Question 63: How can developers develop DApps on SCDO?

Answer: The experience of developers developing DApps on SCDO is very similar to that on Ethereum. First, it is necessary to familiarize oneself with smart contract languages such as Solidity, and then use the SDK and documentation provided by SCDO to set up the development environment.

Common Ethereum development tools like Truffle and Hardhat can be used; just point the RPC endpoint to SCDO nodes to deploy and debug contracts.

The SCDO team provides a complete API interface and sample code, and developers can also refer to the SCDO Gitbook or Wiki. Deploying contracts and calling through the Web3 library is consistent with Ethereum.

After testing is complete, configure the DApp frontend to connect to the SCDO network (for example, by customizing the RPC through Metamask or using the official wallet).

Due to EVM compatibility, many Ethereum DApps can be migrated to SCDO with one click, requiring only minor adjustments to parameters. Therefore, as long as developers have Ethereum development experience, they can quickly get started with DApp development on SCDO and implement smart contract applications successfully.

Question 62: What types of decentralized applications (DeFi, NFT, etc.) does SCDO support?

Answer: Since SCDO is fully compatible with EVM smart contracts, various popular DApp types on Ethereum can theoretically be implemented on SCDO. In terms of DeFi, decentralized exchanges, lending protocols, yield farms, and other financial applications can be built. Regarding NFTs, SCDO supports NFT minting and trading, allowing unique tokens to be issued for art, game items, and more. Game and metaverse applications can also deploy sidechains to meet high-frequency interactions. Even cross-chain asset management and on-chain governance DApps can be migrated to SCDO. In summary, from financial services to digital collectibles and social networks, the SCDO ecosystem almost covers all imaginable blockchain application scenarios【32†L49-L54】. High performance and low fees make these applications run more smoothly on SCDO.

Question 61: What practical applications of SCDO are currently running in the ecosystem?

Answer: The SCDO ecosystem is still in the early expansion stage, and some infrastructure-type applications and demonstration projects have already gone live. For example, the official block explorer (like SCDOscan) is provided for users to query transaction and block information, and the official wallet is used for secure storage and transfer of SCDO. In the community aspect, some decentralized finance (DeFi) experimental projects, NFT minting, and trading platforms are under development. There is also the stablecoin scUSDO issued on the SCDO chain, providing users with assets pegged to fiat currencies. As developers get involved, DApps from different industries (such as gaming, social, and supply chain) are expected to gradually emerge, enriching the practical application scenarios of SCDO.

Question 60: What should be done if SCDO encounters an unexpected vulnerability or network fork?

Answer: If a serious vulnerability is discovered, the SCDO development team will quickly release a patch and notify node operators to upgrade their software to close the security loophole. For unexpected network forks (for example, chain splits caused by version inconsistencies), the community will select the legitimate chain through communication and negotiation: usually following the longest chain principle or the chain supported by the majority of miners as the main chain. The development team may convene miners and exchanges to take unified action to merge or abandon the split chain. In addition, the SCDO open-source community will also participate in decision-making to ensure that the handling process is transparent and fair. In short, in emergencies, quick response + community consensus is the strategy SCDO uses to solve problems, minimizing the impact.

Question 59: Is the SCDO network vulnerable to quantum computing threats?

Answer: Currently, SCDO uses an elliptic curve encryption algorithm similar to that of Bitcoin, and its resistance to general quantum computing is comparable to other mainstream chains in the short term. Truly powerful quantum computers may be able to break existing signature algorithms, but such capabilities have not yet emerged globally. Once a quantum threat approaches, SCDO can respond by upgrading the cryptographic algorithms through a hard fork (for example, by introducing quantum-resistant signatures). Therefore, in terms of the current technological state, SCDO's security risk against quantum computing is relatively low, but the team and community will continue to monitor advancements in quantum technology and prepare upgrade plans in advance.

Question 58: How does SCDO prevent malicious behavior of nodes?

Answer: In the SCDO network, most nodes are miner nodes or full nodes, which verify each other by running the protocol to prevent a minority of nodes from misbehaving:

1) Consensus Constraints: If malicious nodes attempt to publish blocks that do not comply with the rules (such as tampering with transactions or double spending), honest nodes will reject the block due to verification failure, preventing malicious actors from spreading false messages across the network.

2) Light Chain Verification: In a sharded architecture, if a shard maliciously fails to execute cross-shard transactions or forges states, other shards can identify anomalies and refuse to recognize them through light chain and cross-shard verification requests, preventing a single error from affecting the entire network.

3) Economic Incentives: Miner nodes need to consume electricity for mining and are incentivized for accurate bookkeeping. If malicious behavior results in the blocks they mine being invalid, the computational power previously expended is wasted, and rational nodes will not engage in prolonged malicious activities that harm their profits.

4) Punishment Mechanism: For sub-chain nodes, the main chain's challenge mechanism can be seen as a form of punishment — if a sub-chain validator is caught misbehaving, the SCDO tokens staked on the main chain can be confiscated

Question 57: How is the security of SCDO's wallet and private keys ensured?

Answer: In blockchain, the security of wallets and private keys is primarily determined by the user's own behavior and the design of the wallet software.

The official SCDO wallet follows industry security standards during development: private keys are stored locally in encrypted form and are not stored in plain text or uploaded to servers; the wallet provides a mnemonic backup mechanism, making it easy for users to recover their assets in case of device loss. When users first create a wallet, they need to write down and securely keep the mnemonic (or keystore + password), which is the only proof for asset recovery. The SCDO wallet strongly reminds users not to disclose the mnemonic or private key to anyone, and team members will not ask for it.

To further ensure security, users can store large amounts of assets in cold wallets or hardware wallets—currently, SCDO may be compatible with some general hardware wallets or achieve cold storage through offline signing. When transacting, the wallet uses cryptographic signatures, and the private key is not directly exposed to the network.

For common phishing attacks, official channels will list methods for identifying authenticity to prevent users from downloading fake wallet applications. In summary, not disclosing the private key is fundamental; once users properly store it locally, SCDO's wallet mechanism can ensure asset security.

It is important to emphasize that once encrypted assets are stolen due to private key leakage, they cannot be recovered, so users must play the role of "their own bank." Making multiple backups, storing them properly, and being vigilant against phishing websites and malware are the key ways to ensure the security of SCDO assets.

Question 56: What measures does SCDO have in place to prevent chain scams or illegal activities?

Answer: Like most public chains, SCDO itself is a neutral technology platform and does not have built-in functions to review transaction content. Therefore, it cannot actively filter scams or illegal transactions, as this would contradict the principle of decentralization. However, to protect user interests and ecological health, the SCDO community and development team have taken some measures on a soft level:

1) Compliance reminders: Through the official website, white papers, and community channels, users are reminded to be aware of investment and usage risks, not to trust promotions such as "guaranteed returns," and to emphasize that on-chain assets are at their own risk.

2) Blacklist publication: The community can voluntarily compile known scam addresses or contracts and publish them for user reference to avoid interactions with these addresses (but on-chain interactions will not be prevented; this is just a warning).

3) Cooperative supervision: If certain serious illegal activities occur (such as money laundering), the SCDO team will cooperate with judicial investigations, for example, by providing support for on-chain public data analysis.

4) Tool support: Encourage the development of third-party tools to provide risk assessment reminders for users' transactions. For example, wallet software can mark known scam contracts and remind users to be cautious before signing. It is important to understand that the SCDO network itself will not block any transactions; both good and bad transactions are recorded on-chain. Therefore, users must be more vigilant and recognize various scam tactics. The official stance is: education is more important than interception. By enhancing user awareness of security and providing information transparency, the likelihood of illegal activities succeeding can be reduced. In summary, SCDO provides an open platform. Although it cannot directly prevent crimes like centralized institutions, through community autonomy and external regulatory cooperation, it can curb the spread of illegal activities to a certain extent.

Question 55: Has SCDO undergone a third-party security audit?

Answer: As of now, the SCDO core protocol code has not been published with a comprehensive audit report from a well-known security company. However, as an open-source project, SCDO has undergone extensive review by community developers and has been tested through long-term mainnet operation.

Since the mainnet went live in 2021, there have been no major security incidents, which indirectly proves the reliability of the code.

In addition, the team members include experienced blockchain researchers and algorithm experts who have conducted rigorous testing and formal verification during the development process.

Some blockchain security communities have also researched and discussed SCDO's consensus algorithm, and no obvious vulnerabilities have been found. Of course, a formal third-party audit can further increase trust. SCDO or its community may invite independent auditing agencies in the future to review key modules (such as consensus, security protocols, contract VM) and publish the results.

If users are concerned about security audit conditions, they can follow the project’s official website announcements.

Currently, users can assess the project's security by reviewing SCDO's GitHub commit history and issues, as well as mainnet operation data.

The absence of an audit does not mean it is unsafe, but a formal audit is a kind of professional endorsement. In short, the SCDO core code has been running in a public environment for many years, and its security has undergone some verification. If authoritative audit reports can be introduced in the future, it will further enhance the community's confidence in the project's security.

Question 54: How is the security of smart contracts ensured in SCDO?

Answer: The security of smart contracts in SCDO is mainly ensured through platform mechanisms and developer practices. In terms of platform mechanisms, SCDO inherits the Ethereum verification execution model: contract code execution takes place within the EVM virtual machine, isolated from the underlying state, which prevents contracts from directly accessing off-chain systems and causing damage.

At the same time, each contract call has a Gas limit, and infinite loops or excessive computations will be safely terminated due to Gas exhaustion, preventing malicious contracts from blocking the network. Transaction and contract data is confirmed through consensus, irreversibly recorded on the chain, and contract results are transparent and publicly available, preventing unilateral tampering. Additionally, SCDO introduces some optimizations to enhance contract security: for example, regarding known vulnerabilities like the Ethereum DAO issue, developers can use currently mature versions of Solidity and security libraries to avoid reproducing past vulnerabilities.

SCDO may also provide contract templates and audit services for project parties to reference. On the other hand, security also depends on the developers themselves.

SCDO supports and encourages the use of audited open-source contract frameworks (such as the OpenZeppelin library) for development, and developers can utilize existing Ethereum security tools (such as MythX, Slither, and other static analysis tools) to review SCDO contracts, as both environments are similar. The community also advocates for third-party audits of important contracts. Although SCDO itself cannot prevent developers from writing vulnerable contracts, most common vulnerabilities can be avoided through a comprehensive development environment and accumulated experience.

In summary, the SCDO smart contract platform is secure and transparent in its underlying execution, while the specific contract security requires developers to follow best practices in conjunction with community oversight.

Question 53: What known blockchain attacks can SCDO resist?

Answer: SCDO has considered various known attack vectors in its design and has taken protective measures:

First, for the 51% attack, the ZPoW multi-target algorithm increases the difficulty of the attack and prevents attackers from monopolizing block creation for long periods with a single algorithm.

Second, in response to selfish mining attacks (where miners intentionally delay the release of blocks for profit), SCDO's fast block time and multi-sharding reduce the benefits of selfish mining, while community monitoring can promptly detect abnormal hash power behavior.

Third, witching attacks are inherently limited in PoW networks because creating massive false identities does not increase hash power but instead dilutes its efficiency. SCDO can resist this type of attack without additional measures.

Fourth, double-spending attacks occur when an asset attempts to be used in two transactions. Similar to Bitcoin, SCDO prevents double-spending through the longest chain consensus principle: once a transaction is confirmed on the chain, double-spending requires overturning existing blocks, which is not feasible with insufficient hash power. Additionally, the sharding design ensures that cross-shard transactions are ultimately consistent, preventing successful double-spending across different shards.

Fifth, denial-of-service attacks (DDoS): SCDO's P2P network utilizes random broadcasting and verification mechanisms, quickly discarding large amounts of invalid data without propagating it across the network. Miners also prioritize processing genuine transactions with higher fees, making it difficult for DDoS attacks to incapacitate the network.

Sixth, smart contract vulnerabilities: Although contracts are written by developers, SCDO provides a mature EVM environment compatible with various auditing tools and secure development models, allowing developers to leverage known best practices to avoid repeating Solidity vulnerabilities. Additionally, SCDO has no special backdoors, and once a contract is published, it cannot be arbitrarily modified, ensuring consistency in contract execution from a mechanistic perspective. Overall, SCDO can effectively resist consensus layer attacks such as 51% attacks, double-spending, DDoS, etc., and provides a mature platform for the security of smart contract application layers. No system is absolutely secure, but SCDO has made adequate preparations against known threats.

Question 52: Has SCDO addressed the security risks posed by computing power monopolies?

Answer: Yes, this is one of the key points of SCDO's security design. Computing power monopoly refers to a very small number of miners controlling most of the computing power, which could lead to network attacks or manipulation. SCDO has significantly reduced the likelihood of computing power monopolies through the ZPoW algorithm, which weakens the advantages of mining machines and balances multiple algorithms.

This is specifically reflected in:

1) Hardware Equality: Because of the special algorithm, ordinary graphics cards and even CPUs can participate in mining, and professional mining farms no longer have an overwhelming advantage as they do in Bitcoin. This naturally leads to a more distributed computing power among many small and medium-sized miners.

2) Multi-Algorithm Offset: Even if a certain miner has extremely strong computing power in a certain algorithm, the network will increase the difficulty of that algorithm, forcing it to compete evenly with other miners. Large miners cannot maintain an advantage in all algorithms simultaneously.

3) Sharding Parallelism: Miners need to choose sharding mining, and the multiple chains in parallel make it more difficult for any single miner to monopolize all shards of the entire network, requiring at least multiple times the resources to do so.

4) No Pre-Mining and Fair Distribution: No team or early investors hold large amounts of tokens, eliminating the economic privilege of a miner's status. Due to these measures, SCDO has essentially avoided the situation where the top mining pools control more than half of the computing power, as seen in Bitcoin. The more decentralized the network's computing power, the higher the security. Therefore, it can be said that SCDO has effectively mitigated the risks of computing power monopolies through technical means and distribution mechanisms, adding a layer of defense to network security. Of course, continuous community attention to the miner structure is also necessary to prevent new centralization trends, and if discovered, adjustments in parameters or algorithm upgrades can be made to respond.

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.

Question 50: How can users acquire and store SCDO tokens?

Answer: There are mainly two ways to obtain SCDO tokens:

Firstly, through mining, which is the most original method. Anyone who contributes computing power to mine blocks will receive SCDO rewards (see the mining section for details).

Secondly, through trading, that is, exchanging SCDO for fiat currency or other cryptocurrencies on digital currency trading platforms that support SCDO. Some exchanges have already listed SCDO trading pairs (such as SCDO/USDT, etc.), but investors should ensure that the platform has a legal license and complies with local regulations when using it. Additionally, individuals can also trade SCDO privately in over-the-counter transactions, but safety and credibility should be taken into account. Regarding storage, users typically keep SCDO in digital wallets. The official SCDO provides decentralized wallets (including the web-based SCDO Wallet and mobile wallet applications), making it convenient for users to manage assets and make transfers. These wallets will provide users with private keys/mnemonic phrases, which must be kept secure. Some third-party wallets (such as HyperPay and other multi-chain wallets) have also announced support for SCDO, and users can choose their preferred wallet tools. Furthermore, since SCDO is EVM-compatible, some Ethereum wallet tools may also be compatible with SCDO assets after adjusting network parameters. Regardless of which wallet is used, it is essential to ensure that the official or trusted version is downloaded and that keys are backed up to avoid asset loss.
