This is not true, since xthin/compactblocks have been introduced we
completely removed this bottle-neck.
The transactions will be validated continuously, in parallel and not just
when a block is found.

If I understood correctly, OP was not talking about the process inside a node being single threaded, but instead that the whole bitcoin distributed system behaves as single threaded computation. OP seems to be describing a system closer to what IOTA uses, by distributing among the miners the task of validating the transactions. Although, without more specific details, it is hard to judge the benefits.


If the goal is reducing the delay for validation then I don't get what advantage there would be vs. reducing the difficulty.

Also it is my understanding that with the Lightning network transactions could be validated instantly by third parties and could be subject to smaller fees overall...
