Definition ∞ A Layer One launch refers to the initial deployment of a new foundational blockchain protocol, often called the base layer, onto a public network. This event marks the moment when the core blockchain, including its consensus mechanism and native token, becomes operational and accessible to users and developers. It represents the establishment of a new independent distributed ledger system. A successful launch is a critical milestone for any new blockchain project.
Context ∞ Layer One launches are significant events in the cryptocurrency space, frequently covered in news as they represent new contenders in the blockchain ecosystem. These launches are often preceded by extensive development, testing, and community building. The performance, security, and decentralization achieved post-launch are closely scrutinized, as these factors determine the network’s potential for adoption and the viability of applications built upon it. The success of a Layer One launch can significantly impact market sentiment and investment flows.
