Abstract

Digital or “smart” contracts execute in a blockchain environment. Any entity (whether public or private) may specify a digital contract via a contract identifier in a blockchain. Because there may be many digital contracts offered as virtual services, the contract identifier uniquely identifies a particular digital contract offered by a virtual machine, vendor or supplier. The blockchain is thus not burdened with the programming code that is required to execute the digital contract. The blockchain need only include or specify the contract identifier (and perhaps one or more contractual parameters), thus greatly simplifying the blockchain and reducing its size (in bytes) and processing requirements.

First claim

The invention claimed is:

1. A method performed by a server that reduces a memory byte size consumed by a blockchain stored to a solid-state memory device, the method comprising:
receiving, by the server, the blockchain recording transactions conducted by computers via a network;
storing, by the server, the blockchain to the solid-state memory device;
identifying, by the server, a contract identifier specified by the blockchain in lieu of a programming code representing a smart contract;
identifying, by the server, a network address by querying an electronic database that associates the contract identifier specified by the blockchain to the network address;
sending, by the server, a service request via the network to the network address requesting a software service associated with the contract identifier; and
generating, by the server, a data record in a blockchain data layer describing the service request sent via the network to the network address requesting the software service associated with the contract identifier;
wherein the contract identifier specified by the blockchain reduces the memory byte size consumed by the blockchain stored to the solid-state memory device.

2. The method of claim 1 , further comprising receiving a service result of the software service.

3. The method of claim 2 , further comprising generating another data record in the blockchain data layer that describes the service result of the software service.

4. The method of claim 2 , further comprising transacting a cryptocoinage in response to the service result.

5. The method of claim 1 , further comprising receiving a service update associated with the software service.

6. The method of claim 5 , further comprising generating another data record in the blockchain data layer that describes the service update associated with the software service.

7. The method of claim 1 , further comprising transacting a cryptocoinage in response to the generating of the data record in the blockchain data layer.

8. A server that reduces a memory byte size associated with a blockchain, comprising:
a hardware processor; and
a memory device storing instructions that, when executed by the hardware processor, perform operations, the operations comprising:
receiving the blockchain specifying a contract identifier associated with a smart contract;
identifying a network address by querying an electronic database for the contract identifier specified by the blockchain, the electronic database electronically associating network addresses to contract identifiers including the network address that is electronically associated with the contract identifier specified by the blockchain;
sending a service request to the network address identified by the querying of the electronic database, the service request requesting a software service associated with the contract identifier; and
generating a data record in a blockchain data layer that describes the service request requesting the software service associated with the contract identifier;
wherein the contract identifier associated with the smart contract reduces the memory byte size associated with the blockchain.

9. The system of claim 8 , wherein the operations further comprise receiving a service result of the software service.

10. The system of claim 9 , wherein the operations further comprise generating another data record in the blockchain data layer that describes the service result of the software service.

11. The system of claim 9 , wherein the operations further comprise transacting a cryptocoinage in response to the service result.

12. The system of claim 8 , wherein the operations further comprise receiving a service update associated with the software service.

13. The system of claim 12 , wherein the operations further comprise generating another data record in the blockchain data layer that describes the service update associated with the software service.

14. The system of claim 8 , wherein the operations further comprise transacting a cryptocoinage in response to the generating of the data record in the blockchain data layer.

15. A memory device storing instructions that when executed by a hardware processor perform operations that reduce a memory byte size associated with a blockchain, the operations comprising:
receiving the blockchain specifying a contract identifier associated with a smart contract;
identifying a network address by querying an electronic database for the contract identifier specified by the blockchain, the electronic database electronically associating network addresses to contract identifiers including the network address that is electronically associated with the contract identifier specified by the blockchain;
sending a service request to the network address identified by the querying of the electronic database, the service request requesting a software service associated with the contract identifier; and
generating a data record in a blockchain data layer that describes the service request requesting the software service associated with the contract identifier;
wherein the contract identifier associated with the smart contract reduces the memory byte size associated with the blockchain.

16. The memory device of claim 15 , wherein the operations further comprise receiving a service result of the software service.

17. The memory device of claim 16 , wherein the operations further comprise generating another data record in the blockchain data layer that describes the service result of the software service.

18. The memory device of claim 16 , wherein the operations further comprise transacting a cryptocoinage in response to the service result.

19. The memory device of claim 15 , wherein the operations further comprise receiving a service update associated with the software service.

20. The memory device of claim 19 , wherein the operations further comprise generating another data record in the blockchain data layer that describes the service update associated with the software service.
