Web 1.0 was the first stage of the world wide web and was made up of static (non-interactive) sites connected by hyperlinks.

A smart contract is a piece of code that anyone can create and can hold money (value). They are fully autonomous, trustless and cannot be shut down by anyone. They are also often open source.

Just like with Bitcoin, Ethereum uses an open, trustless, ledger-based system where transactions are easily auditable by anyone, using sites like etherscan.

  1. What was Web 1.0?

A. Static websites that could show text, images, and links - but only read and share info.

  1. What is a smart contract?

A. Small pieces of code that run on Ethereum blockchain by using a program called “Solidity”.
Smart contracts are transparent, unstoppable, and no one can change it, or shut it down.
Smart contracts decide what to do with money. SC can be programmed and used without 3rd party authority, participation, or foul play.

  1. How is transparency achieved with ethereum code?

A. No censorship, it’s unstoppable, and totally decentralized from 3rd party changes or errors. Out put from code becomes unchangeable public broadcast.

  1. It was the greatest, freest time of the Internet when you could find something useful and also freely express yourself without being bullied for being politically incorrect. Websites were ugly but easy to read and navigate and hyperlinks led to other interesting external resources without a fear to harm SEO. Google used to be awesome back then, it really could find great things for you, not only the same stuff that you already know or have already searched for. But then something went wrong: Javascript opened the Pandora box by seducing users into a more interactive but less private and less intellectual world: and here we are encapsulated in our informational silos, tracked by hundreds of trackers and followed by annoying ads of pairs of shoes we thought to buy. I have no idea how I found Ivan on Youtube, it was a miraculous way out of my usual informational junk consumption routine.
  2. Smart contract a programmable money distribution rules.
  3. Ethereum, as bitcoin has an open-source code and all transactions are stored in the blockchain - everyone can see the transactions and the smart contract rules.

  1. The first iteration of the internet, where you had text, static images and possibly a link to another website.
  2. It is an agreement written in code.
  3. Transparency is achieved by removing the middle man, no need to trust each other. Just like in bitcoin transactions(smart contract) can not be changed.

  1. Web 1.0 was the internet before Java Script where you could only add text, images and links. No multiple accounts, chat, or social media.
  2. A smart contract is pieced of code that run on the ethereum network. These codes allow for the electronic handling of money without an intermediary wherein funds can be transferred to anyone, anywhere, when certain conditions are met.
  3. Transparency is achieved in the ethereum code in the same way bitcoin transactions are transparent. Meaning anyone who knows where to find the information and read the data set can tell what exactly this smart contract is coded to do. On top of this, not only is it transparent but also immutable, also in the same way Bitcoin transactions are immutable (having to find the hash number that is below target for the changed block, then doing this for all blocks in front of said changed block before the network drops your changed blocks as stale blocks.

  1. Barebones static websites, that hosted text/images/links only.
  2. Transparent, programmable condition-based contracts.
  3. The code is available for everyone to see, therefore all smart contracts and their conditions can be audited.

What was Web 1.0?

A static website you can not interact with. It can contains text, images or links, but not javascript code.

What is a smart contract?

A smart contract is a code program that is executed in the Ethereum blockchain without a middle man. It i programmed in Solidity language, and it can hold money until certain condition happens.

How is transparency achieved with ethereum code?

The code of the Smart contract is visible for everyone and we don’t have to trust a middle man or company, just the protocol.

Hi
To program a smart contract, do you use common languages ​​like java script, phyton, etc? Or are other types of special languages ​​used? Thanks

  1. Web 1.0 is a term used to describe the early stages of webpages, before programs such as Javascript were introduced. It allows for texts, images and links to be displayed and remains static.

  2. A smart contract is a coded program that allows for contracts to be submitted and executed without the disadvantage/potential for human error.

  3. Transparency is achieved by allowing parties to view who sends/receives transactions. Once a smart contract has been programmed, there is no way to alter or manipulate how the contract behaves.

Hope I did a good Job! Once again, feedback is appreciated! :grin:

  1. What was Web 1.0?

Web 1.0 refers to the first stage of the World Wide Web evolution. Personal web pages were common, consisting mainly of static pages hosted on ISP-run web servers, or on free web hosting services

  1. What is a smart contract?

A smart contract is simply a program that runs on the Ethereum blockchain. It’s a collection of code (its functions) and data (its state) that resides at a specific address on the Ethereum blockchain.

  1. How is transparency achieved with ethereum code?

All the data is transparent and available to be traced by anybody but the confidentiality can be achieved by encryption. In other words, the confidential information is saved on the blockchain in an encrypted format, and the keys of decryption can be shared only with authorized individuals.

  1. Web 1.0 was the initial iteration of webpage programming that only allowed for programming static websites that could simply display text, images, and links.

  2. A smart contract is a small piece of code that can hold money until a specific condition is met.

  3. Transparency is achieved with ethereum code because anyone can go in and see what is happening to the money, and the smart contract cannot be changed once it has been deployed.

  1. It was internet without JS and Flash. It was necessary to reload the page for any update from any side.

  2. Smart Contract is an fully autonomous application that runs on a blockchain. Smart contract can hold and release currency when certain conditions are met, cannot be stopped if it wasn’t programmed to and allows parties to interact in trustless manner without any third party involvement.

  3. All of the Txs and smart contracts are stored in a public blockchain and are immutable.

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

  1. What was Web 1.0?
    Web 1.0 is the first version of the Word Wide Web. It allowed a very static and passive user experience where the online surfers would be able only to access the websites and view the content that was there without the possibility of some kind of interaction. Content was served from the Server’s file-system.

  2. What is a smart contract?
    A smart contract is a piece of code that defines a specific action/s which can be set to execute when certain conditions are met. Smart contract are executable code on a blockchain network. Another important ingenuity and beauty of a Smart Contract is that it can store value/currency. Thus with the properties of a Smart Contract being lines of code, on a blockchain network, that can be triggered by specific conditions and can also store value and do different actions with it, we come to realization that Smart Contracts are/enable Programmable Money.

  3. How is transparency achieved with ethereum code?
    People can see the transactions and what they’re doing as they are part of the open Ethereum blockchain. Also, (I would assume) parties involved in the usage of a Smart Contract (or a set of them) usually have access to the code itself and can review what exactly a smart contract is doing.

  1. What was Web 1.0?
    Web 1.0 is the first stage of the internet or World Wide Web. Hosted Web sites can only contain static string and images as their contents. There are only content creators and content viewers. There’s no features like chat, accounts, and interactiveness.

  2. What is a smart contract?
    A smart contract is a programmed condition that only executes once a condition is achieved.

  3. How is transparency achieved with ethereum code?
    Ethereum is blockchain 2.0. Every transaction can be validated and reviewed in the blockchain.
