Concepts

Resources and fees

At launch the unified fee is GB · Free Signature: a daily quota of weighted bytes. Signatures are not billed; only the shortfall burns coin.

Model

One launch rail: GB

From GB_FEE_HEIGHT (0 on the delivery genesis), legacy energy and bandwidth collapse into one counter. Below the fork the node still computes the old pair.

GB (quota): Weighted bytes per day: useful tx size × type factor. PQ/ECDSA signatures are excluded.
Type factor: The factor reuses the old energy table (TRANSFER=1, deploy=10…). It only weights size — not a second rail.
Fee: Shortfall × 5 e7 per weighted byte, BURNED. It does not go to the producer. The fee field is only the authorized ceiling.

Quotas

How much you have, and when it comes back

The quota grows with effective stake — your own, minus what you delegated out, plus what you received. Linear regeneration over ~24 h of blocks.

GB · Free Signature model

resourceStake = staked - delegatedOut + delegatedIn      (em EAV7 inteiro)

maxGb = 1_000_000_000 + resourceStake × 1_000_000
#             1 GB base                 + 1 MB por EAV7 staked

# bytes ponderados = max(MIN_WEIGHTED, tamanho_útil × fator(tipo))
# tamanho_útil exclui signature / pqSignature / id (anti-maleabilidade)

# regeneração linear e preguiçosa ao longo de 86 400 blocos (~24 h a 1 bloco/s)
usado = max(0, usadoRegistrado - floor(maxGb × blocosDecorridos / 86400))
disponível = max(0, maxGb - usado)

# o que faltar vira QUEIMA, não pagamento ao produtor
taxa = shortfall_bytes × 5 e7

GB.DAILY_BYTES: 1 000 000 000Base quota: 1 GB/day in weighted bytes (no stake).
GB.PER_STAKED_EAV7: 1 000 0001 MB extra per whole EAV7 of effective stake.
GB.MIN_WEIGHTED: 1 024Minimum weighted consumption per tx (anti empty-tx spam).
BANDWIDTH.BURN_PER_BYTE: 5 e7Burn per weighted byte beyond the quota.
REGEN_BLOCKS: 86 400Blocks for a full regeneration — at 1 block/s, about 24 hours.

Burn

What a GB shortfall costs

The conversion is direct and deflationary: every weighted byte you were short becomes destroyed EAV7. No validator is paid for it.

ENERGY.BURN_PER_ENERGY: 20 000 e7Legacy (pre-fork): price of one energy unit outside the quota.
BANDWIDTH.BURN_PER_BYTE: 5 e7Price of one weighted byte the GB quota did not cover.
MAX_FEE_LIMIT: 100 000 000 e7Absolute ceiling of any transaction's fee field.

fee is a LIMIT, not a price

The fee field authorizes a maximum burn. If the computed GB shortfall burn exceeds that ceiling, mempool/execution rejects — stake or raise the limit. A high fee does not speed inclusion.

Exemption

Stake buys resource, not priority

Two distinct effects that are easy to conflate: stake raises the resource quota, and past a floor it exempts the account from fees entirely.

FEE_EXEMPT_STAKE: 100 000 000 e7 · 100 EAV7At or above this stake, the account is marked feeExempt.
feeExempt: Returned by /address/:end. An exempt account burns no fee even when it blows the quota.
DELEGATE_RESOURCE: Sponsors resource for another account without transferring ownership of the stake.

The sponsored-wallet pattern

An application can stake on a central account and delegate resource to its users' accounts. They transact without ever buying EAV7 — and the stake stays yours.

Table

Weighting factor by type

Inherited from the energy table. Multiplies useful tx bytes in the GB calculation.

Type	Factor	Note
`TRANSFER`	`1`	The protocol's base case.
`TOKEN_TRANSFER`	`2`	Moving an EAV20 balance costs twice a native transfer.
`NFT_MINT`	`3`	Minting an EAV721 item.
`AI_TASK`	`5`	Opens a task for the oracle network.
`EAVM_CALL`	`5`	Contract call. Execution gas converts at GAS_PER_ENERGY = 100.
`SLASH_DOUBLE_SIGN`	`8`	Double-sign report — deliberately expensive, to discourage frivolous reports.
`TOKEN_CREATE`	`10`	Token creation, the top of the table alongside deployment.
`EAVM_DEPLOY`	`10`	Publishing bytecode to the EAVM.

A type missing from the table counts as factor 1.
