Methods, apparatus, and articles of manufacture for decentralized data storage and processing for IoT devices are disclosed. An example apparatus includes memory; and a processor to cause storage of a contract in an off-chain datastore; generate a hash value of the contract; cause storage of the hash value on a blockchain to be accessible to multiple nodes in an IoT network; and cause storage of a transaction on the blockchain, the transaction corresponding to an objective of the contract based on data sensed by an IoT device in the IoT network.

In some implementations, a system can be configured to allow remote control devices to quietly obtain status information related to various audio/video playback devices. For example, a streaming device (e.g., a user device, phone, etc.) can establish a streaming connection to a playback device. The playback device can be configured to only accept a single streaming connection (i.e., master connection). A remote control device (e.g., a user device, phone, etc.) can quietly connect (i.e., control connection) to the playback device without interrupting the master connection to obtain status information related to the playback device and or the media being streamed to the playback device. The remote control device can provide commands through the control connection to adjust the playback of the streamed media at the playback device.

The current disclosure is directed towards efficiently generating random sequences on a large-scale peer-to-peer network. In one example, the disclosure provides for selecting a first node based on a block generation order, where the first node is selected to generate a current block, adding a first signature share of the first node to the current block, adding at least a second signature share from a previously selected node to the current block, generating a random sequence based on the first signature share and the second signature share, adding the random sequence to the current block, and publishing the current block to a blockchain maintained by a node pool. In this way, a random sequence may be generated on-chain, with linear messaging complexity, without relying on a single trusted party/apparatus, which may thereby decrease a probability of any single party controlling the random sequence produced.

Adjusting communication channels used by camera to communicate with a base station are described. In one aspect, characteristics of communication channels can be determined and the operation of the camera can be adjusted to use a communication channel based on a comparison of the characteristics of multiple communication channels.

A peer-to-peer (P2P) distributed data management system (DDMS) may operate as an operating system on which P2P distributed applications are utilized to manage data on distributed ledgers, such as blockchains. The DDMS may enable fast development of secure and scalable enterprise P2P distributed applications that support permanent control of every piece of data on a distributed ledger, synchronization, normalization of the data, and encryption of the data. Security of the data in the distributed ledger means that even if someone hacks into the distributed ledger, access is only gained to one block of data (e.g., single email) and not all blocks of data (e.g., entire email account). The DDMS may be integrated into Internet-of-Things (IoT) devices. The DDMS further automatically supports sequential smart contracts on the distributed ledger.

The disclosure is related to adaptive encoding of video streams from a camera. A camera system includes a camera and a base station connected to each other in a first communication network, which can be a wireless network. When a user requests to view a video from the camera, the base station obtains an encoded video stream from the camera and transmits the encoded video stream to a user device. The base station monitors multiple environmental parameters, such as network parameters, camera parameters, and system parameters of the base station, and instructs the camera to adjust the encoding of the video stream, in an event one or more environmental parameters change.

One or more embodiments of this specification provide methods and apparatuses for transmitting messages. A method includes: registering, based on a registration request sent by each blockchain node in a blockchain relay communication network, a blockchain node to a blockchain node set indicated by the registration request; determining, in response to receiving a blockchain message to be sent to a target blockchain node set, a target blockchain node registered to the target blockchain node set and a target relay node in the blockchain relay communication network; and transmitting the blockchain message to the target blockchain node through the target relay node.
