If you want to:

  • Quickly gain fundamental blockchain knowledge

  • Use a metric-base assessment framework to make informed decisions

  • Have example assessments of major Layer1s already bring you way ahead of 95% of the people in the space

Then this eBook is for you👇

A 3-Step Metrics-Based Assessment Framework for Layer1 Blockchains (eBook) (ENG)

🏆 The First Book in Crypto that provides a metric-based Assessment Framework to evaluate Layer1 Blockchains based on the dimensions of the Blockchain Trilemma. It's an easy-to-understand and accessible Assessment Framework for blockchain evaluation based on the 3 dimensions of the Blockchain Trilemma indicating the degree of decentralization, scalability, and security.❓Maybe you know some or all of this: ❌ You are new to the crypto space and you feel lost in all the diverse and opposing information❌ You don't know where to look for trustworthy information❌ You have no time to do endless hours of research❌ You have been in the crypto space for a while and you are tired of all the hype and coin pumps.❌ You want to build your profound understanding of different blockchain projects❌ You want to understand the differences between projects from a fundamental, metrics-based perspectiveBut don't worry. We have been there, too. This is why we wrote this book!When it comes to classical stock evaluation, standardized frameworks, metrics, and procedures exist.What is already common sense in this asset class is a green field in the crypto market. Here, many bases their investment decisions due to complexity and information asymmetries on following the hype on Twitter or the narrative of influencers who might just want to dump a coin.This eBook sheds some light on the currently unstructured, distributed, and inconsistently crypto asset market.🤔 How is this possible, you might ask?The ebook provides you with a go-to framework for a Layer1 Proof of Stake Blockchain Assessment.......so that you will be able to understand:✅ What is the difference between stock evaluation and crypto assessments?✅ Why is a metric-based Assessment Framework essential to evaluate Layer1 blockchain projects?✅ What is the Blockchain Trilemma and why is the Assessment Framework based on it?✅ What metrics does each dimension of the Blockchain Trilemma contain?✅ How to apply the Assessment Framework - A simple guide.✅ Example assessments that show you step-by-step how to apply the Assessment Framework✅ A list of resources to research the metrics and to conduct your own assessment of Layer1 blockchains. 💎 How you benefit from the book:💎 You gain fundamental blockchain knowledge you would need weeks or months to collect the information from websites, Youtube and Twitter💎 You have a go-to framework that provides an understanding and gives an indication of the status quo of Layer1 Proof of Stake Blockchains, regarding their degree of decentralization, scalability, and security 💎 You have guiding principles and fundamental metrics at hand that helps you when it comes to making investment decisions. (because conducting such a quantitative assessment before making an investment decision should be a prerequisite for everyone in crypto for the long-term game.)💎 The provided example assessments of major Layer1s already bring you way ahead of 95% of the people in the space who just follow the next best Crypto influencer when it comes to their investment decisions.📖 What you will get - A sneak peek into the outline of the bookIn chapter 1 we will dive into the crypto assessment and shed light on why a metrics-based assessment framework is important.Chapter 2 deconstructs the development of the L1 Proof-of-Stake Blockchain Assessment Framework based on the Blockchain Trilemma and provides a detailed step-by-step guide and explanation of what metrics the Assessment Framework comprises.Chapter 3 provides example assessments of major Layer 1 Blackchins and demonstrates the practical application of the developed framework. Finally, Chapter 4 provides you with the most basic resource links to apply the Assessment Framework to conduct your own assessmentThis Assessment Framework has been deliberately designed to be as simple and accessible as possible so that also crypto beginners can work with it. I hope it will help you to start analyzing the fundamentals of existing or upcoming blockchain projects and to make more informed decisions.🎁 After you buyAfter you purchase the eBook, the download link will take a few minutes to come to your email inbox due to PDF stamping.

Cardano showcasing network resiliency after a close call

What happened?

Recently, the Cardano network faced a hiccup when over half of its nodes went offline for a brief period.

The incident, which occurred on 22.01.2023 at 00:09:00 UTC between block 8300569 and 8300570, was caused by a transient anomaly that affected relay and block-producing nodes. However, edge nodes appeared to be unaffected.

It was triggered by a transient anomaly causing one of two reactions in the node; some disconnected from a peer, and others threw an exception and restarted.

What exactly caused this network hiccup?

From early analysis, the event was caused by a transaction bug.

According to Andrew Westberg, a veteran stake pool operator with extensive experience, the root cause would be difficult to find as the data related to the event is likely gone. 

How the incident affected the network and its users?

Although the incident caused a temporary interruption in block production and resulted in a portion of the network falling out of sync, IOG stated that the systems performed as anticipated.

And the overall impact on the network was minimal, similar to delays that can occur during regular operations and at epoch boundaries.

Discussions around the Ouroboros Genesis in the context of network hiccup

Although the network recovered from the event quickly without any serious impact, there were discussions about the capabilities that Ouroborus genesis could bring during such a future event.

Introduction to Ouroboros Genesis

Ouroboros Genesis is the next anticipated upgrade that introduces a property known as Dynamic Availability to Cardano.

This feature allows the chain to automatically adjust and maintain security in the event of a drastic change of network participation, such as an outage.

The protocol is designed to address one of the main challenges faced by PoS-based blockchain protocols, which is the inability to realize the ledger functionality under dynamic availability in the same way that Bitcoin does (using only the information available in the genesis block).

How Ouroboros Genesis Works?

The Ouroboros Genesis introduces a novel chain selection rule.

The rule enables new or offline parties to safely (re-)join and bootstrap the blockchain only from a trusted copy of the genesis block without any additional advice or assumptions regarding past availability.

This means that even if a large number of nodes went offline, the network would be able to adjust and remain secure. The protocol is also designed to be independent of both the maximum network delay and the minimum level of availability, making it more resilient to outages.
