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.

Abstract: Embodiments of the present disclosure provide methods and apparatuses for blockchain-based multi-party computation, a device and a medium, relate to blockchain technology in the field of computer technology. An embodiment of the method can include: encrypting business data, to obtain a ciphertext of the business data; hashing the ciphertext of the business data, to obtain a hash result of the business data; sending the hash result of the business data to a blockchain node, so that the blockchain node writes the hash result of the business data into a blockchain; and sending the ciphertext of the business data to a target trusted computing module in a target server, for instructing the target trusted computing module to perform multi-party computation based on the ciphertext of the business data and the hash result of the business data in the blockchain.
