Smart contract of a blockchain for management of cryptocurrencies

A method of cybersecurity of a distributed smart contract executing on a blockchain using at least one hardware processor of a network connected server executing a code of the distributed smart contract of a distributed ledger dataset, for:

• managing a primary reserve of a plurality of primary tokens of a primary cryptocurrency and a secondary reserve of a plurality of secondary tokens of a secondary cryptocurrency;
• receiving a transaction request for the primary token;
• establishing communication with at least one server executing a code implementation of a price oracle configured to provide in real time an external price of the primary token, and accessing the price oracle to obtain the external price of the primary token;
• computing an updated total value of the primary reserve according to the external price provide by the price oracle;
• in response to the updated total value of primary reserve computed based on the price oracle being unequal to an initial staked value of the primary reserve, adjust a primary dynamic reserve weight and adjust a secondary dynamic reserve weight, 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;
• wherein the price oracle being monitored for detecting at least one of a failure and restoration thereof in providing the external price of the primary token.

A computer program product for cybersecurity of a distributed smart contract executing on a blockchain, comprising:

• a non-transitory memory storing thereon code for execution by at least one hardware process, the code including instructions for:
• managing a primary reserve of a plurality of primary tokens of a primary cryptocurrency and a secondary reserve of a plurality of secondary tokens of a secondary cryptocurrency;
• receiving a transaction request for the primary token;
• establishing communication with at least one server executing a code implementation of a price oracle configured to provide in real time an external price of the primary token, and accessing the price oracle to obtain the external price of the primary token;
• computing an updated total value of the primary reserve according to the external price provide by the price oracle;
• in response to the updated total value of primary reserve computed based on the price oracle being unequal to an initial staked value of the primary reserve, adjust a primary dynamic reserve weight and adjust a secondary dynamic reserve weight, 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;
• wherein the price oracle being monitored for detecting at least one of a failure and restoration thereof in providing the external price of the primary token.
