How does SCDO ensure security?
Answer: SCDO ensures the security and robustness of the blockchain network through multiple layers of measures: First, from the consensus mechanism, it adopts PoW (ZPoW), a consensus that has been proven to be secure, ensuring that no one can easily tamper with block records. Only miners who invest real computing power and work according to the rules can write blocks, and attackers would need to expend enormous resources to disrupt the network, fundamentally ensuring the immutability of the ledger.
Secondly, in terms of network architecture, SCDO introduces sharding and sub-chains, but each shard is maintained by a sufficient number of miners, and cross-shard consistency is ensured through cross-validation (light chains), preventing the situation where a shard is damaged in isolation without detection. The main chain monitors the sub-chains to prevent cheating from spreading to the main network. Third, SCDO employs mature cryptographic algorithms (such as ECDSA elliptic curve signatures) to ensure transaction signatures and account security, with the private key held only by the user, ensuring that account assets can only be managed by the owner. Fourth, the open-source audit mechanism enhances security: after the code is made public, it undergoes scrutiny by community developers, allowing for the timely discovery and fixing of potential vulnerabilities. The SCDO team also includes experienced security researchers who continuously conduct vulnerability testing.
Fifth, the network design prevents common attacks, such as DDoS resistance (reducing the impact of large-scale attacks through P2P network topology randomization), witch attack resistance (PoW itself requires cost, rendering witch nodes meaningless), and difficulty adjustment to cope with sudden increases or decreases in computing power, among others. Through these measures, SCDO has achieved comprehensive security assurance from consensus, cryptography, network protocols to implementation layers, providing maximum protection for on-chain data and user assets.
