We need to note that Etherereum might work through the process of sharding the whole blockchain where the data/blockchain is being split up into various smaller parts and are being run by miners. Devs have suggested that the size of the sharding block which is 16kB now would be upgraded to 128kB.
If the block size increases than the number of transactions getting included in the block increases which in-turn increases the rewards earned by the miner.
Actually this was the future ideology of Bitcoin to be used on a larger scale. If the blocks are able to support more txns, we could very well fit in more txns and subsequently the confirmation would become faster.
My confusion was what is the rate at which this block size is increases? If it is for every 10 min then very soon all transaction will be less to the size of the block or there are chances of even blank block with only the coinbase transaction will be mined.
The size of sharding block increases 8x and this was the one mentioned. The latter part would never happen in current situations. Currently for a network like bitcoin each transaction are being processed at the speed of 7 transactions per second. With majority of users coming into picture and using bitcoin/ethereum we would certainly see a increase in transactions which could be processed faster than usual.
