The Vertical That Breaks Founders: How Gurhan Kiziloz Made BlockDAG Win

Blockchain does not forgive weakness. It is an industry built on cryptographic rigour, adversarial economics, and communities that will tear apart any project that shows hesitation. The graveyard of failed tokens, abandoned protocols, and disgraced founders stretches back over a decade. For every Ethereum, there are a thousand projects that promised revolution and delivered nothing. This is the arena Gurhan Kiziloz chose to enter. And this is the arena where he is winning.

BlockDAG is not a success because the technology is elegant, though it is. It was not a success because the market was ready, though it was. BlockDAG is a success because Kiziloz refused to let it be anything else. He took a blockchain with potential and subjected it to the same operational intensity that built Nexus International into its record of $1.2 revenue in 2025. The results speak for themselves.

The blockchain vertical is uniquely punishing. Unlike gaming, where Kiziloz made his fortune, blockchain combines technical complexity with regulatory uncertainty, global competition, and a user base that treats scepticism as a virtue. Projects must deliver working technology, build developer ecosystems, navigate legal frameworks across dozens of jurisdictions, and maintain community trust, simultaneously. Most founders are not equipped for this. Most projects collapse under the weight of competing demands. BlockDAG has not collapsed. It has accelerated.

The acceleration came at a cost. Kiziloz made decisions that other founders would have delayed, delegated, or avoided entirely. When BlockDAG's CEO could not match the pace he demanded, Kiziloz removed him. Staff who were not contributing to forward momentum followed. These were not ceremonial changes designed to appease stakeholders. They were surgical interventions designed to eliminate drag. Kiziloz identified what was slowing the company down and he cut it out.

This is not a management style taught in business schools. It is not a management style that wins industry awards for workplace culture. But it is a management style that delivers. BlockDAG now operates with a team calibrated entirely for speed and execution. Every person who remains has survived the filter. Every person who remains understands what is expected. The organisation does not carry passengers.

The blockchain industry has seen technical founders who could not operate. It has seen operators who could not understand the technology. Kiziloz is neither. He grasps the architecture, the Directed Acyclic Graph structure that enables parallel processing, the Proof-of-Work consensus that ensures decentralisation, the EVM compatibility that allows developer migration. And he grasps what is required to turn architecture into adoption: relentless execution, zero tolerance for underperformance, and a willingness to make the hard calls that separate surviving projects from dead ones.

The challenges he faced were not abstract. Blockchain development requires coordinating distributed teams across time zones. It requires managing open-source communities with competing agendas. It requires shipping code that will secure billions of dollars in value while being scrutinised by adversaries looking for any vulnerability. It requires doing all of this while competitors with deeper histories and larger treasuries fight for the same developers, the same users, the same market position. Ethereum has been building for a decade. Solana has institutional backing and a proven track record. BlockDAG had Kiziloz.
That has proven to be enough.

The decisions that built BlockDAG into a contender were not comfortable. Letting a CEO go is not comfortable. Restructuring teams mid-development is not comfortable. Imposing timelines that force people to perform at their limits is not comfortable. But comfort is not the metric. Results are the metric. And the results show a blockchain that now stands as a legitimate alternative to networks that have been building for years longer.

Kiziloz has spoken about his approach with characteristic bluntness. Not everyone is designed to ride a rocketship, he has said. The implication is clear: those who cannot handle the velocity will be left behind, and he will not slow down to wait for them. This philosophy has shaped BlockDAG's culture from the top down. Speed is not a preference. It is a requirement. Execution is not aspirational. It is mandatory. The standards are clear, and the consequences for failing to meet them are equally clear.

What makes this remarkable is not the philosophy itself, other founders have preached similar gospels. What makes it remarkable is that Kiziloz has actually implemented it. He has made the cuts. He has absorbed the friction. He has maintained the pace. And he has delivered a blockchain that can now be mentioned in the same sentence as Ethereum and Solana without the comparison being laughable.

That sentence would have been impossible two years ago. BlockDAG was a concept, an architecture, a whitepaper with ambition. Today it is infrastructure. Today it processes transactions in parallel while Ethereum's users pay congestion fees. Today it offers developers a faster foundation without sacrificing the decentralisation that Proof-of-Work provides. Today it exists as proof that the blockchain vertical, for all its difficulty, can be conquered by someone willing to do what conquest requires.

The industry is filled with founders who wanted to build the next Ethereum. Most of them are gone. The ones who remain have learned that wanting is not enough. Vision is not enough. Even funding is not enough. What matters is execution, the daily, grinding, unglamorous work of turning plans into products and products into platforms. Kiziloz understood this from the beginning. He understood that blockchain rewards the relentless and punishes the hesitant. He built BlockDAG accordingly.

There will be more challenges ahead. Blockchain does not stop testing its participants. Competitors will respond. Regulators will scrutinise. Communities will demand. But BlockDAG enters this next phase from a position that few predicted it would reach: as a serious player in a serious industry, built by a founder who treated every obstacle as a problem to be solved and every underperformer as a cost to be eliminated.

Gurhan Kiziloz did not ask the blockchain industry for permission to compete. He did not wait for validation from incumbents or approval from institutions. He built BlockDAG with his own capital, his own vision, and his own uncompromising standards. The vertical that breaks most founders has not broken him. It has revealed him.
And he is just getting started.
