Package state provides a caching layer atop the Ethereum state trie.

Package types contains data types related to Ethereum consensus.

Package vm implements the Ethereum Virtual Machine.

AccumulateRewards credits the coinbase of the given block with the mining reward.

CalcDifficulty is the difficulty adjustment algorithm.

CalcGasLimit computes the gas limit of the next block after parent.

CalcTD computes the total difficulty of block.

Canary will check the 0'd address of the 4 contracts above.

GenerateChain creates a chain of n blocks.

GenesisBlockForTesting creates a block in which addr has the given wei balance.

GetBlockByHash returns the block corresponding to the hash or nil if not found.

GetBlockByHash returns the canonical block by number or nil if not found.

GetBlockReceipts returns the receipts generated by the transactions included in block's given hash.

GetReceipt returns a receipt by hash.

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

IsBlockNonceErr returns true for invalid block nonce errors.

Creates and returns a `BlockCache` with `size`.

Create a new filter which uses a bloom filter on blocks to figure out whether a particular block is interesting or not.

PutBlockReceipts stores the block's transactions associated receipts and stores them by block hash in a single slice.

PutReceipts stores the receipts in the current database.

PutTransactions stores the transactions in the given database.

ReportBlock reports the block to the block reporting tool found at badblocks.ethdev.com.

See YP section 4.3.4.

WriteBlock writes a block to the database.

WriteGenesisBlock writes the genesis block to the database as block number 0.

WriteHead force writes the current head.

must be bumped when consensus algorithm is changed, this forces the upgradedb command to be run (forces the blocks to be imported again using the new algorithm).

Set of manually tracked bad hashes (usually hard forks).

DisabledBadBlockReporting can be set to prevent blocks being reported.

Transaction Pool Errors.

BlockCache implements a caching mechanism specifically for blocks and uses FILO to pop.

BlockGen creates blocks for testing.

BlockNonceErr indicates that a block's nonce is invalid.

ChainSplit is posted when a new head is detected.

FakePow is a non-validating proof of work implementation.

Filtering interface.

NewBlockEvent is posted when a block has been imported.

NewMinedBlockEvent is posted when a block has been imported.

Parent error.

Mining operation events.

* 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 all the necessary work to work out a valid new state root.

TxPool contains all currently known transactions.

TxPostEvent is posted when a transaction has been processed.

TxPreEvent is posted when a transaction enters the transaction pool.

Block validation error.

TODO move this to types?.

Message represents a message sent to a contract.
