In 2018, Facebook made a quiet but telling personnel move. It appointed Evan Cheng, a veteran low-level systems engineer who had spent nearly a decade at Apple building compiler infrastructure, as Director of Engineering for its newly formed blockchain division. At the time, the appointment barely registered outside tech circles. Looking back from 2026, it reads very differently. Cheng went on to help lead Facebook's Libra project, later renamed Diem, and after Meta shut that effort down, he co-founded Mysten Labs, the company behind Sui, a Layer 1 blockchain that has since grown into one of the more consequential networks in the industry. Understanding how that single hiring decision unfolded says a lot about how Silicon Valley's biggest bets on blockchain actually played out.

Following a story with this many twists, from a Facebook subsidiary to an independent blockchain success, requires a real technical grounding in how these systems actually work. A recognized Certified Blockchain Expert credential gives professionals the foundation needed to understand why Cheng's background made him such a notable pick in the first place, and what that background eventually produced.

Who Evan Cheng Was Before Facebook's Blockchain Bet

A Career Built On Low-Level Systems Engineering

Before joining Facebook, Cheng spent close to a decade at Apple, most notably leading development on LLVM, a foundational compiler infrastructure project that still underpins software running across billions of Android and iOS devices today. His work there earned him a share of the 2012 ACM Software System Award, a recognition reserved for genuinely significant contributions to computer science. This background in scaling, performance, and throughput problems, the unglamorous plumbing that makes large systems actually work, turned out to be exactly the skill set blockchain infrastructure needed.

Joining Facebook's Programming Languages Team

Cheng joined Facebook in November 2015, initially leading the company's Programming Languages and Runtimes group. He spent close to three years in that role before Facebook moved him into its blockchain division, a signal at the time that the company's blockchain ambitions were being treated as a serious engineering priority rather than a side experiment.

The Move To Facebook's Blockchain Division

Why The Appointment Mattered

Cheng's promotion to Director of Engineering, Blockchain came shortly after a wave of senior technical staff had already departed Facebook's blockchain group, and industry observers at the time read his appointment as a clear signal the company was doubling down rather than scaling back. Recruiting an engineer specifically known for solving scaling and performance problems suggested Facebook understood that cryptocurrency infrastructure would need exactly that kind of technical discipline to work at consumer scale.

Working Alongside David Marcus And The Libra Team

Facebook's blockchain division had been established under David Marcus, previously president of PayPal and a Coinbase board member, who led the effort to explore blockchain applications across Facebook's platform. Cheng became a central technical figure within that group, eventually serving as a key contributor to the Libra project and, alongside co-authors including Sam Blackshear, helping develop Move, a purpose-built programming language for secure digital asset transactions that would later prove far more durable than the Libra project itself.

Understanding the technical and economic reasoning behind a project like Libra, a stablecoin-style digital currency built specifically for global scale, requires real fluency in how cryptocurrency systems actually function. A Certified Cryptocurrency Expert credential builds exactly that kind of grounded, practical understanding, the same kind of knowledge that shaped Cheng's own path from traditional software engineering into cryptocurrency infrastructure.

From Libra To Diem To Novi: A Project Under Constant Pressure

The Rename And Regulatory Struggles

Libra was renamed Diem in an effort to distance the project from earlier regulatory pushback and present a more independent structure to global regulators. Facebook's payments subsidiary was similarly renamed from Calibra to Novi Financial, with Cheng serving as Director of Research and Development at Novi during this period. Despite these efforts, the project faced sustained skepticism from central banks and financial regulators around the world, who viewed a Facebook-backed global digital currency as a significant threat to monetary sovereignty and financial stability.

Why The Project Eventually Wound Down

Diem's path to launch proved difficult enough that a significant number of the team's technical staff grew frustrated and left the project before it was ultimately shut down, with its remaining assets sold off in 2022. For Cheng personally, the experience was described later as one that initially felt like a major opportunity but eventually left him feeling he could not build what he actually wanted to build within Meta's structure.

Building Sui: Where The Diem Team's Work Actually Landed

Founding Mysten Labs

Rather than walking away from blockchain entirely, Cheng and several former Novi Research colleagues, including Sam Blackshear, Adeniyi Abiodun, George Danezis, and Kostas Chalkias, co-founded Mysten Labs in 2021. The company raised more than 300 million dollars across its funding rounds, eventually reaching a 2 billion dollar valuation, and set out to build a new Layer 1 blockchain informed directly by the hard lessons learned during Diem's collapse.

Sui's Real-World Traction

Mysten Labs launched Sui's mainnet in May 2023, and the network has since built genuine momentum, surpassing 500 million dollars in total value locked within its first year and continuing to expand its decentralized finance and gaming ecosystems through 2025 and into 2026. In more recent public comments, Cheng has described his current focus as building a blockchain-based operating system suited for AI and automation, aiming to give humans, machines, and autonomous agents a shared, developer-friendly infrastructure layer, a notably different vision from the consumer payments focus that originally defined Libra.

Building infrastructure capable of supporting that kind of ambition, a blockchain designed to coordinate human and machine transactions at scale, requires serious engineering depth. A structured Tech Certification in blockchain development gives technical teams the practical skills needed to understand and evaluate systems built with this level of architectural ambition, rather than simply taking a founder's roadmap claims at face value.

What This Story Reveals About Big Tech's Blockchain Bets

Cheng's trajectory, from a quiet internal promotion at Facebook to leading one of the industry's more closely watched Layer 1 blockchains, offers a genuinely instructive case study in how corporate blockchain ambitions and independent blockchain innovation often end up intertwined. Facebook's Libra project ultimately failed to launch as originally envisioned, undone largely by regulatory resistance rather than technical shortcomings. Yet the technical talent, tooling, and hard-won lessons from that failure did not disappear. They resurfaced as some of the very infrastructure now powering a genuinely independent, successful blockchain network years later.

Building the Next Generation of Technology Skills

Evan Cheng’s journey from compiler engineering to blockchain infrastructure also shows how foundational technical skills can remain valuable even as technologies and industries change dramatically. Programming, computational thinking, cybersecurity, artificial intelligence, and problem-solving can give younger learners a foundation for understanding emerging systems, whether they eventually work with blockchain networks, autonomous software, AI applications, or technologies that have yet to become mainstream.

Designed to encourage technology learning among school students, the World Tech Olympiad (WTO) brings together participants from Class 2 to Class 12 through different technology-focused challenges. Its areas include robotics, AI, programming, computational thinking, and cybersecurity, with competition levels structured to suit different age groups and abilities.

The Olympiad supports participation through separate routes for families and educational institutions. Parents can enroll their children directly, while schools can register as institutions and facilitate participation for students who meet the eligibility requirements.

Final Thoughts

Evan Cheng's appointment to lead Facebook's blockchain engineering in 2018 looked, at the time, like a fairly routine internal reshuffle. Viewed from 2026, it marks the beginning of a much longer arc, one that ran through Libra's ambition, Diem's regulatory struggles, and ultimately into Sui's genuine market traction as an independent Layer 1 blockchain. The through line connecting all of it is Cheng's consistent focus on solving hard infrastructure problems, whether inside a trillion-dollar tech company or an independent startup built from its ashes.

Telling a story with this many turns clearly, to investors, developers, or anyone trying to understand why a failed Facebook project eventually produced a successful independent blockchain, takes real communication skill. That is where a well-rounded Marketing Certification becomes genuinely useful, helping teams and founders translate a technically complex, multi-year journey like this one into a narrative that stakeholders outside the engineering team can actually follow and appreciate.

His technical background made him relevant to blockchain development because distributed-ledger platforms require expertise in performance, security, programming languages, and complex infrastructure.

4. When did Facebook begin building a blockchain team?

Facebook began assembling a dedicated blockchain team in 2018. The effort was initially led by David Marcus, who had previously overseen Messenger and later became closely associated with Facebook’s cryptocurrency and payments ambitions. The company brought engineers and executives into the group as it explored how blockchain could fit into future products.

5. What did Facebook originally want to do with blockchain?

Facebook initially explored blockchain broadly rather than announcing one specific product. Potential areas included payments, digital assets, identity, financial services, and decentralized infrastructure. The company's ambitions later became more concrete with the Libra project, which sought to create a global digital currency and payment network.

6. How was Evan Cheng connected to Facebook’s Libra project?

Evan Cheng’s move into blockchain engineering occurred before Facebook publicly unveiled Libra in 2019. His work formed part of the broader period in which Facebook was building technical expertise around blockchain and distributed systems. Libra later became the most visible expression of Facebook’s blockchain strategy, although the project went through major regulatory and organizational changes.

7. What was Facebook Libra?

Libra was a digital currency and blockchain-based payments initiative announced by Facebook in 2019. The project aimed to create a global digital payment system supported by a consortium of companies and organizations. Facebook argued that Libra could make payments more accessible and efficient, particularly for people underserved by traditional financial services.

8. Why was Libra controversial?

Libra faced intense scrutiny from regulators, central banks, lawmakers, and financial institutions. Concerns included monetary sovereignty, financial stability, consumer protection, privacy, money laundering, and the possibility that a technology company with billions of users could gain substantial influence over global payments. The regulatory response forced the project to change significantly from its original design.

9. What happened to Libra?

Libra was later renamed Diem as the project attempted to address regulatory concerns and reposition itself as a more compliant digital-payment initiative. Despite those changes, Diem struggled to secure the regulatory approvals necessary for launch. The project was eventually wound down, and its assets were sold in 2022.

10. What was Novi and how did it relate to Facebook’s blockchain plans?

Novi was Meta’s digital wallet project, originally developed to support blockchain-based payments connected to the Libra/Diem ecosystem. It was designed to enable users to send and receive digital money through an easy-to-use wallet. Novi eventually ran a limited pilot using an existing stablecoin rather than Diem before Meta discontinued the service.

11. Did Facebook ever launch its own cryptocurrency?

Facebook did not successfully launch Libra or Diem as a widely available proprietary cryptocurrency. The company developed substantial technology and infrastructure around the project, but regulatory resistance prevented the original vision from becoming a mainstream financial network. This distinction matters because Facebook’s blockchain efforts were serious, but the headline-grabbing global currency never reached its intended scale.

12. Why was Facebook interested in blockchain despite already controlling large platforms?

Blockchain offered technologies that could support global payments, programmable assets, digital identity, and decentralized infrastructure. For a company operating Facebook, Instagram, WhatsApp, and Messenger, payments represented an enormous strategic opportunity. A digital currency could theoretically have enabled people and businesses to exchange value across those platforms without relying entirely on existing banking and card networks.

13. Could blockchain have changed Facebook’s business model?

Potentially. Facebook historically relied heavily on advertising revenue, while blockchain and digital payments could have opened additional businesses around commerce, payments, digital wallets, and financial services. A successful blockchain-based payment network could have made Facebook more deeply integrated into online economic activity. Regulatory concerns, however, made that strategy much harder to execute than the original technical vision suggested.

14. How did regulators respond to Facebook’s blockchain ambitions?

Regulators reacted cautiously because Facebook already controlled enormous amounts of user data and operated platforms used by billions of people. Adding a global digital currency raised concerns about financial concentration and systemic risk. Governments wanted stronger guarantees around reserves, AML, consumer protection, privacy, and governance before allowing such a system to operate at scale.

15. What lessons did Facebook’s blockchain experiment teach Big Tech?

Facebook’s experience demonstrated that building blockchain technology is only one part of launching a global financial network. Regulation, governance, monetary policy, privacy, banking relationships, and public trust can be equally important. A technology company can design impressive software and still fail to launch the product if regulators and financial institutions are unwilling to support it.

16. Did Meta abandon blockchain completely?

No. Although Libra, Diem, and Novi were discontinued, Meta continued exploring areas connected to digital ownership, virtual worlds, creators, payments, and Web3 technologies. The company's broader strategy shifted toward the metaverse and AI, but blockchain-related concepts remained relevant to digital assets and decentralized infrastructure across the technology industry.

17. What happened to Evan Cheng after Facebook?

Evan Cheng later became a prominent figure in the broader blockchain industry. He went on to help found Mysten Labs, a blockchain technology company associated with the development of the Sui blockchain. His career illustrates how technical talent from Facebook’s early blockchain initiative later contributed to independent blockchain ecosystems.

18. Why is Evan Cheng important in blockchain history?

Evan Cheng represents part of the wave of senior engineers from major technology companies who moved into blockchain development during the industry's expansion. His involvement helped demonstrate that blockchain was attracting serious infrastructure and systems-engineering talent, not just cryptocurrency entrepreneurs. His later work outside Meta also contributed to the development of newer blockchain platforms.

19. What does Facebook’s blockchain journey mean for Big Tech in 2026?

Facebook’s experience shows that Big Tech can contribute significantly to blockchain technology while still facing limits imposed by regulation and public trust. Companies such as Meta, Google, Microsoft, and others can build infrastructure, wallets, identity systems, payments, and developer tools, but financial services operate under very different constraints from social media or cloud software. In 2026, blockchain adoption by large technology companies is more likely to appear through infrastructure and integrations than through attempts to launch universal corporate currencies.

20. What is the legacy of Evan Cheng and Facebook’s blockchain engineering initiative?

The legacy of Facebook’s early blockchain initiative is larger than the failure of Libra or Diem.

The company helped move blockchain into serious discussions about global payments, digital wallets, corporate stablecoins, financial inclusion, and the role of technology companies in monetary infrastructure. Its efforts also attracted engineers, investors, regulators, and policymakers who began treating blockchain-based finance as a potentially systemic issue rather than a niche cryptocurrency experiment.

Evan Cheng’s involvement represented the technical side of that transition. Facebook was no longer merely watching blockchain from a distance; it was assigning experienced engineering leadership to understand and build it.

The original strategy did not unfold as planned. Libra became Diem, Diem was abandoned, and Novi was shut down. Yet many of the ideas those projects explored, including stablecoins, programmable payments, digital wallets, and blockchain-based financial infrastructure, became increasingly important elsewhere.

So the more useful historical lesson is not that Facebook successfully conquered blockchain. It is that Facebook’s move helped demonstrate how seriously Big Tech had begun taking the technology, and how quickly blockchain could collide with the far less programmable world of regulation, monetary policy, and public trust.
