In 2006, Alex Beregszaszi launched Siqon, a software consulting company focused on multimedia and financial applications. He played a key role in building browser plugins for online payments, integrating payment gateways, and developing video encoding and playback systems. Alongside this venture, he co-founded Datira and Anesso, taking on the role of Chief Technology Officer (CTO) for both until 2010. These experiences deepened his knowledge of software architecture and financial technology, shaping his future work in the field.
Embedded Systems at Payzone Ireland
In 2010, Alex Beregszaszi became an Embedded Software Engineer at Payzone Ireland, later stepping into the position of Lead Systems Architect (Embedded). He was responsible for designing secure embedded payment solutions working on point-of-sale (POS) terminals, embedded gateways, and backend systems running on Windows. This experience strengthened his expertise in secure financial transactions and payment infrastructure, knowledge that would later play a key role in his work with blockchain-based financial systems.
Blockchain Research
As interest in blockchain technology grew, Beregszaszi co-founded Signatur in 2014, one of the first companies in Ireland to focus on blockchain research. Signatur worked with well-known financial institutions through programs like the Fintech Innovation Lab and the NDRC Launchpad. The company explored ways to use blockchain for financial applications that didn’t rely on central authorities.
Financial Innovation
In 2015, he started BLEND, a company that developed blockchain technology-based payment cards. His goal was to connect blockchain with regular financial systems to create safer and more efficient payment options. His early projects in blockchain reflected his creative approach to improving financial technology.
Contributions to Ethereum and Solidity
In 2016, Beregszaszi became part of the Ethereum Foundation, where he played an important role in improving Ethereum’s execution system and smart contract programming language. As the Lead of EWASM and Co-lead of Solidity, he enhanced Ethereum’s performance, security, and overall structure.
He was also an active member of the EthereumJS team, creating essential tools like the Ethereum JS-vm wallet and making major contributions to Ethereum JS-vm. Over time, he took on more responsibility in Solidity’s design and compiler development, helping to improve the language and grow the team working on it.
Co-Founding Spearbit Labs
Beregszaszi co-founded Spearbit Labs in October 2021 with blockchain security becoming more important. The platform connects security professionals with Web3 projects that require audits and assessments to strengthen their systems.
As both Chief Technology Officer (CTO) and Chief Product Officer (CPO), he led efforts to develop security-focused solutions. He also helped launch Cantina, a company focused on creating specialized tools and services to enhance crypto security.
Leadership at Ipsilon
In 2022, Beregszaszi took on a leadership role at Team Ipsilon, where he focused on making the Ethereum Virtual Machine (EVM) work better. His research aims to improve how efficiently Ethereum processes transactions, making the network more secure and able to handle more activity. By working on upgrades to Ethereum’s core system, he is helping to shape the next stage of smart contract technology.
Making Ethereum Faster and Safer
In an episode of Fluence, Alex Beregszaszi talks about Fizzy – A Deterministic Interpreter, a tool that runs WebAssembly (WASM) programs for Ethereum and blockchain. Fizzy is made to be fast, small, and reliable, making sure it gives the same results on different computers in a network. Beregszaszi explains why Fizzy was created, how it works, and how it helps smart contracts run better. Fizzy improves how Ethereum handles transactions by making things more secure and efficient.
Vision for the Future
Alex Beregszaszi wants to help build a safer, faster, and more reliable decentralized world. With experience in software development, blockchain, and security, he focuses on making smart contracts and digital finance more secure and easier to use.
Through his work on Ethereum, Solidity, and blockchain security, he aims to improve Web3 technology so more people can trust and use it. As a leader at Team Ipsilon, Spearbit, and Cantina, he is working to create better and safer blockchain systems, ensuring the technology continues growing and improving.
Final Thoughts
Alex Beregszaszi’s journey from software engineering to blockchain shows how much he has helped Ethereum grow. His work on Solidity, Ethereum’s system, and blockchain security has improved smart contracts.
