WO_2022109851_A1

Resumen de: WO2022109851A1

Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for cross-chain communication in a blockchain-based trusted system. One of the methods includes receiving a message including ledger data by a first cross-chain communication component in a first blockchain network from a blockchain node in the first blockchain network. The first cross-chain communication component determines whether the ledger data is valid. If the ledger data is valid, the first cross-chain communication component generates formatted ledger data based on the ledger data, and send a cross-chain message including the formatted ledger data to a second cross-chain communication component in a second blockchain network.

BLOCKCHAIN-IMPLEMENTED METHOD AND SYSTEM

NºPublicación: EP4064167A1 28/09/2022

Solicitante:

NCHAIN LICENSING AG [CH]

JP_2022123070_PA

Resumen de: EP4064167A1

The computer-implemented invention provides a method and corresponding system for controlling access to and/or use of an internet-enabled resource. The invention uses a distributed electronic ledger such as, for example, the Bitcoin blockchain. The resource may be an IoT device or system. Access to the resource is permitted or enabled upon provision of a cryptographic key e.g. a private key which corresponds to a public key which has been stored in memory. In one embodiment, the public key is stored in a DHT. Access to the resource is prevented or disabled by removing the public key from memory, and using a redeem script of a blockchain Transaction to spend a tokenised output of a further blockchain Transaction. The process of communicating the requisite cryptographic keys and transferring funds is performed via the blockchain. The keys are communicated as tokens in the metadata of transactions scripts. In use, when access is requested by the user, an encrypted message is sent to the resource. The message has been encrypted using the user's private key. If the resource can use the previously communicated public key to decrypt the message, access can be granted. The invention is particularly suited for use in situations where temporary access or use of the resource is to be granted eg rental scenarios.

Exemplary embodiments provided herein include a method for safe creation, custody, recovery and management of a digital asset, agnostic to an underlying blockchain technology, the method including establishing a virtual layer where three private keys are generated, transacting the digital asset by using two of three of the private keys and multi-party computation techniques, abstracting interactions between the three private keys from the underlying blockchain technology, having a digital asset transaction considered as a single-signature by the underlying blockchain technology, and recovering the digital asset if any of the three private keys is no longer available. Additionally, the digital asset may be a cryptocurrency, and a party may be disconnected from any network during the normal user operation phases. Furthermore, the digital asset transaction may be considered as a single-signature, as seen by the underlying blockchain technology, and is associated to a public key PK_ABC.

US_2022277301_PA

Resumen de: US2022300956A1

Technologies are shown for secure management of a data file secured on a data file management blockchain that involve generating a genesis block for a data file management blockchain that contains a data file to be managed and signing the genesis block to commit the genesis block to the data file management blockchain. One or more transaction data blocks are generated for the data file management blockchain that each include a modification to the data file and the blocks are signed to commit them to the blockchain. In some examples, the modifications describe changes to the data file and the transaction data blocks are traced to the genesis block and a current data file generated by applying the modifications on the transaction data blocks to the data file in a sequence determined by an order of the one or more transaction data blocks in the data file management blockchain.
