Types

type Manager

type Manager struct {
	// contains filtered or unexported fields
}

A Manager manages the current state of the blockchain.

func NewManager

func NewManager(cs modules.ConsensusSet) (*Manager, error)

NewManager creates a new chain manager.

func (*Manager) AcceptBlock

func (m *Manager) AcceptBlock(b types.Block) error

AcceptBlock adds b to the consensus set.

func (*Manager) BlockAtHeight

func (m *Manager) BlockAtHeight(height uint64) (types.Block, bool)

BlockAtHeight returns the block at the given height.

func (*Manager) Close

func (m *Manager) Close() error

Close closes the chain manager.

func (*Manager) IndexAtHeight
