When Chris was asked to comment on Blitzcash becoming (one of the first) sidechain(s) on the Stratisplatform this was his answer:
"When I said the first sidechain I meant the first externally deployed and maintained sidechain! Which has still not been created, we are available to assist and support the blitz team in deploying one but we cannot force then unfortunately"
Seems like the initiative lies with the Blitz community?
