Are there any plans for further decentralization of the network or improvements to scalability and throughput capacity in future updates/releases?

Yes, there are plans for further decentralization of the network and improvements to scalability and throughput capacity in future updates/releases.

Zilliqa is committed to further decentralizing its network by introducing more nodes and increasing the number of shards. This will help to improve scalability and throughput capacity. In addition, Zilliqa is also working on a number of other initiatives that will help to improve scalability and throughput capacity.

These include sharding, which will allow for more transactions to be processed in parallel; a new consensus protocol called "Threshold Relay" which will enable faster transaction confirmation times; and a new smart contract language called Scilla which is designed to be more secure than existing smart contract languages. Finally, Zilliqa is also exploring the use of sidechains as a way to increase scalability and throughput capacity. Sidechains are separate blockchains that are connected to the main blockchain but operate independently from it.

This allows for transactions to be processed on the sidechain while still being secured by the main blockchain. Overall, Zilliqa is committed to further decentralizing its network, improving scalability and throughput capacity, and exploring new technologies such as sidechains in order to ensure that its platform remains secure, efficient, and reliable for users.
