About Me

Aviran Vargas, Crypto Expert Witness

"Documents tell part of the story. Running live mining sites every day is what helps me read them in context."

Aviran Vargas is the Director of Operations & Infrastructure at EZ Blockchain, a cryptocurrency hosting company managing Bitcoin mining infrastructure across multiple U.S. facilities. He coordinates, organizes, and oversees all facility operations, existing infrastructure, and networks, personally responsible for implementing EZ Blockchain's SB3000 container deployments and their day-to-day operation.

Aviran operates real ASIC facilities, manages live hashrate, reviews real hosting contracts, and signs off on real P&L, every single day. That daily operational experience is what he brings to his testimony: he explains how mining facilities, hardware, and hosting arrangements work in practice, in plain language that judges, arbitrators, and juries can follow.

Recent Trial Outcome: March 2025

Esbrook P.C. Secures Complete Defense Verdict for EZ Blockchain in $15M Crypto Infiniti Dispute

Following a multi-day federal jury trial in Chicago involving over 100 exhibits and three cryptocurrency expert witnesses, the jury entered a unanimous verdict in favor of EZ Blockchain on all claims, including fraud, breach of four contracts, unjust enrichment, and constructive trust. Aviran was one of three cryptocurrency expert witnesses at trial.

Disclosure: EZ Blockchain, the defendant in this case, is Aviran's employer. His other engagements, including US v. Kovar and AAA arbitrations, are unrelated to EZ Blockchain.

Common Questions

Frequently Asked

I am an active Director of Operations at a real hosting company; I work with ASIC miners every single day. I have physically deployed, repaired, moved, and decommissioned hardware. That direct, ongoing, daily experience is what shows in testimony. You are hiring someone who was on the floor this week.

Yes. I have been retained by both plaintiffs and defendants. I am retained to provide honest, fact-based analysis regardless of which side hires me. My opinions come from operational reality, not from who is paying. I will not change a technical conclusion based on what a client wants to hear.

Yes. I have done it in a federal jury trial and in AAA arbitration. I break down hashrate, uptime, ASIC hardware, power costs, and hosting agreements in plain terms, tied to the case documents, without oversimplifying the facts that matter.

I work with attorneys nationwide. I travel anywhere in the United States for depositions and trial or arbitration testimony, and travel costs are billed at actual cost. I have managed facilities in multiple U.S. states.

Extensive hands-on experience with Bitmain Antminer series (S19, S19 Pro, S19 XP, S21), WhatsMiner series (M30S, M50, M60, M70), earlier generation hardware and alt coin ASICs. I have managed the full lifecycle (deployment, operation, RMA, and decommissioning) for the ASIC lines listed above. I can speak to firmware, hashboard diagnostics, PSU compatibility, and real-world efficiency under various power and thermal conditions.

Typically within one to two weeks for an initial case evaluation, depending on document volume. If your matter has a tight timeline, contact me directly to discuss availability. I take a limited number of engagements at any one time to ensure each one receives the attention it deserves.

Yes, I served as one of three cryptocurrency expert witnesses in Crypto Infiniti v. EZ Blockchain, a $15M federal jury trial in Chicago (March 2025). Crypto Infiniti alleged breach of four hosting contracts, fraud, unjust enrichment, and constructive trust. I provided real-world operational testimony on ASIC hardware performance and hosting-site operations. After a multi-day trial with over 100 exhibits, the jury returned a unanimous verdict in favor of EZ Blockchain on all claims. The case was tried by Esbrook P.C. (Michael Kozlowski and Alex Kontopoulos), who are listed as references on this site. Disclosure: EZ Blockchain, the defendant in that case, is my employer.

Yes, I am the Director of Operations & Infrastructure at EZ Blockchain, an active role I hold today. I manage live ASIC mining facilities, monitor real hashrate data daily, negotiate vendor and energy contracts, and oversee actual client hosting agreements. The knowledge I bring to expert engagements is drawn from the work I am doing now.

Yes. Attorney references are listed on this website with names and phone numbers. Each is a practicing attorney from a matter I was retained on.

I prepare by working through the record in detail: the documents, the data, and the opposing expert's work. When my opinions on ASIC performance, facility uptime, hosting contract terms, or power management are questioned, I can also draw on daily operational experience to explain how those things work in practice. I have been cross-examined by experienced attorneys, and I answer technical questions directly and in plain language.

I work in live bitcoin mining infrastructure every day, so I can explain from direct experience how mining sites, ASIC hardware, and hosting arrangements operate. Financial and academic experts cover other parts of these cases; I cover the operational side.

For a cryptocurrency hosting or ASIC mining dispute, the most useful materials for an initial review include: the hosting agreement(s) and any amendments or supplemental agreements; power purchase or energy agreements; uptime and hashrate data logs; any RMA or maintenance records; client communications related to performance complaints; financial records showing alleged losses; and the opposing expert's report if one has been produced. The more operational data you can share (actual pool data, power draw records, facility logs), the more precise my analysis will be. Send what you have. I've worked with incomplete records before.
