Question 1

What is FIO?

Accepted Answer

FIO is the native utility token of FIO Chain. It is used to pay on-chain fees on the chain and supports proof-of-stake (PoS) consensus and governance, including block producer and FIO Foundation board elections.

Question 2

What are FIO's practical uses?

Accepted Answer

FIO is used to pay on-chain fees on FIO Chain, including fees to register FIO Handles and FIO Domains. A FIO Handle is a user-facing readable identifier that may be used in FIO-supported contexts as an identifier more recognizable than a long public address; a Domain forms the customizable domain-name portion of a Handle. Therefore, FIO's fee use is not an abstract description of “network gas”: registering or using these on-chain functions consumes FIO, while fees collected by the chain also enter the network's incentive-distribution mechanism.

Question 3

What happens when I stake FIO?

Accepted Answer

Holders can stake any amount of FIO in their accounts and participate in governance through voting or proxy voting. Staked tokens do not leave the account, but they are locked and cannot be spent; this means the tokens remain owned by the original account while they cannot be used for transfers or payments during the lock period. Unstaking does not immediately restore availability: when unstaking, users claim accumulated staking rewards, while the originally staked FIO remains additionally locked for 7 days. This waiting stage creates a time gap between exiting staking and reusing the principal.

Question 4

Where do FIO staking rewards come from?

Accepted Answer

The primary source of staking rewards is fees collected by FIO Chain: 25% of each fee collected is transferred to staking rewards. If the total amount transferred to the reward pool on a given day is below 25,000 FIO, the system mints tokens from the reserve to make up the difference, provided the staking reward reserve has not been exhausted, bringing that day's reward pool to 25,000 FIO. How much an individual ultimately receives is not determined solely by the amount staked; it also depends on fees processed on-chain, the amount of FIO staked across the network, and when the token began being staked after staking was enabled. Rewards are paid when unstaking, so the official documentation explicitly states that a fixed annualized return cannot be determined before staking; actual accumulated results can only be reviewed after unstaking.

Question 5

What are FIO's supply and issuance method?

Accepted Answer

FIO has a maximum supply of 1 billion tokens. At mainnet launch, tokens were allocated to the foundation, early ecosystem participants, and other stakeholders; the project did not conduct a public sale or ICO. A maximum supply does not mean all tokens are circulating at the same time. The official distribution page separately lists minting at mainnet launch and subsequent purpose-based minting, and some initial allocations were subject to programmatic locks; supply should therefore be understood by distinguishing maximum supply, minted amount, lock status, and actual circulating supply.

Question 6

What is the difference between FIO and WFIO?

Accepted Answer

FIO is the native token on FIO Chain; WFIO is the wrapped version after FIO is moved to Ethereum or Base. The official definition states that 1 WFIO always corresponds to 1 FIO, so their conversion ratio is 1:1, but they reside on different chains and can be used in different on-chain environments. Wrapping and unwrapping are completed through the decentralized FIO Bridge operated by some block producers: moving native FIO to Ethereum or Base creates WFIO; moving WFIO back to FIO Chain restores native FIO. Holding WFIO does not make it a balance that can be directly used on FIO Chain for native fees or native staking.

Question 7

How does FIO relate to network governance?

Accepted Answer

FIO is used both for PoS consensus on FIO Chain and for governance. Token holders can participate through voting or proxy voting in block producer elections and FIO Foundation board elections; the staking mechanism incentivizes this governance participation through reward accumulation. Therefore, staking is not simply a process of handing FIO to a validator in exchange for a preset return: it also involves token locking within the account, a method of governance participation, and a reward pool driven by on-chain fees.

Question 8

Are there locked FIO tokens?

Accepted Answer

FIO has historical lock arrangements. The official distribution page lists that some restricted initial allocations were gradually unlocked on specified dates after mainnet launch, with the last listed unlock date being December 10, 2022; such schedules explain when locked tokens historically became free of transfer restrictions. In addition, 38,506,000 FIO originally allocated to initial wallets that did not complete integration has been permanently locked, and the official documentation states that it will not enter circulating supply. This differs from allocations that can unlock when a time period expires.

Question 9

What role do FIO network fees play?

Accepted Answer

FIO network fees have at least two functions: users pay fees for on-chain functions, and the network then directs 25% of each fee collected into the staking reward pool. Greater fee-processing volume increases the FIO entering the reward pool on this proportional basis, but it does not mean every staker's return will necessarily rise by the same proportion. This is because an individual's allocation also depends on total staked amount and participation time after staking was enabled; moreover, when daily fee allocations are below 25,000 FIO, reserve minting makes up the difference only if the reward reserve is available.

Question 10

What are a FIO Domain and a FIO Handle?

Accepted Answer

A FIO Handle is a readable on-chain identifier in the FIO system; a FIO Domain is its customizable domain-name portion. Registering either a Handle or a Domain is an on-chain operation on FIO Chain and requires paying the corresponding registration fee in FIO. Their relationship is like that between a complete identifier and its domain-name portion: a Domain can provide a namespace for organizing or customizing multiple Handles, but specific availability for registration and fees still depend on on-chain rules and availability at the time.

Question 11

Are FIO staking returns fixed?

Accepted Answer

FIO staking returns are not fixed annualized returns. Rewards are jointly affected by fees actually processed by FIO Chain, the total amount staked across the network, and when users begin staking after staking is enabled; users claim accumulated rewards when unstaking, at which point they can review the actual result for that period. The daily 25,000 FIO rule is a mechanism for supplementing the reward pool when fees are insufficient and the staking reward reserve has not been exhausted. It is not a return commitment to each staker and cannot be used to directly derive APY.

Question 12

What are subsequently minted FIO tokens used for?

Accepted Answer

Subsequent minting is allocated to purposes such as the foundation reserve, new-user incentives, the staking reward reserve, and the block producer reserve, rather than being arbitrary additional issuance. The official distribution page shows that the foundation reserve totaled 181,253,654 FIO and was exhausted in July 2023; the block producer reserve totaled 20,000,000 FIO and is also shown as exhausted. The staking reward reserve is used to supplement the reward pool when the 25% allocated from daily fees is below 25,000 FIO; new-user incentives are provided to application providers such as integrated wallets and exchanges to temporarily increase the proportion of transaction-fee distributions they receive. Both uses are subject to their respective reserves and rules and must not be conflated with the exhausted foundation or block producer reserves.
