Recently, there have been new innovations in the Bitcoin ecosystem. Nubit @ nubit_org has launched Bitcoin Thunderbolt, which can make Bitcoin faster and more flexible. Simply put, it means making Bitcoin not just a "piggy bank", but also able to play smart contracts and new gameplay like Ethereum. This upgrade is a Bitcoin Native native network upgrade, and security still relies on Bitcoin itself. It just adds new features, which will make on chain development much more convenient. Various new applications such as USDT transfers, on chain DeFi, and even L2, which are commonly seen in our daily lives, have the opportunity to land in the Bitcoin ecosystem. The emergence of Thunderbolt can be considered as an "evolution" of Bitcoin, and many developers and OGs are excited. The significance of this upgrade is that it not only adheres to the original nature of Bitcoin, but also avoids the trust costs and security risks commonly seen in traditional scaling solutions. Solutions like Babylon and Bitlayer require BTC to be locked or converted into other tokens through a custodial bridge, leading to significant user dependence on third parties. Once incentives are reduced, user churn becomes severe. In contrast, the Bitcoin Thunderbolt promoted by Nubit allows BTC to directly participate in smart contracts and on chain transactions, maintaining its trustless nature, while all transactions are completed on the main chain, bringing more commission income to miners and enhancing network security and long-term value.
