIONS

Resumen de: US2025390866A1

The present disclosure provides techniques for efficient blockchain transaction processing. In one embodiment, a computer system broadcasts a first transaction to a blockchain network for addition to a block in a blockchain. The computer system may broadcast a second transaction to the blockchain network for addition to the block in the blockchain, where the second transaction descends from the first transaction and includes a placeholder fee. The computer system monitors and determines that the first transaction has not been confirmed to the block in the blockchain for a duration of time (e.g., stuck in the mempool). In response to determining that the first transaction is stuck, the computer system may transmit a request to replace the placeholder fee with a transaction fee that is sufficiently high to cause the first transaction and the second transaction to be confirmed to a block in the blockchain, thereby unsticking the first transaction.

Blockchain-Based Encrypted Voting System and Method of Use

Resumen de: US2025384729A1

The present invention is a secure blockchain-based voting system. The system includes a mobile application that enables voters to register, authenticate via biometrics and another factor (i.e., two-factor verification), and cast votes using a color-coded ballot interface. Each vote is encrypted, digitally signed with the voter's private key, and broadcast to a blockchain network of nodes for validation and secure storage. Blockchain nodes implement smart contracts to automate processes such as vote recording and duplicate vote prevention. Validated vote transactions are grouped into blocks, which are then replicated across all nodes to maintain an immutable, synchronized voting ledger. An audit trail, including timestamps and unique transaction IDs, is also generated.
