gas

README

The gas package contains the necessary code for estimating and pricing l1 gas. Currently it's mostly barebone placeholders, but will evolve into precompiled smart contracts and binders for accessing their state in order to fit it in the gas mechanics.

Functions

func CalculateL1GasUsed

func CalculateL1GasUsed(data []byte, overhead *big.Int) *big.Int

CalculateL1GasUsed - calculates the gas cost of having a transaction on the l1.

Types

type ObscuroGasPool

type ObscuroGasPool struct {
	// contains filtered or unexported fields
}

func NewObscuroGasPool

func NewObscuroGasPool(gp *gethcore.GasPool) *ObscuroGasPool

func (*ObscuroGasPool) ForTransaction

func (gp *ObscuroGasPool) ForTransaction(tx *types.Transaction) (*gethcore.GasPool, error)

type Oracle

type Oracle interface {
	ProcessL1Block(block *types.Block)
	EstimateL1StorageGasCost(tx *types.Transaction, block *types.Block) (*big.Int, error)
	EstimateL1CostForMsg(args *gethapi.TransactionArgs, block *types.Block) (*big.Int, error)
