Concerns on increasing the block size

Although increasing the block size is an intuitive approach to increase the transaction throughput, there are some concerns with this approach. Here are some of them:

• Exchanging block data will become more difficult because of the increased size

• Increasing the block size is an immediate solution but not a permanent one

• Changing the block size will result in a hard fork and may risk consensus failures

• Larger blocks will require higher bandwidth to exchange data, which may not excite ordinary full node users and may no longer maintain the full blockchain due to the increased maintenance cost
