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.

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 and systems are presented for providing rewards and enhanced user experience via blockchain technologies. A reward system uses blockchain technologies to evaluate one or more attributes of a wireless connection between two user devices. A first user can scan a code associated with an instance of a product, where the instance of the product is associated with a second user. A wireless connection can then be established between the two devices, and content stored on the device of the second user and associated with the instance of the product can be transmitted to the device of the first user. Certain attributes of the wireless connection and the content shared can determine what type of reward the second user is given.
