Parent Blockchain

Chain

A Parent Blockchain represents the foundational distributed ledger upon which subsequent blockchains, often termed ‘child chains’ or ‘layer-2 solutions’, are constructed, establishing a hierarchical relationship critical for scalability and specialized functionality. Its security model and consensus mechanism directly influence the derived chains, acting as the ultimate source of truth and settlement for transactions occurring on those layers, impacting the overall system’s robustness. The selection of a Parent Blockchain is a strategic decision, factoring in throughput, transaction costs, and the developer ecosystem to optimize for specific derivative applications.
