update for beem: make beem/beempy ready for tails

Repository

https://github.com/holgern/beem

beem is a python library and command line tool for HIVE. The current version is 0.24.15.

There is also a discord channel for beem: https://discord.gg/4HM592V

The newest beem version can be installed by:

pip install -U beem

Check that you are using hive nodes. The following command

beempy updatenodes --hive

updates the nodelist and uses only hive nodes. After setting hive as default_chain, beempy updatenodes can be used.

The list of nodes can be checked with

beempy config

and

beempy currentnode

shows the currently connected node.

Changelog for 0.24.15

• Add diff_match_patch dependency again, as the difflib implementation does not work

Changelog for 0.24.14

• Add option add_tor to config storage, which allows it to use beempy in tails
• Switch from pyyaml to ruamel.yaml
• Remove Events requirements, beem.notify and beemapi.websocket, as it is not well tested and there are no websocket api nodes available on hive
• Remove unnecessary requirements (pylibscrypt and future)
• add new node (fin.hive.3speak.co) and change change rpc.esteem.app to rpc.ecency.com
• Replace diff_match_patch by difflib and add unit tests
• Increase timeout and retry count in beempy
• Remove obsolete replace_hive_by_steem parameter
• skip_account_check added to account.transfer and account.transfer_to_vesting

Reduce dependencies

The pylibscrypt, future and diff_match_patch dependency has been removed and pyyaml was replaced by ruamel.yaml.

skip_account_check can speed up transfer and transfer_to_vesting

When setting skip_account_check=True the receiver account name is not checked for validity. This reduced the number of API-calls when broadcasting a lot of transfers.

The use_tor config can be set to True for using beem in Tails

Tails is a secure portable operating system that can be started from any PC with USB.

Changing the account keys of a Hive account can only be done with the owner key. Thus, this key needs to be protected from leaking. Broadcasting the account_update operation from Tails could increase security and protect the owner key.

It is possible to activate tor by:

beempy set use_tor true

so that beempy can be used in Tails.

You need to set an administrator password on startup and install the following packages in the root terminal:

apt install build-essential libssl-dev python3-appdirs python3-click-plugins python3-dev python3-future python3-pip python3-pretty-yaml python3-prettytable python3-pycryptodome python3-pytest-runner python3-ruamel.yaml python3-scrypt python3-setuptools python3-websocket

and download the following tar.xz files with the Tor-Browser:

• click-shell from pypi
• beem from pypi
• diff_match_patch fro pypi

This is necessary as a pip install do now work in Tails.

You need to unpack them with tar xvzf file.tar.gz and do a

python setup.py install --user

inside the unpacked directory using a terminal.
This has to be done at first with click-shell, diff_match_pach and then with beem.

The beempy command can be started with

~/.local/bin/beempy

After doing

~/.local/bin/beempy set use_tor true

everything should be working.

I will prepare a more detailed instruction for how to use beempy in Tails.
