  6 2016-10-16T00:47:36  <dgenr8> if peers are building on first-validated, miner has to balance the tx fee against the increased risk that peer will fail to finish validating his block first.  this might just push up fees.
  7 2016-10-16T00:49:45  <alpalp> why would a peer fail to validate his first?
  8 2016-10-16T00:50:04  <alpalp> peer would need to validate 2 blocks instead of 1?
  9 2016-10-16T00:59:47  <dgenr8> parallel validation is being considered in some quarters
 10 2016-10-16T01:16:15  <alpalp> not sure how that applies.  My fee thing was more a hypothetical.  I might prefer one block at same height over another for many reasons

 32 2016-10-16T03:15:21  <luke-jr> dgenr8: it doesn't make much sense to measure actual validation time in light of compressed blocks..
