Abstract

A system may facilitate a distributed ledger technology (DLT) record based (for example, blockchain-based) ballot organization. A node configured to support an organizer role may generate a ballot that designates answers, and in some cases, conditions for valid vote-value transfers. The organizer may distribute vote-value to one or more voters. The voters may then commit portions (including null portions) of the received vote value to answers using committed tokens configured to bind the voter to a particular vote-value without divulging the particular vote value while in a cryptographic form.

Claims (69)

1. A cryptographic voting organization method including:

generating a ballot with an answer,

the answer including an answer identifier configured to:

direct reception of a committed token including a committed vote-value transferred from a voter,

the committed token configured to bind the voter to the committed vote-value without revealing the committed vote-value while in an cryptographic form, and

the committed vote-value including a null or at least a portion of a voter vote-value;

initiating establishment of the ballot on a ledger;

determining a vote-value distribution;

requesting a transaction,

the transaction transferring a voter token to a voter identifier of the voter, and

the voter token conferring the voter vote-value to the voter; and

accounting for the transaction by causing a recordation of the voter vote-value on the ledger.

2. The cryptographic voting organization method of claim 1 , where requesting the transaction further includes:

requesting that the transaction send a rest token back to an organizer, and

the rest token including a remainder vote-value corresponding to an initial vote-value with at least the voter vote-value deducted.

3. The cryptographic voting organization method of claim 1 , where generating the ballot includes generating a ballot allowing non-integer vote-value transfers.

4. The cryptographic voting organization method of claim 1 , where generating the ballot includes designating an allowed range for vote-value transfers for the ballot.

5. The cryptographic voting organization method of claim 1 , where generating the ballot includes designating a public key to serve as the answer identifier.

6. The cryptographic voting organization method of claim 1 , where generating the ballot includes designating a public key to serve as the voter identifier.

7. The cryptographic voting organization method of claim 6 , where a structure for the transaction includes:

the voter token;

an amount field designating the voter vote-value, the amount field encrypted with the public key; and

a blinding field designating a blinding factor used to obfuscate the amount field, the blinding field encrypted with the public key.

8. The cryptographic voting organization method of claim 1 , where:

the ledger includes a blockchain; and

establishing the ballot includes:

causing the ballot to be recorded on the blockchain; and

designating a public key to serve as an organizer identifier.

9. The cryptographic voting organization method of claim 1 , generating a ballot further includes:

designating multiple points on an elliptic curve for generation of token for transferring vote-value, the multiple points including:

an amount point; and

a blinding point.

10. The cryptographic voting organization method of claim 9 , where:

designating an amount point includes:

designating a cryptographic key to apply to a curve generation function for the elliptic curve; and

designating a blinding point includes:

designating a hash function to apply to the amount point to generate the blinding point.

11. A cryptographic voting organization system including:

memory configured to store a ledger; and

ballot organization circuitry in data communication with the memory, the ballot organization circuitry configured to:

generate a ballot with an answer, the answer including an answer identifier configured to:

direct reception of a committed token including a committed vote-value transferred from a voter, the committed token configured to bind the voter to the committed vote-value without revealing the committed vote-value while in a cryptographic form, the committed vote-value including a null or at least a portion of a voter vote-value;

initiate establishment of the ballot on the ledger;

determine a vote-value distribution;

request a transaction transferring a voter token to a voter identifier of the voter, the voter token conferring the voter vote-value to the voter; and

account for the transaction by causing a recordation of the voter vote-value on the ledger.

12. The cryptographic voting organization system of claim 11 , where the ballot organization circuitry is further configured to generate the ballot by generating a ballot allowing non-integer vote-value transfers.

13. The cryptographic voting organization system of claim 11 , where the ballot organization circuitry is further configured to generate the ballot by designating an allowed range for vote-value transfers for the ballot.

14. The cryptographic voting organization system of claim 11 , where the ballot organization circuitry is further configured to generate the ballot by designating a public key to serve as the answer identifier.

15. The cryptographic voting organization system of claim 11 , where generating the ballot includes designating a public key to serve as the voter identifier.

16. The cryptographic voting organization system of claim 15 , where the ballot organization circuitry is further configured to generate the ballot by designating a structure for the transaction, the structure including:

the voter token;

an amount field designating the voter vote-value, the amount field encrypted with the public key; and

a blinding field designating a blinding factor used to obfuscate the amount field, the blinding field encrypted with the public key.

17. A product including:

non-transitory machine-readable media; and

instructions stored on the non-transitory machine-readable media, the instructions configured to, when executed, cause a machine to:

generate a ballot with an answer, the answer including an answer identifier configured to:

direct reception of a committed token including a committed vote-value transferred from a voter, the committed token configured to bind the voter to the committed vote-value without revealing the committed vote-value while in a cryptographic form, the committed vote-value including a null or at least a portion of a voter vote-value;

cause establishment of the ballot on a ledger;

determine a vote-value distribution;

request a transaction transferring a voter token to a voter identifier of the voter, the voter token conferring the voter vote-value to the voter; and

account for the transaction by causing recordation of the voter vote-value on the ledger.

18. The product of claim 17 , the instructions are further configured to cause the machine to generate a ballot further by designating multiple points on an elliptic curve for generation of token for transferring vote-value, the multiple points including:

an amount point; and

a blinding point.

19. The product of claim 18 , the instructions are further configured to cause the machine to:

designate an amount point by designating a cryptographic key to apply to a curve generation function for the elliptic curve; and

designate a blinding point by designating a hash function to apply to the amount point to generate the blinding point.
