Challenge Protocol: enhancing security for Fiamma's Bitcoin bridge
Fiamma introduces the Challenge Protocol, a security mechanism for its Bitcoin bridge. It uses fraud challenges and economic incentives to ensure trust-minimized BTC transfers without relying on a majority honest assumption. The protocol enhances security by allowing participants to dispute invalid transactions, reinforcing decentralized enforcement.

BBBB Blog 004: Challenge Protocol
From previous blogs, we understand that the Challenger plays the most crucial role in the Bridge protocol. The entire protocol’s security is predicated on having at least one honest Challenger. Given the importance of Challengers, we aim to increase the number of active Challengers in the operation of the Bridge. To achieve this goal, we propose:
1.Lowering the barriers to entry for becoming a Challenger;
2.Incentivizing the honest actions of Challengers:
· Including verification of true claims;
· Including challenges to false claims;
3. Allowing sufficient time for Challengers to identify malicious behavior and initiate challenges.
