A new CertiK series giving users bite-size tips and info to stay informed and safe in the #crypto space. Episode 11: What is Centralization vs Decentralization vs Distributed Networks? Learn more in under 2 mins! https://www.certik.com/products/pentest Transcript: Centralization, decentralization, and distributed networks are three different systems used for storing data. Centralization has been the status quo for web technology, making websites easy to use. A centralized network processes and stores data on a specific server. They allow engineers to roll out updates and fixes to the host server. Centralized networks often hire security firms to do penetration testing, which simulates a network attack. With centralization, if a server suffers downtime the entire network grinds to a halt. Decentralization offers more security and helps mitigate attacks. A decentralized network operates across many different nodes. Each node holds the entire database and verifies its version against each other to achieve consensus. A decentralized network requires more effort to update, has a greater environmental impact through its energy consumption. A distributed network operates like a decentralized system but may not require each node to host all of its data independently. Increased transparency is a key feature with each node having equal access to the data. This also makes it difficult to change information in the network. Smart contract auditing has risen from new types of attacks on decentralized and distributed networks. Whether it be Penetration Testing or Smart Contract Auditing choosing the right technology will ensure greater success.

See where to go, what to look for, and more on your #crypto journey at: https://certik.com https://www.youtube.com/c/GirlGoneCrypto Transcript: Okay so let’s say you’re checking out a project and are doing your research and you see that it’s been audited. Great, phew, sigh of relief… but hold up… just because a smart contract was audited doesn’t necessarily mean the audit was good. When doing your own research, it’s important to go one step further and actually check out the audit report. Now reading audit reports might sound a little complicated and technical, but it’s actually a lot easier than you think. So in this video, we are going to dive into how to read and evaluate a CertiK audit report. So first of all - what kind of information do these reports actually look at? A security audit is a line-by-line inspection of a smart contract's code. Smart contracts are self-executing agreements between a buyer and seller that are stored on a blockchain. Security audits can reveal vulnerabilities in a smart contract by identifying coding errors and potential risks. CertiK essentially examines these smart contracts and blockchain ecosystems. CertiK’s security experts manually review these contracts, using AI solutions and mathematical approaches to analyze their quality. So now let’s dive into the HOW. Where do you go to find this information and what should you be looking for? When you visit CertiK.com, you’ll notice a search bar on their Security Leaderboard. Type in the name of the particular project you’re interested in. This will take you to the project’s full audit report. Under the Findings section, check to see that the vulnerability issues have been identified and fixed. If a project has unresolved issues, it’s important to research why. CertiK only audits contracts sent to them, so make sure to check which contracts were audited and always review the report in detail.

Episode 10: What is an Online Attack? Learn about #onlineattacks and more in under 2 mins! https://certik.com/products/skynet Transcript: Through decentralization, blockchain technology can improve the safety of online activities. Many online attacks use Attack Vectors to exploit system weaknesses. DDoS, Eclipse, and a 51 Percent Attack are three common types. A DDoS, Distributed Denial of Service, attack, occurs when hostile hackers overload a network with requests. In blockchain, DDoS target crypto exchanges or mining pools. They disable a network's ability to serve users. Eclipse attacks control a single node inside an artificial environment. An attacker can manipulate communications with surrounding nodes to perform illegal transactions by isolating a node. When an assailant obtains control of 50% or more of a network's mining hashrate, it's called a 51 percent attack. The individual can submit fraudulent transactions, making the blockchain centralized. 51 percent attacks become difficult as a blockchain network increases in the number of honest nodes. Blockchain analytic tools such as CertiK’s Skynet help with online attacks by monitoring on-chain activity. To learn more about online attacks visit CertiK.com/resources.
