#Bitlayer is a quite special network; it does not start from scratch to create a new system but is directly built on the foundation of Bitcoin, effectively adding a layer of "auxiliary system" to Bitcoin.

Everyone knows that Bitcoin is the big brother in digital currency, safe and reliable, and it has not encountered major issues over the years. However, it also has some inconvenient aspects: for instance, the transaction processing speed is not very fast, and its functions are relatively simple, only allowing for transfers or storage. It does not originally support complex operations that require automatic execution (like smart contracts that execute payments automatically when certain conditions are met).

Bitlayer aims to solve these problems. As an "auxiliary layer," it allows Bitcoin to become more flexible and capable while maintaining its original security: on one hand, it can process more transactions, similar to adding more lanes to a narrow road, making it less likely to get congested; on the other hand, it enables Bitcoin to support more complex smart contracts, allowing developers to create various applications, such as decentralized exchanges and lending tools similar to those on Ethereum.

It achieves this through a technology called BitVM. Simply put, this technology acts like an "expansion interface" for Bitcoin, allowing it to support more complex computations and operations without altering the fundamental security of Bitcoin itself. This way, developers do not need to learn something new; they can adapt applications they previously developed on Ethereum to work on Bitcoin with minimal modifications, which is much more convenient.

In summary, the role of Bitlayer is to make Bitcoin more capable and user-friendly while maintaining its greatest advantage of being "safe and reliable," enabling it to support a wider variety of functions and applications. #Bitlayer
