The Exploration phase for Pt24m4xi.....(Athens A) will end on block level 39216.
We have a supermajority to test the winning proposal (Athens A)
This means that when the exploration phase (https://tzscan.io/proposals) ends the Tezos chain is forked with a test chain and the 004-Pt24m4xi binaries must be used on this test chain. The main chain still remains on the 003 binaries
The node can support both the main and the test chain. To enable the test chain on your current node you should run it with --enable-testchain
or add "enable_testchain": true
in the p2p section of the node config.json
and restart the node
When we enter the testing phase the node with test chain enabled will automatically follow both chains.
I am not 100% sure about this, maybe someone can confirm, but the baking rights in the test chain are the same that they are on the main chain. So if you have the baking/endorsing right on the main chain you also have this right on the test chain.
This means that bakers who really want to test the new protocol (and keep the test chain going) should be also baking on the test chain.
For the purpose one needs to use the 004 binaries. You can start them with the options –chain test
So for the baker :
tezos-baker-004-Pt24m4xi --chain test run with local node [path to tezos-node] [account]
You can already start it now (in addition to the 003 binaries) and it will say something like Waiting for the test chain to be forked
Reminder : bakers should be extra careful with double baking
You can also separate the setup and there is a really good how-to on

When the test goes well we still need to vote to Promote the new protocol, if this does not reach super majority we will stay on the 003.
