An In-Depth Analysis of the BlockDAG: A Parallelized Blockchain Architecture Breaking Through Scalability Limits

The starting point and historical evolution of BlockDAG technology

BlockDAG integrates the multi-chain parallel concept of DAG with the security guarantees of traditional Blockchain. The original DAG technology was promoted by projects such as IOTA and Nano, primarily addressing the scalability bottleneck of existing chain architectures, but security and decentralization still need to be strengthened. BlockDAG achieves a new balance between efficiency and security by adopting Proof of Work (PoW) or Proof of Stake (PoS) and integrating the PHANTOM and GHOSTDAG algorithms, becoming a significant milestone in breaking through the performance limits on-chain.

Team Background and Key Figures

BlockDAG is led by Antony Turner (CEO) from SwissOne Capital, with technology spearheaded by blockchain and AI expert Jeremy Harkness (CTO), and smart contract audits conducted by security expert Youssef Khaoulaj, forming a robust and professional core team that ensures ongoing innovation and security of the protocol.

Efficient Consensus Algorithm: PHANTOM and GHOSTDAG

The PHANTOM algorithm performs fine-grained topological sorting of all blocks in the DAG, distinguishing between honest and malicious blocks to construct a “heavy subgraph” of predominantly honest blocks, effectively resisting attacks. Based on this, GHOSTDAG quickly selects the heaviest subgraph according to block weight, accelerating consensus convergence, suitable for a high-frequency generated parallel block environment, fundamentally improving TPS to tens of thousands per second, ensuring second-level confirmation.

The core advantages of BlockDAG

BlockDAG supports high parallel processing, easily handling real-time payments and high-frequency trading scenarios. It also employs a multi-referencing strategy to ensure the network’s decentralization and resistance to attacks. It is compatible with the Ethereum Virtual Machine (EVM) and MetaMask, facilitating seamless migration of existing dApps and promoting rapid ecological expansion. The architecture design also emphasizes reducing transaction costs and energy consumption, while considering environmental protection.

BDAG Token Economic System and Uses

The total supply of BDAG is 150 billion pieces, with allocations covering pre-sales, miners, community, liquidity, and team, among others. A halving issuance is implemented annually, similar to Bitcoin’s halving mechanism, to ensure the token’s scarcity. Users can mine and stake BDAG through the X1 Miner to earn rewards, while liquidity incentives within the ecosystem promote active trading.

Development Roadmap and Market Outlook

The mainnet is officially launched in the second half of 2025, enhancing support for applications such as stablecoins, cross-chain bridges, DeFi, and NFTs. The current presale price of BDAG is approximately 0.002 USD, and if the market is active, it is expected to break through 0.005 USD and challenge higher price levels.

Risk and Investment Advice

Investors should pay attention to regulatory risks, delays in mainnet development, and market competition pressure when participating. Competitors include other DAG and Layer-1 projects, which may affect the competition for ecological resources. It is recommended that beginners conduct rational analysis and diversify their investments, closely track project progress and market reactions to reduce potential losses.
