  1. What was Web 1.0?

    • First version of web content on internet , where only static pages with text and images were possible.

  2. What is a smart contract?

    • A piece of code that manage how blockchain works under specific circumstances

  3. How is transparency achieved with ethereum code?

    • Because it uses blockchain which is public, so anyone can verify and track transactions and information processed on it

1/ It was the internet that did not have JS which made it quite basic

2/ It is something that you program it and once you deploy it over the network it is unstoppable and unalterable, like BTC, you can also have money and decide what to do with it

3/In the same way as BTC, thanks to the BlockChain, how it works and the mathematics behind it, in addition to being de-centralized, it works alone

  1. it only allowed for static sites with links, text, and images
  2. smart contracts allow you to program money and how it moves/behaves
  3. all of the nodes on the blockchain are linked and will know when any new blocks are created and what information is on them

  1. What is Web 1.0

Web 1.0 is a static form of web, where we can only have text, images and links.
Different from Web 2.0 where we can have a dynamic and programmable functions enabled by the development of Java Script, giving us the ability to have chats, accounts, social media, etc.

  1. What is a Smart Contract?
    Smart contracts are small pieces of codes running on the Ethereum network. We can use Solidity to write these smart contracts. Smart contracts are unstoppable, and transparent, where everyone can see the transactions (sending/receiving). Smart contracts are based on the preset rules and can only be executed based on the rules listed in the contract. This contract cannot be changed (see blockchain & bitcoin proof of work and mining). Hence, smart contract allows deals and businesses to be done without needing a middle man or trust.

  2. How is transparency achieved with the ethereum code?
    Transparency is achieved with the ethereum code where everyone can see the transactions that are happening, and these transactions cannot be reversed or modified due to the way the ethereum blocks are connected in the blockchain.

  1. What was Web 1.0?
    Web 1.0 was the Internet before Javascript.

  2. What is a smart contract?
    A smart contract is a small piece of code for programmable solutions on the Ethereum blockchain.

  3. How is transparency achieved with Ethereum code?
    Anyone can audit deployed contracts and transactions on the Ethereum blockchain.

  1. Web 1.0 was static websites. You could only transfer information, post links, images, etc. It was the internet without JavaScript.
  2. A smart contract is a program that can own and decide what to do with money and assets, without the interference of humans (on its own).
  3. Transparency was achieved with the ethereum code because now many forms of transactions can be done on smart contracts, which can all be traceable and verifiable.

  1. Web 1.0 is the original creation of the internet with basic websites that only support basic text, images and links.

  2. A smart contract is a program created on the blockchain using solidity and can manage and own money and can never be turned off.

  3. The code for all programs on the ethereum blockchain is public for all to see, therefore they can be verified 100% by assuring the code is up to par.

  1. What was Web 1.0?
    Static content, no interaction with the data. You can read it, and jump to the next data source.
    HTML and some basic cosmetics.

  2. What is a smart contract?
    A small code on the blockchain, which is public, transparent and unstoppable as it runs on the chain. No middleman, company or government can alter the output of the code. It’s a trustless entity, which cannot be bribed to favor you.

  3. How is transparency achieved with ethereum code?
    Smart contracts are public. Anyone can read and verify them and the output of the contract is recorded on the chain.

Homework on Ethereum Intro - Questions. (Questions were updated on Dec 3 2019)

1. What was Web 1.0?

Web 1.0 was the first version of the World Wide Web, where it just consisted of static text and links to other pages.

This is distinct from Web 2.0, which allowed users to interact with and personalize the content of a site through the implementation of the Java programming language.

2. What is a smart contract?

A smart contract is an unstoppable packet of code, a collection of instructions that runs on a blockchain network, such as Ethereum, Lisk, Eos, and Neo.

On Ethereum (which is a network of nodes run by the user’s computers), smart contracts are coded in Solidity (which is an unlimited and Turing complete programming language), and are executed by the nodes via the EVM (Ethereum Virtual Machine).

3. How is transparency achieved with ethereum code?

Each node in the Ethereum network stores a copy of the distributed ledger of transactions (which addresses sent how much value to what other addresses), and these are openly viewable via blockchain explorers such as Etherscan.

The fact that these records are stored in a decentralised manner also makes blockchains hacking resistant, as there is no central (and therefore more vulnerable) database that can be attacked and potentially compromised.

  1. Static web side
    2)Smart contract is a self executing contract with the terms of the agreement which is intended to automatically execute,control or document legally relevant events and actions according to the terms of the contract or agreement .
    3)must reach network consensus, by executing code and distributed on the network,the contract is censorship resistant,traceable and irreversible.

  1. A static website without interaction, read only web.
  2. Small pieces of code on the Ethereum network, programmed with Solidity.
  3. Because the smart contracts are on a public chain, everyone can read it. And because it is trustless, no need to trust a middle men.

1 Web 1.0 was initial internet/static/text/image/link
2. Smart contracts are small pieces of code that run on the Etherium blockchain
3. Transparency is achieved as you can see who is writing or sending the smart contract and who is receiving it.

  1. What was Web 1.0?

Web 1.0 had the capability of display information like text and images but had no way for the user to interact with a website.

  1. What is a smart contract?

A smart contract is a small programmable code that interacts with the blockchain. Smart contracts on ethereum are written in a language called solidity.

  1. How is transparency achieved with ethereum code?

Because the smart contract sits on the public blockchain its functions can be read and audited by anyone, this is what makes them so transparent and allows us to trust them in a trust-less way.

  1. Web 1.0 was when we had only statics websites.we only had texts , images anda links with 1.0 .

  2. Smart contract is a small piece of code that runs on ethereum blockchain .

  3. With ethereum code once the smart contract is deployed cant be change or else happens the same as happens on bitcoin blockchain all the blocks get modified and you can see it. Everyone can verify it , no middle man.

Web 1.0 was pre-javascript static web pages.

Smart contracts are small lines of code that can hold assets until programmed criteria is met.

Etherium code is transparent because it allows nodes to see a smart contract’s content.

  1. What was Web 1.0? is referred to the term of the first version of the www that was a simple static website.
  2. What is a smart contract? is a computer program that authorize what ever you want to agree with the user, for example money transactions. send money, program some rules on how withdraw the money, this is just an example.
  3. How is transparency achieved with ethereum code? by using smart contract, Blockchain, POW, etc.; similar Bitcoin concept.
