Abstract: A cooling system for a dispensing station includes a modular manifold that incorporates into the dispensing station. The modular manifold includes a recirculation block, an interface block, one or more expander blocks, and one or more spacer blocks that interconnect to produce the modular manifold. The modular manifold includes a recirculation line that couples at an inlet with a cooling fluid system to receive a cooling fluid therein and at an outlet with the cooling fluid system to deliver the cooling fluid from the modular manifold to the cooling fluid system. The modular manifold couples with a drink source and with a drink outlet of the dispensing station such that a drink flowing through the modular manifold from the drink source transfers heat to the cooling fluid circulating through the recirculation line resulting in a chilling of the drink prior to a dispensing thereof from the drink outlet.

Abstract: In some implementations, a data unit may be hashed to generate a hash. A cryptographic structure, such as a Merkle tree or other cryptographic structure, maybe generated based on the hash and published on a block chain or distributed ledger. A proof associated with the data unit may be provided. The proof may allow for independent verification that the data unit is certified. Responsive to obtaining the data unit as at least one data unit to be verified, the data unit may be hashed. The associated proof may be obtained, where the obtained proof includes an index describing a position of the hash among one or more other hashes in the published cryptographic structure. The cryptographic structure may be reconstructed based on the index of the proof. Certification of the data unit may be verified by proving that the hash belongs to a root of the published cryptographic structure.
