A method for reserving access to a shared space through use of a blockchain and smart contracts includes: storing a blockchain including a plurality of blocks, each block including a block header and one or more blockchain data values, wherein one of the one or more blockchain data values included in one of the plurality of blocks includes a smart contract including at least an identifier and one or more terms; receiving a reservation request, wherein the reservation request includes at least the identifier, a reservation time, a public key of a cryptographic key pair, and a digital signature generated using the private key of the cryptographic key pair; validating the digital signature using the public key; executing the smart contract using the public key and the reservation time; and transmitting one or more data values to an internet-enabled device as part of the execution of the smart contract.

Method and system for access control of shared spaces through blockchain

A method of verifying the destination of a transaction between nodes in a network includes receiving transaction information corresponding to a transaction between the nodes, where the transaction information comprises a unique destination identifier and a destination name and where the unique destination identifier defines a destination account of the transaction; obtaining from a storage unit a set of names used in previous transactions to that destination account; determining at least one disparity value between the destination name and the set of names; and producing a destination verification value based on the at least one disparity value, wherein the destination verification value is used to verify whether the transaction between nodes should proceed.

Method, apparatus and computer program for transaction destination verification

A method for verified data storage via blockchain includes: storing a blockchain comprised of a plurality of blocks, each comprised of a block header and a plurality of transaction values, the block header including a timestamp; receiving a transaction notification including an entity identifier and data values; validating the data values based on a validation notification received from a verifying entity; generating a new block header comprised of a current timestamp, a block reference value, and a transaction reference value, the block reference value being generated via hashing of the block header included in a most recent block based on the timestamp, and the transaction reference value being generated via hashing of new transaction values including the data values; generating a new block comprised of the generated new block header and the new transaction values; and transmitting the new block to a node associated with the blockchain.
