As a result, there are incentives structure distorted and critical inefficiencies/vulnerabilities (e.g. misallocation of block space, blockspace value destruction, disincentivized simple transaction, centralization around complex transactions originators). Price of blockspace should be the same for any data (1 byte = 1 byte, irrespectively of location inside or outside of witness), e.g. 205/205 and 767/767 bytes in the examples above. Perhaps, the solution (the same price, "weight" of each bit of a transaction) could be introduced as part of the next version of Segwit transactions. Let's fix it. What do you think?
