}

Context is information about the current execution. [NetworkID] is the ID of the network this context exists within. [ChainID] is the ID of the chain this context exists within. [NodeID] is the ID of this node

func (*Context) Bootstrapped

func (ctx *Context) Bootstrapped()

Bootstrapped marks this chain as done bootstrapping

func (*Context) Epoch

func (ctx *Context) Epoch() uint32

Epoch this context thinks it's in based on the wall clock time.

func (*Context) IsBootstrapped

func (ctx *Context) IsBootstrapped() bool

IsBootstrapped returns true iff this chain is done bootstrapping

type EventDispatcher

type EventDispatcher interface {
	Issue(ctx *Context, containerID ids.ID, container []byte) error
	// If the returned error is non-nil, the chain associated with [ctx] should shut
	// down and not commit [container] or any other container to its database as accepted.
	// Accept must be called before [containerID] is committed to the VM as accepted.
	Accept(ctx *Context, containerID ids.ID, container []byte) error
	Reject(ctx *Context, containerID ids.ID, container []byte) error
}
