SHENZHEN, China, April 22, 2025 /PRNewswire/ -- MicroCloud Hologram Inc. (NASDAQ: HOLO) ("HOLO" or the "Company"), a provider of Hologram Digital Twins Technology, today announced the development of an innovative solution designed to effectively reconstruct blockchain systems when under attack. This solution leverages verifiable secret sharing (VSS) technology to ensure the blockchain can swiftly restore functionality while maintaining data integrity and consistency, even under extreme conditions. HOLO's blockchain reconstruction solution is comprised of the following key components: Verifiable Secret Sharing (VSS) VSS is a cryptographic method that divides a private key into multiple shares distributed among different participants. Individually, these shares hold no value; the original secret can only be recovered when a specified number of shares are combined. VSS protects private keys and ensures users can recover blockchain data even if certain nodes are compromised. Redundant Storage Across Distributed Nodes To enhance system fault tolerance, HOLO implements redundant storage on distributed nodes, meaning each node retains not only its ledger copy but also portions of other nodes’ ledger data. Consequently, if some nodes sustain damage, remaining nodes can utilize this redundant information to reconstruct lost data. Dynamic Participant Selection and Verification Selecting and verifying participants dynamically is vital in blockchain systems.

This approach ensures that only trustworthy nodes engage in blockchain maintenance and data reconstruction, significantly minimizing the risk posed by malicious nodes. Reward and Punishment Mechanisms To discourage dishonest reconstruction, HOLO established an incentive system that rewards users who participate honestly and penalizes those attempting to disrupt or tamper with data. This mechanism significantly bolsters the system’s security and reliability. Unlike traditional reconstruction methods, HOLO’s scheme activates immediately without requiring negotiation or trust establishment among different blockchain parties. Users can independently reconstruct their data without depending on other potentially untrustworthy participants. By combining VSS with incentive mechanisms, this solution substantially enhances blockchain security against malicious attacks. Moreover, all reconstruction processes are transparent and traceable, ensuring consistent data integrity.
