Let’s talk about sharding:
Cross-shard transactions need to pass messages between different shards to coordinate their completion. They’re generally more complex and slower than transactions within a single shard.
The challenge with sharding is security: each shard is managed by only a subset of validators, so attackers can more easily concentrate their efforts on a single shard than attack the entire chain.
