grep -c 'assumevalid'          src/main.cpp   -> 0

Neither compact block relay nor assumevalid is present.

BIP152 matters more here than it does for Bitcoin: at 2-minute spacing on low
hashrate, propagation delay converts directly into orphans, and orphans on a small
chain are a larger proportion of issuance. assumevalid is a separate, smaller win
for initial sync.

Both are non-consensus and node-local. From Roadmap 2 (topic 24, msg 65).
