Aptos (APT) Crypto: The Next-Gen Blockchain Built for Speed and Security

Aptos is a Layer 1 blockchain designed to be fast, secure, and scalable, launched in 2022, with its mainnet called “Aptos Autumn”.

Aptos is a Layer 1 blockchain designed for speed, security, and scalability. It aims to improve transaction efficiency while ensuring strong protection against fraud. The blockchain uses a unique Move programming language and offers a high transaction throughput of 160,000 tps and low fees.

This guide will explain what Aptos is, how it works, use cases of APT tokens, and how to buy and store APT tokens.

What is Aptos?

Aptos is a new Layer 1 blockchain that was launched in 2022, with its mainnet called "Aptos Autumn". The blockchain is capable of processing over 160,000 transactions per second (TPS), compared to Bitcoin's 7 TPS or Ethereum's 15-40 TPS.

Aptos uses a combination of Proof-of-Stake (PoS) and a special consensus method called AptosBFT. It also has a modular design, allowing for easy updates without shutting down.

What is Aptos Labs?

Aptos Labs is the company that developed the Aptos blockchain. It was founded in 2021 by Mo Shaikh and Avery Ching, both of whom previously worked on the Diem blockchain project at Meta.

After Meta abandoned Diem in January 2022, the technology and ideas were used to create Aptos. The company has raised significant funding, including a $200 million Series C round led by Andreessen Horowitz (a16z) in March 2022, a $150 million Series B funding in July 2022 co-led by FTX Ventures and Jump Crypto, and additional funds from Binance Labs in September 2022, pushing its valuation to $4 billion.

How Does Aptos Work?

Move Programming Language

The Move Programming Language is a key component of Aptos, originally created for Meta's Diem project. It is a Rust-based language designed to make writing smart contracts safer and simpler.

Move ensures that resources, such as digital coins, can't be copied or lost through programming errors, and they can only be moved between accounts. This minimizes the potential for hacking and bugs. The language also includes a smart contract verifier called the Move Prover, which can check for common programming mistakes.

Block-STM Technology

Block-STM Technology is the engine that powers Aptos's ability to process over 160,000 TPS, as demonstrated by Aptos Labs in their testing. STM stands for Software Transactional Memory.

This system runs transactions optimistically in parallel, meaning it processes many transactions at once without waiting and checks them afterward for any errors. If a transaction fails, it gets re-run using smart memory tools to resolve conflicts. This method utilizes all available computing power efficiently, making Aptos significantly faster than blockchains that process transactions one by one.

Data Model

The Data Model in Aptos organizes information effectively for smooth operation of the blockchain. It allocates a unique identifier starting from 0 for each account, and new accounts are created with increasing identifiers as transactions occur.

Data is stored in a format that validators can access quickly, and resources are intrinsically tied to specific accounts, ensuring clarity and security in resource management.

Byzantine Fault Tolerance (BFT) Consensus Protocol

The Byzantine Fault Tolerance (BFT) Consensus Mechanism, specifically AptosBFT version 4, guarantees that Aptos remains secure even if some validators fail or act dishonestly.

This system can handle up to one-third of validators being faulty, which equates to 33% of the network's total voting power, without compromising the blockchain's integrity.

Parallel Transaction Execution Engine

The Parallel Transaction Execution Engine is what enables Aptos to achieve extremely high throughput, processing thousands of transactions simultaneously rather than one after another.

It runs transactions in batches, validates them later, and resolves any issues by re-running failed transactions. This approach minimizes waiting times and boosts transaction throughput, with a future goal of 1 million TPS.

Aptos Ecosystem

The Aptos ecosystem is a growing network of projects built on the Aptos blockchain. Currently, there are 194 total projects built or integrated on the Aptos blockchain. Some of the top Aptos ecosystem eprojects are:

The Aptos Crypto Token (APT)

The Aptos crypto token (APT) is the native cryptocurrency of the Aptos network. It powers the network by handling fees, staking, and governance.

Currently, APT token ranks among the top #30 cryptocurrencies with a market cap of $3.59B, according to CMC data.

APT Tokenomics

APT tokenomics define how the token is distributed, unlocked, and used over time. The initial total supply of APT was 1 billion tokens at the mainnet launch. The token uses 8 decimal places, with the smallest unit called
