To understand Gavin‘s impact on blockchain technology, it’s important to understand the evolution of Ethereum. Ethereum was launched in 2015 by Vitalik Buterin, Charles Hoskinson and Gavin Wood himself. It was designed as a platform for executing smart contracts and developing DApps. Ethereum quickly gained popularity due to its flexibility and advanced features.

The evolution of Ethereum has been marked by several major milestones since its launch in 2015. Here is an overview of its evolution:

1. Launch of the Ethereum blockchain: Ethereum was launched in July 2015 by a team led by Vitalik Buterin. It introduced the concept of smart contracts and programmable blockchain, providing a platform for the development of DApps.

2. Mainnet launch (Frontier, Homestead): After the initial phase (Frontier), Ethereum moved to the Homestead phase in March 2016, marking the stability of the main blockchain and the opening to developers and users.

3. The rise of DApps and ERC-20: In 2017, Ethereum saw an explosion in DApps, particularly ICOs (Initial Coin Offerings), thanks to its ERC-20 token standard. This led to a significant increase in the price of Ether (ETH), Ethereum’s native cryptocurrency.

4. Scalability issues and the upgrade to Ethereum 2.0: The issue of scalability has become increasingly pressing as the Ethereum network has grown, leading to issues of congestion and high fees. To address these issues, the Ethereum team has begun work on Ethereum 2.0, a major upgrade aimed at improving the scalability, security and sustainability of the network through Proof of Stake and sharding.

5. Transition to Ethereum 2.0 (2020 – Present): Ethereum 2.0 is a multiphase process, with the first phase, called Beacon Chain, launched in December 2020. This phase introduced proof-of-stake, allowing users to deposit and secure their Ethers in the new system.

6. Transition to Merge: Merge saw the transition from the previous Ethereum Chain (Proof of Work or PoW) to the current Ethereum 2.0 Chain (Proof of Stake or PoS), marking the end of block mining and the full transition to the new system.

The evolution of Ethereum has focused on improving its performance, scalability and security, to become a more efficient and sustainable platform for decentralised applications. This evolution is also designed to solve the problems of congestion and high transaction costs facing the network, while paving the way for new opportunities for innovation in the blockchain ecosystem.

In 2016, Wood left Ethereum to launch his own blockchain platform called Polkadot. Polkadot is a multi-chain platform that aims to solve interoperability issues between different blockchains. It enables different chains to communicate and share data transparently. Polkadot uses a consensus system called ‘Proof of Stake’ to validate transactions.

Polkadot is a blockchain platform developed to promote interoperability between different blockchains. Created by Gavin Wood, Polkadot aims to solve some of the major challenges facing blockchains today. These include scalability, governance and interconnection.

Here’s an introduction to the main aspects of Polkadot:

  • Interconnectivity and heterogeneity: Polkadot offers an innovative approach by enabling distinct blockchains, whatever their programming language or functionality, to connect and work together. This heterogeneous architecture facilitates interoperability between the different chains, enabling the exchange of information and values between them.

  • Parachains (parallel chains) and Relay Chain: Polkadot’s structure is based on a main chain called the ‘Relay Chain’ and secondary chains, the ‘Parachains’. These parachains can be adapted to meet specific needs, offering flexibility and customisation while being connected to the Relay Chain for security and interoperability.

  • Proof of Stake: Polkadot uses a consensus mechanism called ‘Proof of Stake’ to secure its network. Holders of DOT tokens can lock them into the system to validate transactions and contribute to the security of the network, while earning rewards.

  • Governance and evolution: A key aspect of Polkadot is its on-chain governance structure, where DOT token holders have the opportunity to participate in decisions about network upgrades and change proposals.

  • Scalability and security: Polkadot aims to improve the scalability of blockchains by enabling secure parallelisation of transactions on parachains, while maintaining a high level of security via the Relay Chain.

  • Ecosystem and related projects: Polkadot has spawned a dynamic ecosystem comprising several projects built around its infrastructure. These projects exploit Polkadot’s functionalities to create innovative decentralised applications and solve specific problems.

To sum up, Polkadot aims to be an advanced blockchain platform offering interoperability, scalability and decentralised governance. Its modular design and innovative consensus mechanisms make it a major project in the evolution of the blockchain ecosystem.

Gavin Wood’s other contributions to blockchain technology

In addition to his contributions to Ethereum and Polkadot, Gavin worked on other blockchain-related projects.

He founded Parity Technologies, a blockchain software development company that created the Parity Ethereum client. This is one of the most popular clients for interacting with the Ethereum blockchain.

He also worked on the development of blockchain infrastructure, notably as a key contributor to the development of the Kusama network.

Parity Technologies engineers are among the main contributors to the Polkadot network. They are working hard to help deliver a revolutionary Web3 technology, Coretime Agile (estimated time for transaction validation through the Polkadot Relay Chain mechanism), first presented by Dr Wood as an idea at the Polkadot Decoded event in the summer of 2023. He is quoted as saying that this will go live on Kusama [Polkadot’s ‘canary’ network] and Polkadot in the first quarter of 2024.

Coretime Agile fundamentally alters the means by which Polkadot’s key resource, time on parachain cores, is acquired. Rather than long-term leases with difficulties in predicting deposits obtained by auction, Coretime (as the resource is known) is sold at more predictable prices in a monthly sale just prior to its use. Coretime Agile is a major evolution of the Polkadot architecture, offering greater scope and flexibility so that every type of Web3 project can benefit from the advantages of the network.
