Namespace preorder wait in blockstack -regtest?

rocky · February 19, 2018, 12:28am

I am following the instructions in https://github.com/blockstack/blockstack-core/blob/master/docs/namespace_creation.md#registering-a-namespace to create a namespace (in bitcoind -regtest).

The doc says

If all goes well, you will get back a transaction hash.

I did get that back

You should wait for the transaction to be confirmed (~10 confirmations) before sending the reveal transaction.

Since this is private, is there something I have to do to force ~10 confirmations?

After waiting 10 or so minutes, I tried running reveal and got:

$ blockstack namespace_reveal hello "$PAYMENT_PKEY" "$CREATOR_PKEY" "b40dd1375ef63e5a40ee60d790ec6dccd06efcbac99d0cd5f3b07502a4ab05ac"

Does this mean that I don’t have enough confirmations or some other problem?

Thanks.

Hey @rocky, did you start blockstack-test-scenario with --interactive-web 3001? If so, then you should be able to load http://localhost:3001 in your Web browser and tell the test framework to generate more blocks. I’ll update the document to make this clearer.

Hope this helps!

Thanks for the info. It probably advanced things, but I think there is more or something else that is wrong…

I had run with --interactive-web 3001. Following your advice, I opened up a browser then and created maybe 30 or so blocks using the “Generate blocks” button.

I see that the “Blockchain height” has increased. (It is now 723). And I see a lot of debug output in response to generating blocks. The log messages starts:

However running the reveal command still gives an error:

Unless there are other suggestions, message that in the above that I guess I will follow down is

I have just redone everything from scratch and everything works.

I stopped and restarted blockstack-test-scenario,
Issued a namespace preorder
Created 15 or so blocks through the web interface at 127.0.0.1:3001
revealed name namespace

Thanks for the help.

Glad you got it to work!
