This release brings two new features and updates the dated default representative and default node.
Local work generation
When creating blocks (when sending or receiving nano or changing the representative), the nano network wants to see a small proof of work. Until now, atto tried to obtain this work from the configured node, using the work_generate action. Because this is costly, some nodes do not support this action. These nodes could previously not be used with atto.
Now atto is able to also generate the required proof of work using the CPU of your computer. If you've got a slow CPU, this might take a few minutes when sending nano or changing your representative, but receiving nano should always be relatively fast (64 times faster than sending to be exact).
The default is now to try fetching the proof of work from the node, but if that fails, generating it with the CPU. You can change this default in the config.go files of atto and atto-safesign.
Querying the representative
You can now query the current representative of an account using atto representative (without any further arguments).
Updated default node and representative
Since the previous default node, https://proxy.powernode.cc/proxy, went offline, the default has been changed to https://rainstorm.city/api.
The previous default representative, Finland Green, also went offline. Thus the default has been changed to NanOslo (nano_1jtx5p8141zjtukz4msp1x93st7nh475f74odj8673qqm96xczmtcnanos1o).
