type ChainStore 

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

ChainStore is the main point of access to chain data.

Raw chain data is stored in the Blockstore, with relevant markers (genesis, latest head tipset references) being tracked in the Datastore (key-value store).

To alleviate disk access, the ChainStore has two ARC caches:

  1. a tipset cache
  2. a block => messages references cache.

func (*ChainStore) GetRandomness 

func (cs *ChainStore) GetRandomness(ctx context.Context, blks []cid.Cid, pers crypto.DomainSeparationTag, round abi.ChainEpoch, entropy []byte) ([]byte, error)

func (*ChainStore) GetSignedMessage 

func (cs *ChainStore) GetSignedMessage(c cid.Cid) (*types.SignedMessage, error)

func (*ChainStore) GetTipSetFromKey added in v0.2.8

func (*ChainStore) GetTipsetByHeight 

func (cs *ChainStore) GetTipsetByHeight(ctx context.Context, h abi.ChainEpoch, ts *types.TipSet, prev bool) (*types.TipSet, error)

GetTipsetByHeight returns the tipset on the chain behind 'ts' at the given height. In the case that the given height is a null round, the 'prev' flag selects the tipset before the null round if true, and the tipset following the null round if false.

func (*ChainStore) Import added in v0.2.6 

func (cs *ChainStore) Import(r io.Reader) (*types.TipSet, error)

func (*ChainStore) IsAncestorOf
