Abstract: Systems and methods for providing an online exchange system. The methods comprise: performing, by a computing device of the online exchange system, a first transaction in which an ownership of a collectible is exchanged for an electronic financial instrument backed by at least one asset having a tangible value; generating, by the computing device, a non-fungible token on a first digital ledger for verifying ownership of the collectible; and communicating information from the computing device to a system which generated the electronic financial instrument such that a block is added to a second digital ledger that indicates a change of ownership of the electronic financial instrument occurred during the first transaction.

Abstract: A delivery system for coordination of the receiving and distribution of goods and services throughout a building from outside vendors that do not have direct access is described. An intra-building delivery system is established that places low-profile kiosks in the lobbies and message areas of commercial and residential buildings. These kiosks may be deemed the “transfer point.” The delivery system may also use a building-specific web portal for allowing residents, employees, and business leaders to place orders through outside vendors and coordinate delivery from the lobby of a building to their offices or apartments. Kiosk dispatchers and delivery runners may use mobile/tablet applications to receive goods and services at the transfer point and to validate delivery through signature-based delivery acceptance by residents and employees.
