Key Features
- Rust-based: Utilizing the Rust programming language.
- GPLv3 Licensed: Open-source and freely usable.
- JSON-RPC & WebSockets: Default ports 8545 and 8546.
- Modular Design: Adaptable consensus mechanisms.
- Built-in Wallet: Integrated cryptocurrency wallet.
Parity’s Impact
Founded by Ethereum co-founder Gavin Wood, Parity contributed to Polkadot’s development. It housed blockchain engineers globally, working remotely.
Proof of Authority (PoA)
Parity used PoA, relying on a list of validators for consensus.
Security Incident
In July 2017, Parity Wallet faced a major security breach, marking a significant event in Ethereum’s history.

The Rise
Parity quickly gained traction as a viable alternative to the official Go Ethereum (Geth) client. Its focus on performance and security, coupled with its modular architecture, appealed to developers and enterprises seeking more control and flexibility over their Ethereum infrastructure. The Rust implementation also provided a perceived layer of security against common vulnerabilities prevalent in other languages.
Parity’s innovative approach led to the development of several key features that were later adopted by the broader Ethereum community, including:
- WebAssembly (WASM) support: Early adoption of WASM paved the way for more efficient and performant smart contract execution.
- Light client protocol: Enabled resource-constrained devices to participate in the Ethereum network without downloading the entire blockchain.
- Advanced transaction management: Offered features like transaction queuing and replacement, improving the user experience.
The Fall
Despite its technical prowess, Parity Ethereum faced significant challenges that ultimately led to its decline and eventual discontinuation. The most prominent of these challenges were:
- The Parity Wallet Hacks: The 2017 and subsequent 2018 vulnerabilities in the Parity Wallet code resulted in the loss of hundreds of millions of dollars worth of Ether. These incidents severely damaged Parity’s reputation and eroded trust in the client. The complexities of the vulnerabilities and the difficulty in recovering the lost funds fueled criticism and controversy.
- Focus Shift to Polkadot: As Parity Technologies shifted its focus towards the development of Polkadot, resources were gradually diverted away from Parity Ethereum. This resulted in slower development cycles and a perceived lack of commitment to maintaining and improving the client.
- Community Fragmentation: While Parity initially attracted a strong community, the security incidents and the company’s changing priorities led to fragmentation. Some developers migrated to other clients, while others felt disillusioned by the lack of support and communication.
- Complexity of Rust: While Rust offered security benefits, its steep learning curve presented a barrier to entry for many developers, limiting the pool of potential contributors.
Legacy
While Parity Ethereum is no longer actively maintained, its legacy remains significant. It pushed the boundaries of Ethereum client development, introducing innovative features and challenging the status quo. The lessons learned from its successes and failures have informed the development of subsequent Ethereum clients and contributed to the overall maturity of the Ethereum ecosystem.
Parity’s contributions to WebAssembly and light client technology continue to be relevant and influential. Furthermore, the security incidents served as a stark reminder of the importance of rigorous security audits and responsible development practices in the blockchain space. Parity Ethereum, despite its eventual decline, remains a crucial chapter in the history of Ethereum, showcasing both the potential and the pitfalls of innovation in a rapidly evolving technology landscape.
