Chainlink Co-Founder Sergey Nazarov and the Origins of Chainlink
Few crypto founders are as closely tied to one idea as Sergey Nazarov is to the oracle.
His name comes up whenever smart contracts need real-world data, and more recently whenever banks talk about connecting blockchains.
This article looks at where he came from, how Chainlink began, and what the record does and does not show.
Sergey Nazarov is a co-founder of Chain-link, which he started with Steve Ellis after co-founding SmartContract.com in 2014. Chainlink is an oracle network that feeds outside data to blockchains.
Nazarov is described as CEO of Chainlink Labs, and he is now a prominent voice on how banks might use blockchain infrastructure.
According to his Wikipedia biography, Sergey-Nazarov was born in 1986 in the Soviet Union to engineer parents, and the family emigrated to the United States in the early 1990s.
He graduated from New York University in 2007 with a degree in philosophy and management, then became a teaching fellow at NYU's Stern School of Business.
The common label "founder" is slightly generous. Chain-link has two named co-founders, and Chainlink's original white paper lists three authors, as covered below.

Before blockchain, he worked in startups and venture capital. The biography lists ExistLocal, a peer-to-peer marketplace he co-founded in 2009, followed by a role at FirstMark Capital.
In 2011 he founded QED Capital, an early-stage fund, which went on to launch an email service called CryptaMail and an exchange called the Secure Asset Exchange in 2014.
None of that is unusual for a founder of his generation. What stands out is the thread running through it: marketplaces, trust between strangers and the question of who verifies a promise.
In September 2014, he and Steve Ellis co-founded SmartContract.com. The company worked with Cornell Tech professor Ari Juels on the idea of a decentralized oracle network.
Chainlink's network was reported to have launched in June 2017, and a whitepaper by Ellis, Juels, and Nazarov is dated 4 September 2017.
A follow-up, often called the Chain-link 2.0 whitepaper, appeared in April 2021. A caution on sourcing.
The Wikipedia entry backs its launch and whitepaper dates with citations that are not primary sources, so readers wanting certainty should check the whitepapers on Chainlink's own site.
Chainlink's own short film, "Block Stories: The Chainlink Origin Story," features both co-founders.
It is organized in five acts and describes an idea two college students discussed that grew into a multi-year effort.
In the film, Sergey-Nazarov points to the 2008 financial crisis as a motivation, saying it "was a good example of the negative effect of paper promises."
The second theme is practical. Blockchains could not see real-world data, so contracts that depended on prices or events had nothing reliable to read.
That gap is the problem the oracle network was built to close. Since the film is produced by Chainlink, it is a company narrative and should be read that way.
Chainlink Labs is the company that builds much of the network's technology, and he is reported as its CEO.
Under that umbrella sit products such as Proof of Reserve and the Cross-Chain Interoperability Protocol, covered in theCCIP documentation.
The oracle idea reaches well beyond finance. Verifiable randomness, for example, lets games and collectibles prove that outcomes were not rigged, which CoinGabbar examines inChainlink NFT Use Cases.
In recent years Sergey Nazarov has become one of the loudest advocates for bringing banks and asset managers on-chain.
The Wikipedia biography lists a White House Crypto Summit invitation in March 2025, attendance at the July 2025 GENIUS Act signing, and a February 2026 selection to the CFTC's Innovation Advisory Committee, though some of those items rest on thin sourcing.
Press listings also showed him on the Sibos 2026 program, where much of the conversation centered on tokenization.
The commercial case follows from that. Tokenized property, funds, and bonds all need trusted data and cross-chain settlement, a theme explored inChainlink and Real World Assets.
Developments on the CCIP side, including DeFi integrations, are tracked in CoinGabbar'sChainlink News coverage.
Much of what circulates about the Chainlink co-founder is repeated from a handful of sources.
Many of the headline claims come from Chain-link itself, from interviews or from Wikipedia entries with weak citations. Three points deserve care:
Company narratives are promotional by nature. The origin film and press releases present the best version of events.
Roles and titles vary between sources, so the exact phrasing of "founder," "co-founder," and "CEO" should be checked at the primary source.
Speculation is not evidence. Online theories about his identity or holdings are unverified, and this article does not rely on them.
Anyone tracking the token alongside the founder's story should also remember that forecasts are opinions.
The Chainlink Price Prediction page covers the market side with that caution.
Sergey Nazarov's story is, in the end, a story about one stubborn idea: that blockchains need a trustworthy way to see the outside world.
From NYU and early startups to SmartContract.com and Chain-link, the through-line is consistent.
The detail is less so, because many dates and titles rest on secondary sources and company-produced material.
A careful reader checks the whitepapers, the official Chainlink site, and filings before repeating a claim and treats founder profiles as context, not as investment advice.
