What’s the best choice between BFT and a DAG ledger for a private supply chain?

[Charles_A]

I’m trying to build a simple proof-of-concept for a supply chain using a permissioned blockchain, but I’m stuck on whether to use a traditional BFT consensus or try a newer DAG-based structure for the ledger. The directed acyclic graph approach seems faster for our validation nodes, but I’m not sure if it’s stable enough yet for even a small private network.

We tried a small private network with a BFT style ledger and it felt predictable, like you could pin down finality in a few seconds and keep going. For a PoC that calmness mattered.

Could the real bottleneck be the data model or how permissions are handled, not the consensus itself?

We played with a DAG idea for validation and it looked faster on paper, but the finality story got hairy in practice and we spent days patching edge cases.

I kept wandering into how we onboard partners and verify identities, and that changes what the ledger needs to do. Still, the question of which approach actually wins on latency sticks.
