Creating blocks without work

Support
#1

Hi All,

I'd like to make a block (block_create) without any work attached to it. I have my node's "receive_minimum" set to "1000000000000000000000000000000000000", but work still gets generated whenever I "block_create' or "send" for amounts far below that minimum....

I first edited the config-node.toml file through vim, saved, then restarted my node to be sure the changed config files were updated properly.

How can I create blocks without having my machine do work?

Edit: What I am trying to do is create blocks for something like offline-signing where I can later attach work to the block and publish at that point.

I believe you can set the optional work field to any nonzero value and attach a real work value later. Alternatively, try to set work_threads in the config to 0 on the offline machine where you create blocks.

Ha, that was absurdly simple and worked, thanks!

Yes, I had tried setting work_threads to 1 earlier to see what would happen and since it made everything take much longer, I was nervous that I would stall my node or something by setting to 0. If anyone can confirm whether that's a viable option, that would be nice to know too.

We did some work towards ensuring the node won't stall when work generation is disabled so feel free to set work_threads to 0. This was the PR and it describes the situations covered: https://github.com/nanocurrency/nano-node/pull/2312

For this case however, if you give work 0 or no work, and work generation is disabled, it will error. You really have to force another value, e.g. "1"

Ok, that's good to know. Thanks for letting me know about that edge case too, I would have tripped up on that otherwise.

Thank you for the question, I've added a ticket to RPC 2.0 to distinguish values given as "0" and not giving any value, since they're clearly different intentions.
