hypercore

Allows downloading only specific blocks of interest, saving bandwidth and storage for large datasets, as highlighted in the sparse replication feature.

Supports live updates as data is appended, enabling secure and fast distribution of real-time data streams across peers, with events like 'append' for immediate notifications.

Uses a flat file structure to maximize I/O performance, ensuring efficient handling of data blocks without unnecessary overhead, as noted in the performant design.

Employs signed Merkle trees for real-time verification of log integrity, providing strong security guarantees against tampering, with features like treeHash and proof generation.
