A method for delegating access to a blockchain. The method is carried out by an access delegation device and includes: receiving an execution request from a terminal, including at least one identifier of a user and at least one command to execute an action within the blockchain, the command being encrypted via at least one encryption key belonging to the user; obtaining, according to the at least one identifier of the received user, at least one decryption key of the user for decrypting the execution command; decrypting the execution command; and sending, to the blockchain, a request for executing the decrypted execution command via the at least one decryption key.

Method for delegating access to a blockchain

A method for controlling access to a function of an application implemented by a device for controlling access to a function of an application. The control device is registered to a blockchain. The method includes: of receiving, from a first terminal, a first request to access at least one first function of the application, the application being registered in the blockchain, the request including at least one first identifier of the at least one first function and at least one identifier of the first terminal; and transmitting a response to the access request including at least one parameter for accessing the at least one first function and at least one second identifier of at least one second function registered in the blockchain, the at least one second identifier being associated with the at least one parameter.

Method and device for controlling access to a function of an application registered in a blockchain

A method is described for negotiating a contract between two parties in a telecommunications network, as well as devices implementing the method. The method includes distributing, by a first party, a smart contract comprising: a subscription method allowing a second party to distribute a transaction for subscribing to the contract proposal, a method for generating a personalised contract between the parties and requesting their registration in the blockchain, the personalised contract being generated on the basis of parameters included in the transaction, executing the subscription method by a terminal of the second party, the execution triggering the distribution of a transaction comprising parameters representing the acceptance of the contract proposal by the second party, and executing, by a mining device, the method for generating a personalised contract with these parameters.
