Building a BFT JSON CRDT
Metadata
Highlights
- Thus, CRDTs cannot model anything that requires maintaining global invariants.
- This approach has two major components we need to grasp:
How we ensure Byzantine nodes don’t tamper with messages and pretend to be someone else (hashes + signed message digests)
How we ensure messages don’t get blocked from reaching honest nodes (eager reliable causal broadcast with retries)
