Alex Mizrahi is a co-founder and CTO of Chromia, a blockchain platform supporting decentralized applications. A computer scientist and software developer, Mizrahi has been involved in blockchain technology since its early stages, with work spanning tokenization protocols and smart contract systems. ^{[1] [3]}

Education

Alex Mizrahi attended Donetsk National University from 2000 to 2005, where he obtained a Master of Science degree in Applied Mathematics. ^{[3] [4]}

Career

From 2003 to 2009, Mizrahi worked as a researcher at the Ukrainian National Academy of Sciences, focusing on algorithmic optimization and computational theory, which later influenced his blockchain-oriented projects

In 2009, he joined AltexSoft, a software engineering firm, as a Lead Developer. During his tenure, he managed the development of customized software solutions for clients in sectors such as travel and logistics.

Mizrahi began working in blockchain technology in 2013. He briefly served as CTO of Safello, a Stockholm-based Bitcoin exchange, where he helped design security protocols. Later that year, he became Lead Developer at Openland, contributing to blockchain-based land registry systems designed to support transparency initiatives.

In 2014, Mizrahi co-founded ChromaWay, a blockchain development company. During his time at ChromaWay, he contributed to the creation of the "colored coins" protocol on Bitcoin, an early method for representing digital assets on a blockchain.

As CTO of ChromaWay, Mizrahi led the development of Chromia, a blockchain platform released in 2019. Chromia integrates relational database structures with decentralized architecture and includes Rell, a programming language developed for the platform to simplify coding processes for decentralized applications. ^{[2] [3] [4] [1] [5] [6]}

Interviews

Alex Mizrahi on Chromia’s Future Plans #01

In a July 9, 2024, interview with DLNews, Alex Mizrahi discussed Chromia’s relational blockchain technology and its advantages over competitors like Polkadot, Cosmos, and Solana. He highlighted Chromia’s ability to efficiently organize and query large datasets, enabling features such as targeted NFT airdrops in a single transaction. Mizrahi emphasized the platform’s use of relational databases, a well-established technology in traditional applications like Reddit and Uber, to attract developers to build scalable decentralized applications (dApps).

Mizrahi also addressed the challenges of centralization in some blockchain ecosystems, noting that Chromia’s architecture reduces reliance on third-party services by organizing data on-chain. He explained the concept of “enhanced digital assets,” such as NFTs with on-chain metadata, which enable greater interactivity within dApps.

Regarding Chromia’s modular architecture, Mizrahi described how its network of specialized chains allows for parallel scaling, predictable costs, and customizable fee structures. He also discussed the platform’s zero-gas fee model, which simplifies user onboarding by allowing developers to cover hosting costs through various revenue models.

Looking ahead, Mizrahi outlined Chromia’s post-launch priorities, including ecosystem growth and user feedback integration. He noted that multiple projects are already in development on Chromia, with further upgrades and product offerings planned to expand the platform’s functionality. ^[7]

Alex Mizrahi on Chromia’s Relational Database #02

In a March 11, 2019, interview on the ChromaWay channel, Alex Mizrahi, CTO of ChromaWay, discussed the technical foundations and advantages of Chromapolis (now Chromia), a blockchain platform designed to support decentralized applications (dApps). Mizrahi explained that Chromia’s use of a relational database framework, built on the Postchain protocol, allows developers to model complex applications more efficiently. This approach simplifies data management and enables powerful transactions that can affect multiple accounts simultaneously, streamlining processes in areas like finance and gaming.

Mizrahi highlighted Chromia’s multi-blockchain architecture, where each dApp operates on its own blockchain. This structure enhances scalability, resource management, and flexibility, enabling dApps to communicate and share data while maintaining independence. He also emphasized the platform’s user-friendly cost models, where dApps can absorb hosting fees, reducing transaction costs for end-users.

Key features discussed included the Rell programming language, designed for relational database interactions, and the platform’s ability to handle high-bandwidth communication between dApps. Mizrahi noted that these innovations position Chromia as a practical solution for developers building scalable, cost-effective decentralized applications. ^[8]

Alex Mizrahi on Innovation in Decentralized Applications #03

In a September 11, 2019, interview with BLOCKTV NEWS at the Decentralized Applications Development Day (D&DD) conference in Tel Aviv, Alex Mizrahi, CTO of Chromia, discussed the challenges and opportunities in the decentralized applications (dApps) space. Mizrahi emphasized the importance of improving usability and accessibility to drive broader adoption of dApps. He noted that while technical limitations have hindered growth, addressing these issues can create a more robust ecosystem.

Mizrahi highlighted Chromia’s focus on simplifying dApp development, making it easier for developers to create applications that are both functional and appealing to mainstream users. He pointed out that user-friendly interfaces and seamless experiences are critical to attracting users who may find traditional blockchain platforms complex.

The interview also underscored the value of conferences like D&DD in fostering collaboration and idea exchange among developers and industry leaders. Mizrahi stressed the importance of informal interactions and networking, which can lead to innovative solutions and partnerships. He expressed enthusiasm for learning from peers and staying updated on industry trends to adapt to the rapidly evolving blockchain landscape. ^[9]
