Abstract

Claims (71)

1 . A method for securely accessing resources across global or cloud computer networks, the method comprising:

receiving a first request, at a first token-specific self-executing program, to perform a first blockchain action using a first resource, wherein the first blockchain action is encoded in the first token-specific self-executing program, and wherein the first token-specific self-executing program identifies a first token;

determining, at the first token-specific self-executing program, a first condition for performing the first blockchain action, wherein the first condition is encoded in the first token-specific self-executing program, and wherein the first condition indicates a fraction of the first token to be transferred;

receiving, by the first token-specific self-executing program, a first availability of the first token corresponding to the first resource from a first blockchain network;

determining, by the first token-specific self-executing program, whether to perform the first blockchain action based on comparing the first condition to the first availability to determine that the first availability corresponds to the fraction; and

executing the first blockchain action, by the first token-specific self-executing program, based on determining to perform the first blockchain action, wherein executing the first blockchain action causes a first portion of the first token corresponding to the fraction to be transferred to a second resource.

2 . The method of claim 1 , wherein determining whether to perform the first blockchain action based on comparing the first condition to the first availability further comprises:

determining the first request corresponds to the first portion; and

determining whether the first availability corresponds to the first portion.

3 . The method of claim 1 , wherein executing the first blockchain action further comprises:

determining a second portion of the first token remaining at the first resource; and

determining a second availability of the first token corresponding to the first resource based on the second portion.

4 . The method of claim 1 , wherein executing the first blockchain action further comprises:

determining whether the second resource corresponds to a liquidity pool for the first blockchain network; and

determining to execute the first blockchain action based on determining that the second resource corresponds to the liquidity pool for the first blockchain network.

5 . The method of claim 1 , wherein encoding the first blockchain action in the first token-specific self-executing program further comprises:

receiving the first resource as a first statement in the first token-specific self-executing program; and

receiving a first logic in the first token-specific self-executing program that determines the second resource upon execution of the first token-specific self-executing program.

6 . The method of claim 1 , wherein encoding the first blockchain action in the first token-specific self-executing program further comprises:

receiving a first value for satisfying the first condition; and

receiving a first time for satisfying a second condition.

7 . The method of claim 1 , wherein determining whether to perform the first blockchain action is further based on:

transmitting a second user request to complete a first off-chain action; and

determining that the first off-chain action is completed.

8 . The method of claim 1 , wherein determining the first condition comprises determining a first requirement for a first cryptographically secure digital asset as recorded in a predetermined digital log corresponding to the first resource.

9 . The method of claim 1 , wherein determining whether to perform the first blockchain action is further based on:

determining a first tokenized availability for the first resource based on the first availability; and

determining that the first condition corresponds to the first tokenized availability.

10 . The method of claim 1 , wherein receiving the first request further comprises:

receiving, at a platform management application, a user request to perform a first off-chain action; and

determining that the first blockchain action corresponds to the first off-chain action.

11 . The method of claim 1 , wherein receiving the first request further comprises:

receiving, at a platform management application, a user request to perform a first off-chain action; and

determining that the first off-chain action corresponds to the second resource.

12 . The method of claim 1 , further comprising:

determining a first cryptographically secure digital asset corresponding to the first token; and

recording the first cryptographically secure digital asset in a first digital log for the first resource.

13 . The method of claim 12 , wherein executing the first blockchain action based on determining to perform the first blockchain action further comprises:

recording the first cryptographically secure digital asset in a second digital log for the second resource;

determining a second availability for the second resource based on the first cryptographically secure digital asset; and

transmitting a second verification that the second resource has the second availability.

14 . The method of claim 12 , further comprising:

determining a first characteristic of the first token; and

selecting the first cryptographically secure digital asset, from a plurality of cryptographically secure digital assets, based on the first characteristic.

15 . The method of claim 12 , further comprising:

determining a second condition for performing the first blockchain action; and

selecting the first cryptographically secure digital asset, from a plurality of cryptographically secure digital assets, based on the second condition.

16 . One or more non-transitory, computer-readable mediums comprising instructions recorded thereon that when executed by one or more processors cause operations comprising:

receiving a first request, at a first token-specific self-executing program, to perform a first blockchain action using a first resource, wherein the first blockchain action is encoded in the first token-specific self-executing program, and wherein the first token-specific self-executing program identifies a first token;

determining, at the first token-specific self-executing program, a first condition for performing the first blockchain action, wherein the first condition is encoded in the first token-specific self-executing program, and wherein the first condition indicates a fraction of the first token to be transferred;

receiving, by the first token-specific self-executing program, a first availability of the first token corresponding to the first resource from a first blockchain network;

determining, by the first token-specific self-executing program, whether to perform the first blockchain action based on comparing the first condition to the first availability to determine that the first availability corresponds to the fraction; and

executing the first blockchain action, by the first token-specific self-executing program, based on determining to perform the first blockchain action, wherein executing the first blockchain action causes a first portion of the first token corresponding to the fraction to be transferred to a second resource.

17 . The one or more non-transitory, computer-readable mediums of claim 16 , wherein encoding the first blockchain action in the first token-specific self-executing program further comprises:

receiving the first resource as a first statement in the first token-specific self-executing program; and

receiving a first logic in the first token-specific self-executing program that determines the second resource upon execution of the first token-specific self-executing program.

18 . The one or more non-transitory, computer-readable mediums of claim 16 , wherein encoding the first blockchain action in the first token-specific self-executing program further comprises:

receiving a first value for satisfying the first condition; and

receiving a first time for satisfying a second condition.

19 . A system for securely accessing resources across global or cloud computer networks, the system comprising:

one or more processors; and

one or more non-transitory, computer-readable mediums comprising instructions recorded thereon that when executed by the one or more processors cause operations comprising:

receiving, at a platform application, a first user request to perform a first off-chain action;

determining a first blockchain action that corresponds to the first off-chain action;

receiving a first request, at a first token-specific self-executing program, to perform the first blockchain action using a first resource, wherein the first blockchain action is encoded in the first token-specific self-executing program;

determining, at the first token-specific self-executing program, a first condition for performing the first blockchain action, wherein the first condition is encoded in the first token-specific self-executing program, and wherein the first condition indicates a fraction of first token to be transferred;
