1. A method comprising: (9) (4)

(a) obtaining a first instruction comprising a first leg specifying a first counterparty and a second counterparty that are counterparties to a first transaction and an amount of a first asset owned by the first counterparty;

(b) confirming that the first instruction is authorized, wherein confirming that the first instruction is authorized comprises locking the first asset in response to obtaining confirmation without transferring the first asset;

(c) executing the first instruction after the first instruction is confirmed to be authorized, wherein executing the first instruction comprises transferring the first asset from the first counterparty to the second counterparty; and

(d) recording in a blockchain that the first instruction has been executed.

2. The method of claim 1, wherein: (2) (3)

(a) the first instruction further comprises a second leg specifying the first counterparty, the second counterparty, and an amount of a second asset owned by the second counterparty to be transferred to the first counterparty in exchange for the first asset;

(b) confirming that the first instruction is authorized further comprises locking the second asset in response to obtaining confirmation without transferring the second asset; and

(c) executing the first instruction after the first instruction is confirmed to be authorized further comprises transferring the second asset from the second counterparty to the first counterparty.

3. The method of claim 2, wherein confirming that the first instruction is authorized comprises receiving confirmation from the first and second counterparty systems after the instruction is obtained that the first instruction is authorized. (0)

4. The method of claim 2, wherein locking the second asset comprises recording in the blockchain that the second asset is locked. (0)

5. The method of claim 1, wherein obtaining the first instruction, confirming that the first instruction is authorized, and executing the first instruction are performed using computer program code that implements a protocol layer of the blockchain. (0)

6. The method of claim 1, further comprising generating an instruction generator before obtaining the first instruction, wherein the instruction generator generates the first instruction. (1) (0)

7. The method of claim 6, wherein the first asset is issued by an issuer, and further comprising: (1) (2)

(a) prior to generating the instruction generator comprising the first instruction: (i) receiving a message from an exchange system to generate the instruction generator; and

(ii) receiving a message from an issuer system granting the instruction generator permission to generate instructions to transfer the first asset; and

(b) recording in the blockchain that the instruction generator has permission to generate the instructions to transfer the first asset.

8. The method of claim 7, further comprising: (1) (2)

10. The method of claim 1, wherein locking the first asset comprises recording in the blockchain that the first asset is locked. (0)

11. The method of claim 1, further comprising: (1) (4)

(a) obtaining a second instruction that comprises a second leg specifying a third counterparty and a fourth counterparty that are counterparties to a second transaction and an amount of a second asset owned by the third counterparty;

(b) confirming that the second instruction is authorized, wherein confirming that the second instruction is authorized comprises locking the second asset in response to obtaining confirmation from the third counterparty system without transferring the second asset;

(c) executing the second instruction after the third and fourth counterparty systems confirm that the second instruction is authorized, wherein executing the second instruction comprises transferring the second asset from the third counterparty to the fourth counterparty; and

(d) recording in the blockchain that the second instruction has been executed.

13. The method of claim 11, wherein at least one of the counterparties of the first transaction is also at least one of the counterparties of the second transaction. (0)

12. The method of claim 1, further comprising: (0) (3)

14. The method of claim 1, wherein: (0) (3)

(a) the first instruction further comprises one or more additional legs that collectively specify one or more additional counterparties to the first transaction and amounts of one or more additional assets to be transferred between the counterparties to the first transaction;

(b) the method further comprises confirming with one or more additional counterparty systems that the first instruction is authorized, wherein confirming with the one or more additional counterparty systems that the first instruction is authorized comprises locking the one or more additional assets in response to obtaining confirming from the one or more additional counterparty systems without transferring the one or more additional assets; and

(c) executing the first instruction comprises: (i) determining a net amount of the assets to be transferred between the counterparties, wherein determining the net amount comprises setting off amounts owed between the counterparties against each other; and

(ii) transferring the net amount between the counterparties.

15. The method of claim 1, wherein the first instruction automatically executes upon the blockchain achieving a certain block height. (0)

16. The method of claim 1, wherein an agent acts on behalf of at least one of the counterparties. (0)

17. A system comprising multiple servers networked together to form a blockchain, wherein each of the servers comprises: (1) (3)

(a) network interface hardware for interfacing with the other servers;

(b) a non-transitory computer readable medium; and

(c) a processor communicatively coupled to the network interface hardware and the non-transitory computer readable medium, wherein the non-transitory computer readable medium has stored thereon computer program code that is executable by the processor and that, when executed by the processor, causes the processor to perform a method comprising: (i) obtaining a first instruction comprising a first leg specifying a first counterparty and a second counterparty that are counterparties to a first transaction and an amount of a first asset owned by the first counterparty;

(ii) confirming that the first instruction is authorized, wherein confirming that the first instruction is authorized comprises locking the first asset in response to obtaining confirmation without transferring the first asset;

(iii) executing the first instruction after the first instruction is confirmed to be authorized, wherein executing the first instruction comprises transferring the first asset from the first counterparty to the second counterparty; and

(iv) recording in a blockchain that the first instruction has been executed.

18. The system of claim 17, wherein: (1) (3)

(b) confirming that the first instruction is authorized further comprises locking the second asset in response to obtaining confirmation without transferring the second asset; and

(c) executing the first instruction after the first instruction is confirmed to be authorized further comprises transferring the second asset from the second counterparty to the first counterparty.

19. The system of claim 18, wherein confirming that the first instruction is authorized comprises receiving confirmation from the first and second counterparty systems after the instruction is obtained that the first instruction is authorized. (0)

20. A non-transitory computer readable medium having stored thereon computer program code that is executable by a processor and that, when executed by the processor, causes the processor to perform a method comprising: (0) (4)

(d) recording in a blockchain that the first instruction has been executed.
