Scroll (SCR): A New Frontier for Ethereum Scaling

What is Scroll (SCR)? Scroll (SCR) is a zkRollup scaling solution for Ethereum, aiming to improve its performance and usability. It is based on a technology called zkRollup, which allows the network to handle more transactions without sacrificing security. Scroll aims to make using Ethereum faster and cheaper, ensuring that even more people can participate in the Ethereum ecosystem. The term "zkRollup" stands for "zero-knowledge rollup." This technology combines many transactions into a single proof, which is then submitted to the Ethereum network. By doing this, Scroll can significantly reduce the amount of data that needs to be processed on Ethereum itself, making transactions quicker and less expensive. Who Created Scroll (SCR)? The specific creators of Scroll are not publicly known. What VCs Back Scroll (SCR)? Scroll has attracted significant attention from the investment community. Major venture capital firms have backed Scroll, showing confidence in its potential. Some notable investors include: Polychain Capital, Sequoia China, Bain Capital Crypto, Moore Capital Management, Variant Fund, Newman Capital, IOSG Ventures, etc. How Scroll (SCR) Works Principles Guiding Scroll Scroll operates based on four key principles, which guide its design and functionality: User Security: At the heart of Scroll is the belief that user security is paramount. By relying on the robust security features of Ethereum, Scroll ensures that users' funds and data are safe, even when interacting with Layer 2. EVM Compatibility: Scroll maintains compatibility with the Ethereum Virtual Machine (EVM). This means that developers can migrate their existing applications to Scroll without needing extensive changes. Users can enjoy a seamless experience as they transition to this new environment. Efficiency: Scroll aims to provide low transaction fees and quick processing times. It strives to offer a great user experience without compromising security. This efficiency is crucial for encouraging more people to use Ethereum and Scroll. Decentralization: Scroll is committed to decentralization across all layers of its community. By ensuring that no single entity controls the network, Scroll promotes a resilient and vibrant ecosystem. The goal is to create a system that is resistant to censorship and external attacks. Architecture of Scroll Scroll Node The Scroll Node is the primary interface for users and applications. It has three key modules: ● Sequencer: This module processes Layer 2 transactions. It gathers transactions from a waiting area (known as the mempool) and organizes them into blocks. The Sequencer then submits these blocks to the Ethereum base layer for further validation. ● Coordinator: After the Sequencer creates a new block, the Coordinator takes the execution details and sends them to a randomly selected Roller from the Roller Network for proof generation. ● Relayer: This module keeps an eye on both Ethereum and Scroll contracts. It ensures that the transactions and messages between the two layers are properly communicated. Roller Network The Roller Network is made up of several provers known as Rollers. Their job is to create validity proofs for the transactions processed by Scroll. They achieve this by using advanced computing methods, such as GPUs and other hardware, to speed up the proof generation process. When a Roller receives an execution trace from the Coordinator, it converts this trace into a format that can be used to generate proofs. Once the proofs are created, they are sent back to the Coordinator. Rollup and Bridge Contracts These contracts serve as the connection between the Ethereum base layer and Scroll. They ensure that data from Layer 2 transactions is available and that users can transfer assets back and forth between Ethereum and Scroll. The Rollup contract receives state data from the Sequencer and stores it on Ethereum, ensuring that this data is accessible. Meanwhile, the Bridge contracts allow for message and asset transfers between the two layers, making the whole system more interconnected. How Transactions are Processed Now that we understand the architecture, let’s look at how transactions are processed within Scroll. 1. Transaction Submission: Users submit transactions to the Scroll Node, where the Sequencer gathers them. 2. Block Creation: The Sequencer organizes these transactions into blocks and sends them to the Rollup contract on Ethereum. 3. Proof Generation: The Coordinator assigns the task of generating a validity proof for each block to a Roller. This proof confirms that the transactions were executed correctly. 4. Finalization: Once the proof is generated, it is sent back to the Coordinator, which then submits it to the Rollup contract for final verification. When the proof is verified, the block is finalized and added to the Scroll ledger. This entire process allows Scroll to handle many transactions quickly and securely, leveraging the strengths of Ethereum.

Master Trading Psychology: Stick to Your Personal Ideal Prices to Maximize Profit and Minimize Loss

Seasoned investors and newcomers alike often grapple with one fundamental question: How do you make rational decisions in the crypto market? The answer lies in understanding and strictly adhering to your personal ideal prices for both profit-taking and loss-cutting. In this last lesson of Master Trading Psychology, we'll explore the significance of setting personal ideal prices and employing take-profit and stop-loss functions, all in the quest to maintain discipline and minimize negative impacts from event risks. Personal Ideal Prices: Your North Star in Crypto Trading Every trader starts their crypto journey with a set of expectations about coin prices. This is akin to having a personal ideal price in mind. For instance, a trader may believe that buying Bitcoin at $25,000 is an attractive entry point and decides to sell it at $35,000. These price levels serve as guiding stars in a trader's strategy. The personal ideal price is not a fixed, universally applicable number. It's an individualized benchmark that reflects your risk tolerance, investment goals, and market analysis. Understanding and adhering to these personal ideal prices can make a world of difference in your crypto trading journey. The Power of Take-Profit and Stop-Loss Functions To turn these personal ideal prices into actionable strategies, traders often employ two essential tools: take-profit and stop-loss functions. These functions automate the execution of a trade when a predefined price is reached, either to secure profits or to limit losses. Some of their advantages can be listed as follows: - Discipline in action: The crypto market is notorious for its emotional roller coaster. Prices can change within minutes, triggering panic or euphoria. By setting and sticking to your personal ideal prices using take-profit and stop-loss orders, you remove the emotional aspect from trading. This discipline ensures you won't succumb to the fear of missing out (FOMO) or irrational excitement. - Risk mitigation: Crypto assets have relatively big price swings. Without stop-loss orders in place, your investments could suffer great losses if a bear market suddenly emerges. By having a predetermined exit strategy, you protect your capital and mitigate potential damage. - Profit realization: The take-profit function acts as a safeguard against greed. When the market reaches your target price, it triggers the sale, ensuring you lock in your profits. Many traders have seen their gains evaporate because they held onto an asset for too long, hoping for even more significant gains. - Risk preparedness: Risks in the crypto world are not uncommon. From regulatory crackdowns to sudden market crashes, unforeseen events can wreak havoc on your investments. By having stop-loss orders in place, you're better prepared to limit your losses in case of a hazard. Executing a Rational Strategy Implementing your personal ideal prices and take-profit/stop-loss orders should be a well-thought-out process. Here are a few tips to make your strategy more effective: - Regularly update your strategy: The crypto market is dynamic, and your personal ideal prices should evolve with it. Regularly reassess your investment goals and adapt your strategy accordingly. - Diversify your portfolio: Don't put all your eggs in one basket. Diversifying your holdings across different cryptocurrencies can help spread risk and reduce dependency on a single asset's performance. - Continuous learning: Stay informed about the latest developments in the crypto space. Understanding the market and the assets you're trading will help you make more informed decisions. Disclaimer: The opinions expressed in this article are for informational purposes only.
