Each shard is responsible for processing a part of the transactions, allowing multiple transactions to be executed in parallel, thereby increasing the throughput of the entire  network. Sharding technology enables blockchain to achieve higher scalability without sacrificing security and immutability."}]}],"pr":"685764b15778a78ed8e08c6cdeb7a7fcee13bedc5e13ea7d08c3ebefae6354c0"}
