Abstract: Embodiments of the present disclosure disclose a method and apparatus for verifying digital identity, a device and a storage medium, and relate to the technical field of blockchain. An implementation of the method can include: acquiring target login information of a target verifier, in response to a login operation of a target user on the target verifier; sending, based on the target login information, a login request including a target user decentralized identity (DID) of a target user to the target verifier, to authorize the target verifier to acquire a target claim of the target user from an identity hub of the target user and verify the target user DID and the target claim; and logging in to the target verifier using the target user DID, in response to the target user DID and the target claim passing the verification.

Abstract: Embodiments of the present disclosure relate to the field of blockchain technology, disclose a method, apparatus, and storage medium for processing an ethereum-based falsified transaction, and solve the problem of the existing technologies failing to achieve validating falsification resistance of an ethereum consensus algorithm in engineering. The method includes: sending a falsified transaction to a preset node of in ethereum network, such that the preset node broadcasts a block including the falsified transaction to all nodes in the ethereum network; and determining whether the falsified transaction successfully attacks the ethereum network based on information on a chain maintained by a node in the ethereum network. The embodiments of the present disclosure apply to the process of validating the falsification attack resistance of the ethereum network consensus algorithm.
