Sharding has advantages and disadvantages. The advantages are obvious: parallel processing and storage splitting. The disadvantages when splitting the network into shards are that the network can be attacked with less resources. Splitting the network in half, the 51% attack becomes a 25%+1 attack in each shard and so on. It is possible to attack multiple shards at once but you need the resources to do this. So how does Elrond solve this?. In order to prevent attacking and malicious behaviour we have created the shards big enough (~800 nodes) so that controlling 2/3+1 from a shard is not that easy. Every epoch (~1day) nodes are shuffled between shards in order to destructure malicious groups. $### million to get 2/3+ 1 in a shard + you would need to replace the validators that are already in, that's without reshuffling that is implemented. There will also be "fishermen" in shards that look for invalid blocks (created by malicious groups that contain maybe double spend transactions) and signal these blocks to the metachain with a proof. Once the metachain verifies the proof the malicious nodes will be slashed (their locked tokens will be in part given to the fisherman and in part burned). Elrond has built a rating system, so that the chances of validators that behave malliciously will be reduced to get to the consensus group and this way having another "check and balance" in its protocol
