Mastering Ethereum


The story of the idealists, technologists, and opportunists fighting to bring cryptocurrency to the masses.

In their short history, Bitcoin and other cryptocurrencies have gone through booms, busts, and internecine wars, recently reaching a market valuation of more than $2 trillion. The central promise of crypto endures—vast fortunes made from decentralized networks not controlled by any single entity and not yet regulated by many governments.

The recent growth of crypto would have been all but impossible if not for a brilliant young man named Vitalik Buterin and his creation: Ethereum. In this book, Laura Shin takes readers inside the founding of this novel cryptocurrency network, which enabled users to launch their own new coins, thus creating a new crypto fever. She introduces readers to larger-than-life characters like Buterin, the Web3 wunderkind; his short-lived CEO, Charles Hoskinson; and Joe Lubin, a former Goldman Sachs VP who became one of crypto’s most well-known billionaires. Sparks fly as these outsized personalities fight for their piece of a seemingly limitless new business opportunity.

This fascinating book shows the crypto market for what it really is: a deeply personal struggle to influence the coming revolution in money, culture, and power.

Idealism, Greed, Lies, and the Making of the First Big Cryptocurrency Craze

The Cryptopians


Tokens - often referred to as cryptocurrencies - can represent anything from an asset to an access right, such as gold, diamonds, a fraction of a Picasso painting or an entry ticket to a concert. Tokens could also be used to reward social media contributions, incentivize the reduction of CO2 emissions, or even ones attention for watching an ad. While it has become easy to create a token, which is collectively managed by a public Web3 infrastructure like a blockchain network, the understanding of how to apply these tokens is still vague.

The industry keeps referring to “Blockchain” as different from “Bitcoin,” creating an artificial divide that is often misleading. There seems to be too little understanding about the fact that Bitcoin is a blockchain network, which is (a) globally managed by people who mostly do not know each other, and (b) enabled by the consensus protocol that (c) incentivizes all network actors for their contributions with a native token. The governance rules are tied to the minting of a native blockchain token. The Bitcoin token can, therefore, be seen as the currency of a distributed Internet tribe, called the Bitcoin network, where network actors are rewarded with Bitcoins, just as the Ether is the currency of the distributed Internet tribe Ethereum network, or Sia is the native currency of the Sia network. The Bitcoin network and other distributed ledgers all represent a collectively maintained public infrastructure and are the backbone of the next generation Internet, what the crypto community refers to as the Web3.

This book attempts to summarize existing knowledge about blockchain networks and other distributed ledgers as the backbone of the Web3, and contextualize the socio-economic implications of the Web3 applications such as smart contracts, tokens, and DAOs to the concepts of money, economics, governance and decentralized finance (DeFi).

## What is a smart contract?

Smart contracts are the backbone of decentralized applications (DApps) and Web3. A smart contract is a simple program that lives on a blockchain network (such as Ethereum). They're actually not that smart. And nothing like a (legal) contract. They’re more like an executable piece of code that requires input or an trigger from an external source. They can validate those input conditions and if correct, execute their own logic to update the state on a blockchain.

## Benefits

They often serve the following purposes:
- Store and maintain data
- Manage relationships with users, or other contracts

Benefits of smart contracts are
- Immutable - once deployed none can change them
- Composable - they’re public and anyone can interact with them, or build on top of them. Much like public APIs

## Resources

The following resources have been the most popular resources on the site for a long time. These are all highly recommend to start learning about Solidity


### 1. Official Solidity website
The most obvious resources is ofcourse the official website and documentation of the Solidity team itself. The Solidity team covers all the core concepts and fundamentals of Solidity and smart contracts in general. Highly recommended

https://soliditylang.org/


### 2. Solidity by Example
The second one on the list is Solidity by Example. A great collection of more practical examples, incl. source code and supporting videos.

https://solidity-by-example.org/


### 3. CryptoZombies 
CryptoZombies is an interactive school that teaches you all things technical about blockchains. A fun and interactive way to write smart contracts in Solidity by making your own crypto-collectibles game.

### 5. Smart Contract Best Practices 

Smart contracts are complex instruments that have the authority to allocate high-value resources between complex systems. Often working autonomously. With huge financial loss at risk. This makes them critical components in these systems. Development of such components requires thoughtful design, solid engineering practices, rigorous testing and a strong security mindset. This document provides a baseline knowledge of security considerations.

Odds are you’ve heard about the Ethereum blockchain, whether or not you know what it is. It’s been in the news a lot lately, including the cover of some major magazines, but reading those articles can be like gibberish if you don’t have a foundation for what exactly Ethereum is. So what is it? In essence, a public database that keeps a permanent record of digital transactions. Importantly, this database doesn’t require any central authority to maintain and secure it. Instead it operates as a “trustless” transactional system — a framework in which individuals can make peer-to-peer transactions without needing to trust a third party OR one another.

Still confused? That’s where this post comes in. My aim is to explain how Ethereum functions at a technical level, without complex math or scary-looking formulas. Even if you’re not a programmer, I hope you’ll walk away with at least better grasp of the tech. If some parts are too technical and difficult to grok, that’s totally fine! There’s really no need to understand every little detail. I recommend just focusing on understanding things at a broad level.

Many of the topics covered in this post are a breakdown of the concepts discussed in the yellow paper. I’ve added my own explanations and diagrams to make understanding Ethereum easier. Those brave enough to take on the technical challenge can also read the Ethereum yellow paper.

A guide to Ethereum smart contract security best practices

Smart Contract Best Practices

_This is part of our [Testing](https://github.com/ethereum/ethereum-org-website/issues/12746) epic from our Q2 roadmap._

## Description

We have implemented support for storybook to do testing on [ethereum.org](https://ethereum.org/). We would like to be able to catch visual regressions before they reach production, helping us build confidence so that we can improve stability of ethereum.org through a testing suite. The first phase of this will be implementing visual storybook tests on our suite of components. 

Below is the list of components in the ethereum.org repo, broken down by [Atomic design](https://www.uxpin.com/studio/blog/atomic-ui-components/#:~:text=Atoms.,Examples%20include%20buttons%20or%20forms.).

## How to contribute
If you’d like to help with adding stories for components, please follow these steps:

1. Read the [storybook documentation](https://github.com/ethereum/ethereum-org-website/blob/dev/docs/applying-storybook.md) for the project
2. Leave a comment here asking which component you would ke to work out. We will be going from the top of the list to bottom (Atoms to Pages).
3. We assign you to the file (by adding your handle next to the file name in the list).
    - Read and follow our storybook implementation guide for some tips & guidance.
    - **If you were assigned to multiple files** then create a separate PR for each component. It will make the testing and review process much simpler and more organized.
4. Once you finish it (PR merged), we’ll mark it as done.
5. Repeat!

## Components

### Atoms

In Atomic Design, as in chemistry, atoms are the basic elements that help inform everything. In the world of web applications, atoms are the foundational elements, such as HTML tags, fonts, animations, and color palettes. Web design “atoms” can also be less concrete. Examples include buttons or forms.

```[tasklist]
### Typeography
- [x] Headings

### Molecules

Molecules are the next-largest building block. Created by the joining of different atomic elements, molecules are complex by nature. Because they’re the product of various atoms, though, it’s possible to break them down, conceptually, into UI elements that are easier to digest. Examples of web design molecules include the things that become the backbone of the larger design system, such as form labels or input field.

### Organisms

Atoms combine to form molecules, and groups of molecules form organisms. In the world of Atomic Design, organisms are the UI elements that shape both the appearance and functionality of a website. They’re also the elements that start to impact user interface. The way a developer arranges molecules informs the site experience and the complexity of the finished product. Examples of organisms include logos, search fields, and main navigation which together may form a header organism.

### Snippets - composed components has use cases or references to display the same type of data
-  [ ] https://github.com/ethereum/ethereum-org-website/issues/13052
```

### Templates

At this phase of the Atomic Design process, we start to break with the chemistry analogy and shift back into the lexicon of front-end development, as a whole. Templates, then, are “organisms” strung together at the page-level or beyond. Templates, online atoms, organisms, and molecules, are highly concrete. They provide a fixed context for the more abstract pieces to fit and are responsible for pulling the site together into something resembling its final form. An HTML wireframe is an excellent example of a template.

```[tasklist]
### Templates - base pages to be used in creation of new content. They incorporate all of the components mandatory for the page

### Pages

Pages, finally, are the final element of Atomic Design. According to Frost himself, pages are the specific instances of templates. Pages are the most tangible element of all and are the places users spend most of their time. They’re also one of the most essential phases of the Atomic Design process since the final iteration of pages is where developers get to see whether the entire design system is effective or not. In short, the final appearance of the pages dictates whether the product design is ready to launch, or whether the developer needs to loop back and make changes to earlier UI design elements.

## How to contribute
If you’d like to help with adding stories for components, please follow these steps:

1. Read the [storybook documentation](https://github.com/ethereum/ethereum-org-website/blob/dev/docs/applying-storybook.md) for the project
2. Leave a comment here asking which component you would ke to work out. We will be going from the top of the list to bottom (Atoms to Pages).
3. We assign you to the file (by adding your handle next to the file name in the list).
    - Read and follow our storybook implementation guide for some tips & guidance.
    - **If you were assigned to multiple files** then create a separate PR for each component. It will make the testing and review process much simpler and more organized.
4. Once you finish it (PR merged), we’ll mark it as done.
5. Repeat!

### Describe the desired feature

For long call sequences, re-executing reverted transactions probably adds more overhead than it is worth, considering it is unlikely that tx level mutations will make the majority of them successful e.g. 99% of a call sequence with a length of 500 is failing. It would make more sense to shrink the call sequence some portion of the time to only include successful transaction and insert/extend

### Describe the bug

If you delete imports, Nuxt auto-imports do not work: 

for example works: 

```vue
<script setup lang="ts">
import { useAccount, useDisconnect } from '@wagmi/vue';

const { address, chainId, status } = useAccount();
const { disconnect } = useDisconnect();
</script>
```


not working: 

```vue
<script setup lang="ts">
const { address, chainId, status } = useAccount();
const { disconnect } = useDisconnect();
</script>
```

iCandy is running their own rollup that uses the same underlying infrastructure as zkSync hence contracts are compiled the same way. They have asked for support in our Remix Plugin and I think the only thing that needs to be implemented is a whitelist to support other RPCs and networks within Metamask.
Their network details:
name: zkCandy Sepolia Testnet
rpc url: https://sepolia.rpc.zkcandy.io/
chain id: 302
token: ETH
explorer: https://sepolia.explorer.zkcandy.io/

We should add a check in CI to ensure that within a task folder, the numbering of tasks is increasing and does not overlap.

ie. #200 currently introduces a new dir `tasks/sep/009-fpac-upgrade` which is incorrect since there is already a `tasks/sep/009-presigned-pause`. 

This happens easily due to race conditions between new tasks, so we should automatically check for it.

We can currently run Cairo tests through native with out `cairo-native-test` command in this repo. 
It would be even better to one day be able to run tests driven scarb through native, so  anyone managing their Cairo project with it could for example do `scarb test --with-native`.

A plan to integrate with scarb and see what changes it would require here would be the first step.
A plan on modifications to scarb would be the second.

When processing RPC requests, a node may request the caller to slow down by giving an [HTTP 429 response](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/429).

evmconnect does not seem to handle this response properly. The correct behavior would be to pause all RPC requests for some amount of time. If the response specifies a `Retry-After` header, than that should be respected, but otherwise a random delay (of a few seconds) can be selected.

Currently, evmconnect has a pretty aggressive retry behavior - so it continues to hammer the node even while receiving multiple HTTP 429 responses (which makes the situation worse and can result in being blocked from making further requests).

See https://github.com/FuelLabs/fuel-vm/pull/732#discussion_r1598922013:

```rs
    fn ecal<M, S, Tx>(
```

>Hmm, I think M, S, and Tx should be generics of the EcalHandler. Otherwise, the implementer doesn't have control over the constraints for these generics. The M: AsRef<Memory> + AsMut<Memory> is an example. What is he needs some contains over the storage?

I think there is room for improvement on our DCA. For example, the screenshot below shows how `rustc` considers: `A`, `T` and `f` to be dead, because no "live code" actually uses them.

![image](https://github.com/FuelLabs/sway/assets/83425/0d1eccd1-74dc-45b5-a8dd-14224cb6d27f)

We, on the other hand, consider the mere presence of impls enough for them to not be dead.

![image](https://github.com/FuelLabs/sway/assets/83425/f56a63d6-c658-4eb2-b2e0-22cd966c605a)

Remove the impl and we now correctly mark this as dead. But the error message is not as clear as `rustc`'s, which says the struct is never "constructed".

![image](https://github.com/FuelLabs/sway/assets/83425/88b5e92b-70ed-4280-a4cd-91eba193ea23)
![image](https://github.com/FuelLabs/sway/assets/83425/068cc7ff-36f8-4f71-9151-289e8f7f199f)

This is all done at `sway-core/src/control_flow_analysis/dead_code_analysis.rs` and seems a candidate for "good first issue".

Using reverts in predicates produces a panic as they are illegal. Using them in that context should produce an error at compile time.
