Homework on Ethereum Intro

Ethereum 101
#3190

1- Web 1.0 were static websites that could only contain information such as texts and images, without any interaction.
2- smart contracts are self-executing contracts between buyer and seller written in code in a blockchain network decentralized, where this code controls the execution, and transactions are trackable and irreversible.
3- Transparency is achieved by removing middle man and and anyone can verify the contract on the network.

  1. What was Web 1.0?

    Web 1.0 consists on static Websites that only allow to read and share information, like text, images or links.

    As a side note, programmable application was only available after the introduction of Web 2.0, with JavaScript language.

  2. What is a smart contract?

    Smart contracts are small pieces of code that run on the ETH blockchain, by using Solitidy programming language.

  3. How is transparency achieved with ethereum code?

    Transparency is achieved by the following features:

  • Available for everyone to see the complete transaction - From the sender to the receiver, along with the amount and conditions applied to the smart contract.

  • Programmable money - It owns the money and decides what to do with it, without a middle man.

  • Immutable - It’s impossible to change or shut it down after deployment.

    This allows for virtually infinite applications, mainly in government projets, which can reduce corruption, or even ends it.

  • Static website that displays basic information such as texts, images, and links.
  1. What is a smart contract?
  • An instruction programmed into the blockchain that automatically executes itself once the conditions are met
  1. How is transparency achieved with ethereum code?
  • Ethereum smart contracts are written and deployed onto the blockchain where it can be viewed by the public and verified

1. What was Web 1.0?

Static html web sites, it was only possible to show information

2. What is a smart contract?

It is code in blockchain that determines what will happen in certain time or if certain conditions are met. The way how a smart contract was created / coded cannot be altered afterwards.

3. How is transparency achieved with ethereum code?

Ethereum is open source, the transactions and smart contracts are publicly available in the blockchain.

  1. The Web 1.0 was static page with text, image and link.
  2. A Smart Contract is a dynamic and programmable contract run on blockchain technology which once deployed, nobody can shut it down or change it.
  3. The Ethereum code is public and can be seen by anyone.

  1. The first websites that could only display text, links and images and could not be adaptive based upon who was using the website.

  2. A smart contract is a programmable condition for the exchange of cryptocurrency. X will happen to the money if condition Y is met.

  3. The code is open sourced so anyone can look at it and the smart contracts cannot be changed once they are set.

1.What was Web 1.0?
static websites- text, images and links, Internet with no Java script.
2.What is a smart contract?
Small pieces of code that can be programed and deployed on to the blockchain.
3. How is transparency achieved with Ethereum code?
Open source code, everyone can see. Trustless, its all in the math so you trust the protocols not the people. No 3rd party, you create your own contracts, no way to stop it unless written in the code.

1.From a consensus perspective, how is Ethereum different from bitcoin? ETH uses balances and was the first to implement smart contracts using ETHash. BTC uses UTXOs, SHA-256 and both (ETH & BTC) have PoW.
2.How are smart contracts executed in Ethereum compared to in a normal computer? Smart contracts run in the Ethereum virtual machines, they are decentralized to the miners who execute the smart contracts.
3.What are the benefits of executing the code on many nodes instead of just a single computer/server?
It’s more secure because everyone can verify it and run it correctly.

  1. What was Web 1.0?

Websites that were static, had only images, text and sometimes links could not include chats, comments, and other types of user interactions.

  2. What is a smart contract?
    A smart contracts are small pieces of code that are run on the Ethereum blockchain. They can hold currency and can be programmed to do whatever we want.

  3. How is transparency achieved with ethereum code?
    No one can delete or alter how a smart contract should behave. By having transparency, people trust the math and trust how smart contracts are written instead of a person. Don’t trust Verify :heavy_check_mark:

  1. web 1.0 is the first version of Internet which looks same for all with same content. It doesn’t vary based on user/account.
  2. smart contract is an immutable, transparent and deterministic software which runs on EVM. It runs only when a TX initiates it. A smart contract can’t be altered once deployed but it can be deleted if author programs it with SELFDESTRUCT functionality. Also smart contracts are single threaded meaning more than one smart contract can’t be executed parallely. A smart contract will have access only to TX which initiated it and some nodes. It can’t access real world data.
  3. Ethereum code is accessible to all and is everyone can see what is happening, how money is transferred. Even if a smart contract is deleted, the TX history doesn’t get deleted as block chain is immutable. All this make transparent and trust in math.

Web 1.0 was a static with just text and links available. There was no JS to allow for chats, social media and sharing info.
A smart contract are small pieces of code that are the basis of ethereum blockchain. Anyone can program a smart contract but once it’s programmed it’s transparent and can’t be changed. Smart contracts can be programmed to do whatever you would like them to do. eg. programmable money.
Anyone can see the code at anytime, that’s been created for a smart contract therefore making it all very transparent.

  1. Web 1.0 encompasses static websites

  2. Smart contracts are pieces of code that run on top of a blockchain that can be programmed to handle money and many other things that involve middlemen.

3.The transparency comes from the fact that smart contracts and tx on the blockchain are viewable to everyone.

  1. Web 1.0 was a network of static text, images and links.

  2. Smart contracts are written code, deployed on the ethereum network, which are solved, paid out when the programmed requirements are fulfilled.

  3. It is transparent, because everybody can see, what is happening with the money and the contracts, nobody can interfer with contracts.

  1. What was Web 1.0? It is the first version of the internet. Just information on a page with no interaction.
  2. What is a smart contract? A smart contract are instructions of code that execute on the blockchain when specific conditions are met.
  3. How is transparency achieved with ethereum code? It is achieved because of the smart contract. The contract doesn’t allow anyone to go back and change things. All parties have the same records of the transaction.

Static websites that were optimized for lower bandwidth connections and mostly with a focus on making academic research accessible on the internet.

A smart contract is a trust-less computer program that executes multiple times on multiple nodes in a decentralized network and the state of the contract is stored on each node so no one party has control of the contract.

The smart contract code is public and auditable by any party by using blockchain explorers such as etherscan.

  1. The first version of the web which consists of static websites, only containing links, images and text.

  2. A smart contract is a program code in the blockchain where funds can be held between parties until a goal or requirement is reached.

  3. With decentralized open source software, blockchain contracts can be viewed and verified by anybody, making it trustless.

  1. Web 1.0 is a static website with no interaction (life before scripting)

  2. Smart contracts are small pieces of code run on the Ethereum blockchain, programmed that “if” something happens, “then” complete and execute the following task

  3. Transparency is achieved with the Ethereum code by making all data in smart contracts available and visible for all
