A method for securing an interblockchain transaction includes receiving, from a first user application, a registration request including a first permissioned blockchain public key and a first permissionless blockchain public key. The method also includes performing, by the processing circuitry, receiving, from a second user application, a second registration request including a second permissioned blockchain public key and a second permissionless blockchain public key. The permissioned blockchain public keys are valid on the permissioned blockchain and the permissionless blockchain public keys are valid on the permissionless public blockchain. In addition, the method includes receiving, from the first user application, a transaction identification, the transaction identification identifying a first transfer transaction executed on the permissionless public blockchain. The transaction identification identifies the first and second permissionless blockchain public keys.

A diamond asset comprising one or more diamonds and an encryption chip is used to asset-back a cryptographic token that can be used to conduct transactions. The cryptographic token is written to a blockchain using a smart contract that is configured to enable a transaction associated with the token in response to two or more of: a signature by the encryption chip, a signature by the owner of the diamond asset, and a validation of a visual layout of the diamond asset.

A transaction device is described. The device comprises storage configured to store a first data record comprising first value data and a unique identifier associated with one other device; communications circuitry configured to receive an identifier and second value data from a device; and control circuitry configured to compare the received identifier with the unique identifier and in the event of a positive comparison, the control circuitry is further configured to update the stored first value data in accordance with the exchanged second value data.

A distributed cryptocurrency smart order router (DCCSOR) is disclosed, which allows clients to keep control of their own private and exchange keys to their wallets and accounts, but can execute orders across multiple exchanges simultaneously.

Systems and methods are disclosed for automating digital asset transfers based on historical transactions. In one implementation, a notification corresponding to a first transaction or operation associated with a first entity is received. Based on the notification, a second transaction or operation is initiated with respect to one or more digital tokens. One or more digital tokens are received in response to the second transaction. At least one of the one or more digital tokens, as secured via one or more cryptographic keys, is stored in a wallet associated with the first entity.

An integration system for a system of platforms includes an orchestration platform, a blockchain transactional platform, a digital transactional platform, a merchant system, a user trust platform, and one or more user devices connected to each other and a distributed ledger and/or a secondary mesh network via one or more networks. The blockchain transactional platform performs accesses and performs actions on the distributed ledger and/or the secondary mesh network. The digital transactional platform maintains transactional data indicative of an amount of first-domain value correlated to a user. The blockchain transactional platform maintains blockchain transactional data indicative of an amount of second-domain value correlated to the user. The orchestration platform manages data exchange, synthesis, fusion, analysis, and transformation between the components of the system, including for the orchestration of transactions.

The technology teaches a distributed gaming system, comprising a server-side node configured to administer transactions for a gambling casino, selling and redeeming chips using a private database, and recording transactions on a distributed ledger using crypto-tokens for a house account, with a token vault wallet that has a unique identifier and private key to track transactions. Customer wallets, intermediary accounts and one-way redemption wallets track transactions on the distributed ledger. Client-side nodes accept token purchase messages and transfer tokens in the ledger and record in the database, accept token-to-chip messages from an intermediary account and transfer tokens on the ledger to the redemption wallet to extinguish and record the exchange, accept chip-to-token messages from an intermediary account and transfer tokens from the vault to the customer account and record the exchange, and accept token-to-fiat messages from an intermediary account and transfer tokens to extinguish, and record the exchange.

Methods, systems, and apparatuses for block chain security schemes for electronic cash tokens are described herein.

Various aspects of the disclosure relate to using a verifiable and distributed encoding as a digital currency (e.g., cryptocurrency). According to some embodiments, systems and methods can be executed to transfer cash or “hard” currency responsive to exchange of cryptocurrency supported by blockchain technology. In further example, the systems and methods are tailored to operate within a specified/defined community that ensures the efficient operation of the system by ensuring liquidity of the transfer. According to one embodiment, the system is configured to distribute stable coin, issuing the coin at a discounted value (e.g., relative to a redemption or cash equivalent face value). For example, by issuing coin at a discount the system automatically facilitates peer-to-peer physical cash transfers.
