DIESEL

DIESEL is the protocol's native token. Unlike frBTC, which is backed by locked Bitcoin, DIESEL is emitted on-chain: it is minted as new blocks are produced, following a schedule tied to Bitcoin itself.

How DIESEL is issued

Every Bitcoin block emits the same amount of DIESEL as it emits new bitcoin. Today that is 3.125 per block, and it halves alongside Bitcoin, on the same 210,000-block schedule. When Bitcoin's subsidy drops to 1.5625, DIESEL's does too.

Per block	3.125 DIESEL
Per day	about 450 DIESEL
Per year	about 164,000 DIESEL
Halving	every 210,000 blocks, with Bitcoin

DIESEL is not printed on demand. There is no faucet and no way to issue it faster: it appears only as Bitcoin blocks appear, which ties the supply side of the SUBFROST economy directly to Bitcoin's own monetary schedule.

Who receives it

A block's DIESEL is split two ways:

• A share goes to the protocol, sized in parity with the miner fees in that block and capped at half of the block's DIESEL. A block with heavy fee activity sends more to the protocol, up to that ceiling.
• The rest is divided among everyone who minted in that block, evenly.

So your share depends on how many others minted at the same height. This is the part worth internalising before you mint: the block's emission is fixed, so a crowded block pays each participant proportionally less.

What DIESEL is for

• It anchors the core AMM pool. DIESEL pairs with frBTC in the protocol's central liquidity pool, giving SUBFROST a native unit of account. Providing liquidity to that pool is also what earns FIRE.
• It is earned by participation. Because DIESEL is distributed as blocks are produced, participants who interact with the protocol can receive a share of the emission.
• It is used in routing. DIESEL is a common intermediate hop when a swap has no direct pool (see Swap).
