Abstract: Users of a multisignature wallet can customize keys to initiate various transactions. As a user specifies roles to customize keys, a smart contract is updated to associate the roles with the keys, where the customized keys are then associated with the user's multisignature wallet. The user may perform transactions by signing using the key or an address of the key, where a transaction can be processed upon verifying the key and its role. Additionally, a privacy service can facilitate blockchain transactions initiated using a key of a multisignature wallet. The privacy service receives a transaction signed by a key of the multisignature wallet and identifies a proxy wallet using the key. The privacy service validates and signs the transaction, which is then sent to a proxy wallet. The proxy wallet can cause a blockchain transaction to be executed.

Abstract: A system and a method are disclosed for using a client that is unsynchronized with a blockchain network to validate blockchain transactions for IoT devices, web apps, mobile apps, and other applications. The client retrieves a register of nodes (acting as information provider or validator) that are synchronized with the blockchain network, selects a node from the register, and transmits an information request to the selected node. The client receives a response to the request, the response including the requested information and validation indicia (e.g., proofs), and determines whether the response is valid based on the validation indicia. The client transmits, in response to determining that the response is valid, a confirmation to the IoT device, web app, mobile app or other applications.

Abstract: Systems and methods for validating transactions distributed ledger transactions. In some embodiments, a request may be received to validate a proposed transaction for layer 2 processing for a distributed ledger. In response, a cryptographic configuration involved in the proposed transaction may be identified, and the proposed transaction may be checked against one or more transaction rules of the cryptographic configuration. In response to successfully checking the proposed transaction against the one or more transaction rules of the cryptographic configuration, the proposed transaction may be signed as part of a joint signature process with a validation key associated with the cryptographic configuration.

Abstract: A distributed ledger, e.g., blockchain, enabled operating environment includes a user device that accesses services of a service device by leveraging the decentralized blockchain. For example, a user device can lock/unlock a door (e.g., service device) by interfacing with a smart contract stored on the decentralized blockchain. The user device provides parameters, such as payment, that satisfies the variables of the smart contract such that the user device can access the service device. The service device regularly retrieves information stored in the smart contract on the decentralized blockchain. For example, the retrieved information can specify that the user device is authorized to access the service device or that the service device is to provide a service. Therefore, given the retrieved information, the service device provides the service to the user device.
