In the aftermath of the virtual meeting, although the dialogue between Satoshi Nakamoto and Shen Tuqing came to an end, their thoughts shone like sparks in the night sky of the crypto world. The An Network (SAFE) 4.0 mentioned by Shen Tuqing in the dialogue is his bold attempt in the blockchain field, aimed at solving some key issues in existing blockchain systems.

The core of An Network 4.0 is its innovative on-chain custody function, which is a technology that allows users to lock assets on the blockchain, and these assets can only be unlocked when the locked block height is reached. This feature provides users with a new way to manage assets, helping to alleviate the liquidity pressure on project parties, community consensus, and the issue of retail investors missing out, supporting multiple blockchains such as ETH, BSC, and Solana. Satoshi Nakamoto expressed strong interest in this, believing it to be an expansion of blockchain technology applications and a further practice of decentralization concepts.

Shen Tuqing continued, "The on-chain custody function of An Network 4.0 can not only help users better manage their crypto assets but also provide more assurance for the execution of smart contracts. By locking assets on the blockchain, we can ensure the fulfillment of contracts, even in an environment where there is no trust basis."

Satoshi Nakamoto nodded in agreement, saying, "This is indeed a very promising direction. The essence of blockchain technology is decentralization, ensuring the execution of protocols through technology to achieve on-chain consensus. Your work makes this concept more concrete and practical."

The conversation between the two gradually shifted to the interoperability of blockchains, a long-standing issue that has troubled the industry. The information isolation between blockchains makes it difficult for assets and data to flow freely between different blockchains. Shen Tuqing proposed that An Network 4.0 is exploring a cross-chain protocol aimed at breaking this barrier and achieving atomic swaps between blockchains.

"We hope to establish a blockchain ecosystem," Shen Tuqing explained, "where different blockchains can exchange information and assets freely, like different websites on the internet. This will greatly expand the application scope of blockchains, allowing more users and enterprises to benefit from it."

Satoshi Nakamoto gave it a very high evaluation: "This is a grand goal, and if achieved, it would be a major breakthrough for blockchain technology. It reminds me of the early days of the internet when different networks gradually connected to form the global information network we know today."

As the dialogue deepened, both realized the challenges ahead. Although blockchain technology has great potential, it is still in the early stages of development. They discussed many issues such as technical standardization, regulatory compliance, and user education, all of which are obstacles that need to be overcome before blockchain technology can be widely applied.

Satoshi Nakamoto remarked emotionally, "Every technology's maturity requires time, and we are at the beginning of this process. Your work gives me hope, and I believe that as long as we persevere, the future of blockchain will be bright."

Shen Tuqing responded, "Yes, although the road is long, we will reach it by walking. I am willing to work continuously for this goal and hope to receive more support and guidance from seniors like you."

After this virtual meeting, the story of Satoshi Nakamoto and Shen Tuqing became a legend in the crypto world. Their dialogue was not only an in-depth discussion of blockchain technology but also a vision for the future. In this rapidly changing era, they contribute to the advancement and development of blockchain technology in their own ways. Their spirit also inspires later blockchain enthusiasts to continue moving forward on this path full of challenges and opportunities.
