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.

ErrNoGenesis is returned when there is no Genesis Block.

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.

ErrOnlyOwner is returned if modifying providers transaction is not from owner of enterprise contract.

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

ErrProviderInsufficientFunds is returned if the transaction fee is higher than the balance of the provider's account (fee's paid by provider).

ErrProviderSignatureIsRequired is returned if the transaction to enterprise contract does not contain a provider signature.

ErrRedundantProviderSignature is returned if the transaction does not require provider to sign but still contains a provider's signature.

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

ErrOversizedData is returned if new tx has the same nonce with an old one.

ErrSenderInsufficientFunds is returned if the transaction value is higher than the balance of the user's account (fee's paid by provider).

ErrTxPoolFull is returned tx pool is full.

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.

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).

Genesis specifies the header fields, state of a genesis block.
