Methods and systems for use in a blockchain network are presented. A method comprises: associating identification information with a private key or with a custodian of the private key, wherein the identification information enables initiation or execution of one or more distributed ledger-based computing operations in the blockchain network; accessing, by at least one first computing device in the blockchain network or at least one second computing device in the blockchain network, an issuance digital facilitator for facilitating the initiation or execution of the one or more distributed ledger-based computing operations in the blockchain network, the one or more distributed ledger-based computing operations in the blockchain network involving the at least one first computing device or the at least one second computing device; and connecting the identification information associated with the private key or the custodian of the private key, to the one or more distributed ledger-based computing operations.

Systems and methods for managing cryptocurrency systems.

A computing system can establish asynchronous network communications with exchanges to facilitate cross-medium transactions between originating and recipient clients. Such communications can result in filtering out errant responses that would otherwise cause an open transaction to fail.

A gateway interfacing with multiple distributed ledger networks may receive, from a buyer on a first distributed ledger network, a request to purchase an asset in exchange for a cash token, the asset being sold by a seller on a second distributed ledger network and an entry on the second distributed ledger network, and the cash token is an entry on the first distributed ledger network; communicate the request to the seller; receive acceptance of the request from the seller; transfer the asset to an electronic wallet for the buyer by updating ownership of the asset on the second distributed ledger network and on the first distributed ledger network; and transfer the cash token to an electronic wallet for the seller by updating ownership of the cash token on the second distributed ledger network and on the first distributed ledger network.

A financial services system that utilizes a user device and a blockchain having a blockchain ledger includes. a host database having a non-transitory computer-readable medium including code and a host controller that executes the code. The host controller enables communication between a first digital wallet on the user device and one of a local currency account and a digital currency account to initiate a deposit via one of the currency accounts. The deposit can be assigned a transaction ID that is recorded to the blockchain ledger. The transaction ID can include a deposit currency value. A method for transferring currency includes the steps of enabling communication between a first digital wallet on a user device and one of a local currency account and a digital currency account with a host controller of a host database to initiate a deposit via one of the currency accounts, assigning a transaction ID to the deposit, and recording the transaction ID that includes a deposit currency value to a blockchain ledger.

In a method of providing cryptocurrency cashback using blockchain technology, in which when cryptocurrency is transferred from the payer's electronic wallet to the affiliated store's electronic wallet according to payment via cryptocurrency using blockchain technology, the payment server 200 provides cryptocurrency cashback, an embodiment of the disclosure provides credits proportional to the amount of payment, as cashback, to the payer's credit electronic wallet, and the affiliated store receiving the amount of payment deducts points proportional to received points from the received points and stores in the affiliated store's credit electronic wallet.

In one implementation, a computer-implemented method is executed on a computing device and includes: receiving general collateral assets from a first market participant for a trading platform; storing the general collateral assets within a trading platform account managed by a third party platform and associated with the trading platform; and collateralizing matched orders between the first market participant and the trading platform with the general collateral assets.

A method for use in a hybrid network ecosystem comprising an enterprise network and a reconciliation network, the method comprising generating, by at least one first computing node in the enterprise network or the reconciliation network, a first digital facilitator, wherein the first digital facilitator enables a first device to use a private key to access data associated with a distributed ledger operation. The method also comprises transmitting, via the reconciliation network, the data from the first computing device to a second computing device, wherein the first computing device and the second computing device are connected via the reconciliation network.

A method can include generating a cryptogram by encrypting, by a hardware security module (HSM), a keyed-hash message authentication code (HMAC) key by a master key encryption key (MK); transmitting, a database server, the cryptogram; destroying the cryptogram at the HSM, in response to the transmitting the cryptogram to the database server; receiving, from the database server, the cryptogram and an ID generated by the database server; generating a wallet password based on the ID and the cryptogram; generating a data encryption key (DK) retrievable via the wallet password; transmitting, to the database server, the DK without the wallet password; destroying the wallet password in response to the transmitting the DK to the database server; decrypting the cryptogram into a decrypted HMAC key; regenerating the wallet password using the ID and the decrypted HMAC key; encrypting the regenerated wallet password; transmitting, to the database server, the encrypted regenerated wallet password.

System and method for synchronizing blockchain nodes by using snapshots.
