US-12627670-B2 - Blockchain folding

Abstract

An active distributed ledger may comprise an indication of an inactive permission associated with a user device. An entry comprising such indication added to another distributed ledger that is supplemental to the active distributed ledger. An updated active distributed ledger may be generated that does not comprise the indication of the inactive permission. The updated active distributed ledger may comprise an indication of a new permission associated with the user device. The updated active distributed ledger may be stored on the user device or any other device on a network.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of U.S. patent application Ser. No. 18/356,934, filed Jul. 21, 2023, now U.S. Pat. No. 12,052,259, issued Jul. 30, 2024, which is a continuation of U.S. patent application Ser. No. 16/395,003, filed Apr. 25, 2019, now U.S. Pat. No. 11,729,175, issued Aug. 15, 2023, which are hereby incorporated by reference in their entirety. BACKGROUND Distributed ledgers may be implemented for use with various technologies. For example, distributed ledgers may have applications to Internet of Things (IoT) devices. IoT devices may be constrained by storage and/or processing capabilities. Developers for distributed ledgers may face issues, such as issues with size and/or growth of the distributed ledger, cost associated with storage of the distributed ledger, increased network transmission time, increased central processing unit (cpu) time for validation of the distributed ledger, as examples. SUMMARY Indications of permissions associated with a user device may be stored on distributed ledgers. The distributed ledgers may comprise a primary distributed ledger stored on the user device. The primary distributed ledger may comprise records indicating active permissions. The distributed ledgers may comprise a secondary distributed ledger stored external to the user device, such as on a network computing system. The secondary distributed ledger may comprise entries indicating inactive permissions, such as expired, invalid, and/or revoked permissions. Based on determining that a permission recorded on the primary distributed ledger is no longer active, an indication of the inactive permission may be recorded on the secondary distributed ledger. An updated primary distributed ledger may be generated that does not comprise the inactive permission. The updated primary distributed ledger may be stored to the user device. Storing and/or processing the updated primary distributed ledger, rather than a distributed ledger comprising entries indicating both active and inactive permissions, may result in reduced consumption of and/or requirement for storage and/or computing resources.

The blocks may indicate device associations. For example, the blocks may indicate devices associated with a common entity. The common entity may comprise a common user, a common group of users, a common account, and/or a common premises, as examples. The distributed ledger may be split, such as into an active branch (e.g., primary branch) branch and a secondary branch (e.g., folded branch). The active branch may comprise blocks comprising live (e.g., active, valuable, valid, etc.) transactions. The secondary branch may comprise blocks comprising inactive (e.g., not valuable, invalid, expired, no longer useful or needed, etc.) transactions. Blocks comprising inactive transactions may be removed from the active branch. The blocks comprising inactive transactions may be added to the secondary branch. Blocks in the secondary branch may comprise a new block number. The new block number may indicate a position in the secondary branch. The blocks in the secondary branch may comprise an original block number. The blocks in the secondary branch may comprise a reference to the original block number. Blocks in the active branch may comprise a new block number. The new block number may indicate a position in the active branch. The blocks in the active branch may comprise an original block number. The blocks in the active branch may comprise a reference to the original block number. The original distributed ledger may be reconstituted by merging the active branch and the secondary branch using original block numbers. The secondary branch may be stored in a network computing environment, such as a cloud computing environment. The active branch may be transmitted to one or more user devices. The one or more user devices may use the received active branch to determi
