Blockchain Architecture for Fiat-Denominated Smart Contract Execution via Oracle-Linked NAV

A method for redeeming cryptocurrency coins, the method comprising:

• a) calculating a first Net Asset Value (NAV) at a first time based on an asset value divided by a number of outstanding coins;
• b) providing the first NAV to a decentralized blockchain via an oracle interface, wherein the oracle interface is configured to make the first NAV accessible to smart contracts on the decentralized blockchain;
• c) receiving at a second time after the first time, from a holder, a request to redeem the cryptocurrency coins, the request specifying a fiat-denominated redemption amount and a holder wallet address;
• d) waiting until a third time that is after the second time to calculate a second NAV based on an updated asset value divided by an updated number of outstanding coins;
• e) providing the second NAV to the decentralized blockchain via the oracle interface;
• f) waiting until after the third time to submit a transaction request to a smart contract operating on the decentralized blockchain, the request identifying the holder wallet address and a fiat-denominated transaction amount;
• g) receiving, by the smart contract, the second NAV from the oracle interface on the decentralized blockchain;
• h) calculating, by the smart contract, a number of coins by dividing the fiat-denominated transaction amount by the second NAV;
• i) transferring, by the smart contract, the number of coins from the holder wallet address by updating coin balance associated with the holder wallet address and emitting a transfer event on the decentralized blockchain;
• j) transferring the fiat-denominated redemption amount to the holder;
• and
• k) burning the number of coins.

A method for transferring cryptocurrency coins in a transaction between a sender and a recipient, the method comprising:

• a) calculating a Net Asset Value (NAV) based on an asset value for financial assets minus liabilities, divided by a number of outstanding coins;
• b) providing the NAV to a decentralized blockchain via an oracle interface, wherein the oracle interface is configured to make the NAV accessible to smart contracts on the decentralized blockchain;
• c) receiving a transaction request at a smart contract operating on the decentralized blockchain, the transaction request identifying these transaction parameters:
• i) a sender wallet address,
• ii) a recipient wallet address, and
• iii) a fiat-denominated transaction amount;
• d) receiving, by the smart contract, the NAV from the oracle interface;
• e) calculating, by the smart contract, a number of coins by dividing the fiat-denominated transaction amount by the NAV;
• and
• f) transferring, by the smart contract, the number of coins by updating a coin balance at the sender wallet address and the recipient wallet address and emitting a transfer event on the decentralized blockchain.
