There is provided a processor(s) executing a blockchain smart contract, for: managing a primary reserve of primary tokens and a secondary reserve of secondary tokens, receiving a transaction request, obtaining an external price of the primary token, compute an updated value of the primary reserve according to the external price, in response to the updated total value of primary reserve being unequal to an initial staked value of the primary reserve, adjust primary and secondary dynamic reserve weights, wherein a total value computed by a function of the primary reserve after being increased or decreased by a target amount of primary tokens and using the adjusted primary and secondary dynamic reserve weights, is equal to the initial staked value of the primary reserve, and the total value of the primary reserve is maintained at a predefined ratio to a total value of the secondary reserve, and executing the transaction request.

The present invention relates to a method and a system for inscribing and securely storing cryptographic keys on a physical medium, and to a corresponding physical medium, comprising the following steps: from a first management entity (31), generating (1) a first pair of asymmetric cryptographic keys comprising a first user public key (pub1) and a first user private key (priv1), inscribing (2) the first user private key (priv1) onto a physical medium, and affixing (4) a first tamper-evident concealing element (hol1) to the physical medium in order to conceal the first user private key (priv1) and seal same, said first user private key (priv1) being accessible only by visibly breaking said first tamper-evident concealing element (hol1); from the second management entity (32), generating (6) a second pair of asymmetric cryptographic keys comprising a second user public key (pub2) and a second user private key (priv2), inscribing (7) the second user private key (priv2) onto the physical medium and affixing (9) a second tamper-evident concealing element (hol2) to the physical medium in order to conceal the second user private key (priv2) and seal same, said second user private key (priv2) being accessible only by visibly breaking said second tamper-evident concealing element (hol2); generating (10) at least one last user public key (pub0) and/or at least one cryptographic address (adr, adr-mult) from the first user public key (pub1) and the second user public key (pub2), inscribing (11) said at least one last public user key (pub0) and/or said at least one cryptographic address (adr, adr-mult) onto the physical medium, and verifying (12, 13) same, and finally recovering the private keys (priv1, priv2) comprising the generation of a last user private key (priv0) corresponding to the last user public key (pub0) and/or to said at least one cryptographic address (adr, adr-mult).

Methods for providing decentralized product and rewards delivery platform are provided. The method includes: issuing, by an asset management unit, a number of fungible tokens according to a number of products related to the company in a predetermined period of time provided by the company; distributing the fungible tokens into wallets of users who purchase one of the products of the company from a platform; issuing drawing tickets to the wallets of the users who redeem the fungible tokens, where the drawing tickets are automatically entered into a rewards pool for drawing; drawing rewards in the rewards pool to determine winners from the users who have the drawing tickets, according to reward rules; and issuing the rewards using smart contracts and depositing the rewards into wallets of the winners. The winners redeem the rewards by claiming the drawing tickets in their wallets.

A method for enabling real-time authorization of a transaction with pooled equity includes: receiving a transaction request message, the transaction request message including at least a public key of a cryptographic key pair and a transacting currency amount; verifying a balance of a cryptographic currency for a first blockchain wallet associated with the cryptographic key pair on a blockchain using at least the public key, where at least a portion of the balance is locked in a currency pool; generating a smart contract, the smart contract configured to initiate a first blockchain transaction on the blockchain for transfer of the transacting currency amount from a second blockchain wallet to a destination address, where the second blockchain wallet is different from the first blockchain wallet; and transmitting the generated smart contract to a node in a blockchain network associated with the blockchain for publishing to the blockchain.

A method for digital coin issuance may include: receiving, at a ledger interoperability service and from a gateway communication service, a request to deposit a digital coin balance for an amount of funds for a client to a client digital coin wallet on a distributed ledger; receiving, at an omnibus account, a transfer of the funds from a client demand deposit account for the client; identifying, by the ledger interoperability service, an address for the client digital coin wallet on the distributed ledger using an address book; submitting, by the ledger interoperability service, a request to the gateway communication service to issue the digital coin balance to the client digital coin wallet and to generate postings for the digital coin balance for the distributed ledger; and receiving, by the ledger interoperability service, confirmation from gateway communication service of writing the digital coin balance to the client digital coin wallet.

A crypto ETP is administered by a portfolio modeling computer/(PMC), a fund administration computer/(FAC), an order taking platform computer/(OTP), a custodian computer/(CC), and a paying agent settlement computer/(PASC). The PMC defines the ETP and captures data for a cryptocurrency index. The CC tracks Underlying Assets held by the ETP, and sends the data to the FAC, which calculates the NAV of the Underlying Assets to generate a Portfolio Composite File/(PCF) sent to the OTP. The OTP receives and validates/confirms with the CC, orders for creations and redemptions of the ETP from Authorized Parties/(APs), in exchange for the Underlying Assets and/or cryptocurrency. The PASC provides settlement on the Exchange in cryptocurrency by: receiving confirmation from the CC of transfer of underlyings, ETPs or cryptocurrency from the APs to a blockchain wallet associated with the PCM; and issuing units of the ETPs, underlyings or cryptocurrency to the APs.

In one aspect, a computer system useful for implementing a blockchain-based digital payments and money transfer application provides blockchain-based digital payments and money transfer application; provide a creates a blockchain-based digital cash account; enables a user to download a blockchain-based digital cash account application from an online mobile store using the blockchain-based digital cash application; enables a user to download the blockchain-based digital cash account on the user's mobile device and open the blockchain-based digital cash account; enable the user to then tap a profile logo; sends a one-time password (OTP) to a registered mobile number of the user; and enables the user to enter the one-time password (OTP) into the blockchain-based digital cash application.

Embodiments provide for managing ownership of physical objects and digital counterparts using a distributed ledger and tokens stored on the physical objects. An example method generally includes reading, via a wireless data connection between a physical object and a mobile device, a token stored on the physical object. The token may include at least a unique identifier of the physical object. A request to transfer ownership of the physical object to an owner of the mobile device is generated, and the request may include at least the unique identifier of the physical object. The generated request is transmitted to a distributed ledger system, and a response is received from the distributed ledger system indicating whether the transfer was successful. The indication of whether the transfer was successful is displayed on the mobile device.

A method includes conveying a cryptocurrency transaction to a peer-to-peer network, wherein said cryptocurrency transaction having encoded therein an email address and to convey goods or services embodied in an electronic form to the email address in response to receipt of said cryptocurrency transaction on said peer-to-peer network. The conveying of goods or services includes transmitting over the Internet in conformance with an email protocol. The goods or services includes event admission tickets, music recordings, video, text, game content, live event broadcast, software, encryption keys or passwords.
