AleaBFT is a highly efficient, peer-reviewed asynchronous Byzantine Fault Tolerance (BFT) consensus protocol that guarantees safety and finality in distributed systems without relying on network timing assumptions (timeouts). It is notable for achieving a practical quadratic communication complexity, allowing it to scale to large networks more effectively than previous asynchronous BFT protocols which often had cubic complexity.

2. Byzantine fault:
When a node behaves arbitrarily, such as sending incorrect
or conflicting information to different parts of the system.
Bugs, network failures, or malicious activity might cause this
behavior.

14. Asynchronous BFT protocols:
• Remove the need for bounds on message delivery times
• Still fall short of gaining practical adoption
(They could not combine good performance with a simple
design that can be readily understood and adopted.)
