Zaki Manian

Public records about the early life of Zaki Manian are sparse, which is common for technologists who rose to prominence through open source communities rather than traditional institutions. He has described himself in interviews and conference appearances as a longtime software engineer with a deep interest in applied cryptography, and his professional footprint places him in the San Francisco Bay Area technology scene for most of his career ^[1].

What is well documented is the intellectual territory he chose. By the early 2010s Manian was working at the intersection of cryptography, distributed systems, and commerce, a combination that positioned him well when public blockchains began attracting serious engineering talent. Unlike many contemporaries who arrived in cryptocurrency through finance or speculation, Manian approached the field as an infrastructure problem: how to make cryptographic systems reliable enough for businesses and ordinary users to depend on ^[1][2].

Because he is a living person whose biography rests mostly on his professional output, any honest account of Zaki Manian facts must focus on that output: the companies he founded, the protocols he helped ship, and the standards efforts he joined. Those are matters of public record, and they form the substance of this biography.

Manian first drew wide industry attention in 2014 as a co-founder of Skuchain, a Mountain View startup that applied blockchain techniques to global supply chain finance ^[2]. The company set out to replace paper-heavy trade documentation, such as letters of credit, with cryptographically verifiable records that banks, buyers, and suppliers could all trust. Skuchain raised venture funding during the first wave of enterprise blockchain investment and became a frequently cited example of the technology being used for something other than currency ^[2][3].

During this period Manian also became a visible advocate for connected-device security. He served as executive director of the Trusted IoT Alliance, an industry consortium that brought together companies including Bosch and Cisco to explore how blockchain-based identity could secure internet of things hardware ^[3]. The role made him a regular presence at industry events, where he argued that machines transacting with one another would need tamper-resistant registries of identity and provenance.

His interests during these years extended into pure cryptography as well. Manian participated in the ZKProof standardization effort, a community initiative launched in 2018 by academic and industry cryptographers to establish common security standards for zero knowledge proof systems ^[4]. That work connected him to researchers whose techniques would later become central to blockchain scaling and privacy.

The chapter that defines most accounts of the Zaki Manian biography began when he joined Tendermint Inc, the company founded by Jae Kwon to develop the software behind the Cosmos Network ^[5]. Cosmos proposed something ambitious: an internet of blockchains, in which many independent, application-specific chains could interoperate rather than compete for space on a single congested ledger. Manian served as director of research at Tendermint, working on the technology stack that included the Tendermint consensus engine and the Cosmos SDK ^[5][6].

He played a visible role in the run-up to the launch of the Cosmos Hub in March 2019, one of the first major proof of stake networks to go live with a large distributed validator set ^[6]. Before launch, the team ran an adversarial testing competition called Game of Stakes, inviting participants to attack the network under real economic incentives, and Manian was among the engineers publicly explaining and defending this approach to hardening the system ^[5][6].

He was also an early and persistent champion of Inter-Blockchain Communication, or IBC, the protocol that allows sovereign Cosmos chains to pass tokens and data between one another. Among Zaki Manian achievements, his advocacy for IBC ranks high: he pushed for the protocol's completion through periods of organizational turbulence, and IBC went live on the Cosmos Hub in 2021, becoming the connective tissue of the ecosystem ^[6][7].

Manian's time inside Tendermint ended in early 2020, when he resigned amid a widely reported governance dispute within the company about leadership and priorities for finishing IBC ^[7]. The episode was covered extensively by cryptocurrency trade press. Manian continued working on Cosmos technology from outside the company, and the ecosystem itself continued to grow through contributions from multiple independent teams ^[7].

Alongside his research role, Manian co-founded iqlusion, a San Francisco infrastructure company focused on securing proof of stake networks ^[8]. In proof of stake systems, validators lock up capital and run servers that propose and confirm blocks; if their cryptographic keys are stolen or misused, both the network and the funds delegated to them are at risk. Iqlusion specialized in exactly this problem, operating validators on the Cosmos Hub and building open source tooling for key management ^[8].

The firm became known within the ecosystem for engineering work in the Rust programming language, including signing infrastructure designed to keep validator keys inside hardware security modules rather than exposed on internet-connected machines ^[8]. This kind of unglamorous safety engineering rarely makes headlines, yet it addressed one of the practical questions that determined whether proof of stake could be trusted with billions of dollars of delegated assets.

Through iqlusion, Manian remained a delegate-facing figure in Cosmos governance, participating in public debates over protocol upgrades, community funding, and network parameters. His willingness to argue positions openly on forums and social media made him a familiar, sometimes blunt, voice in the ecosystem's decision making ^[1][8].

In 2020 Manian turned toward decentralized finance, co-founding Sommelier with entrepreneur Taariq Lewis ^[9]. Sommelier set out to build automated management for positions in DeFi protocols, using a Cosmos-based blockchain to coordinate strategies that execute on Ethereum. The premise was that ordinary users could not realistically monitor and rebalance complex positions around the clock, and that a purpose-built chain could do it for them under transparent rules ^[9].

The project raised institutional venture funding, including a Series A round announced in 2021, and launched its network with a native token used for validator staking and governance ^[9]. Sommelier's architecture, which pairs a Cosmos SDK chain with Ethereum smart contracts through a bridging mechanism, reflected the interoperability thesis Manian had promoted for years: independent chains specializing in particular jobs and communicating with one another rather than one chain doing everything ^[6][9].

Manian used the platform, and his broader public commentary, to argue that automated asset management was a natural next step for DeFi. Whatever the eventual fate of any single protocol, Sommelier extended a consistent through line in his career, taking cryptographic infrastructure that engineers trust and packaging it for people who never want to think about key management or block times ^[1][9].

Assessing a living builder is different from assessing a finished life, yet certain contributions are already secure. Manian belongs to the small group of engineers who carried the Cosmos Network from whitepaper to a functioning economy of interoperating chains. IBC, the protocol he championed, now links dozens of independent blockchains and is routinely cited as one of the few production-grade interoperability standards in the industry ^[6][7].

His influence also runs through people and institutions. Iqlusion's tooling shaped how professional validators secure their keys, the Trusted IoT Alliance seeded ideas about machine identity that persist in enterprise research, and the ZKProof effort he joined helped legitimize zero knowledge cryptography before it became a mainstream scaling technique ^[3][4][8]. Journalists covering Cosmos have regularly sought his commentary, treating him as an informal historian of the ecosystem's technical decisions ^[1][7].

For readers gathering Zaki Manian facts, the fairest summary may be this: he is a builder of plumbing. The systems he worked on, consensus engines, key signers, bridges, and standards, are mostly invisible when they work. That invisibility is precisely the point, and it is the reason his name recurs whenever the history of proof of stake networking gets written ^[5][6].
