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.
