Implementing Vitalik’s Vision | Ethereum Foundation Blog

The core concepts were proven last summer when lead developers Vitalik Buterin, Gavin Wood, and Jeffrey Wilcke launched a series of proof-of-concepts (PoCs) in Python, C++, and Go, but a lot of engineering effort has gone into strengthening these implementations. . We’re all hoping to release a stable command line client, and issues flagged by external audits are being addressed as they are discovered. A general release will follow soon after this process is complete. Meanwhile, the rest of the ecosystem continues to evolve into more sophisticated versions.

One of the challenges of a project of this scope and complexity is simply agreeing on certain things. Translating human abstractions into code is a difficult task. Even the words we choose It affects many different ways to express ideas in code. You can build more on these core ideas and remove ambiguity by improving the underlying specifications as you experience in practice how reality meets theory. It all pays off as the team shares a clear, well-understood vision that must be effectively translated to other developers in a variety of disciplines.

Number of Git commits over time

A diverse test suite that complements this adds an important level of confidence that various implementations conform to the specification. On the consensus side, we used a series of VM and state tests to simulate known outcomes, and added randomization and fuzzing to increase this test space. A series of system and networking tests are also run to ensure that clients communicate in the expected way or respond predictably to specific networking scenarios.

Not only are the tests designed for success, but all kinds of error conditions are fed into the test suite to ensure that known errors (such as running out of gas or suddenly losing connection to a peer) are reported correctly. What this means is that when there is a change in customer behavior, decisions are made based on data and metrics rather than theory and intuition.

Graphing node connections allows you to visually inspect the state of your network.

In addition to testing the core components, we started implementing tests for the outer layers to ensure that the client responded to numerous calls to the underlying system in the same way, using readily available JSON. This specification is linked: From the wiki Facilitates implementation and communication across diverse teams. This helps ensure that what’s in our heads can be reliably translated into code, and that all of this can be tested and audited.

All of these improvements are important to the health of the overlay ecosystem and help shed light on very nuanced issues. In addition to improving the core virtual machine and serialization layer, a security audit has been initiated using a third-party company with experience in decentralization and encryption technologies.

A high-level overview of the development effort.

So how is all this basic technology exposed to the average user? For the Frontier release, we aim to release stable binaries on the major operating systems (Mac, Windows, Linux). The main interface mainly consists of a command line client, an interactive JavaScript console, and JSON-RPC. go-ethereum recently renamed this client to “Geth”. mass effect and old english.

Using the command line client is a process that is familiar to many people. For example, you can create a new account using: new geth account, at which point the program will ask you for a password to secure your account. To start geth as a miner, simply call geth with parameters like this: geth – mine. This is a great way to start interacting with the system, but it has its own limitations. For example, how do I pause mining after I start it?

Using Geth’s interactive JavaScript console

For more useful ways to control your program, Geth has a JavaScript console supported by: JavaScript API. Get started with a simple command: Geth Console. With Geth interactive console, provides user-friendly JavaScript scripting to control the system from the terminal. For example, to learn more about your local node, run: admin.nodeInfo().

This control is driven in part by: ethereum.js, a JavaScript library that helps provide a friendly interface not only for consoles but also for DApps. This relies on well-documented documentation. JSON-RPC Interface for automated processing or integration into existing infrastructure. Work is ongoing on many of these components, as strict efforts are made to ensure that implementations use the same language and are as generally compatible as possible.

Quick view of build status

Of course, all of this is built publicly on GitHub and includes various continuous integration aspects such as automated builds and reporting to major platforms. This is not a program that defines specifications. These are specifications that have been implemented and cross-tested between machines and humans around the world.

At the same time, work is underway on several other components of the ecosystem, including GUI interfaces for Mist (DApp browser) and Mix (IDE). Many of the tools we use and build are new, so they sometimes require upstream patches to ensure everything works as expected. This is a huge benefit to any open source development and, in fact, one of the many positive byproducts of all the time spent engineering software. The wait may seem long, but progress and continued confidence in the overall system is steadily increasing.

In addition to the technical content of development, our communications team has continuously interacted with the community to produce public educational materials such as tutorials and videos. Our administrative staff also helps process payments and ensures compliance with various local laws, including boring things like employment taxes.

Who needs sleep?

Participating in the Ethereum project has been a special experience full of excitement. How did it start? idea Just over a year ago, a remarkable engineering effort was born, led by experts who implemented all the infrastructure needed to build a revolutionary distributed application platform.

When Netflix was introduced Chaos MonkeyThey argued, “We realized that the best defense against major, unexpected failures is to fail often. By failing frequently, we force our services to be built in a more resilient way.”. During the process of developing Ethereum, we experienced firsthand the benefits that come with Ethereum. Continually putting a strain on the system.

It’s a great honor to be tasked with creating the very platform you dream of, but we create it because we want it to exist. Thank you for your patience as we think, sleep, and eat. dog food platform. We are more excited than anyone to see what kind of DAapps will be released after the mainnet launches!
