Systems and techniques to protect against abuses in the transfer and maintenance of tokens within NFT platforms are illustrated. One embodiment includes a method to facilitate filtration in blockchains. The method recovers, from a list of prospective entries to be appended to a primary blockchain, a reference to a blockchain entry. The method obtains a certainty level associated with the blockchain entry. The method assesses a classification of the blockchain entry based on the associated certainty level. The method determines whether to record the blockchain entry on the primary blockchain based on the classification.

An information processing system includes a server, plural block chain nodes, and plural terminals. Each of the plural block chain nodes reads from a block chain each first transaction data that is past transaction data linked to a second transaction data broadcast by the server. Each of the plural block chain nodes verifies whether or not a generation target item of the second transaction data is configured by a raw material contained in a generation source item of the first transaction data based on a relationship between a commitment value of the generation target item contained in the second transaction data and a commitment value of the generation source item contained in the first transaction data.

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.

Disclosed herein are methods and systems to facilitate a blockchain-backed peer-to-peer transaction without requiring the recipient's personally identifiable information and without updating the recipient's blockchain. A central server may receive a transaction request from a sender and may identify a system blockchain associated with the sender. When the server determines that the sender's accounts can satisfy the request, the server generates a unique transaction token. The server then transmits the unique transaction token to the sender, recipient (if indicated within the sender's request), and one or more electronic terminals. When the server receives an indication that the recipient has inputted the unique transaction token to the electronic terminal, the server appends a block instance corresponding to the transaction to the system blockchain.

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.

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.

This invention presents an advanced blockchain-based system for the precise tracking and authentication of supply chains for precious metals, base metals, and other minerals. Leveraging a blockchain network, it forms an immutable ledger that records all transactional data from extraction to final sale. Users engage with an intuitive interface for detailed entry of metadata, timestamps, and cryptographic signatures, with each entry undergoing verification using consensus algorithms before secure addition to the blockchain. The aggregation of multiple transactions forms a block, ensuring a transparent, traceable, and tamper-proof record of the entire supply chain, verifying mineral origins and provenance. The system empowers artisanal miners by providing direct access to international markets, enhancing their economic opportunities, and enables consumers to understand product origins, promoting ethical purchasing. Its architecture enhances supply chain security, tracking accuracy, and ethical standards, particularly in the jewelry and electronics markets, significantly reducing fraud and improving sustainability.
