We need 1 minute block times, smaller relay fees and smaller minimal miner fees asap.
I fear no one is going to build on BCH if things keep getting changed. What is special about 1 minute blocks?
Imagine someone selling ice cream for BCH to you, but you must wait one block before he handles it to you. In contrast to 1 mintute coins, BCH will get discontinued in these shops.
Anything longer than 3 seconds is too long for street merchants. Double spend proof suffice for this use case.
I would rather see 1 minute block times than experimental technologies no one have seen in practice so far. A few seconds would be of course fantastic, but 1 min is enough for now.
0-conf worked fine on Bitcoin before blocks became full. No merchants lost money with this back then. so saying its untested is not true.
I think you confusing something, because BTC had no 0-conf.
