Aptos' BFT consensus mechanism as a response to the Blockchain trilemma
Aptos is based on a consensus mechanism based on Byzantine faults tolerance (Byzantine Fault Tolerance - BFT) , more precisely DiembftV4 , designed to optimize security, decentralization and scalability. Proof of Stake (POS) models , which are content to select validators according to their tokens, the BFT goes further by integrating an additional safety layer. It guarantees that the network can continue to operate even if part of the validators is malicious or faulty. This model solves the Blockchain trilemma - safety, scalability and decentralization - in a more balanced way, but with certain peculiarities at each level.
Safety: Robustness against malicious attacks
The Byzantine Mechanism Fault Tolerance (BFT) used by Aptos allows the network to operate even in the presence of malicious or failing validators. In a BFT system, the key rule is that, to guarantee the safety and integrity of the network, at least two thirds of the validators must be honest. This means that if 33 % or less validators try to manipulate or falsify transactions, they will not be able to take control of the consensus.
Concretely, each decision concerning the validation of a transaction block must obtain a consensus from the validators. If more than a third of the validators are malicious, they could block or delay validation, but will not be able to reach the majority necessary to distort the results. In other words, the network resists as long as the majority of validators (at least 67 %) act honestly . This model protects from attacks from attacks such as block falsification or transactions handling, because dishonest validators never have enough weight to reach a consensus on a corrupt chain.
Compared to the Proof of Stake (POS) , where the power of validators depends only on their tokens, the BFT of Aptos introduces this additional validators reliability requirement, guaranteeing increased robustness in the face of attacks.
Decentralization: a distribution of more controlled validators
The Proof of Stake of Aptos is based on a system where the validators are chosen according to the number of APT tokens that they have staked, but unlike conventional possees, the BFT consensus reinforces the governance and the impartiality of the network. However, this model raises the question of decentralization . As the weight of validators depends on the amount of Apt Staké, this can lead to a concentration of power in the hands of those who hold the most tokens. That said, Aptos reduces this risk by allowing any eligible participant to become a validator and by introducing rotation mechanisms to prevent a small group from controlling the network in a disproportionate manner.
Compared to a classic POS, where the stake of Tokens is the only criterion, the BFT of Aptos adds an additional safety layer thanks to its ability to maintain a consensus even in the presence of failing nodes.
Scalability: an optimized architecture
In terms of scalability , Aptos is capable of treating a significant number of transactions per second (TPS). Thanks to its modular architecture and its parallel execution mechanism, Aptos reaches a TPS in real time of 29.02 TX/S , which is more than twice as scalable as Ethereum with its 14.11 tx/s in real time. This places Aptos in a favorable position to deal with large volumes of transactions while maintaining network security. However, Aptos remains less scalable than Solana , which can reach 797 TX/s.
Rapid finality: a key advantage of Aptos
One of the aspects that distinguishes Aptos is his extremely fast time of purpose . The network guarantees that transactions are irreversible in 0.9 seconds , which clearly surpasses the purpose of Ethereum , which is 16 minutes . The purpose in the context of a blockchain refers to the moment when a transaction becomes immutable and can no longer be canceled. This allows Aptos users to be certain that their transactions are secured and validated in record time.
Recent innovations that allow Aptos to stand out
Aptos is distinguished by several technical innovations that strengthen its performance and safety. Among them:
- MOVE , the programming language designed to improve the safety of intelligent contracts.
- The parallel execution of transactions which optimizes treatment.
- The modular architecture which allows continuous updates without interruptions.
- The pipeline treatment which breaks down each step of the transaction process for maximum efficiency.
- Sharding that allows horizontal scaling .
These characteristics make Aptos a cutting -edge blockchain of technology, capable of treating a large volume of transactions without compromising security.
Move: a secure language for robust smart contract
Move language is at the heart of the Aptos ecosystem. This language, initially developed for the Diem blockchain, allows you to create intelligent contracts while guaranteeing maximum security. MOVE verifies that each operation is secure thanks to its move prover , a formal verification system which ensures that the safety rules are respected before a transaction is validated. For example, MOVE avoids problems of double expenditure or unauthorized creation of resources, by ensuring that each resource is unique and can only be manipulated with the right authorizations.
Parallel execution of transactions: optimized performance
Unlike traditional blockchains that treat transactions in a sequential way, Aptos allows parallel execution of transactions thanks to its block-Stm . This means that several transactions can be treated at the same time, which considerably increases the treatment speed.
In this system, different types of conflicts can occur between transactions, as when they try to modify the same data. Block-Stm detects these reading-writing conflicts and resolves them by applying a "re-roll" mechanism which optimizes the transactions concerned optimally, thus guaranteeing effective execution without sacrificing the consistency of the network.
The modular architecture of Aptos: flexibility and scalability
One of the great forces of Aptos lies in its modular architecture , which makes it possible to separate each component from the system to facilitate updates. This modularity allows you to add or modify features without affecting other parts of the network. For example, the protocol updates can be carried out without interruption of the service, which is a major advance compared to traditional blockchains where updates often require forks (separations from a two chain, often to introduce significant changes).
Examples of modular Aptos components: the consensus engine, the processing of transactions, and the tools for managing intelligent contracts. This approach makes it possible to adapt each component independently according to the needs of the network.
The pipeline treatment system: a revolution in the treatment of transactions
The Aptos transactional pipeline These steps include:
- Diffusion of transactions : transactions are first disseminated to all validators on the network.
- Classification of block metadata : transactions are grouped into blocks and classified in order of priority.
- Parallel execution of transactions : Each block is executed in parallel, thanks to the block-stm engine.
- Lot storage : validated transactions are stored in lots to reduce storage costs.
- Register certification : Once executed, transactions are certified and added irreversibly to the blockchain.
This process maximizes parallelism and increases the speed of processing of transactions while minimizing costs.
Sharding on Aptos: effective horizontal scaling
The homogeneous internal sharding of Aptos makes it possible to divide the blockchain into several sub-chains (or shards), all identical in their operation, in order to distribute the workload and to increase the capacity of the network. This allows Aptos to manage more transactions simultaneously, while maintaining the consistency of all data.
Unlike blockchains like Toncoin or Near Protocol , Aptos adopts a simpler approach where all shards work identically, thus reducing complexity for node operators.
Programmable resources: optimized management of assets
The MOVE language introduces the concept of programmable resources , which are digital assets governed by specific rules integrated into the intelligent contract. These resources cannot be copied or destroyed without explicit authorization, which guarantees the safety and integrity of transactions. For example, an NFT on Aptos could be programmed to be able to be transferred only under certain conditions defined by the contract.
Although Move is an innovation from Aptos, the concept of programmable resources is not exclusive to this blockchain. Other blockchains, such as Solana or Polkadot , also implement similar concepts, although the formal verification provided by Move is unique.
Advanced management of private keys to Aptos
Aptos offers an innovative approach to private keys management , in particular thanks to the possibility of delegating the management of keys to third parties in a secure manner . These trusted third parties may include companies specializing in the management of digital assets or community services, thus offering an additional safety layer to avoid the loss of private keys.
These entities are generally subject to rigorous safety audits to ensure that they act in a transparent and secure manner. Aptos also allows social recovery models, where several trusted people must approve an action to recover a key.

- TPS in real time : 29.02 transactions per second.
- TPS maximum recorded : 10,734 transactions per second.
- Maximum theoretical time : 160,000 transactions per second.
- Block time : 0.21 seconds.
- TRANSAGEMENTS : 0.9 seconds.
Compared to Ethereum (14.11 tx/s) and Avalanche (1.74 tx/s), Aptos offers much higher performance, even if it does not yet outdo Solana in terms of real -time scalability.
The Apt token: Utility and governance
In addition to its traditional role in paying transaction costs, Apt plays a key role in the governance of the protocol. APT holders can vote on proposals concerning the evolution of the network, thus guaranteeing that the protocol remains decentralized and focused on the community.
Aptos TVL : strong growth adoption
The rapid adoption of Aptos is clearly visible through the spectacular increase in its total Value Locked ( TVL ) , a key indicator that measures the total value of the assets locked in the Blockchain DEFI protocols. Between October 2023 and October 2024, TVL increased from 8 million Apt to 70 million APTs , testifying to a real craze for the protocol. In terms of dollars, this represents an impressive increase, going from $ 45 million in October 2023 to $ 730 million in October 2024.
This significant increase in TVL not only demonstrates the growing confidence of users in the protocols built on Aptos, but also the accelerated adoption of its technology. This dynamic place Aptos as an increasingly competitive actor in the blockchains universe, attracting investors, developers, and end users.
Tokenomics of Aptos
Aptos' jacket calendar follows a linear outbreak of 11.31 million APT released every 12 of the month, or around 1.01 % of the total supply of 1.12 billion APT.
In October 2024, 401.43 million Apt ( 35.81 % of the supply ) were released. So a relaxation of 11.31 million Apt corresponds to an inflation of around 2.8 % each month, which is high and implies a substantial selling pressure.
Strategic partnerships: a major growth potential
Aptos has also established strategic partnerships with several large companies like Google Cloud, which opens the way to potential integrations in key sectors. However, these partnerships can arouse concerns about centralization, although the role of the APT token in governance limits this influence.
Conclusion: Aptos, a promising blockchain for the future of the web3
Aptos positions himself as an extremely promising blockchain, capable of responding to the current challenges of decentralization, security and scalability. Thanks to its technical innovations and its in full development ecosystem, Aptos could well play a central role in the massive adoption of web3 .
