  Due to the low numbers of nodes that support XTHIN blocks, initially it is a good idea to find a node which is XTHIN capable and

  the `connect-thinblock` feature is mainly used for the purpose of testing, however in some cases it can be useful for very bandwidth

  +### The thinblock mempool limiter
  +
  In order to keep the size of the XTHIN bloom filters from getting too large, a way to limit the size of mempools was implemented in v0.12.1
  using a simple rate limiting technique. If the size of the mempool grows to 3X the size of the largest block seen then two things happen,
