Homework on Ethereum Intro

Ethereum 101
#241
  1. Just a static Website: text, picture and links
  2. It is a blockchain based program which cannot be altered and excludes the necessity of trusting a third part. It is basically: when this condition is fulfilled, this will happen.
  3. Both parts can verify that the conditions have been met.

  1. What was Web 1.0?

  2. What is a smart contract?

  3. How is transparency achieved with ethereum code?

First internet with only text and image links. after that it was internet 2.0 and with Javascript, more dynamic chat etc.

Its codes written,programming that runs on the eth blockchain, and its decentralized.

Eth smart contracts are open for all to see with no third party.

What was Web 1.0?
What is a smart contract?
How is transparency achieved with ethereum code?

  1. Web 1.0 was the basic form of the internet in the early days, such as websites using basic HTML, and plaintext emails.

  2. A smart contract is a trustless software program written on the blockchain. It can say, for example, that one person will receive money deposited in the smart contract if and only if certain conditions are met.

  3. Because the smart contract is written into the blockchain, everyone can read the contract on that particular block. It is a trustless and transparent system that can be verified at anytime by anyone.

  1. What was Web 1.0?
  • Static sites (HTML, CSS).
  1. What is a smart contract?
  • A smart contract has a set of rules that it must follow, giving it a credible transaction, without the use of third parties.
  1. How is transparency achieved with ethereum code?
  • Everything is verifiable within the blockchain giving the smart contracts complete transparency.

  • From a consensus perspective, how is Ethereum different from bitcoin?
    -> both (still) PoW
  • How are smart contracts executed in Ethereum compared to in a normal computer?
    -> Smart Contracts in Ethereum are program’s executed over a decentralized network.
  • What are the benefits of executing the code on many nodes instead of just single computer/server?
    -> No single point of failure.Not stoppable. Immutable.

  1. Web 1.0 was the first level of internet, where websites were static and could only share text, images and links.
  2. A smart contract is a programmable contract that operates according to rules that cannot be changed once it is deployed.
  3. The code of the smart contract is visible in the blockchain.

1.Ethereum enables to deploy apps into the network.

2.Ethereum uses EVM to execute code written in Solidity or Vyper to prevent CPU from malicious apps deployed to the network. Normal computer uses CPU directly.

  1. More secured, transparent, trustless apps.

Web 1.0 was static. It was basic text, images and links. All you could do on web 1.0 was read and share info.

Smart contracts can distribute money based on conditions written in the contracts code.

Once a smart contract is deployed its unstoppable. The code of a smart contract is open source.

  1. What was Web 1.0?
    Web 1.0 was the start of the internet we know of today except it didnt have Javascript that allowed many more features to be implemented. the web at that time was simply static web pages with text, pictures and links. (I actually use to make these sites)
  2. What is a smart Contract?
    a smart contract is basically a program built on a second generation blockchain that allows the removal of an intermediary and therefore removes the trust factor. Anyone can write a “smart contract” for any reason and can deploy it on the blockchain.
  3. How is Transparency achieved with ethereum code?
    Transparency is achieved because ethereum code is fully transparent and open source and the smart contract code can be verified by others so that the community as a whole knows exactly what was written and what the end result should be.

1, Web 1.0 is a static web, it has only text, image and links. We can see it on some basic website without front-end scripts.

2, Smart contract is basically a piece of code which own value and it decides itself what to do with that value. For instance, we can deploy smart contact on Ethereum blockchain . once they have been deployed, nobody can change them.

3, Ethereum achieved transparency by making availabe the blockchain public for everyone, it is secure and trustless without any authority or middle man.

  1. The first version of websites where you can only read and share information
  2. Smart contracts allow the performance of credible transactions without third parties. These transactions are trackable and irreversible.
  3. Everyone can see what’s happening. For example, everyone can track what’s happening to the government’s money.

Hi,
1, First “wawe” of web pages- user interaction is very limited and web page cannot interact with user
2, Its basically programable money.
3, Eth code and smart contracts are visible to everyone on the blockchain.

  1. static web to share information and not to interact with it
  2. Blockchain based contract, which cant be changed after deploying it on the network
  3. everybody can see the status quo of contract on the blokchain

  1. What was Web 1.0?
    Web without JavaScript: static and inflexible. Mostly text, images and links.

  2. What is a smart contract?
    Small pieces of program, which is unstoppable an transparent. This program is doing, what is has to do without any third parties.

  3. How is transparency achieved with ethereum code? You can see any transaction on the blockchain and it’s not able to change it. You can’t change a smart contract .

  1. What was Web 1.0? A simple Static page where you can add Text, Image and Link Only good for read and Share
  2. What is a smart contract? A contract that need to be program with Solidity Language and can be distributed directly to the blockchain, where no body can change it, fully trustable, secure, transparent and No middle man …
  3. How is transparency achieved with ethereum code? everyone have acces to the code and read it ( Open source )

  1. This was the first widely adopted “version” of the internet. It consisted of mainly static images and html and there wasn’t much advanced activity and actions that could be performed on the internet.
  2. This is essentially just code that runs on the ethereum blockchain. These can be deployed by any user.
  3. All code is visible for anyone to see and this code essentially translates to specific rules which perform certain actions. We can then use the rules to define how we want certain organisations/governments to behave and there is no way for corrupt officials or insiders to modify/break these rules in order to enrich themselves or their peers.

  1. Web 1.0 was an internet collection of “static” information that was not dynamic and not interactable with users.

  2. A smart contract is a piece of code that can determine when and how to sends funds based on a list of criteria.

  3. Transparency is achieved with Ethereum by listing the rules and transactions publically which anyone on the network can see.

  1. Web 1.0 are static web sites.
  2. Smart contract is small piece of code witch decides what to do in moment when it meets criteria for it’s execution.
  3. Transparency is achieved because we can’t change smart contract, once it’s deployed to network everybody can see and verify that.

Web 1.0 was exciting! It was the first time that the public could communicate across long distances in ways previously unknown. At that time people actually talked to each other over the phone using land lines. It cost a lot - for each minute - when you wanted to speak to someone living a long distance away. Then, there weren’t any options for wireless contact, unless you could afford a satellite phone which were very big and clunky and you had to get used to the time delay when hearing the other person’s message.

Web 1.0 websites were so cool because this thing called a hyperlink could take you to places you’d never been before all in a few seconds. Computers were way bigger and dare we say dumber, but there were no ‘moving parts’ on the screen like videos or interactive anything. There was text, links and perhaps images, mostly small grainy pictures.

When javascript (JS) was released to the world it took a little while to catch on but it gave motion to the computer screen. Websites could react to your input and remember that you’d visited before showing content tailored to your preferences. We called it Web 2.0 and that made websites dynamic. Looking back to Web 1.0, yes those websites look boring when compared with modern websites that allow us to interact with each other in real time.

Now, when we’re discussing programmable money, we’ll say Web 3.0…and we’re all here to imagine what we can do with it!

A smart contract is some code written in the language called Solidity and deployed on ethereum. Smart contracts are like programmable money. Funds can be sent, using the ethereum blockchain, to a smart contract to perform some task. When the appropriate conditions have been met to complete the task, the smart contract will spend the funds as directed in its code. It’s a trustless system because we can all see the code and we can see who is sending and receiving the funds.

Ethereum code is transparent as it is part of the public, unstoppable blockchain. Anybody can see what has been written in the smart contract and that makes it transparent. No one can change the smart contract once it’s in a block on the chain because of the hashed and protected links that connect the blocks of transactions on the ethereum blockchain.
