摘要： Aspects of the disclosure relate to cryptocurrency. A computing platform may synchronize a database with another database to store account information for a user, which may include establishing a distributed ledger to store the account information, and where the account information includes a balance of fiat currency for the user. The computing platform may receive a request to transfer custody of cryptocurrency, on behalf of the user, to an enterprise organization corresponding to the computing platform. The computing platform may store, using a wrapper database integrated with the database, information of the custody of the cryptocurrency. The computing platform may receive, from a user device of the user, an event processing request. The computing platform may process, using the distributed ledger, the event processing request using one or more of: the fiat currency or the cryptocurrency.

摘要： A system and method for controlling authorization to a protected entity are provided. The method includes: receiving an access request for access to the protected entity, wherein the access request is received from a client device; in response to the access request, causing the client device to perform an admission process that includes performing at least one game; monitoring a distributed database to identify at least one admission transaction designating admission criteria; determining if the admission criteria satisfy a set of conditions for accessing the protected entity; identifying, on the distributed database, completion results of the at least one game, wherein whether the admission criteria satisfies the set of conditions for accessing the protected entity is determined based on the results of the at least one game; and granting access to the protected entity by the client device when the admission criteria satisfies the set of conditions.

摘要： A computer-implemented method for participating in a blockchain-based data record distribution process which includes multiple input addresses for input nodes and multiple output addresses for output nodes. One or more input nodes of the group of input nodes perform steps of: collaborating to determine a stealth address, forming a first transaction that pools data records to be transferred to the stealth address, and transmitting the first transaction to be validated and incorporated into the blockchain. One or more output nodes of the group of output nodes perform steps of: searching the blockchain to find the first transaction, identifying the stealth address, forming a second transaction that distributes pooled data records, collaborating via a threshold signature scheme to sign the second transaction, and transmitting the second transaction to be validated and incorporated into the blockchain. The invention may be used in conjunction with any blockchain implementation.

摘要： A cryptocurrency management device (CMD) may be used to perform various cryptocurrency management functions, such as storage of cryptocurrency, user authentication, and initiation or processing of a transaction for transferring cryptocurrency. To conserve the power resources of the CMD, components of the CMD may be transitioned to a sleep state for extended periods of time. Such components may be automatically activated by a user touching the CMD or bringing a wireless communication device within range of the CMD. The circuitry of the CMD that triggers the activation are capable of continuously monitoring for such inputs over extended periods of time without consuming significant amounts of power, thereby conserving the power resources of the CMD.

摘要： Techniques are presented for securely transmitting a output script or information associated with a payroll and a user between a first node and a second node. The method comprises: determining a symmetric-key based on a common secret, based on a first node second private key and a second node second private key, wherein the second node has the same common secret based on a first node second public key and a second node second private key; encrypting at least part of the output script or information associated with the payroll and the second node with the symmetric-key, to an encrypted output script or encrypted information associated with the payroll and the second node; and sending the encrypted output script or encrypted information associated from the first node to the second node.

摘要： Multiple video game consoles each store a blockchain ledger with multiple blocks, which is either associated with a particular video game or with a the particular type of video game console that the video game consoles are each characterized by. One of the consoles receives a message identifying an intended transaction corresponding to transfer of an identified quantity of an in-game virtual asset from a transferor account to a transferee account. The console verifies that the intended transaction is valid and generates a new block that includes the transaction, optionally one or more additional verified intended transactions, and a block header that includes a hash of a most recent block in the blockchain ledger. The console appends the new block to the blockchain ledger and transmits it to the other consoles, which each also append the new block to their copy of the blockchain ledger, thereby completing the transaction.

摘要： A system is provided for performing transaction mixing between a plurality of users on a blockchain. The system is configured to carry out the steps of: selecting an initiator node to calculate a deterministic hash function using a chosen random number; distribute the deterministic hash function to a plurality of users on the blockchain; choose an amount of time each user is given to construct a payment channel, retrieve the random number, and submit an execution transaction to a blockchain network; choose a second time for when a payment to a user is submitted to the blockchain network; and establish a one-way payment channel between every pair of users in an ordered set of the plurality of users to establish a transaction chain linking all users.

摘要： Systems and methods are disclosed for establishing information on a state of a machine-executable contract in the context of unspent transactions (UTXOs), blockchain and deterministic finite automaton implementation of contracts, and determination of states within those. Stages of a method include determining information of interest and codes or tags identifying that information, constructing metadata associated with those codes or tags, and combining the metadata with a public key for an agent associated with the information. ScriptPubKey values of each script are used to provide keys for constructing a database and mapping the keys from the scriptPubKey values, linked to the information. A derivation of script hash addresses from the scriptPubKey values is used to populate a digital wallet. A search and match algorithm is used to find UTXOs with matching script hash addresses on a blockchain. The database is populated with UTXOs that match the script hash addresses and keys to complete the combinations. A match indicates the state.

摘要： Systems and methods for verifying tokens. The method includes creating a token of a digital title for an asset, the token including proof of ownership of the asset, an identifier of the asset, wherein creating the token further includes signing the token with a private key and embedding the token into a metadata field of the math-based currency (MBC) transaction. The method further includes tracking, using an overlay ledger, an amount of MBC associated with each customer in the MBC transaction, wherein the MBC is a cryptocurrency, and wherein the overlay ledger associates an individual customer with a designated amount of MBC and receiving an asset transfer request regarding the token. The method further includes, responsive to the token being signed with the private key, transmitting a title verification and updating an owner of the token for the asset.
