All Quai Network blockchains are braided together, keeping the entire network censorship resistant and secure creating Scalable Proof-of-Work.
Quai allows anyone to participate in network governance by running a node or miner. With thousands of participants distributed across the globe, there is no single party with the ability to modify or turn off the network, ensuring zero network downtime.
Quai Network automatically expands with demand to upwards of 50,000 TPS while keeping fees under $0.01.
Transactions in Quai Network can be locally confirmed prior to global confirmation, offering high throughput with the shortest possible time to economic finality.
All blockchains within Quai Network share Proof-of-Work security through merged mining. Every Quai transaction is eventually confirmed by 100% of network hash power.
Parachains inherit security and interoperability by merged mining with Quai Network, and create new incentives for miners and users.
The Prime blockchain acts as the "knot" tying all Quai Network chains together. The Prime blockchain braids sub networks together, facilitating the transfer of data across chains.
Quai's many high-speed sub networks independently and asynchronously process transactions. All sub networks are braided together by the Prime chain, ensuring shared security and interoperability across the network.
> Quai Network is a set of EVM-compatible blockchains that achieves 50,000+ TPS without compromising decentralization.
Quai Network is transforming the world of blockchain with the first decentralized energy dollar, $Qi, designed to provide predictable value and facilitate seamless transactions on the only scalable and programmable Proof-of-Work blockchain. Our vision is to create a financial system that is transparent, secure, and fair, empowering individuals to transact freely without intermediaries.
Experience ultra-fast transactions with throughput up to 50,000 TPS, all at incredibly low fees – less than a penny per transaction, today and every day. 'A Penny Today, a Penny Tomorrow, a Penny in Perpetuity.' Our platform is built on a seamless, homogeneous layer, ensuring swift finalization. This robust design is resilient to censorship and fortified against adversarial threats, offering you a secure and efficient transaction experience.
Quai Network features EVM-compatible smart contracts, as well as MEV-resistant transaction ordering, ensuring more equitable and efficient execution in DeFi markets. Additionally, we've implemented work-based primitives and proofs, which enables the transfer of hash compute power, truly decentralized infrastructure and other markets for digitally-native resource markets.
The first truly decentralized monetary system, unifying all three functions of money with breakthrough scalability.
One Prime chain, three Region chains, and nine Zone chains form a hierarchy. Every miner simultaneously checks their hash against all three difficulty levels — a single computation secures the entire network. No extra energy, no extra hardware. A 51% attack on any chain requires 51% of total network hashpower.
Learn about merged mining +QUAI is an EVM-compatible token with logarithmic emission — increasingly scarce over time, like digital gold. QI is a UTXO-based token with linear emission tied to mining difficulty, making it a decentralized stablecoin backed by real energy cost. Miners choose which to earn. Anyone can convert between them at the protocol-set rate.
Learn about token dynamics +Traditional blockchains fork when two miners find a block at the same time. Quai’s consensus mechanism, PoEM, measures the intrinsic entropy each block removes from the hash space. Every node always picks the same winner — no forks, no ambiguity, no wasted work. Consensus is instant and objective.
Learn about PoEM +QUAI functions like Bitcoin for storing value, while QI provides cash-like privacy for transactions.
