docs: <p>Sets the false positive rate of bloom filters given to peers. The default is {@link #DEFAULT_BLOOM_FILTER_FP_RATE}.</p>
  
  <p>Be careful regenerating the bloom filter too often, as it decreases anonymity because remote nodes can
  compare transactions against both the new and old filters to significantly decrease the false positive rate.</p>
  
  <p>See the docs for {@link BloomFilter#BloomFilter(int, double, long, BloomFilter.BloomUpdate)} for a brief
  explanation of anonymity when using bloom filters.</p>
