   qhf: Is it true that Monero has a hard fork every 6 months?
   ahf: Monero used to have 2 network upgrades (hard forks) a year, but this is not the case anymore. The choice of the biannual hard forks was taken in order to be able to introduce important consensus changes, which added privacy features and network-wide improvements (For example @bulletproofs and CLSAG both required a hard fork) and avoid the ossification of the protocol. Recently, the biannual hard forks included changes to the PoW algorithm, to preserve ASIC-resistance.
   ahf1: The dev community and the Core Team agree that the protocol is stable and mature enough and biannual hard forks are not necessary anymore. Furthermore, the ecosystem around Monero has grown exponentially during the years and frequent protocol changes would be increasingly hard to coordinate, could be detrimental to the growth of the ecosystem and to the user experience. Cherry on the top, the new algorithm @randomx is ensuring long term ASIC-resistance, so regular changes are not needed anymore. Network upgrades will still be used to add important protocol improvements and consensus changes, but at a lower and less strict frequency (every 9-12 months).
