Definition ∞ Decentralized data layers are distributed networks specifically designed to store and provide access to data in a verifiable and censorship-resistant manner. These layers separate data availability from execution, enabling modular blockchain architectures. They support scaling solutions by offering an efficient and secure repository for transaction data.
Context ∞ The construction of robust decentralized data layers is a key area of innovation for achieving high scalability in blockchain systems. Discussions center on various approaches, including data availability committees and sharding mechanisms, to ensure data remains accessible and verifiable for all network participants without compromising decentralization.
