Abstract: In some embodiments, a network node for securing physical assets may be provided. The network node may include a processor and a memory storing instructions. The network may be configured to: receive, from a first entity, a cryptographic data structure configured to identify a physical item stored in a secured location; in response to receiving the cryptographic data structure, generate and transmit to the first entity a plurality of fungible cryptographic items; secure the cryptographic data structure on a public data structure, such that the cryptographic data structure cannot be released unless the plurality of fungible cryptographic items are received; receive, from a second entity, the plurality of fungible cryptographic items; and in response to receiving the plurality of fungible cryptographic items, transmit to the second entity the cryptographic data structure.
