consensus
As an Austin-based organization, we are thrilled to welcome the global crypto community to Austin, Texas for Consensus 2022.

Quai Network has maintained long-standing partnerships with ATXDAO, Texas Blockchain, and other local crypto organizations, sponsoring a series of prior Austin crypto events.

We are sponsoring two events during Consensus to connect with community members and crypto enthusiasts from around the world!

First, is the Texas Blockchain Welcome Reception on Wednesday, June 8th. Texas Blockchain is the leading University Blockchain club in Texas, and we can’t think of a better group of individuals to help kick off Consensus. Come meet the Quai team and the best collegiate club at UT!

Learn more about the event and RSVP to the Texas Blockchain Welcome Reception here: https://events.coindesk.com/consensus2022/agenda/session/914371

Next, we’ll be sponsoring KEEP AUSTIN WEB3 with ATXDAO on June 10, 2022. With performances from Cedric Gervais and PLS&TY, a dedicated Quai booth, and hosted by the city DAO, this is an event you won’t want to miss.

Learn more about the event and RSVP to KEEP AUSTIN WEB3 here: https://www.atxdao.com/rsvp

The majority of our team will be in attendance at Consensus, for both the listed events, and more! Some people to keep an eye out for:

  • Alan Orwick: Co-Founder of Quai Network and CEO of Dominant Strategies
  • Dr. K: Co-Founder of Quai Network and Advisor at Dominant Strategies
  • Raleigh Moore: CMO at Quai Network and Dominant Strategies
  • Sriram Vishwanath: Advisor for Quai Network and Dominant Strategies
  • Shreekara Shastry: Core developer for Quai Network and lead engineer at Dominant Strategies

Make sure to swing by our events for some good conversation, food, drinks, music, and more!

Join us to build a better blockchain.

Quai Network is an open-source Proof-of-Entropy-Minima blockchain network utilizing the capabilities of merged mining to increase throughput and security. Users of Quai Network will enjoy fast transaction times without compromising decentralization and security. Miners will have competitive mining opportunities across the many blockchains within the network.

Capable of thousands of transactions per second, the Quai Network is a new solution to scalability that is soon to be ready for mainnet release.

Security

All Quai Network blockchains are braided together, keeping the entire network censorship resistant and secure creating Scalable Proof-of-Work.

Decentralization

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.

Scalability

Quai Network automatically expands with demand to upwards of 50,000 TPS while keeping fees under $0.01.

Consensus

Transactions in Quai Network can be locally confirmed prior to global confirmation, offering high throughput with the shortest possible time to economic finality.

Shared Security

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.

Merge-Mined Parachains

Parachains inherit security and interoperability by merged mining with Quai Network, and create new incentives for miners and users.

The Prime Chain

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.

Sub Networks

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.
