NewStateProcessor initialises a new StateProcessor.

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.

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

SetReceiptsData computes all the non-consensus fields of the receipts.

SetupGenesisBlock writes or updates the genesis block in db.

Transfer subtracts amount from sender and adds amount to recipient using the given Db.

BadHashes represent a set of manually tracked bad hashes (usually hard forks).

DefaultTxPoolConfig contains the default configurations for the transaction pool.

ErrBlacklistedHash is returned if a block to import is on the blacklist.

fetch number of newBlock exceed specified number.

ErrGasLimit is returned if a transaction's requested gas limit exceeds the maximum allowance of the current block.

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.

ErrInsufficientFundsForPayer is returned if the total gascost of executing a transactionis higher than the balance of the payer's account.

ErrInsufficientFundsForSender is returned if the amount of executing a transactionis 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.

ErrInvalidPayer is returned if the transaction contains an invalid payer's signature.

ErrInvalidSender is returned if the transaction contains an invalid signature.

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

ErrNegativeValue is a sanity error to ensure noone is able to specify a transaction with a negative value.

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.

ErrReplaceUnderpriced is returned if a transaction is attempted to be replaced with a different one without the required price bump.

ErrUnderpriced is returned if a transaction's gas price is below the minimum configured for the transaction pool.

BlockChain represents the canonical chain given a database with a genesis block.

BlockGen creates blocks for testing.

BlockValidator is responsible for validating block headers, uncles and processed state.

BloomIndexer implements a core.ChainIndexer, building up a rotated bloom bits index for the Ethereum header bloom filters, permitting blazing fast filtering.

CacheConfig contains the configuration values for the trie caching/pruning that's resident in a blockchain.

ChainIndexer does a post-processing job for equally sized sections of the canonical chain (like BlooomBits and CHT structures).
