In this era of globalization, cross-border remittances have become a daily routine for many families. A mother is intently staring at the mobile banking interface, carefully checking the long address made up of letters and numbers. This is not an ordinary bank transfer, but a Bitcoin remittance, destined for her daughter studying in the UK.

Time is running out, and the rent is about to expire. My mother recalls her last experience using Ethereum for a transfer and can't help but feel a bit worried. That time, due to network congestion, the funds were stuck in the cross-chain process for three days and incurred considerable fees. In the end, she had to seek help in the international students' parents group to resolve the issue.

This time, she decided to try a new solution. On the screen, the progress bar moved slowly, and suddenly a message popped up: "The transaction has been verified by global nodes and is expected to arrive within 5 minutes." This simple explanation relieved her: "It's like dividing the money into countless small parts and sending them to the destination from different routes. Even if one route is blocked, the others can still go through."

In the evening, during the discussion in the parent group about the recent transfer experience, a member engaged in blockchain development explained: "This new technology is built on the basis of Bitcoin with a 'fast lane'. Bitcoin itself is very secure, but it's like a single lane that can easily become congested. The new technology is like adding multiple layers of elevated bridges on top, and it also uses 'fragmented proof of storage' technology, which maintains the security of Bitcoin while greatly improving the transfer speed."

He further explained that the underlying layer is still the Bitcoin blockchain, like a solid foundation; on top is a new network layer made up of countless small nodes. "Your transfer is split into fragments stored on these nodes, so you don't have to wait for the entire blockchain to confirm, making it faster. Moreover, it can directly interface with other blockchains, like an elevated bridge with interchanges, making cross-chain transfers naturally more convenient."

The advancement of blockchain technology often stems from the practical needs of daily life. Just like the evolution from remitting money through the post office to mobile transfers, people now require a smoother "digital remittance channel". The goal of this new technology is to enable ordinary users to easily and securely complete cross-border transfers without having to delve into complex technical details.

This story demonstrates how technology changes our daily lives. A mother's care and a simple transfer operation are backed by complex technological innovations. This is not just about the advancement of financial technology, but a vivid example of how to better serve human needs with technology.
