Odaily News Gavin Wood, co-founder of Ethereum and founder of Polkadot, said in a recent interview with Forbes that blockchains that ignore decentralization and resilience should not be considered Web3. Measuring the resilience of a blockchain often comes down to assessing its degree of decentralization, and Wood identified several questions to assess this metric: Who makes protocol decisions? Does governance have clear or low barriers to entry? And the Nakamoto coefficient, which measures how many parties are needed to destroy the network. Finally, Wood drew attention to more "diffuse concepts," such as whether a single entity can define a narrative and "fundamentally transcend the ecosystem and stifle other narratives."
He is satisfied with the decentralization of Polkadot. According to Nakaflow data, Polkadot's current Nakamoto coefficient is 149, which means that at least 149 independent validators are needed to unite to destroy the network. In comparison, some other major blockchains have much lower scores, such as Solana's score of 19 and Ethereum's score of only 2. However, for Polkadot, the high barrier to entry is still a problem.
In addition, Wood also proposed the following five basic criteria for judging the potential of blockchain:
1. Resilience: The cornerstone of Web3, resilience combines cryptography, decentralization, and game theory to protect blockchains from attacks and ensure their long-term stability;
2. Performance: Not just scalability, performance also measures the efficiency of a network in processing and completing tasks;
3. Generality: The ability of blockchain to support multiple applications and programmability;
4. Accessibility: How easy it is for users, developers, applications, and robots to interact with the network;
5. Coherence: The ability of a system to maintain fast and consistent communication within its network.
