Well in the last thread of "WTF is" about ETHEREUM we said it pioneered the concept of a blockchain smart contract platform.

But have you ever wondered what is this "SMART CONTRACTS" is and what it does?

Lets dive into this "WTF is SMART CONTRACTS?" thread and learn more

1/
In simple words Smart contracts are translations of an agreement, including terms and conditions into a computational code.

- The term "SMART CONTRACT" was coined by a well-known computer scientist, law scholar & cryptographer Nick Szabo( @NickSzabo4 ) in early 1990's.

2/
@NickSzabo4 - It is a piece of code that can be executed automatically in a deterministic way

- Usually stored and executed on the blockchain

- Smart contracts can store, send and receive crypto currency

- Even call other smart contracts

- Smart contracts once deployed are immutale

3/
@NickSzabo4 - In Ethereum smart contracts are written in @solidity_lang created specifically for this

- As of now Ethereum is the most famous general-purpose smart contract platform

- There are many other platforms like Cardano, Tezos, Solana, EOS etc., with different charecteristics

4/
@NickSzabo4 @solidity_lang Usecases of Smart Contracts:

- Banking & Financial Services - DeFi Dapps
- Digital Identity
- Organizations - DAO's
- Tokenization(Including NFT's)
- Initial Coin Offerings - ICO
- Legal Applications
- Games
- Crowdfunding

5/
@NickSzabo4 @solidity_lang Few Risks:

- Common to every other software "BUGS"
* The DAOHACK which resulted in exploiting 3.6 million Ether
* Parity’s Multi-signature Wallet Hack worth 150,000 Ether
* Parity User-Triggered Wallet Freeze "freezing more than 513,774 ETH"

- Regulations & Tax

6/
@NickSzabo4 @solidity_lang As there are both positives and negatives for every product, here it is for smart contracts:

* But majority of problems are solvable over time.

7/
@NickSzabo4 @solidity_lang If you are a developer take advantage of the technology, be part of the revolution and develop something which will change the way we use it now.

If you are a normal person, be ready to expereince the ride which is going to change everything the way we use in near future.

8/
@NickSzabo4 @solidity_lang That brings an end to the pretty short thread on Smart Contracts. I hope it is clear and useful.

Day-5(#R2D5)

Focusing on JavaScript alone can change your life.

JavaScript lets you become a:

✅ Frontend Developer
✅ Backend Developer
✅ Blockchain/Web3 Developer
✅ Game Developer
✅ Embedded Systems Engineer
✅ Mobile App Developer

Yes, our main topic today is

"JAVASCRIPT"

This thread is part of the WEB3 developer roadmap.

#100DaysOfWeb3 #100DaysOfCode #web3 #developer #21DaysOfLearnandShare
As I told you already JS alone can change your life so I cannot restrict how many days you want to spend JS as part of the roadmap.

But If you decide to have strong building blocks in JS check:-

Day-4(#R2D4)

Today's here are the resources about:-
HTTP Caching, RPC Protocol, Browser’s developer tools

As part of the WEB3 developer roadmap.

🧵👇

1/
Caching :

As yesterday mentioned our browser tries to check the local cache first to resolve DNS.

Similarly, there are CDN services that provide complete websites from their cache using the HTTP protocol.

cloudflare.com/en-in/learning…

2/
RPC Protocol :

Normally our programs and processes run locally in our system, but there are some protocols that support execution in a remote system. Such as RPC protocol, which makes it easy for the peer-to-peer networks.

Well, today let us see some more very basic yet important that we use daily and don't notice what happens in the background.

How does a WEB BROWSER work?
What is DNS, HTTP protocol?

You can start directly from 9/ tweet if you don't need basic introduction stuff.

Companies typically make free web-browsers with some financial interest in how you use their product.

With this, they are able to track your computing habits and make revenue by selling your data to third-party vendors

2/
Okay, what exactly is a web browser?

In short, it is the place where you interact with the web.

Remember: The words internet and web are not interchangeable, They are related but two different things

Networking is the word we use when we talk about connecting computers together so that they can share data with each other.

Local networks range from simple networks consisting of two computers to networks connecting hundreds of thousands of devices

2/
Who owns the internet?
internet is not owned by any individual or group.

The internet is a worldwide collection of interconnected networks (network of networks), cooperating with each other to exchange information using common standards

Well here i am, to help you understand the basic details of it in simple terms

So, Lets dive in "WTF is DeFi?"

👇🧵

1/
- In the previous "WTF is" thread about ETHEREUM part 1 i told that ethereum was created with the intention to decentralize everything.

- Smart Contracts help acheive decentralization of majority of things on blockchain.

Check this 👉bit.ly/WTFisSMARTCONT…

2/
- Financial system is one main thing that runs by centralized entities like governments and intermediaries like banks

- DeFi relies heavily on - Cryptography, Blockchain & Smart Contracts

- According to @defipulse today in DeFi Total Value Locked(TVL) is $92.36B 😱
