## Shard Security Assumptions

Shard security assumptions are the foundational requirements and conditions under which a specific shard remains secure against adversarial behavior. Because shards have smaller validator sets, they are more vulnerable to 51% attacks compared to a monolithic chain.

Security assumptions often involve the total amount of stake protecting the shard, the cost of corruption, and the efficiency of the consensus mechanism. In the context of derivatives, these assumptions determine the level of trust a trader can place in the platform's price feeds and settlement.

If the security assumptions are violated, the shard could potentially suffer from data corruption or invalid state transitions. Protocols must be designed to make these assumptions as conservative as possible to ensure maximum protection.

This involves careful analysis of game-theoretic incentives and potential attack vectors. Understanding these assumptions is essential for institutional participants who must assess the risk of trading on a sharded network.
