Scaling

Sharding

• Split network into smaller partitions called shards;

• Nodes are assigned to a shard;

• Nodes don't need to store the entire blockchain anymore;

• Transactions are executed in parallel;

• Increases the number of transactions per second;

• Similar to a highway road with more lanes: more cars can ride simultaneously;

• Layer 1 scaling solution;

• Can help reduce gas fees since network is less congested.
