A blockchain network system comprising blockchain network servers and blockchain history archives (fig. 5, 121), the system allows transactions to be executed in the future based on scheduling messages (fig.14, S1) from user applications 105 (e.g. cryptocurrency wallets or self-invoking smart contracts). The scheduling messages cause the generation of transaction messages based on time or logic conditions set by the user applications. The scheduling messages are recorded in the blockchain history archives. The scheduling messages can be amendable by the user applications, generated by decentralised schedule message systems. The network servers and history archives can be scalable and run distributively and redundantly with other network servers and networks for fault tolerance. The system can maintain compatibility with existing systems like Bitcoin, Ethereum, Solana, and Cardano. Digital tokens may be generated when deploying a smart contract with the schedule message. A non-transitory computer-implemented method for managing schedule messages and/or generating digital tokens with expiration time in a blockchain network.

A computer-implemented method of secure communication between nodes of a network comprising a master node, a set of intermediate nodes, and a set of end devices. The network comprises a network path of intermediate nodes between the master node and a target end device. The master node generates an encrypted command message by encrypting a command message with a respective encryption key shared between the master node and the target end device, generates a blockchain transaction comprising the encrypted command message, and generates a first encrypted transit message by combining the blockchain transaction with a respective public key of one or more intermediate nodes of the respective network path and a respective public key of the target end device, and encrypting the combination with a respective encryption key shared between the master node and the initial intermediate node. The first encrypted transit message is sent to the initial intermediate node.

Methods, devices, and a data structure for processing large volumes of transactions in blockchain nodes without using a mempool. Incoming transactions are validated and added to a candidate block. Transaction identifiers are added to an ordered set of transaction identifiers in an array until complete. The completed array and its Merkle root are propagated to other nodes. A placeholder transaction may be used in the first array in place of a coinbase transaction and its Merkle path may be determined to enable replacement of the placeholder transaction by the coinbase transaction during mining. Subsequent arrays are appended to the consolidated list of transaction identifiers are they are completed to continuously build a growing candidate block for mining.

The concepts and technologies disclosed herein are directed to time-aware blockchain staged regulatory control of Internet of Things (“IoT”) data. A federation platform can receive a registration request from an enterprise edge platform to register a blockchain identifier for publication of public data on a public blockchain. The federation platform can determine if the registration request contains any restricted data parameters. In response to determining that the registration request does not contain any restricted data parameters, the federation platform can query a security module to obtain an encryption key. The federation platform can receive the encryption key from the security module and store the encryption key in association with the blockchain identifier and an enterprise edge platform ID that uniquely identifies the enterprise edge platform. The federation platform can return the encryption key to the enterprise edge platform and allow publication of encrypted public data to the public blockchain.

Computer-implemented methods for locking a blockchain transaction based on undetermined data are described. The invention is implemented using a blockchain network. This may, for example, be the Bitcoin blockchain. A locking node may include a locking script in a blockchain transaction to lock a digital asset. The locking script includes a public key for a determined data source and instructions to cause a validating node executing the locking script to verify the source of data provided in an unlocking script by: a) generating a modified public key based on the public key for the determined data source and based on data defined in the unlocking script; and b) evaluating a cryptographic signature in the unlocking script based on the modified public key. The blockchain transaction containing the locking script is sent by the locking node to the blockchain network. The lock may be removed using a cryptographic signature generated from a private key modified based on the data.
