Roham Gharegozlou is an entrepreneur and co-founder of Dapper Labs, the company behind products including CryptoKitties and NBA Top Shot. Dapper Labs also created Flow, a public blockchain designed for consumer applications and digital collectibles. Gharegozlou’s work sits at the intersection of licensed entertainment, blockchain infrastructure, and products intended for people who may not use crypto tools every day.
From Axiom Zen to Dapper Labs
Dapper Labs says it was founded in 2018 by Gharegozlou and Dieter Shirley and spun out of Axiom Zen. The team’s earlier CryptoKitties project helped bring NFT collectibles to a wider audience in 2017. CryptoKitties also became an example of how a popular application could put pressure on Ethereum’s capacity at the time. Dapper later built NBA Top Shot under official NBA and players’ association licenses, packaging licensed basketball highlights as digital collectibles on Flow.
These products helped popularize consumer-facing NFT formats, but “digital ownership” has limits. An NFT can identify a token and its onchain history; it does not automatically grant copyright, guarantee that a website or media file will remain available, or ensure that a platform continues operating. Marketplace terms, licensing agreements, wallet custody, and the application’s design determine what a collector can actually do.
Why Dapper created Flow
Dapper Labs developed Flow as a public blockchain for consumer applications. It uses Cadence, a resource-oriented programming language, and also supports an EVM environment. Dapper’s products can use account and payment experiences that hide some blockchain complexity. That can make onboarding easier, but convenience can come with trade-offs in custody, account recovery, and how much control a user has over keys or transactions. Flow is a network with independent validators and developers; it is not the same thing as Dapper Labs or any single Dapper application.
The December 2025 security incident
Flow’s technical postmortem says an attacker exploited a Cadence runtime vulnerability around December 26–27, 2025, to counterfeit tokens; approximately $3.9 million was bridged off the network. Flow says validators halted transaction processing within hours, the network resumed operations on December 29, and a patched runtime was deployed. The postmortem attributes the flaw to type confusion that bypassed Cadence resource checks.
Flow’s later remediation update says 87.4 billion counterfeit tokens were permanently destroyed. The Foundation also said that exchanges restored services after reviewing the response. These are the project’s published reports about its own incident and remediation, not an independent audit of every claim. The event raised important questions about validator coordination, emergency powers, account restrictions, and how users should assess transaction finality. It should not be simplified to “the chain rolled back”: Flow’s postmortem describes a halt and an isolated recovery process that aimed to preserve legitimate transaction history.
Trade-offs and criticism
Consumer-focused design can lower barriers to entry, while licensed collectibles can offer familiar brands and media. At the same time, custodial login and recovery features may give a service provider a role that self-custody users would otherwise hold themselves. Collectors should distinguish ownership of a token from ownership of the underlying media or an ongoing promise of access. The Flow incident also shows why a public network’s governance and emergency response matter alongside its application design.
Social Media Sentiment
A December 2025 r/CryptoCurrency discussion of the Flow exploit included sharp criticism about the incident and questions about centralization and transaction reversals. Some commenters debated whether coordinated validator action should count as a rollback; Flow’s later postmortem describes a halt and isolated recovery, not a blanket reversal of legitimate history. This is an incident-era thread and a limited sample, not a current survey of Flow users or a judgment about Gharegozlou personally.
