What is DEXON

DEXON is the latest distributed ledger technology that solves the blockchain trilemma: decentralization, security, and scalability.
It provides the ultimate solution for hosting industry-level DApps that can serve more than a billion users in real-world scenarios such as IoT, smart payments, gaming, music, and assets exchange services.
DEXON is capable of processing 10k+ TPS with transaction confirmation finality of 1 second. Moreover, the DEXON Consensus Algorithm is mathematically proven to be secure while being Byzantine fault tolerant.
DEXON is currently backed by global top-tier venture capital firms such as IDG Capital. As a strategic partner, IDG Capital has led the first round of $20 million USD investment in DEXON.

Technology

DEXON tackles the infamous “blockchain trilemma” of existing blockchain systems with cross-cutting, interdisciplinary elements from cryptography, applied mathematics, and computer science theories.

Decentralization

SecurityScalability

The Trilemma of Current Blockchain Technology

Problem: Decentralization

Our solution: Fair Cryptographic Sortition

All users with enough DXN can be validators and join the DEXON network. A small set of validators, called the notary set, is selected fairly to propose and verify the blocks every hour. All the validators have an equal probability of being chosen through cryptographic sortition. This mechanism allows DEXON to perform with high efficiency, while supporting thousands of validators joining the network, at the same time.

Problem: Security

Our solution: Partition-Resilient Byzantine Agreement

The security of DEXON is guaranteed by our “partition-resilient Byzantine agreement.” With our Byzantine agreement protocol, we are able to achieve the safety and liveness of the network. Even if the network gets disconnected (e.g., cable is broken or cloud services shut down), the safety of the consensus still holds and DEXON will keep operating normally once the network recovers, which we call “partition-resilient.”

Problem: Scalability

Our solution: Responsive Byzantine Agreement

Our “Responsive Byzantine Agreement“ reaches fast finality, which allows DEXON to support 10k transactions per second even in the testnet. In DEXON, the validators interact with each other as soon as the messages arrive so that the block confirmation time only depends on the actual network delay instead of any predetermined time bound.

Features

Reliable

DEXON possess high throughput, fast finality, and high level of network partition tolerance. DEXON is a high-performing and reliable network that can be used into a broad range of applications.

Fair

Vast numbers of stakeholders can use the DEXON Consensus Algorithm, avoiding a minority-controlled network. It solves miner centralization issues because everyone has an equal chance to propose blocks. It’s fairer for each stakeholder to benefit from, and contribute to, the network.

Friendly

DEXON provides the most developer-friendly programming languages, such as EVM and SQLVM, for developers of all levels to build their own Decentralized Applications (DApps) and prove their concepts with ease.

Key Benefits

Unbiased Randomness

DEXON’s on-chain randomness enables a more secure smart contract environment, making the randomness property in the smart contract impossible to be predicted and manipulated.

High Throughput

The DEXON Consensus Algorithm can process 10K+ transactions per second in a single shard, outperforming other popular blockchain systems.

Fast Finality

The DEXON Consensus Algorithm outperforms other popular blockchain systems as it can confirm transactions within 1 second, allowing developers to create DApps with the best user experience on DEXON.

Fully Decentralized

DEXON can scale to thousands of nodes without compromising security and speed. Current PoS blockchain systems pale in comparison with merely dozens of nodes.

Ultra Secure

The DEXON Consensus Algorithm is one of the very few algorithms that has been mathematically proven to be secure, preventing the DEXON network from being attacked by Byzantine nodes.

Low Transaction Fee

The DEXON Consensus Algorithm is efficient and does not require its network to waste energy on solving PoW puzzles. The transaction fees will thus be negligible and lower than 0.001 USD.

Application Scenarios

Due to DEXON’s high scalability, fast finality, and Byzantine fault tolerant properties, it is now feasible for any high-throughput applications to integrate decentralized ledger technology into their platform.

IoT

Ultra-secure IoT use cases are now possible with DEXON’s decentralized, high throughput, and low transaction fee network.
