The computer-implemented method includes: i) broadcasting a transaction, by a node in a blockchain network, to a congress pool to join a congress formed of a group of nodes; ii) after the congress has accepted a request from a requester to activate a script, preparing, by the node, a blockchain transaction cryptographically locked with a public key associated with the congress; iii) cooperatively generating, by the node in cooperating with other nodes of the group, a valid cryptographic signature for the transaction to spend the transaction; iv) after the blockchain transaction has been unlocked, receiving data from the plurality of information providing systems; v) determining a centre point for the data received from the plurality of information providing systems; and vi) activating, by the node in cooperation with other nodes of the congress, the script based on the centre point.

METHOD AND SYSTEM FOR GENERATING RULES FOR DATA ACCESS CONTROL

Resumen de: EP4530908A1

A method of generating an ODRL rule for controlling a device, a method of data access control, a system, a computer program and a computer-readable storage medium are disclosed. The first method includes: receiving a policy ontology; receiving a data asset information and at least one parameter; generating the ODRL rule for controlling the device based on the policy ontology, the data asset information and the at least one parameter from the device. The second method includes: generating a first ODRL rule, based on a first data asset information and at least one first parameter provided by a data producer device; sending the first ODRL rule to the data producer device; generating a second ODRL rule, based on a second data asset information and at least one second parameter provided by a data consumer device; sending the second ODRL rule to the data consumer device; receiving a aggregated specification based on the first ODRL rule and the second ODRL rule from the data producer device, and adding the aggregated specification to a distributed blockchain.

SYSTEM AND METHOD FOR AUTHENTICATING OFF-CHAIN DATA BASED ON PROOF VERIFICATION

Resumen de: EP4531329A2

Determining when and/or how to execute a program or script published to a blockchain network may rely on data that is external to the blockchain (i.e., external data) such as data about the real-world state and events. A prover (e.g., a node of the blockchain network) may perform one or more computations on behalf of a client, such as the execution of the program. To execute the program properly, the prover may rely on external data, which the prover may obtain from a data provider that has a trust relationship with the client (e.g., the client accepts as valid data provided by a trusted data provider). Systems and methods described herein may be utilized by a prover to provide cryptographically verifiable assurances of the authenticity of input data purportedly obtained from a data provider, the input data utilized in the execution of a program or script published to a blockchain network. An example of a blockchain network is a Bitcoin-based network.

Blockchain-Based Dedicated Device for Air Rights Trading and Verification

Resumen de: AU2023215108A1

The present invention relates to a system for specifying and trading air rights using non-fungible digital tokens, the system comprising: headquarters for controlling the system; an air rights trading marketplace in which air rights issued as non-fungible digital tokens through a network are specified and air rights trading is carried out according to air rights registration information, air rights height restriction information, and agreed-upon transaction conditions; an operation unit for mediating the input and output of information; buyers, sellers, intermediaries, and authorities who access the air rights trading marketplace through the operation unit and possess respective electronic wallets; and distributed storage in which the originals of all air rights information set for specification are distributed outside the headquarters via the network and stored in an air rights registration table, an air rights height restriction table, and a transaction conditions table.

Resumen de: EP4531333A2

The invention relates to distributed ledge technologies such as consensus-based blockchains. Computer-implemented methods for securely providing undetermined data from a determined or undetermined source are described. The invention is implemented using a blockchain network, which may be, for example, a Bitcoin blockchain. A first transaction to validate is received at a node in a blockchain network, with the first transaction including a first script that includes at least a first value, at least a portion of which includes data that is unconstrained by a second script, and a second value. A second transaction is obtained. The second transaction having been validated and including the second script that, as a result of being executed, causes the node to obtain the first value and the second value as a result of execution of the first script, and validate, based at least in part on first value and the second value, that the data is associated with a data source. The first transaction is validated by executing the first script and the second script.
