A system, method, apparatus, and computer program product for interactively broadcasting value via a sound, a Wi-Fi, a Bluetooth, an email, a messaging, an RFID, or an NFC to incentivize direct consumer engagement. The system produces verifiable data on customer preferences, habits, and purchasing while using secure digital cryptographic technology to convey an item of value. The system is configured to transact a digital token normally carried on a blockchain leger in an off-ledger condition. The digital token is embedded with a media content. A mobile computing device having a representation of a digital wallet is configured to detect the digital token, decode the digital token and transfer the digital token back to the blockchain ledger. When validated by the blockchain ledger, the digital token is transacted to a digital wallet on the blockchain ledger.

A system described herein may receive a request for a blockchain network to perform a particular set of operations, such as executing chaincode recorded to a blockchain associated with the blockchain network. The system may receive Key Performance Indicators (“KPIs”) of nodes of the blockchain network, and may receive a consensus policy associated with the blockchain network. The consensus policy may indicate a particular quantity of result sets used to verify execution of a given operation by the blockchain network. The system may assign different nodes of the blockchain network to perform different portions of the requested set of operations. The assignments may be determined based on the consensus policy and the KPIs of the nodes. The system may aggregate result sets from different nodes in order to generate aggregated result sets, where the quantity of aggregated result sets satisfies the consensus policy.

Introduced here is a computational architecture (also referred to as a “computational infrastructure”) that addresses the limitations of traditional data management solutions using a highly secure data management solution coupled with consent-based sharing. At a high level, the computational architecture applies blockchain methodologies to both transaction data and business data such that both types of data are stored “on chain” in the same computational architecture. This enables several significant advantages over traditional data management solutions with respect to data security, data ownership, data sharing, and intelligence.

An improved gossip-protocol-based method, a device, a piece of equipment and a medium for incentivizing block propagation. By improving the Gossip protocol and embedding block propagation rewards, the block forwarding process is accelerated. The designed signature chain structure records the block forwarding path and ensures that the path information is not tampered with. By combining the signature chain structure with the block generation process, the rewards are ensured to be truly and reliably distributed. A block propagation reward distribution strategy is designed to prevent forwarding nodes from adding pseudonyms in the propagation path. Therefore, the method can reduce the blockchain stale rate and enhance the scalability and consensus performance of the blockchain by accelerating block propagation in the presence of selfish nodes, and addresses the problem that selfish nodes refuse to forward blocks to save communication consumptions in the current blockchain network.

A blockchain network may be used to improve upon public-key infrastructure by providing for fast and secure registration, revocation and update of digital certificates. A public key may be recorded on the blockchain by a certificate authority in such a manner that any third party may quickly and easily verify that the public key is certified by the certificate authority and that the certification has not been revoked. The certificate authority may be able to revoke the certification nearly instantaneously, and/or may be able to simultaneously certify a new key for the same entity while revoking the old key. In some cases, the ability to revoke a certification may be given to the owner of the public key or, in some cases, to one or even a group of other entities.

Trustless deterministic state machines can be implemented using a blockchain infrastructure and state machines can run concurrently over more than one blockchain transaction. The transactions can be done in a Bitcoin blockchain ledger. An unlocking transaction constraint that constrains an unlocking transaction to include a transaction input that references a previous transaction output is determined. A redeemable transaction is created to include a transaction output that includes an amount and a transaction locking script that includes the unlocking transaction constraint, with unlocking the amount being contingent upon execution of at least one unlocking script of the unlocking transaction satisfying the unlocking transaction constraint. The redeemable transaction is caused to be validated at a node of a blockchain network.

This application provides methods and systems for verifying safe, consistent and secure storage of data especially, but not limited to, situations where storage of the data is delegated to a third party. A data controller, Alice, takes at least one sample of her data D, performs an operation on it to produce a variation. She then calculates the root value of the Merkle tree that represents the data comprising the varied data sample. She sends her data to a storage provider, Bob, while retaining her sample(s) and the resulting Merkle root value(s). Alice does not tell Bob which sample(s) she has chosen, or the operations she has used in the variations, or any inputs to the operations. Alice can delete her original copy of the data. At a later date, Alice can verify that Bob still has her complete data and in its original state by requiring him to perform the same operation on the same data sample, calculate the root value of the resulting Merkle tree and send it to her. If Bob's root value matches Alice's root value, then Bob must have an original and complete copy of Alice's data otherwise he would not be able to calculate the correct Merkle root value. Embodiments can be arranged to fully automate the process, including implementing on a blockchain.

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.

Methods and systems are presented for providing a token exchange framework that enables exchanges of reward tokens corresponding to different reward systems and/or different merchants. The token exchange framework includes a blockchain for storing transaction data associated with transactions of reward tokens. During the onboarding process, reward systems associated with different merchants may be connected to the blockchain of the token exchange framework via one or more bridges. Reward tokens may be issued to represent reward data corresponding to the different reward systems, and can be freely exchanged within the token exchange framework via the blockchain. When a transaction for redeeming a reward is received, reward tokens in the blockchain can be converted into reward data corresponding to the merchant's reward system and process the transaction with the merchant using the converted reward data.
