In today's digital economy era, blockchain technology has gradually become a highly concerned field, and independent public chain development is an indispensable and important link in blockchain technology. The public chain is the infrastructure in the blockchain ecosystem, and its development and construction play a crucial role in the application and development of blockchain technology.
With the gradual development of blockchain technology, the concept of public chain has become increasingly important. Public chain refers to a fully open and decentralized blockchain system where anyone can initiate transactions and participate in the consensus process of the public chain. The emergence of public chains has greatly reduced transaction costs in digital economy fields such as digital currency and digital assets, while also ensuring the security and transparency of transactions, making public chains an indispensable infrastructure in the digital economy field.
