The blockchain data layer stores all transactional and historical information within a distributed ledger system. It comprises a sequence of cryptographically linked blocks, each containing a collection of verified transactions. This foundational layer ensures the integrity and immutability of data across the network, forming the permanent record of all activities. Its design is central to the security and transparency of any blockchain.
Context
Current conversations regarding the blockchain data layer often focus on solutions for scalability, data availability, and storage efficiency, particularly for layer-2 protocols and rollups. Developments in data sharding and alternative data availability schemes are key areas to monitor, as they directly influence the practical application and performance of blockchain networks. Optimizing this layer is critical for wider adoption.
This new modular paradigm uses Random Linear Network Coding on uncoded data, yielding dramatically stronger data availability assurances for light nodes.
