dev roundup
Welcome to “This Week in Quai,” a new initiative by the development company of Quai Network, Dominant Strategies. This Week in Quai will provide weekly updates to the Quai Community by aggregating and explaining popular Quai quotes, technical terms, and social posts from the past week and offering a schedule for upcoming events.

What is Quai?

Quai Network is a pre-launch cryptocurrency. Quai is the first blockchain protocol that is simultaneously decentralized, censorship resistant, and infinitely scalable. Quai, in contrast to traditional cryptocurrencies, functions as a network of many interoperable blockchains braided together. Due to a breakthrough discovery that occurred during research on Proof-of-Work, Quai Network utilizes a new consensus mechanism, Proof-of-Entropy-Minima (PoEM), which eliminates all consensus-based forks, and enables all Quai nodes to remain in “perpetual consensus.”

Quote of the Week

“Nobody knows how far you can go with a paper currency before it gets out of control, particularly if you are the world’s reserve currency.”

– Warren Buffett, May 6 2023

Warren Buffett is an American investor and philanthropist widely regarded as one of the most successful investors in the world. Offered in response to a question about the US Dollar losing its reserve status, Buffett’s quote highlights the inherent risks and uncertainties associated with traditional paper currencies, which are widely considered low-risk and certain. 

Cryptocurrencies like Quai Network, as emerging competitors to traditional paper currencies, have the potential to enable the money system to exist as an immutable protocol controlled and maintained by its users rather than as a political tool of governments.  

Technical Term of the Week

Economical Finality (or “Economically Final”): The state of a transaction on a blockchain where the cost required to modify or reverse the transaction is so high that it is no longer economically viable for an attacker to do so. Once a transaction achieves economic finality, it has an assurance that it is effectively irreversible.

Quai Network’s PoEM algorithm offers the fastest economic finality of any known consensus mechanism. Within Proof-of-Work consensus, “work” that exceeds the difficulty threshold is not counted in the system, and is effectively “thrown out.” Proof-of-Entropy-Minima, in contrast, correctly calculates and attributes all entropy removed from the system to economic finality. By discarding relevant information about work done to the system, Proof-of-Work offers significantly slower economic consensus than Proof-of-Entropy-Minima, which directly applies all entropy removal in the system to economic finality. 

Proof-of-Stake, in contrast to both Proof-of-Work and Proof-of-Entropy-Minima, is unable to offer any guarantees of economic finality due to its lack of scarcity in attestations; reorganizing a Proof-of-Stake blockchain back to any point requires social consensus amongst a group of attacking validators, which can never be mathematically proven to be unprofitable or infeasible. If a sizable group of validators in a PoS blockchain agreed to reorganize the blockchain back to a certain point, they could do so, which means that the transaction’s finality is dependent on the social consensus of validators. In contrast, PoW and PoEM blockchains require a mathematical consensus that is based on an arbitrary “work” measurement or entropy removal, respectively, which makes it much more difficult for an attacker (or attacking group) to reorganize the blockchain and reverse transactions.

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.
