Question 1

What is QUAI?

Accepted Answer

QUAI is Quai Network's native EVM-compatible asset, which can be used for transfers, smart contracts, and interactions with on-chain applications. The project positions it as a scarce reserve asset and designs it with declining issuance; this protocol positioning does not guarantee its price, liquidity, or usage demand.

Question 2

How does Quai Network scale transaction processing capacity?

Accepted Answer

Quai organizes the chain into three levels: Prime, Region, and Zone. Prime coordinates Regions, and Regions in turn coordinate Zones, which actually execute transactions. Through merged mining, miners can use the same hash work to secure Prime, Region, and Zone simultaneously, so adding chains does not require dividing security among individual subchains; multiple Zones can execute transactions in parallel. PoEM is used to enable nodes to reach agreement on blockchain headers, helping these levels remain coordinated.

Question 3

What is the difference between QUAI and QI?

Accepted Answer

QUAI and QI are both native assets of Quai Network, but they use different ledgers and serve different roles. QUAI is an EVM-compatible account-based asset whose balances are recorded by account, making it suitable for smart contracts and application interactions; QI is a UTXO-based asset whose transactions spend unspent outputs and create new output records, and the project positions it as a medium of exchange priced in energy. The protocol supports native conversion between them, but conversion does not change their respective ledger models, issuance logic, or use cases. Users should still confirm which asset an application supports before using it.

Question 4

How is QUAI issued?

Accepted Answer

QUAI is issued through open proof-of-work mining: miners contribute computing resources to compete to produce blocks that meet the rules, and receive issuance rewards under protocol rules after a block is accepted by the network. Quai designs QUAI with declining issuance, meaning that as the rules progress, the scale of new issuance trends downward. Proof of work describes the path for security participation and new coin creation; the actual tradable supply also depends on the holding and transfer of issued assets and changes to protocol rules.

Question 5

Have QUAI's supply rules changed?

Accepted Answer

Yes. The Singularity fork on March 19, 2026 executed a supply reset at Prime block 1,530,500, removed future unlocks, and increased the number of includable workshares from 16 to 32. The removal of future unlocks applied to portions that had not yet been released under the previous unlock schedule; it differs from issuance rewards continuously generated through open mining in subsequent blocks. Therefore, when understanding the current supply, do not simply apply the pre-upgrade unlock schedule; instead, consider this reset, subsequent mining issuance, and the on-chain state at that time separately.

Question 6

When did Quai Network launch its mainnet?

Accepted Answer

Quai Network launched its mainnet at genesis on February 4, 2025, with the Cyprus-1 Zone online, chain ID 9, and GPU mining open from the first block. Public mining began on February 5; account-ledger QUAI transfers and application deployment opened on February 19. Genesis, the opening of mining, and the opening of asset transfers were distinct stages: the first put the mainnet into operation under its rules, while the latter two respectively opened security participation and actual asset and application operations.
