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.

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 relate to a service flow system and a service data processing method and apparatus. The system can include a management server, a distributed storage cluster and a block chain alliance network connected by a network, the block chain alliance network including a consensus node and at least one participant node. Through unified management of a management server, off-chain data is stored in a distributed storage cluster, then participants of each phase are defined for different projects, and the participants of the same phase of the same project share the same on-chain and off-chain data. Therefore, credible access of the participants to block chain data is solved, dynamic customizable phase management of the projects in a service flow is supported, the on-chain data and participants of each phase are strictly divided and managed, and associated management of on-chain and off-chain service flow data is also supported.
