type Backend

	// If the epoch requested is null, it returns the latest not-null one.
	GetTipsetByEpoch(ctx context.Context, epoch int64) (TipSet, error)
	// GetTipset returns the tipset with the given key.
	GetTipset(context.Context, gpbft.TipSetKey) (TipSet, error)
	// GetHead returns the current head tipset of the chain, which must be a
	// descendant of the latest finalized tipset.
	//
	// See Finalize.
	GetHead(context.Context) (TipSet, error)
	// GetParent returns the parent of the current tipset.
	GetParent(context.Context, TipSet) (TipSet, error)
	// GetPowerTable returns the power table at the tipset given as an argument.
	GetPowerTable(context.Context, gpbft.TipSetKey) (gpbft.PowerEntries, error)
	// Finalize marks the tipset that corresponds to the given key as finalised
	// beyond which no forks are allowed to occur. The finalised tipset overrides the
	// head tipset if it is not an ancestor of the current head.
	//
	// See GetHead.
