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.

# Cursor definitions (root_block_height, mblock_index, deposit_index) # (x, 0, 0): EOF # (x, 0, z), z > 0: Root-block coinbase tx (always exist) # (x, y, z), y > 0: Minor-block x-shard tx (may not exist if not neighbor or no xshard) # # Note that: the cursor must be # - EOF # - A valid x-shard transaction deposit */.

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.

DefaultTxPoolConfig contains the default configurations for the transaction pool.

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

ErrFutureBlock is returned when a block's timestamp is in the future according to the current node.

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.

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

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

ErrInvalidNumber is returned if a block's number doesn't equal it's parent's plus one.

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.

ErrPrevBlockMissing is returned if a block's previous block is not exist in DB.

ErrPrunedAncestor is returned when validating a block requires an ancestor that is known, but the state of which is not available.

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.

ErrUnknownAncestor is returned when validating a block requires an ancestor that is unknown.

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

Filter can be used to retrieve and filter logs.

GenesisAccount is an account in the state of the genesis block.
