Disclosed are methods and systems for recording data based on a plurality of blockchain networks. One method comprises: generating a first-type blockchain transaction comprising the data; transmitting the first-type blockchain transaction to the first-type blockchain network; recording one or more first-type blockchain transactions into a first-type block; recording the first-type block on a blockchain of the first-type blockchain network; obtaining the first-type block; generating a second-type blockchain transaction comprising the transaction hash; transmitting each second-type blockchain transaction to the second-type blockchain network; recording one or more second-type blockchain transactions into a second-type block; and recording the second-type block on a blockchain of the second-type blockchain network.

A service node receives a document creation request sent by a first user for creating a digital document of title of a target asset. The document creation request includes first configuration information of a digital document of title to be created. The first configuration information is generated by the first user by performing a configuration operation on each component in a corresponding first document template based on related information of the target asset. The first document template is a template that matches the related information of the target asset in a plurality of document templates corresponding to a first blockchain. A digital document of title is generated based on the first configuration information and a predetermined document generation rule, and stored in the first blockchain, so the target asset is circulated by using the first blockchain based on the digital document of title.

An improved blockchain is described herein in which a user burn transaction can be used to increase the probability that another node is selected as a leader. For example, a node can submit a user burn transaction that references a block commit submitted by another node, and may indicate an amount of cryptocurrency being burned in the user burn transaction. The amount of cryptocurrency being burned in the user burn transaction can be summed with the amount of cryptocurrency burned in the block commit referenced by the user burn transaction to determine the probability that the node that submitted the block commit is selected as a leader. While the node that submitted the user burn transaction cannot be selected as a leader, the node that submitted the user burn transaction can share in a portion of the block reward awarded to the node selected as the leader.

Methods and systems for managing and/or processing a blockchain to maintain data security for confidential and/or personal data are provided. According to certain aspects, the disclosed data security techniques may enable access sharing functionality utilizing the blockchain. For example, access sharing may be utilized to file documents, share policy information, and/or comply with an audit. The data security techniques disclosed herein also enable the use of smart contracts to transfer funds associated with payment obligations and/or other forms of blockchain based payments, comply with anti-money laundering requirements, report industry data, validate interest payments and/or maintain agent sales data. Data security may be achieved through the use of public key/private key encryption techniques.

There is provided a wireless communication device that includes a communication unit that performs wireless communication with a connection device, and a control unit that encrypts a wireless communication channel with the connection device on the basis of a digital certificate issued by a certificate authority server. The communication unit receives payment information and a valid type of payment from the connection device via the encrypted wireless communication channel. The control unit determines a payment server on the basis of the valid type of payment and causes the communication unit to transmit a payment request based on the payment information to the payment server.

Auditing shelf space of an outlet of a retailer using a device comprising: a computer, a camera, a global positioning system receiver and a repository. The device is authenticated using the time and date of the audit, and a location of the audit at the outlet of the retailer. Once the device is authenticated, images of displays within the outlet and audit information relating to the display and the outlet of the retailer are captured and audit information is embedded into the captured image. The captured image is encrypted and sent to a remote computer of a checker company for a compliance check.

A computerized system for verification and management of a digital asset, including an immutable digital asset, comprising: a computer system a sensor and a set of non-transitory computer readable instructions that can include instructions adapted for: receiving a digital asset from a creator of the digital asset; receiving significant information wherein the significant information is taken from a group consisting of date, time, event, individual, team, organization, notation, and any combination thereof; receiving identification information using the sensor of the creator; retrieving location information representing a physical location where the identification information is received, and the computer system is located; retrieving date and time information from the computer system; creating a digital asset record that includes a unique identifier associated with the digital asset, identification information, location information, and date and time information; and storing the digital asset record on the persistent storage.

Systems and methods are described to monitor consumption of a content item at a user device. Based on the monitored consumption, a token is generated, where the token represents an attribute of the content item and demographic data of a user associated with the user device. Access to the token is granted to a first content provider and denied to a second content provider based on received user input, and the token is converted into a first format. Converted token data associated with the first format is stored in a distributed ledger accessible to the first content provider and the second content provider, where the first content provider is capable of recovering the token from the converted token data, whereas the second content provider is not capable of such recovering. A content recommendation is received from the first content provider, based on the token recovered by the first content provider.

A system, method, and platform for analyzing company data. Source data regarding one or more companies is captured utilizing a data platform. The source data captured based on criteria including at least equality, diversity, and inclusion associated with the one or more companies is analyzed to generate company data for each of the one or more companies. The one or more companies are scored based on the criteria. The one or more companies are ranked based on the criteria. The company information including at least the scores and ranking from the data platform is communicated to one or more designated parties.

Techniques are described that include creating and retrieving equipment information via a digital distributed ledger-based system. The techniques include authenticating a user of a digital distributed ledger-based system. The techniques further include receiving an operations data from the user, wherein the operations data comprises equipment data logged during operations of an equipment. The techniques additionally include storing the operations data and identification information for the equipment in at least one or more blocks of a digital distributed ledger, and distributing the one or more blocks among nodes of the digital distributed ledger, wherein the digital distributed ledger is configured to immutably store the operations data.
