#内容挖矿升级 Looking at the development history of Blockchain, we can clearly see four key stages of its architectural evolution.

First of all, Bitcoin, as the pioneer of Blockchain 1.0 era, laid the foundation for decentralized digital currency. It became a leader in the crypto world due to its security and reliability, but it also faces challenges in scalability and processing speed.

Following closely, Ethereum led the arrival of the Blockchain 2.0 era. By introducing smart contract functionality, Ethereum greatly expanded the application scenarios of blockchain, evolving from simple value transfer to complex program execution. This innovation provided the technical soil for the vigorous development of emerging fields such as DeFi and NFTs.

As the industry continues to evolve, the Blockchain 3.0 era focuses on enhancing scalability as its core objective. Platforms like Cosmos and Polkadot adopt different technological routes in an attempt to address the throughput limitations of blockchain networks while maintaining the essence of decentralization. Innovations at this stage open up possibilities for broader application scenarios.

Today, we are entering the Blockchain 4.0 era, characterized by the realization of cross-chain interoperability. At this stage, seamless connections and asset circulation between different blockchain networks become the focus, which could fundamentally change the way digital assets are used and the model of value transfer.

Each iteration of blockchain technology is a response to the limitations of the previous generation, expanding the boundaries of possibilities through innovative solutions. From the initial value storage to today's complex ecosystem, blockchain is continuously reshaping our understanding and interaction with the digital world.

As technology continues to evolve, we have reason to expect that blockchain will bring fundamental changes to more industries, creating unprecedented value exchange and collaboration models.
