A system and method for preventing hacking of blockchain is proposed. The system includes a cryptocurrency owner configured to own a cryptocurrency wallet storing a cryptocurrency, a public key, and a private key, and capable of setting monitoring-subjected data and monitoring-excluded data, a hacking countermeasure system configured to check status of the cryptocurrency wallet by being connected to the cryptocurrency owner to receive the cryptocurrency and the public key, invalidate a hacking transaction when the hacking transaction matching the monitoring-subjected data is received, and allow the cryptocurrency to be traded by opening the cryptocurrency wallet with the private key and process transaction details into a block file when a monitoring-excluded transaction matching the monitoring-excluded data is received, and a blockchain network configured to receive the block file from the hacking countermeasure system and duplicate the block file into a plurality of block files to distribute and store each block file.

Methods and apparatus provide improved stablecoins on a blockchain. The stablecoins are collateralized to fiat-based stablecoins that are loaned to borrowers from a lending pool. Loan payments received from the borrowers are divided into a first portion that buys fiat currency that over-collateralizes the stablecoins and a second portion that pays owners of the stablecoins a fixed rate of interest that does not vary over time.

A method of establishing collaborative breeding parameters using blockchain technology is provided. The method may include providing a first user and a second user. The first user may own a first UIAM (unique identity asset marker) token corresponding to a first genomic asset and the second user may own a second UIAM token corresponding to a second genomic asset. The method may further include providing the first and second UIAM tokens and receiving a Ricardian contract with terms governing ownership rights for offspring. The Ricardian contract may be digitally executed and published on at least one blockchain. The method may further include minting a third UIAM token corresponding to a first offspring of the first and second genomic assets to the at least one blockchain. The third UIAM token may reflect the terms of the Ricardian contract and may evidence lineage of both the first and the second UIAM tokens.

A method for transaction of digital asset is provided, including receiving digital asset transaction request information from a user terminal, verifying, by a blockchain network, the transaction request information, and when the verifying the transaction request information is completed, generating, by the blockchain network, information associated with the digital asset, in which the information associated with the digital asset includes a reputation of the digital asset.

A blockchain configuration may be used to store a distributed ledger for information security and accessibility. One example method of operation may include one or more of logging an asset in a blockchain, identifying a sub-asset linked to the asset, creating a use constraint for the sub-asset, logging the use constraint associated with the sub-asset, and during an access attempt of the sub-asset, prohibiting access to the sub-asset based on the use constraint.

Systems, methods, and computer-readable storage media for receiving, from an issuer, an electronic prescription for a patient, then fulfilling that prescription using a blockchain/distributed ledger verification system. The system receives multiple public keys, combines them, then performs a hash function (or other encryption) on that combination. The resulting output is then transmitted to a pharmacy for prescription fulfillment.

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.

Systems and methods for establishing and fulfilling a smart contract between users and service providers are disclosed. A method includes creating, by one or more nodes in a computer network, a smart contract in response to a request from a user for services and providing the smart contract to a blockchain. The method then includes notifying service providers of the smart contract and receiving responses to the notifications from the service providers. Then the method includes identifying one or more service providers that can complete the service. The method then includes updating the smart contract to include data about the identified service providers. The updated smart contract includes account information for a user account of the user, and account information for service provider accounts of the identified service providers. Then a value interaction is initiated that pushes value from the user account to the service provider accounts.

Some implementations of the disclosure are directed to receiving, at an authentication server system, a distributed ledger address transmitted by a client device to identify itself during an authentication process for accessing a network, where the distributed ledger address corresponds to a distributed ledger network; transmitting an authentication challenge message from the authentication server to the client device; in response to transmitting the authentication challenge message from the authentication server to the client device, receiving at the authentication server, a response to the challenge message including a signature; and using at least the distributed ledger network to determine if the signature used to sign the response to the challenge message is associated with the distributed ledger address transmitted by the client device.

The present disclosure describes transaction-enabling systems and methods. A system can include a facility including a core task including a customer relevant output and a controller. The controller may include a facility description circuit to interpret a plurality of historical facility parameter values and corresponding facility outcome values and a facility prediction circuit to operate an adaptive learning system, wherein the adaptive learning system is configured to train a facility production predictor in response to the historical facility parameter values and the corresponding outcome values. The facility description circuit also interprets a plurality of present state facility parameter values, wherein the trained facility production predictor determines a customer contact indicator in response to the plurality of present state facility parameter values and a customer notification circuit provides a notification to a customer in response.
