A computer-implemented method includes: determining assets held by a remitter, the assets to be spent in a remittance transaction between the remitter and one or more payees, in which each asset corresponds to a respective asset identifier, a respective asset amount, and a respective asset commitment value; determining a remitter pseudo public key and a remitter pseudo private key; determining a cover party pseudo public key, in which the cover party pseudo public key is obtained based on asset commitment values of assets held by the cover party; and generating a linkable ring signature for the remittance transaction.

A system for a mobile digital currency exchange is disclosed. The system may receive a sign-in data. The system may generate an authentication request based on the sign-in data. The system may receive an authentication data. The system may display a trading interface comprising a portfolio drawer based on the authentication data, wherein the portfolio drawer is configured to display an instrument detail and an account summary.

Systems and methods for secure resource management are provided. A secure resource management system includes a blockchain-based computing network configured to host a blockchain for generating a digital object to represent a resource associated with a physical object and transferring the digital object to a secure network address associated with a user. The secure resource management system further includes a database configured for storing data in the blockchain and a services layer system for communicating with the blockchain and the database by requesting the blockchain to generate the digital object, storing the identifier of the digital object in the database, requesting the blockchain to transfer the digital object to a secure network address associated with a user and updating the database to indicate that the digital object is assigned to the user.

The Vehicle Appearance Protection and Enhancement Apparatuses, Methods and Systems (APEPS) transforms initial product attribute data inputs via APEPS components into future product value enhancement verification outputs. In various aspects of the various embodiments of the APEPS system, an Automotive Appearance Protection Trade Credit, voucher, coupon, allowance, guarantee, etc. is provided to a user. The trade credit may equal a percentage, flat dollar amount, or dollar for dollar up to a maximum amount of the original automotive appearance protection/product purchase/lease price. The customer is provided with tangible value upon leaving a dealership, which states that by applying these products/protections the vehicle trade-in value will be enhanced. The APEPS provides a web portal for both customers and dealers that will automatically calculate and continuously update the trade credit.

In some embodiments, the present description provides a computer-based system having a dual-exchange cryptographically-secured platform (DECSP); where the DECSP includes: a first-type cryptographically-secured platform (first-type CSP) and a second-type cryptographically-secured platform (second-type CSP); where the first-type CSP includes a first computing device; where the second-type CSP includes a second computing device; where the first computing device is connected to a blockchain and configured to issue crypto-tokens associated with a non-crypto asset, perform blockchain-based activities, and automatically transmit an instruction associated with the non-crypto asset to a second computing device in response to an issuance of the crypto-token by the first computing device; where the second computing device is configured to: receive the instruction associated with the one non-crypto asset from the first computing device and automatically communicate with a non-crypto asset electronic marketplace to execute a transaction associated with the non-crypto asset to obtain a position in the non-crypto asset.

Embodiments of the present invention provide a system for resource distribution within an offline environment. A merchant device internally stores a repository of reference codes and managing entity public keys that are paired with managing entity private keys. The user requests an amount of resources for offline exchange from the managing entity system. The managing entity system transmits certain authorization and encryption information to a user device. When the user device receives an exchange prompt from the computing device of the merchant through near field communication, it generates a digital token incorporating layers of content encryption ending with a managing entity's private key. The encrypted token and reference code are transmitted via near field communication to the merchant device. The merchant device matches the reference code to the managing entity public key and decrypts portions of the token with the managing entity public key to acquire the usable exchange information.

Apparatus and methods are provided for an online banking portal having adjustable display settings for transactions executed by a credit card. The credit card may have a first user and a second user. The online baking portal may have computer-readable media for performing the method steps of storing a first display setting and a second display setting. The first display setting may define first purchase information for displaying on a user portal in connection with a credit card purchase. The second display setting may define second purchase information for displaying on a user portal in connection with a credit card purchase. The second purchase information may include less information than the first purchase information.

The disclosed computer-implemented method for pooling and transferring digital assets may include detecting a transaction event for a blockchain ledger. The blockchain ledger may include transaction records for a pool of digital assets and accounts collectively owning the digital assets. Each account may own a proportional portion of the digital assets corresponding to an account asset balance. The method may also include calculating an exchange rate based on a cash balance of the pool, a liabilities balance of the pool, and an ownership distribution value. The ownership distribution value may be based on a distribution of the account asset balances. The method may also include updating the cash balance based on the exchange rate and the transaction event, and adding a transaction record for the transaction event to the plurality of transaction records. Various other methods, systems, and computer-readable media are also disclosed.

Disclosed are systems and methods that utilize multiple single asset types and blockchain-based ledgers utilized by a custodian to issue a digital representation of assets held by the custodian. Trading entities place, with the custodian, respective assets that are represented on the ledgers. Genesis blocks on each blockchain-based ledger are signed by the exchange network which provides the initial trust and acts as a barricade against a rogue node from entering the network. Trading entities use the exchange network to agree on a price and enter into trades. The trades can include one asset type for another asset type. An atomic exchange is performed, and a trade is complete. Changes to token ownership are recorded on respective custodian ledgers automatically and redemption occurs upon request by a trading entity such that the ledger can be updated in actual currency and moved from the custodian to a trading entity account.

A system and method for implementing a marketplace for risk assessed smart contracts issuers and execution providers in blockchains in a computer environment are presented. A smart contract, issued by one or more blockchain nodes to a secondary blockchain and accepted by a primary blockchain, may be executed following a risk assessment to recursive call attack vulnerabilities of the smart contract according to a reputation of both the one or more blockchain nodes and the one or more execution nodes.
