Overview ¶

Package dag provides DAG consensus functionality

Package dag implements consensus for Directed Acyclic Graphs.

DAG handles parallel transactions with causal dependencies, where vertices can reference multiple parents. The consensus pipeline flows: photon → wave → focus → (prism + horizon) → flare → nebula. This enables concurrent transaction processing while respecting causality.

Types ¶

type Engine ¶

type Engine interface {
	// GetVtx gets a vertex by ID
	GetVtx(context.Context, ids.ID) (Transaction, error)

	// BuildVtx builds a new vertex
	BuildVtx(context.Context) (Transaction, error)

	// ParseVtx parses a vertex from bytes
	ParseVtx(context.Context, []byte) (Transaction, error)

	// Start starts the engine
	Start(context.Context, uint32) error

	// Shutdown shuts down the engine
	Shutdown(context.Context) error
}

Engine defines the DAG consensus engine interface

func New ¶

func New() Engine

New creates a new DAG engine

type Transaction ¶

type Transaction interface {
	ID() ids.ID
	Parent() ids.ID
	Height() uint64
	Bytes() []byte
	Verify(context.Context) error
	Accept(context.Context) error
	Reject(context.Context) error
}

Transaction represents a DAG transaction

type Tx ¶

type Tx interface {
	ID() ids.ID
	ParentIDs() []ids.ID
	Bytes() []byte
	Verify(context.Context) error
	Accept(context.Context) error
	Reject(context.Context) error
}

Tx represents a transaction in the DAG
