Boaz Bechar has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20260212351
    Abstract: A computer can monitor network traffic on a blockchain computing network. The computer can determine a current level of network congestion on the blockchain computing network. The computer can execute a first machine learning model that predicts a timeseries of future transaction costs based on historical data and the current level network congestion level of the blockchain computing network.  The computer can also execute a second machine learning model to predict a timeseries of future transaction sizes and UTXO types for the distributed ledger-based account based on historical transaction data.  The computer can select one or more UTXOs to use to complete the transaction of the transaction request.  The computer can append a block instance containing an identification of the selected one or more UTXOs to the blockchain to complete the transaction.

  • Patent number: 12506619
    Abstract: A system for controlling access to cryptographic resources is disclosed. The system may receive a request to transfer cryptographic resources between users, including a user identifier and a first cryptographic signature. The system may verify the signature and retrieve an encrypted private key from a key vault using the user identifier. A command to sign the request may be transmitted over a private network to a signature device, which may generate a second cryptographic signature using the decrypted private key. The system may receive the second signature, generate a blockchain operation based on the request and signature, and transmit the operation to a blockchain node for commitment. The system may also handle new account generation, storing encrypted keys in jurisdiction-specific databases, and validating blockchain operations against request parameters.
