SECURITY GATEWAY FOR HIGH SECURITY BLOCKCHAIN SYSTEMS

1 . A system for providing security blockchain systems where at least some users are on insecure networks, comprising:

a security gateway comprising at least a processor and a memory, at least two communications ports, and a plurality of programming instructions stored in the memory and operable on the processor, wherein the plurality of programming instructions, when operating on the processor, cause the processor to:

inspect requests for compliance using a rules engine according to a plurality of rules; and

pass compliant requests to their respective intended destinations;

wherein compliance inspection comprises at least checking credentials of a sender of each request;

wherein a request comprises one or more smart contracts; and

wherein a transaction resulting from a request is blocked if it would result in an asset transfer to a non-whitelisted address on an insecure network.

2 . The system of claim 1 , wherein before proceeding with permitting a transaction resulting from a request, the security gateway obtains permission from an entity, and only allows an asset transfer to a non-whitelisted address on an insecure network upon receiving the correct credentials from the entity, would the gateway allow the asset transfers to a non-whitelisted address on the not secure side of the network.

3 . The system of claim 2 , wherein credentials are further required for asset transfers to whitelisted addresses.

4 . A method for providing security blockchain systems where at least some users are on insecure networks, comprising:

inspecting, at a security gateway, requests for compliance using a rules engine according to a plurality of rules;

passing compliant requests to their respective intended destinations;

checking credentials of a sender of each request; and

blocking a transaction resulting from a request if it would result in an asset transfer to a non-whitelisted address on an insecure network;

wherein a request comprises one or more smart contracts.

5 . The method of claim 4 , wherein before proceeding with permitting a transaction resulting from a request, the security gateway obtains permission from an entity, and only allows an asset transfer to a non-whitelisted address on an insecure network upon receiving the correct credentials from the entity, would the gateway allow the asset transfers to a non-whitelisted address on the not secure side of the network.

6 . The method of claim 5 , wherein credentials are further required for asset transfers to whitelisted addresses.
