UPDATE: We've reset testnet to block 4000 and have already spinned up about 60 MNs on the new testnet. The old testnet is still there and mining continues for some time to give integration partners more time to switch to the new testnet. However, the old testnet doesn't have enough MNs anymore, so features like InstantSend or governance are not working.
For everyone who wants to continue testing the v13 upgrade process, this is the new plan:
1. We downgrade all nodes (including MNs) to v0.12.3.4, which we released a few minutes ago. This version contains only changes for the testnet reset and is equivalent to v0.12.3.3 when used on mainnet. Upgrading on mainnet is not required! (DCG's MNs are already downgraded)
2. A few community members perform the same downgrade and spin up their MNs. Please note that these MNs have to be setup with the old way! This means, you have to use the old guides that currently apply for 0.12.3.x. As this is not a v13 release, none of the "protx" commands will work.
3. We test that everything is working as expected
4. We repeat the whole DIP3 deployment plan with all the stages described further below. This means that we start to upgrade nodes to v13 (RC9, which is not released yet)
Github release for v0.12.3.4:
https://github.com/dashpay/dash/releases/tag/v0.12.3.4
To downgrade to this version, simply install the new version as usual and start it with "-reindex-chainstate", or alternatively start with a fresh datadir. You should also consider starting with a fresh wallet.dat as well, as all payments received so far will not be present in the new testnet. To connect to good nodes, invoke the RPC "addnode 18.202.52.170:19999", this should allow you to sync. When we update the dnsseeder, this step won't be required anymore.
Faucets are not updated yet, which leaves you with no funds for testing and running MNs. If you need 1000 tDash, please ping me in #testnet-lab or write a post with a tDash address here. Make sure to generate addresses with the new wallet which is on the correct chain.
Please ignore RCs for v13 until we give notice about RC9. This means, ignore the following lines until we release RC9. RC8 is incompatible to the new testnet and will be stuck when we stop mining for the old testnet.
