Question 51: How does the SCDO network 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 computational power and work according to the rules can write to the blocks. Attackers need to expend enormous resources to disrupt the network, fundamentally ensuring the irreproducibility of the ledger.
Second, in terms of network architecture, SCDO introduces sharding and sub-chains, with each shard maintained by a sufficient number of miners, and cross-validation (light chains) ensures cross-shard consistency, preventing situations where a shard can be compromised 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 the security of transaction signatures and accounts. Only users hold the private keys, ensuring that account assets can only be controlled by their owners.
Fourth, the open-source auditing mechanism enhances security: the code, once made public, is subject to scrutiny by community developers, which can timely identify and fix potential vulnerabilities. The SCDO team also has experienced security researchers who continuously conduct vulnerability testing.
Fifth, the network design guards against common attacks, such as DDoS resistance (reducing the impact of large-scale attacks through P2P network topology randomization), witch attack resistance (the cost requirement of PoW makes witch nodes meaningless), and difficulty adjustment to respond to sudden increases or decreases in computational power. Through these measures, SCDO achieves comprehensive security protection from consensus, cryptography, network protocols to implementation layers, maximizing the protection of on-chain data and user assets.
