 The primary objective of Resharding V3 is to increase chain capacity by
 splitting overutilized shards. A secondary aim is to lay the groundwork for
 supporting Dynamic Resharding, Instant Resharding and Shard Merging in future

 The sharded architecture of the NEAR Protocol is a cornerstone of its design, enabling parallel and distributed execution that significantly boosts overall throughput. Resharding plays a pivotal role in this system, allowing the network to adjust the number of shards to accommodate growth. By increasing the number of shards, resharding ensures the network can scale seamlessly, alleviating existing congestion, managing the rising traffic demands, and welcoming new customers. This adaptability is essential for maintaining the protocol's performance, reliability, and capacity to support a thriving, ever-expanding ecosystem.
