Top 5 DeFi Applications

101 Blockchains

Decentralized finance is a distributed financial system where there is no centralized governing body. Decentralized finance or DeFi applications utilize peer-to-peer finance networks. These networks are powered by decentralized and distributed platforms. The DeFi application ecosystem is vast and it includes various types of apps such as wallets, lending platforms, infrastructure development suits etc. As there are many DeFi applications on the market, finding the top applications can be a difficult process. Here, we will discuss the top 5 DeFi applications – AAVE, Compound, MakerDAO, Synthetix, and MetaMask. These are some of the widely utilized applications on the market. If you want to learn more about decentralized finance applications, then we have you covered. 101 blockchains feature a blockchain course that focuses on decentralized finance and will help you understand the working mechanism of this new financial structure. Learn more about the course from here -> Introduction to DeFi Course https://academy.101blockchains.com/courses/defi-course Learn about additional courses and masterclasses for the finance sector -> Blockchain in Finance Masterclass https://academy.101blockchains.com/courses/blockchain-in-finance Central Bank Digital Currency (CBDC) Masterclass https://academy.101blockchains.com/courses/central-bank-digital-currency Enterprise Blockchains and Trade Finance Course https://academy.101blockchains.com/courses/enterprise-blockchains-and-trade-finance We also offer lucrative certification courses for professionals.

Smart contracts are the next version of automated contracts where the user won't have to rely on trust. Smart contracts are automated algorithmic digital forms of contracts where parties can exchange assets without any intermediaries based on specified rules. Here, the program within the smart contract will self-execute based on the conditions previously defined by the parties. There are certain benefits to using smart contracts such as autonomous, secured, interruption-free, trustless, cost-effective, fast performance, and accurate and error-free. But here, we will analyze the examples of smart contracts, such as how it can be useful in digital identity, supply chain management, insurance, etc. To help you understand how smart contracts work or how you can utilize this new form of technology for your personal gain, or company 101 Blockchains offers an array of courses. You can use these courses to learn more about smart contracts and its role in various sectors.

An Overview of Stablecoin

101 Blockchains

Stablecoin is a different type of cryptocurrency. These coins always have a stable price. As the prices of cryptocurrencies are highly volatile, stablecoin is a solution to this problem. Typically, the volatile nature of cryptocurrencies makes it impossible for companies to utilize them as an alternative to paper-based money. Thus, stablecoins can help out in that regard. Typically, there are 4 types of stablecoin – Fiat-Backed Stablecoin, Commodity-Backed Stablecoin, Cryptocurrency-Backed Stablecoin, and Seigniorage-Style/Non-collateralized Stablecoin. All of these four types have different architecture and use cases behind them. Even though there are many top stablecoins on the market, many tend to deal with lots of hurdles. For example, centralized nature, trust issues, regulations, and unstable nature are a few of the limitations. If you are thinking about utilizing the power of stablecoins in your company or project, then we recommend starting with a solid blockchain course on the topic. 101 Blockchains is one of the leading educational networks where we offer the best of the best materials for your needs. We have an array of masterclasses and courses on the topic, that you should definitely check out.

Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to: Create a campaign using Mailchimp with merge tags/fields Send an interactive Slack channel message (using buttons) Have the message received by managers and peers along with a test email for review But there’s more: In a second workflow supporting the same use case, you’ll see: Your campaign sent to target colleagues for approval If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team But—if the “Reject” button is pushed, colleagues will be alerted via Slack message Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Neuro-symbolic is not enough, we need neuro-*semantic*

Frank van Harmelen

Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”. All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Essentials of Automations: Optimizing FME Workflows with Parameters

Safe Software

Are you looking to streamline your workflows and boost your projects’ efficiency? Do you find yourself searching for ways to add flexibility and control over your FME workflows? If so, you’re in the right place. Join us for an insightful dive into the world of FME parameters, a critical element in optimizing workflow efficiency. This webinar marks the beginning of our three-part “Essentials of Automation” series. This first webinar is designed to equip you with the knowledge and skills to utilize parameters effectively: enhancing the flexibility, maintainability, and user control of your FME projects. Here’s what you’ll gain: - Essentials of FME Parameters: Understand the pivotal role of parameters, including Reader/Writer, Transformer, User, and FME Flow categories. Discover how they are the key to unlocking automation and optimization within your workflows. - Practical Applications in FME Form: Delve into key user parameter types including choice, connections, and file URLs. Allow users to control how a workflow runs, making your workflows more reusable. Learn to import values and deliver the best user experience for your workflows while enhancing accuracy. - Optimization Strategies in FME Flow: Explore the creation and strategic deployment of parameters in FME Flow, including the use of deployment and geometry parameters, to maximize workflow efficiency. - Pro Tips for Success: Gain insights on parameterizing connections and leveraging new features like Conditional Visibility for clarity and simplicity. We’ll wrap up with a glimpse into future webinars, followed by a Q&A session to address your specific questions surrounding this topic. Don’t miss this opportunity to elevate your FME expertise and drive your projects to new heights of efficiency.

Securing your Kubernetes cluster_ a step-by-step guide to success !

KatiaHIMEUR1

Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster. However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks. In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
