Definition
A monolithic blockchain is a blockchain architecture where a single base layer is responsible for all core functions of the system, including transaction execution, consensus, data availability, and settlement. In this design, the same network of nodes validates blocks, executes transactions, and maintains the full ledger state, without splitting these responsibilities across specialized layers or separate chains.
In Simple Terms
A monolithic blockchain is a single-layer blockchain where one main network does everything: it runs transactions, agrees on their order, stores the data, and finalizes results. All key tasks happen together on the same chain, handled by the same group of participating nodes.
Context and Usage
The term “monolithic blockchain” is commonly used when contrasting different blockchain architectures, especially in discussions about scalability and modular designs. It typically refers to Layer 1 systems where execution, settlement, and data handling are tightly integrated into one chain. The concept appears frequently in technical debates about how blocks should be structured, how nodes operate, and how responsibilities are distributed across layers.
