# History of Aptos

Hey there, fellow developers! We're super excited to have you here with us on this course.

![so-excited.gif](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/History-of-aptos/so-excited.gif?raw=true)

Now, imagine we asked you to list the top three things you look for in a "Good" blockchain project. You might mention the number of pages in the white paper, how active the founders are on Twitter, or when they're planning their next airdrop or mainnet launch. 

![checklist.gif](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/History-of-aptos/checklist.gif?raw=true)

We get it—these factors are important!
But there's one element that's often overlooked: a cool origin story.
 
![orgin-story.png](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/History-of-aptos/orgin-story.png?raw=true)

A solid origin story can tell you so much about a project. It reveals the vision behind the initiative, the problems it aims to solve, the people involved, and their motivations for driving the project forward.

So, as we embark on this epic quest to learn and master the Aptos blockchain, we think it would be fantastic to start with the story of Aptos and how it evolved into one of the most prominent blockchain protocols in the space. 

![aptos-logo.png](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/History-of-aptos/aptos-logo.png?raw=true)

So, Let's just dive right in and discover not just the 'what' and the 'how,' but also the 'why' behind Aptos!

## A Facebook Project

So, not so long ago, in 2019, Meta, formerly Facebook, officially announced that They were planning to launch a blockchain-based global payment system called Libra, with its own stablecoin. 

![libra-launch.png](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/History-of-aptos/libra-launch.png?raw=true)
The idea was to make sending money across borders as cheap and easy as possible. You can imagine the buzz—it had people both super excited and pretty skeptical.

But the scepticism wasn't just from everyday folks; governments and regulators were on high alert, too. They started raising concerns right away. Could this huge project disrupt national currencies? What about the risks of money laundering? These concerns quickly turned into a massive storm of opposition for the project.

![libra-regulator.png](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/History-of-aptos/libra-regulator.png?raw=true)

In an effort to calm things down, Facebook made some significant changes. They rebranded Libra as Diem, shifted their focus to single-currency stablecoins, and overhauled the project’s governance. But, even with these changes, the headwinds continued. Key partners started to back out, and Facebook, feeling the heat, began to waver.

By January 2022, it was basically over. The Diem Association sold its assets, officially putting an end to the project. But our story actually doesn't end there.

![diem-shut-down.png](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/History-of-aptos/diem-shut-down.png?raw=true)

## A Bold Move

You see, many of the engineers and developers who spent years on the Diem project weren't about to just give up on the whole thing. Key among them were Mo Shaikh and Avery Ching, who played pivotal roles in the development of the Diem project, particularly it's crypto wallet tagged Novi Wallet. 

![founders.png](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/History-of-aptos/founders.png?raw=true)

They recognized the potential of the technology they'd created, especially the Move programming language. Move, inspired by the Rust language, was created specifically for blockchain development and prioritized security and data verification to minimize potential errors and vulnerabilities.

![move-logo.jpg](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/History-of-aptos/move-logo.jpg?raw=true)

Move's focus on safety wasn't just theoretical. It was born from real-world experience building Diem, where security flaws could have dire consequences in a financial context. Additionally, Move's design aimed to make it easier for developers to formally verify their smart contracts, adding another layer of protection and reliability to the applications built upon it.

Motivated by a desire to see their hard work realized, Shaikh, Ching, and others from the original Diem team founded Aptos Labs. This wasn't another rebranding exercise. It signified a focused evolution, building upon the core strengths of Diem while addressing the regulatory concerns and challenges that ultimately hampered its success.

The Aptos mainnet officially launched on October 17, 2022.
  
![launch-tweet.png](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/History-of-aptos/launch-tweet.png?raw=true)

The core motivations behind building the protocol can be distilled into these key points:

- **Scalability:** Aptos aims to handle significantly more transactions per second than older blockchains, positioning itself as a solution for large-scale adoption.
- **Developer Experience:** With Move and a focus on tooling, Aptos wants to make building decentralized applications a seamless and secure process.
- **User Focus:** Recognizing that usability is key to mainstream blockchain usage, Aptos is prioritizing intuitive user interfaces and simplifying the complexities of the technology.

## Funding the vision

Now, with great ideas comes greater funding. And if those ideas are carried by an experienced team, you might just raise a few hundred million dollars – even *before* launching your major product. Such was the case with Aptos. Even before their mainnet launch, Aptos Labs raised a massive $200 million in March 2022, followed by another $150 million in July of the same year. Investors like Andreessen Horowitz (a16z), FTX Ventures, and Coinbase Ventures backed Aptos early on. This kind of funding demonstrates the confidence investors had in the project and its potential to make a real impact in the blockchain space.

## Wrap up

So, there you go folks... a comprehensive walk through the history of Aptos. From its roots in the Diem project to its reimagined vision, the Aptos story is one of resilience, innovation, and the relentless pursuit of a better blockchain. But this is just the beginning! In the coming sections, we'll take an even deeper dive into the world of Aptos, exploring its technology and empowering you to build amazing things on this exciting platform.

History of Aptos

# What is Aptos?

Welcome back, my friend! Since you've chosen to dive into this course, you probably already know how quickly blockchain technology has skyrocketed. But have you ever stopped to think why it’s grown so fast, especially compared to other tech like the internet which took ages to catch on? It's pretty intriguing, right?

![blockchain-v-internet.png](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/What-is-aptos/blockchain-v-internet.png?raw=true)

The magic of blockchain starts with some key features you've probably heard about while Googling around: decentralization and transparency. Impressive as these features are, they alone aren't enough to thrust blockchain into the mainstream. Why? Well, blockchains are notoriously slow and costly. 

![blockchain-speed-meme.jpg](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/What-is-aptos/blockchain-speed-meme.jpg?raw=true)

In an era where we might ditch a website just because it loads slowly, speed and cost become big barriers when it comes to adopting new tech.

What's the best fix for this? A blockchain that's quicker, cheaper, and can scale up. And that brings us to why we're here—yes, the Aptos blockchain. You might be wondering what makes Aptos stand out. Well, Let’s Just jump right in and explore the key features that make the Aptos blockchain so unique and why it's catching the attention of developers everywhere.

## Key Features of Aptos

Here are some key features which make Aptos blockchain stand out among the crowd of blockchains that exist in web3:

**Move Language Integration**

![move-language-integration-icon.png](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/What-is-aptos/move-language-integration-icon.png?raw=true)

Aptos uses the Move language for rapid and secure transaction execution. It ensures protection against malicious activities and increases overall security as well.

**High Throughput & Low Latency**

![high-tp.png](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/What-is-aptos/high-tp.png?raw=true)

 Aptos achieves a high throughput as it utilizes a pipelined transaction processing approach. What this means is that, it breaks down the transaction execution process into multiple stages that can be executed in parallel. Although each stage of the transaction process operates independently, they passing data or results from one stage to another. 

**Atomic Transaction Support** 

![atomic-icon.png](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/What-is-aptos/atomic-icon.png?raw=true)
As we mentioned, the transactions in Aptos are broken down into multiple stages. Now atomic transaction support ensures that even if any one of these transactions that are broken down into stages fails, the entire transaction fails and that there is no state change in the blockchain. 

**Modular Architecture & Upgradability**

![modular-icon.png](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/What-is-aptos/modular-icon.png?raw=true)
Aptos is a modular blockchain, meaning it is made up of independent parts or modules. Now unlike other blockchains where the whole system suffers during and upgrade, in Aptos, you can update specific modules or components which makes the upgrade process much more faster and more efficient.

**Scalability Initiatives**

![scailabity-icon.png](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/What-is-aptos/scailabity-icon.png?raw=true)
Aptos is working on ways to handle more transactions and grow its capacity without making things more complicated for the nodes that operate the network by using techniques like internal and state sharding wherein, instead of relying solely on individual validators (nodes) to handle all transactions, Aptos divides the workload among multiple validators or shards.

**Flexible Data Model** 

![flex-icon.png](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/What-is-aptos/flex-icon.png?raw=true)

Aptos allows you to manage your keys in flexible ways. This means users have options to choose how they want to store and use their keys, whether through software wallets, hardware wallets, or other methods. It also provides users with choices when it comes to custody of their assets. Users can opt for self-custody, where they manage their keys independently, or choose custodial services provided by trusted third parties such as exchanges or wallet providers.

## That’s a wrap

We hope this gives you a good snapshot of what Aptos is all about and the standout features it brings to the table. Next up, we’ll explore some of the popular Dapps that have been built on Aptos. Stay tuned to see how developers are leveraging Aptos to create cool applications!

# How Does Aptos Even Work? (Part-I) 

Hey! Back for another round of Aptos knowledge?

Okay let’s do a quick recap, we've covered what Aptos is and what it's all about, but you might be wondering: **how does this whole thing actually work?**

This is where things get interesting. As developers, we naturally love diving into the nitty-gritty of how something is built.  ️In this lesson, we're going to take a deep dive into the core workings of the Aptos blockchain.

Okay now buckle up! This lesson is going to be a bit detailed but hold tight as I will walk you through every detailed with examples you can relate.

## Overview of Aptos core working principles

Hey there! We've been exploring Aptos, but you might be curious: what makes this town tick?

![giphy (2).gif](https://github.com/0xmetaschool/Learning-Projects/blob/main/Aptos%20C1%20Introduction%20to%20Aptos/2.%20Understanding%20Aptos%20Architecture/How%20Does%20Aptos%20Even%20Work%20(Part-I)%20Assets/giphy_(2).gif?raw=true)

Imagine Aptos like a busy marketplace with a constant flow of goods. Transactions are like these goods, carefully packed in boxes (blocks) before entering the town. Validators act as the security guards, checking each box thoroughly before it gets delivered.

Now, with multiple guards, how do we know they're all honest? Well, Aptos, like any good town, has a set of rules everyone follows (consensus mechanism). In Aptos, this rulebook is called Proof-of-Stake (PoS). Think of it as a system where guards with a higher stake in the town's safety (holding more digital currency) have a greater say in validating transactions.

Every busy town needs a record keeper, right? In Aptos, these are the librarians – the full nodes. They meticulously record every transaction (data on the blockchain) since the town's founding. You can access all this information through them, just like a giant history book! But what if you only need the latest news, not the whole story? That's where light clients come in. These are like librarians who let you access just the most recent box (block) of information.

Now, imagine these merchants in the marketplace aren't just selling goods, but also offering services. These services are like smart contracts – self-executing agreements that follow a specific set of rules.

But how do we ensure these services are reliable and secure? Here's where Move language comes in. It's like a super clear instruction manual for merchants, written in a language everyone can understand. This manual helps them create secure and dependable smart contracts, so the chances of merchants making errors are low since they already have a clear instruction manual.

![giphy (3).gif](https://github.com/0xmetaschool/Learning-Projects/blob/main/Aptos%20C1%20Introduction%20to%20Aptos/2.%20Understanding%20Aptos%20Architecture/How%20Does%20Aptos%20Even%20Work%20(Part-I)%20Assets/giphy_(3).gif?raw=true)

But what if there's a sudden surge of customers, and merchants struggle to handle all the requests at once? Aptos has a clever trick up its sleeve called Block-STM. This word might sound too technical but Imagine it like a system that lets merchants group similar orders together and process them efficiently, even during peak shopping hours. This keeps the marketplace running smoothly, even with complex transactions. 

This might seem like a lot to take in , But don’t worry we will be going through them step by step and explain everything in detail. 

## Why Move Over Solidity?

Imagine our bustling marketplace again, but this time, we have two types of instruction manuals for our merchants: Solidity and Move.

![1703100156129.gif](https://github.com/0xmetaschool/Learning-Projects/blob/main/Aptos%20C1%20Introduction%20to%20Aptos/2.%20Understanding%20Aptos%20Architecture/How%20Does%20Aptos%20Even%20Work%20(Part-I)%20Assets/1703100156129.gif?raw=true)

Solidity is like an older, more complex manual. It gets the job done, but it's easy for merchants to make mistakes or misinterpret the instructions. This can lead to security issues, like a merchant (Smart contracts) accidentally leaving their store unlocked overnight (Security flaws caused due to logical errors).

On the other hand, Move is like a well-organized manual that's designed with safety and clarity in mind. It's like having a step-by-step guide with pictures and diagrams, making it much easier for merchants (Smart Contracts) to follow along and avoid mistakes. In Move, it’s built in to protect against common smart contract vulnerabilities such as reentrancy attacks (YOU really have to google it!! People lost millions due to this one flaw in Solidity)

One of Move's superpowers is its resource-oriented design.

Think of these resources as secure vaults within your shop. These vaults are special because they follow a strict set of rules:

- **Unique and Valuable:** Just like precious items in your shop, resources represent something of value in the marketplace (Smart contract).
- **Can't Be Duplicated:** Imagine having a magic machine that can't copy your most valuable items. Well you don’t need one for “Resources” as they can't be copied or counterfeited, ensuring their authenticity.
- **Only One Location:** Each valuable item in your shop has its own designated space in the vault, right? Likewise, resources can only exist in one place at a time, preventing confusion about ownership.

Well there are a lot of things to talk about move and why this is going to be the next big smart contract language, but for now this is it, we will talk more about it in the next course, maybe deploy some smart contract in move, who knows …. 😉

How Does Aptos Even Work? (Part-I)

# How Does Aptos Even Work? (Part-II) 

Welcome back, folks!! In the last lesson we learned how Aptos works in a brief and also dug deep into the why you should be learning move over solidity. Well in this lesson, let’s dig deep further into how Aptos works and what makes it faster than other blockchains.

Okay, let me reveal the secret sauce: it’s **Parallel Execution**!!

## Aptos parallel execution model

![e8d9681230406ed1c64e8066f8fe7f81.gif](https://github.com/0xmetaschool/Learning-Projects/blob/main/Aptos%20C1%20Introduction%20to%20Aptos/2.%20Understanding%20Aptos%20Architecture/How%20Does%20Aptos%20Even%20Work%20(Part-II)%20Assets/e8d9681230406ed1c64e8066f8fe7f81.gif?raw=true)

Imagine having multiple checkout lanes open at once, but with a twist! Transactions are still grouped into batches, like carts full of goods. However, with parallel processing, it's like cashiers (validators) can grab individual items (transactions) from different carts and scan them simultaneously, as long as they're not the same item (data). This significantly speeds things up, making Aptos perfect for shops(dApps) that need speedy transactions!

**But wait, how does it avoid chaos?** Here's where our super-smart coordinator, **Block-STM**, comes in. It keeps everything organized and prevents mix-ups, even when multiple customers (transactions) try to buy the same item (data).

**Let's see how this works with two different scenarios:**

![8op4.gif](https://github.com/0xmetaschool/Learning-Projects/blob/main/Aptos%20C1%20Introduction%20to%20Aptos/2.%20Understanding%20Aptos%20Architecture/How%20Does%20Aptos%20Even%20Work%20(Part-II)%20Assets/8op4.gif?raw=true)

For the first scenario, imagine two customers, Alice and Bob, want to buy separate items from the same shop (transactions in the same batch). With parallel processing, cashiers (validators) can scan their items (transactions) simultaneously because they're not trying to buy the same thing (data). This is super efficient!

Now, imagine Alice wants to buy a hat, and then Bob wants to buy the same hat after her (conflicting transactions). Block-STM, our super-smart coordinator, comes into play here. It might let Bob scan the hat first (speculative execution), but then realize there's a conflict with Alice's purchase (earlier transaction). In this case, Bob's transaction would be put on hold and re-attempted later, ensuring only one person gets the hat.

**Here's the breakdown:**

1. **Batching & Sharing:** Transactions are grouped into batches, like carts, then shared with everyone in the marketplace (validators) to keep everyone informed.
2. **Parallel Processing Power:** Block-STM lets these transactions be processed at the same time, even if they involve different items (data) from the same cart (batch). It tracks everything and only lets one purchase (transaction) go through if there's a conflict with the same item.
3. **Double-Checking & Storing:** Once everything's processed, Block-STM makes sure everything is legit, then the changes (like updated shop inventory) are stored permanently.

I hope now you have gained a good amount of knowledge on how Aptos works! Well in the coming lessons you will be learning a lot more about Aptos and why you should build on it. 

## Wrap up

By leveraging parallel execution, Aptos can process thousands of transactions per second, making it one of the fastest and most scalable blockchain platforms out there. It's like having a bustling marketplace that can handle a massive influx of customers without breaking a sweat!

# Advantages of building on Aptos

Alright, by now we've covered pretty much everything there is to know about Aptos and its inner workings. Now comes the big question: What's in it for you as developers? What are the benefits, the advantages, the bonuses that come with building cool applications on Aptos?

![Screen Recording 2024-04-25 at 10.37.52 AM.gif](https://github.com/0xmetaschool/Learning-Projects/blob/main/assests_for_all/C1%20Introduction%20to%20Aptos/Advantages%20of%20building%20on%20Aptos/Screen_Recording_2024-04-25_at_10.37.52_AM.gif?raw=true)

# Reasons for Building on Aptos

### Aptos Handles A Lot of Transactions Quickly
![fast-cashier.gif](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/Advantages-of-building-on-Aptos/fast-cashier.gif?raw=true)

Aptos is known for being a very fast blockchain, capable of handling numerous transactions at the same time. This is possible because of a technique called parallel execution, where Aptos processes many transactions simultaneously, but only if they don't conflict with each other. This method is much faster than processing transactions one after another.

Additionally, Aptos uses something called modularity, which means it breaks the transaction process into smaller, independent parts. This setup allows certain parts of the transaction process, like validation (where transactions are checked and confirmed), to be more flexible and efficient. Validators can focus on high-fee transactions first, making the whole system more streamlined.

### Aptos Keeps Everything Secure with Move
![security.gif](https://github.com/0xmetaschool/Learning-Projects/blob/0181077452c784230a795175fb6e8076b6950231/assests_for_all/C1%20Introduction%20to%20Aptos/Advantages-of-building-on-Aptos/security.gif?raw=true)
Aptos uses a programming language called Move, and it’s a bit like the superhero of coding languages when it comes to safety and security. Move comes packed with features that help it automatically spot any sneaky or harmful smart contracts trying to stir up trouble.

Another cool tool in Move’s belt is something called formal verification. This is basically using some serious math to double-check that everything a program is supposed to do is spot on, without any errors.

So, by using Move, Aptos is really focusing on keeping things secure. It’s like having a really good security system in place to make sure everything runs smoothly and safely.

### Aptos Allows easy Upgradability and on-chain governance
