About
What Is Aptos?
Aptos is a Layer 1 Proof-of-Stake (PoS) blockchain that employs a novel smart contract programming language called Move, a Rust-based programming language that was independently developed by Meta (formerly Facebook)’s Diem blockchain engineers.
Aptos’s vision is a blockchain that brings mainstream adoption to web3 and empowers an ecosystem of DApps to solve real-world user problems.
The PoS blockchain can achieve a theoretical transaction throughput of over 150,000 transactions per second (tps) through parallel execution.
In March 2022, Aptos raised $200 million in a seed round led by the venture capital firm Andreessen Horowitz (a16z). Other crypto heavyweights like Tiger Global and Multicoin Capital took part in the funding round. Fast forward to July, the startup raised another $200 million in a Series A round with participation from Dragonfly, Apollo Global, Franklin Templeton, Animoca, Jump Crypto and others.
Two months later, Binance Labs made a strategic investment of an undisclosed amount in Aptos.
On Oct. 18, 2022, Aptos announced the mainnet launch, while the Aptos genesis occurred on Oct. 12, 2022.
Who Are the Founders of Aptos?
Aptos is the brainchild of Mo Shaikh and Avery Ching, both former employees of Meta. Mo, who is the current CEO of the company, is a founder with years of multinational financial services and blockchain/crypto experience. According to his LinkedIn profile, he specializes in scaling products and has experience in the private equity and venture capital markets.
Ching, on the other hand, is the CTO of Aptos. He is a software engineer and was one of the principal software engineers at Meta.
The duo worked together on the Diem blockchain project at Meta. Shaikh and Ching decided to join forces to create Aptos Labs when the Diem project was discontinued in January 2022. It, therefore, comes as no surprise that Aptos employs some of the technicalities of Diem.
Other members of the Aptos team include researchers, designers, and engineers from Diem.
What Makes Aptos Unique?
For a start, the Aptos team claims that its network can process over 150,000 tps. By comparison, Ethereum’s mainnet tps is around 12 to 15.
This high transaction throughput is possible through a parallel execution engine (Block-STM) — a byzantine fault-tolerant (BFT) PoS consensus mechanism. For context, most blockchains execute transactions sequentially, which means that a single failed transaction or high demand on the network could hold up the entire chain.
In the case of Aptos, all transactions are processed simultaneously and validated afterward. Failed transactions are either re-executed or aborted, thanks to the blockchain’s software transactional memory libraries, which spot and manage conflicts.
Aptos is built using Move, a new smart contract programming language that claims to offer advantages to Solidity, the EVM-based programming language. This includes blockchain commands that can be easily verified, modification of private key and modular design of Aptos.
New use cases can be realized through Aptos’ upgradeability and configurability, while horizontal throughput scalability — through the natively-implemented sharding feature — provides a better user experience.
How Much Aptos is in Circulation?
APT is the native currency of the Aptos blockchain. It has an initial total supply of 1 billion and at the time of writing, its circulating supply is 130 million APT.
The distribution is as follows: Community (51.02%); Core Contributors (19.00%); Foundation (16.50%); Investors (13.48%).
Under the Community allocation, around 80% are held by the Aptos Foundation and the remaining by Aptos Labs. This will be used to support community growth and Aptos Foundation initiatives, and the remainder will be unlocked monthly over the next ten years.
Investors and core contributors are subjected to a four-year vesting schedule from mainnet launch. The Aptos team announced a token airdrop of 20 million APT tokens to early testnet users on Oct. 19, 2022.

What Is Aptos Bridge?
On-chain user application protocol called LayerZero Labs launched the Aptos Bridge on October 19, 2022.
The blockchain bridge will allow users to transfer ETH, USDC, and USDT from Ethereum, BNB Chain, Polygon, Avalanche, and Optimism to Aptos.
How Is the Aptos Network Secured?
Aptos uses two consensus protocols – Proof-of-Stake and AptosBFT.
AptosBFT is quite similar to DiemBFT, originally developed for Diem. “BFT '' means ‘Byzantine Fault-Tolerant,’ and a network is said to be Byzantine fault-tolerant if it can continue to operate normally even if some of its members go offline or turn malicious.
AptosBFT is a custom-made consensus algorithm based on the HotStuff protocol. While there are a lot of background technicalities around how the protocol secures the network, the algorithm analyzes the on-chain state and automatically updates leader rotations to adjust for non-responsive validators without human intervention.

What blockchain does Aptos use? Is it its own blockchain or built on top of another?
Aptos operates on its own independent blockchain, which was designed from the ground up to address scalability, security, and usability challenges in existing blockchain networks.
Key Points About Aptos' Blockchain:
Native Blockchain – Aptos is not built on top of another blockchain (like Ethereum or Solana). It is a standalone Layer 1 (L1) blockchain with its own consensus mechanism, smart contract platform, and tokenomics.
Consensus Mechanism – Aptos uses Move-based consensus, leveraging the Move programming language (originally developed for Diem, a Facebook-backed project). This includes a Proof-of-Stake (PoS) model with a unique AptosBFT consensus algorithm for high throughput and low latency.
Scalability & Performance – Aptos is designed for high throughput (targeting 100,000+ transactions per second) and low latency, aiming to compete with traditional payment systems.
Smart Contracts – Aptos uses Move, a secure, flexible, and expressive language for writing smart contracts, which was originally developed for Diem but has been significantly enhanced for Aptos.
Token & Ecosystem – The native token of the Aptos blockchain is APT, used for governance, staking, and transaction fees.
Comparison to Other Blockchains:
- Unlike Ethereum (which is a general-purpose L1) or Solana (another high-performance L1), Aptos is a new, independent blockchain with its own architecture.
- It was not forked from any existing chain but was built from scratch by former Meta (Facebook) engineers who worked on the Diem project.
Conclusion:
Aptos is its own blockchain, not a layer built on top of another. It competes directly with other L1 blockchains like Ethereum, Solana, and Cosmos in terms of scalability and performance.

How fast are Aptos transactions? What is the typical confirmation time and throughput (transactions per second)?
Aptos is designed to be a high-performance blockchain with fast transaction speeds and high throughput. Here are the key metrics for Aptos transactions:
1. Transaction Speed (Confirmation Time)
- Typical Confirmation Time: 0.5 to 1 second (on average, under normal network conditions).
- Finality: Aptos uses a Byzantine Fault Tolerant (BFT) consensus mechanism, meaning transactions are finalized quickly once confirmed.
2. Throughput (Transactions Per Second - TPS)
- Theoretical Maximum: 160,000 TPS (as claimed by Aptos, under optimal conditions).
- Real-World Performance: 50,000 to 100,000 TPS (observed in testnets and early mainnet activity).
- Comparison: This is significantly higher than Ethereum (~15-30 TPS) and Solana (~2,000-5,000 TPS).
3. Factors Affecting Performance
- Network Congestion: During high demand, confirmation times may increase slightly.
- Transaction Complexity: Simple transfers are faster than smart contract executions.
- Node Infrastructure: Aptos is optimized for high scalability, but real-world performance depends on validator participation.
4. Why Aptos is Fast
- Move Language: Aptos uses the Move programming language, which is designed for security and efficiency.
- Parallel Execution Engine (AptosBFT): Enables high throughput by processing transactions in parallel.
- Optimized Data Structures: Efficient storage and retrieval mechanisms reduce latency.
Conclusion
Aptos is one of the fastest blockchains, with sub-second confirmations and industry-leading throughput (50,000–160,000 TPS). However, real-world performance may vary based on network conditions.

How much data can I store on the Aptos blockchain? Does it support on-chain data storage?
The Aptos blockchain supports on-chain data storage, but there are important limitations and considerations to keep in mind:
1. On-Chain Data Storage in Aptos
Aptos allows developers to store data on-chain using Move smart contracts. This data is stored in the global state of the blockchain, which is replicated across all validators.
2. Storage Limits & Costs
No Hard Cap on Data Size: Unlike some blockchains (e.g., Ethereum with gas limits), Aptos does not have a strict per-transaction data limit. However, storing large amounts of data can be expensive due to:
- Storage Rent: Aptos charges a storage fee (paid in APT) to store data on-chain. This fee is designed to prevent spam and ensure efficient use of validator resources.
- Gas Costs: Writing data to the blockchain consumes gas, and large transactions may require higher gas fees.
Practical Limits:
- Transaction Size: While there’s no strict limit, extremely large transactions may be rejected by validators due to performance concerns.
- Validator Storage Constraints: Validators must store all on-chain data, so excessive storage could lead to network congestion or higher operational costs for validators.
3. Alternatives for Large Data Storage
For large-scale data storage, it’s more efficient to:
- Store only hashes or references on-chain (e.g., IPFS, Arweave, or centralized storage).
- Use off-chain solutions (e.g., databases, cloud storage) and interact with Aptos via smart contracts.
4. Example Use Cases for On-Chain Data
- User profiles (small metadata)
- Token metadata (NFT attributes)
- Game state (small-scale decentralized apps)
Conclusion
Aptos supports on-chain data storage, but it’s not designed for large-scale data storage due to cost and scalability constraints. For most applications, a hybrid approach (on-chain references + off-chain storage) is recommended.
