Bitlayer, as an important innovative project in the Bitcoin ecosystem, aims to integrate the security of Bitcoin with the scalability and programmability of modern blockchain systems. It employs advanced technologies, such as ZK Rollup technology, allowing the Bitcoin network to have smart contract capabilities. BTR, as the native token of the Bitlayer ecosystem, has a total issuance of 1 billion tokens and plays an important role in ecosystem incentives and governance. Users holding BTR can not only participate in governance decisions within the ecosystem, including proposal voting and parameter adjustments, but also receive ecosystem incentives to encourage more people to participate in the construction of the Bitlayer ecosystem. The launch of the BTR presale on Binance Wallet will undoubtedly bring more vitality and attention to the Bitlayer ecosystem, as well as provide new opportunities for investors.
