There is provided a framework to record to a blockchain unique identification (signatures) of physical items which have unique, random properties. Physical items are analysed using spectral imaging to determine the unique identifications. Hardware is shown to perform the analysis and various nodes of a peer-to-peer network are shown and described, which nodes may be configured to provide proof of location, privacy, trust and authentication. The solution can work even if the item is modified in some way if a subset of the unique properties remain.

Methods, systems, and devices for iterative graph embedding of a blockchain network are described. A blockchain embedding service generates, using a graph representation of a blockchain network and a node embedding model, a first set of node embeddings for a first set of blockchain addresses using transaction data for the first set of blockchain addresses. The platform generates, using the graph representation, a second set of node embeddings for a second set of blockchain addresses associated with new transaction data. Generating the second set of node embeddings includes executing, for each node corresponding to blockchain address of the second set of blockchain addresses, a random walk across a set of nodes starting with the node using the transaction data for the set of nodes, inputting data resulting from the random walk into the node embedding model, and computing a risk score for each of the second set of blockchain addresses.

Digital payment systems and methods leveraging optical tones, blockchain technology, and neuromorphic computing to enhance transaction security and flexibility are disclosed. By initiating transactions with unique optical tones generated through mobile IoT applications, payment instructions are encoded into visually encrypted signals, ensuring high security from the outset. Multi-Factor Authentication (MFA), including advanced facial recognition via Convolutional Neural Networks (CNNs), authenticates users, while Spiking Neural Networks (SNNs) process and filter the optical tones, focusing on pertinent transaction details. The system utilizes blockchain oracles and smart contracts for validating transactions and automating the execution of payment instructions, respectively. A novel aspect of this invention is the ability to generate custom payment tokens, either embedded within optical tones or as separate entities, to facilitate specific transactions. This approach not only significantly enhances the security of digital payments but also introduces unprecedented flexibility in managing financial transactions, setting spending limits, and executing recurring payments.

Systems and methods described herein relate to the execution of locking transactions in a blockchain system. In the context of smart contracts, it may be advantageous to have a public record (e.g., recorded on a blockchain) of a proof of correct execution of a circuit published by a worker and the verification key, thereby allowing anyone (e.g., nodes of the blockchain) to verify validity of the computation and proof. However, there are challenges to recording large blocks of data (e.g., large keys that may comprise multiple elliptic curve points) on the blockchain. For example, in a Bitcoin-based blockchain network, a protocol that utilizes standard transactions may be constrained to locking scripts and unlocking scripts that are collectively not larger than a first predetermined size limit, and the size of a redeem script (if utilized) may be limited to being no more than a second predetermined size limit.
Resumen de: WO2025213464A1
A method for handling blockchain transaction where a client transmits a request to endorse a transaction with a special indication that such transaction should be batched with other transactions to one or more endorsing peers. Moreover, each endorsing peer simulates persisting the transaction invocation request to the ledger and, if the simulation is successful, adds an identifier for the transaction, TxID and invocation parameters to a WriteSet and sends a response to the client. In addition, the client sends an order request for the transaction to an ordering service for the inclusion of the transaction in a block, such as a gossip message received by each peer, which validates and commits the transaction. Moreover, a coordinator invokes a transaction that triggers the batch execution of a group of such pending transactions, such as all transactions of the batch are executed as one transaction representing the impact of all batched transactions.
