Package bloombits implements bloom filtering on batches of data.

Package vm implements the Ethereum Virtual Machine.

ApplyMessage computes the new state by applying the given message against the old state within the environment.

ApplyTransaction attempts to apply a transaction to the given state database and uses the input parameters for its environment.

IntrinsicGas computes the 'intrinsic gas' for a message with the given data.

NewEVMTxContext creates a new transaction context for a single transaction.

NewStateTransition initialises and returns a new state transition object.

NewTxPool creates a new transaction pool to gather, sort and filter inbound transactions from the network.

validateTx checks whether a transaction is valid according to the consensus rules and adheres to some heuristic limits of the local node (price and size).

DefaultTxPoolConfig contains the default configurations for the transaction pool.

ErrBannedHash is returned if a block to import is on the banned list.

ErrFeeCapTooLow is returned if the transaction fee cap is less than the the base fee of the block.

ErrFeeCapVeryHigh is a sanity error to avoid extremely big numbers specified in the fee cap field.

ErrGasLimitReached is returned by the gas pool if the amount of gas required by a transaction is higher than what's left in the block.

ErrGasUintOverflow is returned when calculating gas usage.

ErrInsufficientFunds is returned if the total cost of executing a transaction is higher than the balance of the user's account.

ErrInsufficientFundsForTransfer is returned if the transaction sender doesn't have enough funds for transfer(topmost call only).

ErrIntrinsicGas is returned if the transaction is specified to use less gas than required to start the invocation.

ErrKnownBlock is returned when a block to import is already known locally.

ErrNoGenesis is returned when there is no Genesis Block.

ErrNonceMax is returned if the nonce of a transaction sender account has maximum allowed value and would become invalid if incremented.

ErrNonceTooHigh is returned if the nonce of a transaction is higher than the next one expected based on the local chain.

ErrNonceTooLow is returned if the nonce of a transaction is lower than the one present in the local chain.

ErrOversizedData is returned if the input data of a transaction is greater than some meaningful limit a user might use.

ErrSenderNoEOA is returned if the sender of a transaction is a contract.

ErrTipAboveFeeCap is a sanity error to ensure no one is able to specify a transaction with a tip higher than the total fee cap.

ErrTipVeryHigh is a sanity error to avoid extremely big numbers specified in the tip field.

ErrTxTypeNotSupported is returned if a transaction is not supported in the current network configuration.

ExecutionResult includes all output after executing given evm message no matter the execution itself is successful or not.

The State Transitioning Model A state transition is a change made when a transaction is applied to the current world state The state transitioning model does all the necessary work to work out a valid new state root.

TxPool contains all currently known transactions.

TxPoolConfig are the configuration parameters of the transaction pool.

Message represents a message sent to a contract.

GasPool tracks the amount of gas available during execution of the transactions in a block.
