Abstract: Methods, systems, and techniques for storing a binary large object involve receiving, at a first node comprising part of a first blockchain, the binary large object; hashing the binary large object; sending the binary large object from the first node to at least one other node that is part of the first blockchain without using the first blockchain; and after the binary large object has been disseminated to at least the number of nodes on the first blockchain required to achieve consensus, storing a hash of the binary large object on the first blockchain. Sending the binary large object involves disseminating the binary large object to at least a number of nodes on the first blockchain required to achieve consensus.

Abstract: Methods, systems, and techniques for facilitating data transfer between blockchains, Data is sent from a first blockchain to a second blockchain. The data includes lineage verification data that permits the second blockchain to verify a lineage of at least one block of the first blockchain; a proper subset of all non-header data stored using the at least one block; and validity verification data that permits the second blockchain to verify validity of the proper subset of all non-header data sent to the second blockchain from the first blockchain. The proper subset of non-header data may be a slice of state data of an application stored in the first blockchain. The second blockchain verifies the lineage and validity of the data it receives, and creates a new block having non-header data comprising the data it received.

Abstract: Methods, systems, and techniques for performing hyperconvergence using blockchains involve running a hypervisor on a computer node, in which the hypervisor runs a host blockchain; and running on the hypervisor an emulated blockchain that emulates the host blockchain. The host blockchain may communicate with other blockchains via the emulated blockchain, thereby receiving actions to perform from those other blockchains and permitting those other blockchains to control the hardware on which the hypervisor and host blockchain run.
