Gurhan Kiziloz has taken BlockDAG into direct competition with Ethereum and Solana after building Nexus International to $1.2 billion in annual revenue for 2025. The source article also frames his background around a $1.7 billion track record. From the outset, BlockDAG is presented as a project aimed at the two networks that have shaped much of the current blockchain market: Ethereum for smart contracts and Solana for speed.
BlockDAG pitches parallel processing instead of linear block production
The project’s core claim is architectural. Rather than adding blocks one after another on a single chain, BlockDAG uses a Directed Acyclic Graph structure that processes transactions in parallel. The article says this can raise throughput to thousands of transactions per second, instead of the dozens typically associated with older chain designs. Speed, though, is not the only message. Solana already owns much of that narrative, so BlockDAG is trying to pair performance with a different security and decentralization model.
According to the source, critics have argued that Solana’s validator requirements can favor well-capitalized operators, and the network has experienced outages during periods of heavy demand. BlockDAG keeps Proof-of-Work, which the article says distributes security across a broader base. It also claims compatibility with Ethereum’s smart contract ecosystem, allowing developers to migrate applications without rebuilding them from scratch. The pitch is straightforward: offer Solana-like speed while addressing weaknesses that some observers associate with Solana’s design.
Self-funded development and direct management intervention
The article says BlockDAG has been funded directly by Kiziloz rather than through venture capital. That approach is described as a way to keep outside investors from dictating pace or direction. When development slowed, he reportedly stepped in himself, removed the CEO, and let go of staff who could not keep up with the standards he expected. The restructuring was described as fast and deliberate.
That management style is also tied to the project’s delivery record. The source says BlockDAG’s roadmap has stayed on schedule and features have shipped when planned. In a sector where delays are common, the article presents this as unusual. It credits that outcome to Kiziloz’s emphasis on rapid execution, strict accountability, and close operational control.
Competing with Ethereum and Solana means overcoming existing network effects
The piece also makes clear that the challenge is larger than raw technology. Ethereum continues to build out its Layer 2 ecosystem to address scaling limits without giving up base-layer security. Solana’s developer base remains active, and adoption has continued despite its history of service interruptions. BlockDAG is entering a market where incumbents already have brand recognition, developers, liquidity, and years of accumulated network effects. That raises a practical question: whether builders and users will move.
The article links this strategy to Kiziloz’s earlier bets, including a $200 million investment in Spartans.com against Bet365 and Stake, which it says is paying off. In that framing, BlockDAG is another execution-driven wager built on architecture, decentralization claims, and founder-led control. The source also states that the article was prepared in collaboration with BlockDAG and does not constitute investment advice.
