I didn't see anyone discuss about it in this forum, but last week Jameson Lopp decide to attack testnet3 network to prove a vulnerability[1]. If you either attempt to use testnet3 recently or follow the news, you probably know it's not easy to obtain testnet3 coins these days. On top of that, recent Runes hype makes some people decide to add arbitrary data to testnet3 blockchain[3]. With some developer discussing new testnet network (not Signet)[4], i wonder how long will testnet3 remain usable and supported.
