This paper presents a partially synchronous BFT consensus protocol powered byBBCA, a lightly modified Byzantine Consistent Broadcast (CBC) primitive. BBCAprovides a Complete-Adopt semantic through an added probing interface to alloweither aborting the broadcast by correct nodes or exclusively, adopting themessage consistently in case of a potential delivery. It does not introduce anyextra type of messages or communication cost to CBC.  BBCA is harnessed into BBCA-CHAIN to make direct commits on a chainedbackbone of a causally ordered graph of blocks, without any additional votingblocks or artificial layering. With the help of Complete-Adopt, the additionalknowledge gained from the underlying CBC completely removes the voting latencyin popular DAG-based protocols. At the same time, causal ordering allows nodesto propose blocks in parallel and achieve high throughput.  BBCA-CHAIN thus closes up the gap between protocols built by consistentbroadcasts (e.g., Bullshark) to those without such an abstraction (e.g.,PBFT/HotStuff), emphasizing their shared fundamental principles. Using aBracha-style CBC as an example, we fully specify BBCA-CHAIN with simplicity,serving as a solid basis for high-performance replication systems (andblockchains).
