Yesterday, members of the community issued a new proposal on the RAM market model. He believes that RAM should be paid according to the number of uses. The more you use, the more you pay, so there is no speculative behavior. The cost of RAM will also follow the network. Direct changes in memory requirements. In this regard, BM pointed out in the telegraph group that the model proposed by the member is not feasible. He said: The supply of RAM is limited, about 1.5TB, and it is necessary to allocate RAM over time. If our goal is to reduce RAM costs, we should focus on increasing the supply and output of RAM. In other words, I fully support BP to increase the RAM expansion speed by 2 times, to 128GB per year or 2KB per block.
