dag package holds the core DAG-chain production logic. The necessary components to ensure ever-growing DAG of (compact)
blocks with availability certification. The DAG doesn't interpret data(batches) anyhow and only ensure they are
available locally(through Certifier).
dag/block holds block and block id structure with respective serialization. The block mainly consists of hashes to
parent blocks(thus DAG) and batch hashes(thus compact).
dag/quorum contains stake-weighted quorum and actual certificates implementation. Quorum defaults to 2f+(where f is 1/3)
fault tolerance. It guarantees every round(height) produces blocks with at least 2f+1 power(by summing stakes of each
block producer) and that every block gets at least 2f+1 signatures.
Below u can see the difference between the regular blockchains and DAG-chains in the diagram. The DAG-chain have multiple proposers in per chain height, whereas in regular chains proposers are rotated. In-turn, this provides better censorship resistance, lack of central point of failure and higher data throughput.
