A Beacon in the Blockchain Domain – Co-founding Ethereum

The year 2013 marked a significant milestone in Dr. Gavin Wood’s professional trajectory. Teaming up with eight other forward-thinking individuals, including Vitalik Buterin and Anthony Di Iorio, Wood co-founded Ethereum, a project destined to revolutionize the blockchain industry.

Ethereum was conceived as a platform to extend the potential of blockchain technology beyond just being a digital currency, as was the case with Bitcoin. It was designed to allow developers to build decentralized applications, or dApps, on a blockchain platform, effectively pioneering the concept of ‘Blockchain 2.0’.

As the project’s Chief Technology Officer, Wood was instrumental in translating the vision of Ethereum into reality. It was under his technical stewardship that Ethereum’s primary language, Solidity, was developed. Wood’s involvement didn’t stop at software programming; he also wrote the Ethereum Yellow Paper, a seminal document that meticulously outlines the Ethereum Virtual Machine’s (EVM) specifications, setting a new standard for blockchain protocol documentation.

The successful launch of Ethereum in 2015 solidified Wood’s position as a significant contributor to the blockchain domain. Under his guidance, Ethereum introduced smart contracts to the world, a revolutionary feature that automated contractual obligations and laid the groundwork for a new era of blockchain applications. Ethereum’s novel approach to utilizing blockchain technology ushered in a wave of innovation, demonstrating how blockchain could transform various industries, from finance to supply chain management and more.

The Genesis of Polkadot

In 2016, Dr. Gavin Wood embarked on a new venture, demonstrating his unwavering commitment to the blockchain industry. He conceived Polkadot, an ambitious project intended to address some of the most pressing issues confronting the blockchain space – namely, interoperability and scalability. Recognizing the growing need for a more connected and efficient blockchain ecosystem, Wood founded Parity Technologies, a core technology firm dedicated to developing the Polkadot network.

Central to Gavin Wood’s vision for a decentralized web, Polkadot was designed to address inherent issues in earlier blockchain technologies. Striving to create a more robust, secure, and scalable platform, Wood championed an approach that set Polkadot apart from its peers.

Polkadot’s architecture, termed a “heterogeneous shared multi-chain,” allows multiple blockchains, known as parachains, to run simultaneously while remaining secure and validated under the umbrella of Polkadot’s relay chain. This multi-chain structure facilitates an increased level of scalability and interoperability, enabling blockchains to communicate and share information in a secure and reliable manner.

The flexible nature of Polkadot is another key attribute of its design. The platform supports upgrades without necessitating hard forks, thereby mitigating the disruptions and divisions that such forks often bring about in blockchain communities. It also empowers individual parachains to have their own governance structures, creating a level of autonomy within the overarching Polkadot system.

Governance within Polkadot is another distinguishing factor. Polkadot is governed on-chain by its stakeholders, enabling the system to evolve organically over time. This inclusive governance model underscores Wood’s philosophy of decentralization, while ensuring the platform can adapt to future needs and challenges.

Beyond Polkadot – Substrate and Kusama

Gavin Wood’s blockchain innovations extend beyond the creation of Polkadot. In pursuit of an adaptable, customizable, and robust blockchain infrastructure, Wood led the development of Substrate, a framework that would further enrich the Polkadot ecosystem.

Substrate was designed as a modular framework, aimed at giving developers the freedom to customize their blockchain while still enjoying the advantages of shared security and composability. The framework is the building block for creating blockchains compatible with the Polkadot network. The philosophy behind Substrate aligns with Wood’s vision of empowering developers and fostering a diverse, decentralized web.

Concurrent with the development of Substrate, another project was born from the same vision — Kusama. Often referred to as Polkadot’s “canary network,” Kusama serves as a testbed for developers, allowing them to experiment and test their blockchain projects in a real-world environment before launching them on Polkadot. The creation of Kusama underscores Wood’s commitment to fostering an inclusive and secure ecosystem.

Both Substrate and Kusama have been instrumental in bolstering the Polkadot network. They have provided a platform for developers to innovate and experiment, thereby contributing to the evolution of the blockchain landscape. 

The Introduction of Parathreads

Another noteworthy addition to the expanding universe of Polkadot, designed by Gavin Wood, is the introduction of parathreads. The inception of parathreads emanates from a solution-oriented mindset, demonstrating once again Wood’s ability to anticipate, identify, and address potential challenges in the blockchain arena.

Parathreads were conceived to rectify two inherent challenges in the original design of Polkadot. The first challenge revolved around the expiration of parachains, also known as the retirement problem. In Polkadot’s structure, parachains bid for slots to gain access to the network’s shared security. When the lease period ends, questions regarding the parachain’s future and its security arise. The second challenge was the high financial entry barrier for projects to obtain a parachain slot, which could potentially exclude deserving projects from benefiting from the Polkadot network.

Parathreads emerge as an ingenious solution to these problems. Unlike parachains, parathreads do not require slot bidding. Instead, they operate based on a pay-as-you-go model, utilizing Polkadot network resources only when necessary. This provides a cost-effective alternative for projects that do not require continuous connectivity to the network. It also offers a feasible transition path for expired parachains, allowing them to convert into parathreads and continue their operations without the need to maintain a full-time slot.

The parathread model is reflective of Wood’s commitment to promoting inclusivity within the Polkadot network. It presents an opportunity for diverse projects to partake in the shared security and interoperability of Polkadot without the financial burden of securing a permanent slot. This innovation reinforces Wood’s reputation as a creative problem solver, always striving for the improvement and evolution of the Polkadot ecosystem.
