Will sharding allow for a much lower gas limit?

Question

The current gas costs are for all nodes to process a transaction or contract function call. Once we have sharding, only a subset on the nodes(1 shard) will process that transaction/contract function call. So is it safe to assume that gas costs will basically be current gas costs/total number of shards?

Answer 1

Sure, assuming total tx's stay the same, then it will be something like current gas price / shards. I would assume that total tx's will increase however, when sharding goes into effect.

But yes, overall, as a scaling solution, sharding is meant to decrease load on each individual node, and decrease gas prices.

Answer 2

The gas price will tend to be lower since more transactions can be processed per second, while with efficiency improvements such as EWasm and a two layer account trie inside a single trie and a more efficient blob serialization mechanism, the gas limit can increase.
