BEIJING, Sept. 9, 2024 /PRNewswire/ -- WiMi Hologram Cloud Inc. (NASDAQ:WIMI) ("WiMi" or the "Company"), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced that it developed a blockchain-based asynchronous federated learning (BAFL). The framework combines blockchain technology and asynchronous learning mechanisms to build a federated learning environment that is both efficient and secure. Blockchain, with its decentralization, immutability and transparency, has become an important means to guarantee the security of federated learning systems. In BAFL, blockchain records the history of each model update to ensure the integrity and traceability of model da
BEIJING, Aug. 23, 2024 /PRNewswire/ -- WiMi Hologram Cloud Inc. (NASDAQ:WIMI) ("WiMi" or the "Company"), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced that its R&D team delved into the application potential of blockchain in the field of identity management. The decentralized nature of blockchain as an open distributed ledger offers the possibility of constructing a secure, transparent, and tamper-proof trust management system. Using graph theory and blockchain frameworks, the team proposed an abstract identity verification model and successfully mitigated popular cyber-attacks by implanting trust-related information in an encrypted blockchain archite
BEIJING, Aug. 8, 2024 /PRNewswire/ -- WiMi Hologram Cloud Inc. (NASDAQ:WIMI) ("WiMi" or the "Company"), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced that it developed a layer-2 blockchain payment channel rebalancing model technology. By building an additional protocol layer on top of the main chain, the layer-2 network aims to increase transaction speed and reduce costs without sacrificing the security of the main chain. The payment channel technology, as an implementation of the layer-2 network, allows users to conduct transactions off-chain and interact with the main chain only at the beginning and end of a transaction, effectively reducing the nu
