What is a Layer 1 blockchain and its role?
A Layer 1 blockchain, or base chain crypto, is a foundational network protocol that independently validates, orders, and finalizes transactions on its own network. These base layers, such as Bitcoin, provide core security and data availability, essential for the wider blockchain ecosystem. They facilitate asset issuance and transaction settlement, allowing other networks and applications to be built upon them.
