On Wednesday I've started a public Hive testnet based on v1.25.0rc1
https://gitlab.syncad.com/hive/hive/-/tags/v1.25.0rc1
Many thanks to 
For now it's just a seed node with default Hive testnet chain-id, but of course it's going to be powered by many other usual components such as hivemind, jussi (and thus fully featured API node), condenser, block explorer, etc.
Anyone can run their own testnet instance and/or join this public one.
p2p-seed-node = testnet.openhive.network:2001
To join testnet with your hived, you need a testnet-enabled version, which you can get from here:
https://gtg.openhive.network/get/testnet/bin
or build yourself (as usual plus -DBUILD_HIVE_TESTNET=ON during cmake step)
