Homework on Ethereum Intro

Ethereum 101
#1146
  1. Web 1.0 was the first version of the Internet which had only limited features available such as posting a text or an image, and had no advanced features such as those which have ever since been enabled by the use of java script.
  2. A smart contract is a small piece of propgramming that is run on the ethereum blockchain
  3. The key feature of any blockchain is immutability so that no transcation may be amended once posted to the network. The ethereum code also benefits from this feature by allowing to keep track of any arrangement to be programmed into a smart contract so that it could not be changed, or otherwise tampered with, after its original posting

  1. What was Web 1.0?
    Web 1.0 only had static websites and was very limited in use case. You could really only send text, images, and links before adding javascript and moving to web 2.0.
  2. What is a smart contract?
    Smart contracts are solidity programs that are deployed to the blockchain. In these contracts you give the smart contract an input, tell it what to do, and it gives an output based on the code.
  3. How is transparency achieved with ethereum code?
    Transparency is achieved with ethereum code because it is trustless. There is no need for middle men and no one can change the code of a smart contract once it is put on the blockchain.

  1. What was Web 1.0?

The first version of the internet where websites were static. They could manage text and images but little more.

  1. What is a smart contract?

A smart contract is a piece of code that runs on the ethereum blockchain. It can be programmed so that it will take an action on your assets if certain conditions are met.

  1. How is transparency achieved with ethereum code?

The code is available for anyone to view. Nobody can reverse or change smart contracts which promotes the idea of trusting in the technology. This allows participants to do business with strangers as there is no need for intermediaries.

  1. Web 1.0 was the first version of the internet and it was static containing only text, images and links.

  2. A smart contract is a piece of code that allows you to program your money.

  3. Anyone can see the code behind the smart contract. Once you program it you canā€™t modify it.

  1. Web 1.0 was the initial offering of the WorldWide Web. It was text based, had images, and could send and receive messages.
  2. A smart control includes agreed upon rules by both parties which then executes its code over its lifetime without being changed.
  3. Smart contracts are public so anyone can review what the smart contract does. The blockchain as with bitcoin is also public.

1 - Both use POW but Bitcoins require miners to solve a hash puzzle and Ethereum requires nodes to run smarth contrats through an EVM and agree on the results from ruining their codes.

2 - In a normal computer , CPU execute the code instruction from a program, Ethereum , the code is executed by EVM , the CPU executes the instructions that EVM directs it to. The smart contracts preventing them accessing the computerā€™s hardware.

3 - Provides a decentralised network essential for consensus protocols to work and eliminates a single point of failure scanario . Smart contracts become transparent and unstoppableā€¦

  1. What was Web 1.0?

no interaction, and no Java script allowed, so its non-dynamic pages, it is static

  1. What is a smart contract?

A code running on the Ethereum blockchain that will execute itself automatically if a set of predefined rules apply

  1. How is transparency achieved with ethereum code?

Same as Bitcoin, Everyone can see the blocks, and it is immutable

  1. Web 1.0 served static websites that could not be programmed to give unique experiences for different users.

  2. Smart contracts are applications on a blockchain that are capable of managing data

  3. You can program a contract that does not rely on trust because the contract will execute based on how it was written.

  • What was Web 1.0?
    Bitcoin is analougous to Web 1.0 a one dimensional product that could not do much than a few things that it did very well plain vanilla. Ethereum would be an upgrade to BTC because it could be possible to create more calculations and coding called contracts.
  • What is a smart contract?
    A smart contract is a form of a program that you can run with the use of the Ethereum Virtual Machine whereby you can do functions and different types of checks and balances programming.
  • How is transparency achieved with ethereum code?
    Transparency is achieved by the network being able to audit the lines of code of the smart contract and verifying the Ethereum Virtual Machine performed the function and viewing the results.

1.- It just text, images and links that can be shared.

2.- It`s a web more dynamic than web 1.0 that can program task be executed after some conditions have been fulfilled. For instance, I can create a smart contract that will release the balance for a child once turn 18 years old.

3.- As per math and technology, there is not human intervention that can modify how smart contract behave after been programmed, then can no be changed in favor to one person or another.

To clarify, smart contract is a computer protocol intended to digitally facilitate, verify, or enforce the negotiation or performance of a contract. Smart contracts allow the performance of credible transactions without third parties.

  1. Web 1.0 was an version of the web that was static. it was probably more one dimensional in that you could text maybe it could display an image and access pages through links. it wasnā€™t as interactive as the version we have now.

  2. A smart contract is a contract in the form of programable data, that cannot changed. it is transparent. and is unstoppable.

  3. Transparency is achieved with a smart contract once it is written it cannot be stopped nor can it be changed. it removes the middleman, and the element of trust is removed. also the information is readily available to see and understand.

What was Web 1.0?
Limited just to HTML, very limited embedded styling vs. separate CSS file that happened later with for more developed CSS2 and elaborate standard of CSS3, static-hosted websites from centralized servers, and no Javascript functionality on either webpages, even ajax, or server (i.e. node.js). Very limited functionality in terms of both webpages and what internet could be used for.

What is a smart contract?
A computer program in the form of an application that runs on Ethereum network nodes, often written in Solidity programming language, that is then compiled by the Solidity compiler to bytecode. The bytecode is then run by the EVM of each node and smart contract program instructions are executed on each nodeā€™s CPU.

How is transparency achieved with ethereum code?
Ethereum source code is open source and the blockchain that stores all confirmed transactions can be inspected just like in Bitcoin.

  1. What was Web 1.0?
    It was the beginning of internet era, where the web sites were static, they enabled the user to only read and share the content, there were no such functionalities such as chat or possibility of multiple accounts.

  2. What is a smart contract?
    A piece of code that runs on Ethereum blockchain. It can own money and decide how to handle them based on predefined condition in the code without any intermediaries.

  3. How is transparency achieved with ethereum code?
    No central authority that could intervene or change the behaviour of the smart contract, it canā€™t be shut down, the transactions are transparent.

  1. Web1.0 is the first part of the internet development, where you have a static website with a few images and links.
    2.A smart contract is a small piece of code that runs on the Ethereum network.It is unstoppable and transparent. It is a way of programming money without intermediaries and third parties.
    3.With Ethereum code transparency is achieved by seeing the transactions, who is sending and receiving money. Also once a smart contract has been deployed thereā€™s no way to change it. Nobody can change how a smart contract behaves.By trusting math and technology, we can do business with strangers. By removing the element of trust, the code of a smart contract becomes transparent.
