Is alphatestnet.z.cash down?


#1

I was running some nodes on the testnet and none of them can currently connect to alphatestnet.z.cash Is it down?


#2

Surprise!

https://z.cash/blog/new-alpha-release-equihash-and-founders-reward.html

Make sure to pull and check out the zc.v0.11.2.z2 branch of our repository, as we've updated the code and it is no longer compatible with the old testnet.


#3

To add to ebfull's info:

For our upcoming alpha releases, we're not going to go to extra effort to maintain backwards compatibility nor maintain old-versioned-testnet nodes, so if you're on the testnet be prepared for breakage around once a month or so.

Once we get close to launch we'll want to start testing and practicing interop and compatibility between releases.


#4

Exxxcellent.

btw I wonder what extravagance the founders will get up to with their testnet bounty...

More seriously though, thank you to the developers for pushing ahead.


#5

I recompiled using the zc.v0.11.2.z2 tag and my nodes are connected again. However, the networkhashps is reported as 0 and blocks are being mined rapidly (though I am getting none). Is the testnet operating as expected?


#6

I think the testnet is working properly. Ensure that you deleted your ~/.zcash/testnet3/ directory and try another sync. The difficulty was set very low for the genesis block but the difficulty adjustments should sort everything out.


#7

All my nodes appear to synced to the reset test blockchain - block number 7887 a few moments ago. I have tried sending some coins from the testnet faucets http://testnetfaucet.zcash-contributions.org/zcash-faucet/ and http://zcashfaucet.xyz/#one but nothing is arriving.


#8

I don't think those faucets were updated. :frowning:


#9

But give me your address (or hop in IRC) and I can send you some!


#10

Thanks! Please try sending some coins to mjwvgA6s9r5wdDgfq3BNvs9RMNqrhPKZHP


#11

Sent you 1000 testnet-ZEC (ZET?). :slight_smile:


#12

Success! I received the coins (see transaction details below).

Maybe the new RAM requirements are too much for my nodes running in the cloud, and I am just not mining effectively.

The RAM requirements on testnet mining are currently very low, so it shouldn't be a problem. You can watch your own miner's progress by adding debug=pow to your bitcoin.conf.


#14

I added the debug=pow line to my bitcoin.conf and am following the debug.log with less +F ~/.zcash/testnet/debug.log, but I am not seeing any pow messages. Generate is definitely set to true. I do see messages about unsupported network nodes, e.g.,

#15

Are these messages related to pow?

Yes, those are the PoW messages, showing the Equihash solver running :slight_smile:


#17

Yep, I am seeing some more

So I am at a lost as to why I have not mined a block yet.
