Bundled Gas-free Transactions

• Every FIO Handle comes bundled with gas-free transactions.

• The number is set by the Block Producers and is currently 100.

• Most commonly used FIO Chain interactions can be gas-free and typically use up 1 or 2 bundled transactions. This means every FIO Handle owner has between 50 and 100 free FIO Chain interactions before they have to either pay for more bundled transaction or pay the gas fee.

Third Party Payment of Fees

• Certain FIO Chain transactions relating to FIO Handles and Domains can be paid for by a third party.

• Specifically, anyone can register a FIO Handle or Domain for someone else, add Bundled Transaction, or renew a FIO Domain even if they do not own it.

• This allows for a much smoother user experience, where the user does not need to acquire FIO Tokens to be able to execute these transactions, but can, for example, pay someone with a credit card.

Fee Setting

FIO Chain fees are set by Block Producers (BPs) and are intended to reflect market forces and costs of running block producing infrastructure. To accommodate this:

• Each of the 21 scheduled BPs continuously submits their desired fee amount in FIO Tokens for each blockchain interaction.

• The fee is set at median of all submitted amounts.

• The continuous nature of submissions also allows the fee to by adjusted in real-time as the market value of FIO Token changes to ensure price stability as expressed in a stable coin.

• In a similar fashion BPs decide what is the amount of bundled transaction for each new FIO Handle registered.

Fee Distribution

Fees collected on FIO Chain are distributed as follows:

Recipient

Share of fee

Block Producers - top 42 BPs, based on share of votes

36%

Block Producers - 21 active BPs scheduled when fees are distributed, divided equally

24%

Staking Reward Pool

25%

Entity facilitating transaction (TPID) or, if not provided, block producers

10%

Foundation

Although most fees are distributed within the same day, the block producer share of FIO Handle and FIO Domain registration/renewal fees are paid out over 365 days to properly incentivize block producers which will be processing bundled transactions over the full validity period.
