Methods and systems for forensic investigations in contract networks

A system for blockchain value transfers comprising:

• means for receiving a plurality of transaction requests, each transaction request comprising:
• a sending user account address on a first blockchain network;
• a receiving user account address on a second blockchain network;
• a transaction value expressed in terms of a quantity of first in-network tokens;
• and
• an API request;
• means for performing a balance check procedure on each transaction request comprising:
• identifying a present permitted transaction amount in first in-network tokens for the sending user account address;
• determining if the transaction value in first in-network tokens is greater than the present permitted transaction amount of the sending user account address;
• upon determining the transaction value in first in-network tokens is greater than the present permitted transaction amount in first in-network tokens of the sending user account address, refusing the transaction;
• upon determining the transaction value is not greater than the present permitted transaction amount of the sending user account address, adding the transaction request to an aggregate transaction record;
• updating the present permitted transaction amount of the sending user account address reflecting a debit of the transaction value;
• and
• updating the present permitted transaction amount of the receiving user account address reflecting a credit of the transaction value;
• and
• means for initiating a transaction comprising calculating a net transaction amount;
• wherein the means for initiating the transaction comprising calculating the net transaction amount is operable to execute each of a GET command, a SEND command, an XSEND command, a REQUEST command, an XREQUEST command, a RESPOND command, an XRESPOND command, and a SIGN command;
• and
• wherein the first blockchain network and the second blockchain network may be the same blockchain network or different blockchain networks.

A blockchain value transfer method performed by a server comprising:

• receiving at the server a plurality of transaction requests, each transaction request comprising:
• a sending user account address on a first blockchain network;
• a receiving user account address on a second blockchain network;
• a transaction value expressed in terms of a quantity of first in-network tokens;
• and
• an API request;
• performing by the server a balance check procedure on each transaction request comprising:
• identifying a present permitted transaction amount in first in-network tokens for the sending user account address;
• determining if the transaction value in first in-network tokens is greater than the present permitted transaction amount of the sending user account address;
• upon determining the transaction value in first in-network tokens is greater than the present permitted transaction amount in first in-network tokens of the sending user account address, refusing the transaction;
• upon determining the transaction value is not greater than the present permitted transaction amount of the sending user account address, adding the transaction request to an aggregate transaction record;
• updating the present permitted transaction amount of the sending user account address reflecting a debit of the transaction value;
• and
• updating the present permitted transaction amount of the receiving user account address reflecting a credit of the transaction value;
• and
• initiating a transaction comprising calculating a net transaction amount;
• wherein the server is operable to execute each of a GET command, a SEND command, an XSEND command, a REQUEST command, an XREQUEST command, a RESPOND command, an XRESPOND command, and a SIGN command;
• and
• wherein the first blockchain network and the second blockchain network may be the same blockchain network or different blockchain networks.
