the virtual machine oracle including at least one interface enabling the at least one smart contract to log into the virtual machine oracle,

the virtual machine oracle configured to handle conflict resolution of blockchain transactions by:

tracking at least one pending blockchain transaction, the at least one pending blockchain transaction having been executed, but not yet committed, on a corresponding blockchain;

identifying an unexecuted blockchain transaction for cryptocurrency exchange that does not have bond backing;

verifying whether the identified unexecuted blockchain transaction is configured with bond backing; and

responsive to verifying that the identified unexecuted blockchain transaction is configured without bond backing:

determining whether the identified unexecuted blockchain transaction is valid or invalid as a function of transaction information associated with the identified unexecuted blockchain transaction and the at least one pending blockchain transaction;

verifying the identified unexecuted blockchain transaction is associated with an unaltered digital wallet executing in a trusted execution environment (TEE) or trusted platform module (TPM); and

outputting a result, the result indicating whether the identified unexecuted blockchain transaction was determined to be valid or invalid.

2. The system of claim 1 , wherein the at least one pending blockchain transaction includes at least one pending cross-chain blockchain transaction, at least one sidechain blockchain transaction, or a combination thereof.

3. The system of claim 1 , wherein the transaction information associated with the at least one pending blockchain transaction includes data from the corresponding blockchain, a sidechain of the corresponding blockchain, at least one other blockchain, at least one sidechain of the at least one other blockchain, or a combination thereof.

4. The system of claim 1 , wherein the virtual machine oracle is further configured to determine whether the identified unexecuted blockchain transaction is valid or invalid and output the result in response to receiving the identified unexecuted blockchain transaction from a smart contract executed on the corresponding blockchain.

5. The system of claim 4 , wherein to output the result, the virtual machine oracle is further configured to send the result to the smart contract.

6. The system of claim 1 , wherein to determine whether the identified unexecuted blockchain transaction is valid or invalid, the virtual machine oracle is further configured to determine whether a conflict exists between the unexecuted blockchain transaction and the at least one pending blockchain transaction, wherein the identified unexecuted blockchain transaction is determined to be valid based on determining that the conflict does not exist, and wherein determining that the identified unexecuted blockchain transaction is invalid is based on determining that the conflict does exist.

7. The system of claim 6 , wherein the virtual machine oracle is further configured to:

compute an account balance based on the transaction information; and

determine whether the conflict exists based on the account balance computed.

8. The system of claim 6 , wherein, in an event the account balance is computed to be negative, the virtual machine oracle is further configured to determine that the conflict does exist, and wherein, in an event the account balance is computed to be positive, the virtual machine oracle is further configured to determine that the conflict does not exist.

9. The system of claim 1 , wherein the identified unexecuted blockchain transaction is initiated by a user and wherein the transaction information is associated with the user or a wallet address of a digital wallet owned by the user.

10. The system of claim 1 , wherein the identified unexecuted blockchain transaction is initiated by a user and wherein the transaction information includes know your customer (KYC) information associated with the user.

11. The system of claim 1 , wherein the virtual machine oracle is further configured to:

store the at least one pending blockchain transaction in a queue; and

remove the at least one pending blockchain transaction from the queue, in an event the at least one pending blockchain transaction is committed on the corresponding blockchain or removed from the corresponding blockchain.

12. A computer-implemented method for blockchain cryptocurrency exchange, the computer-implemented method comprising, by one or more processors of one or more computing nodes:

implementing a trusted bondless cryptocurrency exchange without bond backing by, via a virtual machine oracle, the virtual machine oracle being accessible to at least one smart contract, the virtual machine oracle including at least one interface enabling the at least one smart contract to log into the virtual machine oracle:

tracking at least one pending blockchain transaction on a corresponding blockchain, the at least one pending blockchain transaction having been executed, but not yet committed, on the corresponding blockchain;

identifying an unexecuted blockchain transaction for cryptocurrency exchange that does not have bond backing;

verifying whether the identified unexecuted blockchain transaction is configured with bond backing; and

responsive to verifying that the identified unexecuted blockchain transaction is configured without bond backing:

determining whether the identified unexecuted blockchain transaction is valid or invalid as a function of transaction information associated with the identified unexecuted blockchain transaction and the at least one pending blockchain transaction;

verifying the identified unexecuted blockchain transaction is associated with an unaltered digital wallet executing in a trusted execution environment (TEE) or trusted platform module (TPM); and

outputting a result of the determining, the result indicating whether the identified unexecuted blockchain transaction was determined to be valid or invalid.

13. The method of claim 12 , wherein the at least one pending blockchain transaction includes at least one pending cross-chain blockchain transaction, at least one sidechain blockchain transaction, or a combination thereof.

14. The method of claim 12 , wherein the transaction information associated with the at least one pending blockchain transaction includes data from the corresponding blockchain, a sidechain of the corresponding blockchain, at least one other blockchain, at least one sidechain of the at least one other blockchain, or a combination thereof.

15. The method of claim 12 , further comprising, via the virtual machine oracle, receiving the identified unexecuted blockchain transaction from a smart contract executed on the corresponding blockchain, and wherein the determining and outputting are performed in response to the receiving.

16. The method of claim 15 , wherein the outputting includes sending the result to the smart contract.

17. The method of claim 12 , wherein the determining includes determining whether a conflict exists between the identified unexecuted blockchain transaction and the at least one pending blockchain transaction, and wherein the identified unexecuted blockchain transaction is determined to be valid based on determining that the conflict does not exist, and wherein determining that the identified unexecuted blockchain transaction is invalid is based on determining that the conflict does exist.

18. The method of claim 17 , further comprising, via the virtual machine oracle, computing an account balance based on the transaction information, and wherein determining whether the conflict exists is based on the account balance computed.

19. The method of claim 17 , wherein, in an event the account balance is computed to be negative, the conflict is determined to exist, and wherein, in an event the account balance is computed to be positive, the conflict is determined not to exist.

20. The method of claim 12 , further comprising, via the virtual machine oracle, initiating the identified unexecuted blockchain transaction on behalf of a user, and wherein the transaction information is associated with the user or a wallet address of a digital wallet owned by the user.

21. The method of claim 12 , further comprising, via the virtual machine oracle, initiating the identified unexecuted blockchain transaction on behalf of a user, and wherein the transaction information includes know your customer (KYC) information associated with the user.
