Aviran Vargas
Chicago, IL 60606
Office: 464-300-3001
Aviran Vargas offers exceptional REAL-WORLD expertise in crypto mining and ASIC hosting, backed by his proven track record as a trusted expert witness in legal proceedings. He is the active Director of Operations and Infrastructure at EZ Blockchain, a Chicago-based cryptocurrency hosting company, where he manages live Bitcoin mining infrastructure every single day. With more than 15 years of experience in traditional data center engineering and crypto hosting operations, and over 25 years working hands-on in the field, he possesses in-depth, practical knowledge gained through daily management and complex profit-and-loss accountability. Aviran offers what others cannot: ACTUAL HANDS ON DAY TO DAY EXPERIENCE. Do you want to overcome an expert with 30 certificates, 50 degrees and multiple theoretical credentials? Hire an actual crypto operator with real experience in day to day Operations, Maintenance, Deployment, Moves, Decommissions, Support and all aspects of Crypto Hosting and Mining.
Aviran has been retained six times as an expert witness in cryptocurrency hosting and bitcoin mining disputes. He has testified four times and has given five depositions. His engagements include federal litigation and multiple American Arbitration Association (AAA) proceedings. In Crypto Infiniti v. EZ Blockchain, a $15 million federal jury trial in Chicago, the jury returned a unanimous defense verdict in favor of his client on all claims, including fraud, breach of four contracts, unjust enrichment, and constructive trust. Across his engagements, which center on cryptocurrency hosting and operational disputes, he has provided clear, evidence-based testimony addressing the deployment, maintenance, decommissioning, and operational optimization of ASIC hardware, as well as the assessment of damages and financial losses. His contributions consistently exceeded expectations, delivering valuable support to counsel and helping resolve complex matters in favor of his clients.
Unlike many experts who rely primarily on theoretical knowledge or academic understanding, Aviran has confronted the actual, high-stakes challenges that arise in live crypto mining environments. Theoretical training often fails to capture the full scope of real-world difficulties encountered in operations. He has rebutted experts holding multiple advanced degrees and numerous industry certifications with ease, relying entirely on his deep practical experience and proven results from managing real mining operations.
He has written more than 1,000 pages of detailed operational documentation, processes, procedures, manuals, and technical reports covering every major aspect of crypto hosting operations. This includes logistics, infrastructure design and scaling, customer support protocols, ASIC hardware maintenance, RMA processes, site reliability engineering, power and cooling optimization, inventory management, and performance metrics tracking.
Aviran's extensive background distinguishes him from many other crypto operation experts. He currently oversees a portfolio of more than 60 MW of mining capacity across multiple U.S. facilities, consistently maintaining high uptime, robust security, and scalable performance for ASIC hardware across Bitcoin and other ASIC-dependent networks. His combined experience in traditional enterprise data centers, including Tier IV environments at the Chicago Mercantile Exchange and a Comcast National Data Center housing more than 21,000 servers, and his current crypto mining leadership, reinforced by the thousands of pages of processes and procedures he wrote and implemented, provides a comprehensive perspective that enables him to explain intricate technical and operational issues with precision and clarity in a courtroom setting.
Ultimately, no amount of theoretical study can substitute for the insight gained from personally managing real profit-and-loss outcomes, daily operations, uptime requirements, equipment failures, power constraints, cooling challenges, and team performance under intense pressure.
