In recent years, the United States has seen continuous innovation in the Blockchain technology field, with several local public chain projects leading the industry development. Here are five highly followed American public chain projects:

First of all, Solana from California has been widely used in the DeFi and NFT fields due to its high performance and low cost.

Secondly, Avalanche, originating from New York, provides efficient and secure infrastructure for decentralized applications with its unique consensus mechanism.

Thirdly, Kadena, as an enterprise-level public blockchain, adopts the innovative Chainweb consensus mechanism, which enhances transaction throughput through parallel processing. The project was founded in 2016 in New York by Wall Street veterans, and its native token KDA plays an important role in the ecosystem.

Fourth, Aptos is an emerging public chain developed by former members of the Meta (formerly Facebook) team, attracting widespread attention in the industry due to the team's rich experience.

Finally, Chainlink, as a pioneer of decentralized oracle networks, has played a key role in connecting blockchain with real-world data since its launch by SmartContract in San Francisco in 2017.

These projects demonstrate the United States' strength in blockchain technology innovation, with each project having its unique technical characteristics and application scenarios, collectively promoting the rapid development of the blockchain industry. As these public chain projects continue to evolve, we can expect to see more innovative applications and solutions emerging, further driving the popularization and application of blockchain technology.
