01Overview
What is BlockDAG?
BlockDAG is a Layer-1 blockchain network built around a Directed Acyclic Graph architecture. The design combines graph-based transaction relationships with Proof-of-Work and an EVM-compatible environment.
DAG
DAG Architecture
A graph-based structure that represents relationships between blocks and transactions beyond a single linear sequence.
02PoW
Proof-of-Work
A consensus mechanism based on computational work that contributes to network security and decentralized participation.
0302Context
Why blockchain architecture matters
Blockchain networks need to balance transaction processing, security, decentralization and scalability. Architecture plays a central role in how these properties are approached.
02Architecture is a set of choices — each one creates a different path through the network.
Transaction Throughput
Network architecture influences how transaction activity is organized and processed as usage grows.
Network Congestion
Different approaches to data and block organization create different trade-offs during periods of activity.
Scalability
Scalable infrastructure needs to accommodate increasing activity while maintaining core protocol properties.
Consensus Design
The consensus mechanism determines how participants coordinate and validate network state.

How does BlockDAG work?
Explore the basic flow from transaction creation to network confirmation.
BLOCKDAG / FLOWGRAPH 001
01
Transaction creation
A transaction enters the network.
02
Network propagation
Information is propagated across participating nodes.
03
DAG structure
Blocks can form multiple relationships within the graph.
04
Consensus
Protocol rules and Proof-of-Work contribute to consensus.
05
Confirmation
The network processes transactions according to protocol rules.
04DAG
Understanding Directed Acyclic Graph architecture
A Directed Acyclic Graph, or DAG, is a graph structure in which relationships follow directed paths without forming circular loops.
Traditional linear structure
Block→Block→Block
A conventional blockchain organizes blocks in a sequential chain.
DAG-based structure
A graph-based architecture can represent multiple relationships between blocks.

06Consensus
Why Proof-of-Work?
Proof-of-Work uses computational work as part of a network's consensus and security model.
01
Network Security
Computational work can make it costly to alter or manipulate network history under the protocol's security assumptions.
02
Decentralized Participation
Independent participants can contribute computational resources to the network.
03
Consensus
Protocol rules determine how valid network activity is recognized and incorporated into the network state.
