  • Patent number: 11556948
    Abstract: A method for awarding blockchain mining fees based on recycling efforts includes: receiving recycling data for each of a plurality of mining systems including an amount of recycled materials associated with the respective mining system; receiving validation data for each mining system from third party entities including, for each mining system, a confirmation of the amount of recycled materials for the respective recycling data; selecting one of the mining systems, which is weighted based on the amount of recycled materials for the respective mining system compared to a total amount of recycled materials for all mining systems; and receiving a new block generated by the selected mining system including a block header and a plurality of blockchain data values including a blockchain data value corresponding to a blockchain transaction for payment of mining fees for the new block to a wallet associated with the selected mining system.
    Type: Grant

  • Patent number: 11373175
    Abstract: A method for processing redundant blockchain transactions for linked wallets includes: storing blockchain data associated with a blockchain including a plurality of blocks, each block including a block header and blockchain data values, each data value corresponding to a processed blockchain transaction; receiving a new blockchain data value including an input transaction, recipient address, and transaction amount; confirming each input transaction based on a corresponding blockchain data value; identifying a plurality of blockchain wallets linked to the recipient address, and, for each wallet, an additional recipient address; generating a mirror blockchain data value for each linked wallet including the input transaction, transaction amount, and the additional recipient address identified for the respective linked wallet; and transmitting the new blockchain data value and each mirror blockchain data value to one or more nodes in a blockchain network associated with the blockchain.

  • Patent number: 11032078
    Abstract: A method for providing additional security for a blockchain wallet through the use of a dynamic pseudo key confirmed through digit positioning includes: storing digit pairs, each including a predefined value and a character position; receiving a dynamic pseudo key and transaction information, where the key includes characters in set positions and the transaction information includes a destination address and data value; validating that the dynamic pseudo key has not been used for a prior blockchain transaction; validating that the characters in set positions in the dynamic pseudo key includes the predefined value in the corresponding character position for each of the digit pairs; generating a digital signature using a private key after successful validation of the dynamic pseudo key; and transmitting the digital signature and transaction information to a node in a blockchain network associated with a blockchain.

  • Patent number: 11025431
    Abstract: A method for two factor authentication for a blockchain transaction includes: storing a data pair including a public key of a first cryptographic key pair and an expected data value; receiving a transaction request including a first digital signature, one or more input addresses, one or more output addresses, and at least one transaction amount; identifying a processed transaction in a sidechain including a destination address and a transaction data value, wherein the destination address is generated using the public key of the first cryptographic key pair; performing a first authentication by validating the first digital signature using the public key of the first cryptographic key pair; performing a second authentication by validating the transaction data value using the expected data value; and transmitting the received transaction request to a plurality of other nodes in a blockchain network.
